I’m Chris Miller, and I came into this Portland Mattress project with a simple goal: find a bed that doesn’t leave my lower back grumbling after long desk days. A lot of mass-market mattresses miss the mark—either too soft and saggy or so rigid they feel unforgiving. Portland Mattress Makers stood out because they build in Maine and lean into traditional innerspring construction, including flip-ready options on several models.
We set the Portland Mattress models up in our test loft and rotated through them in week-long blocks. I moved between back and side sleeping, long laptop sessions, and the occasional short stomach nap. Marcus stressed the perimeter during early-morning shoe-tying and sit tests. Mia stayed in her usual side-sleep curl and called out pressure points quickly. Jenna tracked every ripple from her partner on shared nights. That mix is what shaped this Portland Mattress review.

Product Overview
Here are the four Portland Mattress Makers innerspring models we focused on. Builds and pricing can vary by size and store, so treat the “price” column as general positioning rather than a fixed checkout total. For a broader buying refresher, the Mattress Resource Hub pulls together the basics in one place.
| Mattress | Pros | Cons | Ideal For | Price (Queen, approx.) | Overall Score |
| Newcastle 660 | Firm, steady support; simple feel; strong value positioning | Limited plushness for many side sleepers; lighter comfort layers | Budget shoppers, guest rooms, youth beds | Varies by store, size, and options | 4.0 / 5 |
| Acadia Plush | Balanced comfort and support; smoother pressure relief than Newcastle; built for flipping | Can still read firm for very light side sleepers | Average-weight back and combo sleepers | Varies by store, size, and options | 4.3 / 5 |
| Acadia Pillow Top with Latex | Deep pressure relief; buoyant latex contour; more cushioned feel without “stuck” drag | Higher cost; too plush for strict firm-feel fans | Side sleepers, pressure-sensitive joints | Varies by store, size, and options | 4.6 / 5 |
| Sebago Lake Plush | Support-forward innerspring feel; solid edge stability; good choice for heavier use | Heavier to maneuver; motion isolation trails the thick latex pillow-top option | Heavier sleepers, long-term primary bed | Varies by store, size, and options | 4.5 / 5 |
Testing Team Takeaways
From my perspective, this set felt refreshingly traditional—in a good way. The beds were spring-forward and responsive, with comfort layers that focused more on cushioning than deep sink. On models built to be flipped, we alternated sides and watched for consistency. On the one-sided builds, we focused on rotation, edge sitting, and whether alignment stayed steady night after night.
On the Acadia Plush, back sleep gave me a clear, level “shelf” under the hips with enough surface padding to keep my lower back calm after long editing sessions. Side sleep still read slightly firm at the shoulders, but it didn’t cross into sharp pressure. The Acadia Pillow Top with Latex was the easiest side-sleeping bed of the group, with more give at the shoulder and hip without the slow, sticky feel I associate with dense memory foam.
Marcus tested these with his usual stomach-to-back routine. Under his 230-pound frame, the Newcastle 660 felt straightforward and steady—firm enough to keep his hips from dipping on stomach sleep. Over longer nights, he gravitated toward the Sebago Lake Plush because it held him up while feeling less stark on top. He also spent a lot of time on edge sit tests, and Sebago was the one he could lean into while tying shoes without that “slide off” sensation.
Mia’s feedback came fast. On the Newcastle 660, she called out shoulder pressure almost immediately; it felt too flat and firm for her lighter frame. Moving her to the Acadia Pillow Top with Latex changed the story. She could settle in at the shoulder while her hips stayed aligned, and she liked that the surface responded quickly when she switched sides.
Jenna focused on shared-bed behavior. On the Acadia Plush, she noticed some bounce but not enough to disrupt reading when her partner shifted. The latex pillow-top version damped movement a bit more, though she felt slightly deeper in the top layers during bigger position changes. For her, the Sebago Lake Plush delivered the best mix: easy to move on, yet stable enough that small movements didn’t ripple across the whole bed.
Portland Mattress Comparison Chart
Here’s how the four models compare on feel and performance. Portland Mattress Makers doesn’t publish every technical detail, but the construction approach and on-bed behavior were clear in our testing.
| Mattress | Firmness (1–10) | Type | Profile Height | Cooling Performance | Support | Pressure Relief | Responsiveness | Motion Isolation | Durability Outlook |
| Newcastle 660 | Medium-firm 7–7.5 | Traditional innerspring with a firm, flat feel | Standard medium profile | Moderate to good due to airflow through coils | Strong for back and stomach sleepers | Limited for delicate shoulders | High, quick pushback | Moderate, some bounce felt | Good with regular rotation; durability depends on care and build choices |
| Acadia Plush | Medium 6–6.5 | Flippable innerspring with plush comfort layers | Standard to slightly taller profile | Moderate, breathable quilt | Consistent for average weights | Better than Newcastle for side sleeping | High, easy repositioning | Moderate-high, reduced ripple | Very good; flipping and rotating help spread wear |
| Acadia Pillow Top with Latex | Medium-plush 5.5–6 | Flippable pillow-top innerspring with Talalay latex | Taller profile | Moderate-high; latex helps heat dispersion | Solid for back and combo sleepers | Excellent for side sleepers and joint relief | Medium-high, buoyant response | High; thicker top layers absorb motion well | Very strong; latex and a two-sided build support long-term use |
| Sebago Lake Plush | Medium-firm 6.5 | Support-forward innerspring with added surface cushioning | Taller profile | Moderate; airflow through the coil core | Excellent for heavier sleepers | Good, slightly firmer than the latex pillow top | High, lively coil response | Moderate-high; some bounce remains | Excellent; rotate to help keep wear even over time |
What We Tested and How We Tested It
Our group used the same checklist on every model. The first piece covered support and alignment. I lay on my back for at least fifteen minutes on each surface, then shifted to my side for another fifteen, watching for hip drop or mid-back sag. Marcus extended those sessions for heavier-frame feedback, while Mia covered the lighter side-sleep perspective.
Another pillar involved pressure relief. Mia spent longer blocks on her shoulders and outer hip, then checked for any lingering ache after getting up. I repeated the pattern with my own side sleeping, paying closer attention to hip and lower-back comfort.
We tracked cooling behavior under warm room conditions. Marcus stayed on each mattress with a light sheet and comforter, then described any heat buildup. Cooling impressions came mostly from full nights, not quick showroom-style flops.
For responsiveness and motion isolation, Jenna and her partner ran the standard series: one person rolled in and out of bed, changed positions, and did light bouncing while the other stayed still and rated disturbance. We also used a simple water-glass test near the center and near the edges.
We added targeted checks for edge support (sit tests, tie-your-shoes pressure, and sleeping close to the perimeter) and for firmness (how quickly each surface transitions from quilt comfort to coil pushback).
Durability impressions obviously can’t come from a few weeks alone. For that part, we combined rotation or flipping cycles (where applicable), repeated edge-sitting sessions, and material inspection with what the brand discloses about construction. From that mix, we assigned our review scores later.

Portland Mattress: Our Testing Experience
Newcastle 660
Our Testing Experience
My time on the Newcastle 660 started with a simple question: can an entry-level innerspring keep my lower backneutral without feeling harsh? The surface felt firm and straightforward. On my back, the coils pushed back clearly under my hips, and my lumbar area stayed closer to neutral than it usually does on budget beds.
Rolling to my side told a different story. My hip pressed in more than my shoulder, and I kept wishing for a thicker cushion at the shoulder cap. I could nap on my side here, but for full nights it felt better suited to back or stomach sleepers.
Marcus put the Newcastle 660 through a heavier lens. He sprawled on his stomach, tucked his arms under the pillow, and stayed there in silence. When he finally spoke, he said, “This is firm, almost boardlike, yet my hips are not sinking at all.” For him, that stability mattered more than plush comfort. When he sat on the edge next, the border compressed, but he stayed stable while tying his shoes.
Mia landed on the opposite end of the spectrum. She curled onto her side and within minutes said, “My shoulder feels pinned against the coil layer.” She could tolerate it for short reading sessions, but the feel didn’t suit long side-sleep blocks for her frame.
Midweek, we rotated the mattress to check consistency and to mimic the basic care most innerspring builds expect. The feel stayed predictable, without a dramatic “good side / bad side” difference. Taken together, it reads as a practical choice for guest rooms, kids’ rooms, or adults who want a firmer, no-frills sleep surface.

Acadia Plush
Our Testing Experience
The Acadia Plush sits a step above Newcastle in the lineup, and the difference shows as soon as you lie down. The initial quilt feels softer, but the support underneath stays organized. On my back, I felt a controlled cradle before the coils caught me, keeping my hips up without a hard stop.
On my side, my shoulder finally had a bit more space. It still felt more “traditional innerspring” than “foam hug,” but I could stay put through full sleep cycles without waking up with numbness. Over a week, my lower-back tightness after desk days felt noticeably calmer here than it did on Newcastle.
Mia approached this model cautiously after her Newcastle sessions. She paused on her side, then said, “This kind of surface is still firm, but my shoulder has somewhere to go now.” She described the support as “organized rather than pokey.” For her lighter frame, it landed on the acceptable side for longer nights, though it still wasn’t the plushest feel in the group.
For Marcus, the Acadia Plush hit a middle ground. On his back, he felt more cushion than on Newcastle without losing that solid understructure. He called it “a soft pad over a serious coil engine.” On strict stomach nights, he still preferred Newcastle’s flatter feel, but he liked Acadia for mixed-position weeks.
Because this model is built to be flipped, we swapped sides midweek. The feel stayed consistent, with only subtle quilting differences, which made it easy to rotate the mattress through different testers without a “good side / bad side” bias.
Pros & Cons
| Pros | Cons |
| Balanced medium feel for many sleepers | Could feel firm for very light side sleepers |
| Built for flipping and long-term use | Stomach-only sleepers may prefer a flatter, firmer surface |
| Noticeably better pressure relief than Newcastle 660 | Less plush than the pillow-top latex version |
| Solid choice for a guest room or a primary bed | Traditional build without “flashy” tech features |

Acadia Pillow Top with Latex
Our Testing Experience
The Acadia Pillow Top with Latexwas the clear standout for pressure relief in this group. On my back, I felt a slower, more gradual descent before reaching steady coil support. The latex in the pillow top created a buoyant contour that felt springier and less “sticky” than classic memory foam.
Side sleeping became the main story. I tucked onto my left side and waited for the usual shoulder pressure point. Instead, the pillow top let my shoulder settle and then stopped at a supportive “floor” where the coils pushed back evenly. On longer nights, switching sides felt easy—I didn’t have to wrestle the surface to find a comfortable angle.
Mia’s experience on this mattress matched the name. After a long pause she said, “This feels like a soft pocket with a floor that holds my spine straight.” For her petite frame, the latex finally delivered the give she wanted at the shoulder while keeping her hips aligned. She reported less morning shoulder tightness here than on any other model in the set.
Jenna measured couple-friendliness here. With her partner moving in and out of bed, she noticed fewer sharp jolts than on Acadia Plush because the thicker comfort layers absorbed more energy. She still felt some bounce under quick movement, which she liked, saying, “This kind of response helps me roll instead of swallowing me.” During the water-glass test near the center, we saw small ripples, but the glass stayed upright.
Because both sides use a pillow-top build, flipping didn’t bring the usual “one side is flatter” surprise. The feel stayed close from side to side, which makes regular flipping and rotation easier to stick with over time.
Pros & Cons
| Pros | Cons |
| Excellent pressure relief for side sleepers and sensitive joints | Too plush for those who want a very firm feel |
| Talalay latex adds buoyant contour and helps temperature control | Higher cost than simpler innerspring models |
| Two-sided pillow-top construction supports long-term upkeep | Heavier to flip; may require two people |
| Couple-friendly mix of bounce and motion damping | Back-only sleepers who want an ultra-flat surface may prefer firmer options |

Sebago Lake Plush
Our Testing Experience
Sebago Lake Plush felt like the most support-forward bed in this set, especially under heavier use. On my back, the surface felt taut and stable, with enough quilted cushioning to keep it from reading “bare springs.”
Marcus became the main storyteller here. After a few breaths on his back, he said, “This feels like a stronger engine under a softer seat.” On his stomach, his hips stayed afloat without feeling jammed. Over longer back-sleep sessions, he reported less lower-back fatigue than on Acadia Plush, mainly because the support held steady under his weight.
On my side, Sebago felt supportive but a touch firmer at the shoulder than the latex pillow-top Acadia. It struck me as better for average to heavier sleepers who want resilience than for ultra-light side sleepers chasing deep plushness. Mia confirmed that impression, saying, “This feels secure, yet my shoulder still wants a touch more give compared with the latex pillow top.”
Jenna’s couple-testing highlighted Sebago’s lively feel. Big movements traveled more than on the latex pillow top, but the motion stayed manageable, and repositioning felt easy. Edge behavior stood out as a strength as well. Marcus sat, leaned forward, and twisted to grab his bag without sliding. I knelt near the edge to stretch and felt a solid platform rather than a collapsing border.
Rotating the Sebago Lake Plush took more effort than the others because it’s heavier. We handled it with two people to avoid wrestling the corners. Once rotated, the feel stayed consistent and the surface bounced back quickly after repeat edge sit tests.
Pros & Cons
| Pros | Cons |
| Excellent support for heavier sleepers and taller bodies | Higher cost compared with midrange options |
| Supportive, stable feel with strong edge performance | Slightly firm for very light side sleepers seeking deep plushness |
| Easy to reposition; good fit for active and combination sleepers | Heavier build makes rotating more demanding |
| Solid daily-driver option for long-term use | Motion isolation trails the latex pillow-top Acadia |

Best Picks
- Best Portland Mattress for Side Sleepers – Acadia Pillow Top with Latex
This model earned the spot because it consistently delivered the deepest pressure relief in our set. The Talalay latex pillow top cradled shoulders and hips without sacrificing alignment, which helped both Mia and me stay on our sides through full nights. - Best Portland Mattress for Heavier Sleepers – Sebago Lake Plush
For Marcus, Sebago Lake Plush delivered the most reliable hip and back support. That steady, support-forward feel works well for taller or heavier bodies that can compress softer beds too quickly. - Best Value Portland Mattress – Newcastle 660
If you want a firmer, flatter surface and straightforward construction, Newcastle 660 is the value-driven pick in this group. It’s a good match for sleepers who don’t need deep cushioning and who prioritize support over plushness.
How to Choose the Portland Mattress?
Choosing among these models mostly comes down to sleeping position, body weight, and how much cushioning you want above the coils. If you’re still dialing in basics like firmness and support, start with How to Choose a Mattress and our Mattress Firmness Guide.
From the perspective of a light-weight side sleeper like Mia, Acadia Pillow Top with Latex made the most sense. The latex pillow top shaped around her shoulders while keeping her spine straight. Acadia Plush worked as a backup option if she wanted a more “medium” feel, though she still described that one as “a bit firm” on some nights.
For an average-weight back sleeper, Acadia Plush is the most balanced starting point. It offered clear coil support with enough cushioning up top to soften contact points. The latex pillow-top version also worked well for my back, but some back-only sleepers may prefer the flatter feel of Acadia Plush.
Under hot-sleeper circumstances, the coil-heavy builds stayed relatively temperature neutral for Marcus. If cooling is a priority beyond “not overheating,” you may also want to compare these results with our picks for Best Cooling Mattresses.
For a heavier couple, our testing pointed toward Sebago Lake Plush as the starting point, with Acadia Pillow Top with Latex as a second option for those who prioritize extra cushioning. If you want more context around body weight and long-term support, see Body Weight and Mattresses.
For a guest room or youth bed, Newcastle 660 covers the basics. Its firm, flat feel works well for shorter stays and growing bodies, and it’s an easy pick if you want a traditional innerspring surface.

Limitations
Even when the support is strong, these models won’t fit every preference. If you want an extremely firm, almost unpadded surface, Newcastle may still feel a touch cushioned because of the quilt layer. At the other end, sleepers chasing a cloud-like, ultra-plush feel may find even the latex pillow-top option more structured than expected.
Very heavy sleepers far above Marcus’s range might prefer more specialized support systems than what we tested. Fans of hyper-bouncy innerspring beds with minimal foam may also feel that Acadia Plush and Sebago Lake Plush include more top padding than they want.

FAQs
Are Portland Mattress models good for side sleepers?
In our tests, Acadia Pillow Top with Latex worked best for side sleepers, especially for Mia and for my own side nights. Acadia Plush can also work if you prefer a slightly firmer, more traditional feel, but Newcastle 660 read too firm for most side-only sleepers.
Related Post: The 8 Best Mattresses for Side Sleepers
How long can a Portland Mattress last with real-world use?
Based on the overall construction approach and how the beds held shape during repeat sit and sleep sessions, these models appear built for long-term use. Regular rotation (and flipping on two-sided models) helps spread wear. Support-forward options like Sebago Lake Plush are also a better match for heavier households that wear out softer beds faster.
Related Post: Mattress Durability: How to Choose a Bed That Lasts
Do Portland Mattress models sleep hot?
In Marcus’s view as a hot sleeper, these mattresses stayed relatively temperature neutral. The coil cores allowed airflow, and the latex in the pillow-top Acadia helped disperse warmth. None of the models behaved like dense memory foam beds during our test nights.
Related Post: The 8 Best Mattresses for Hot Sleepers
Which Portland Mattress is best for heavier sleepers?
Sebago Lake Plush came out ahead for Marcus thanks to its steady support and strong edge feel. Newcastle 660 also kept his hips supported on stomach sleep, but Sebago added more surface cushioning for long nights.

Is the Portland Mattress Newcastle 660 too firm for everyday use?
It depends on body type and sleep style. For back and stomach sleepers who like a firmer surface, Newcastle 660 can work well. For petite side sleepers like Mia, it felt overly firm and created shoulder pressure.

How does motion isolation compare across Portland Mattress models?
Acadia Pillow Top with Latex delivered the calmest surface for Jenna during couple tests. Acadia Plush and Sebago Lake Plush followed closely, with some bounce but not chaotic movement. Newcastle showed the most noticeable motion transfer, though many pairs may still find it manageable.
Do Portland Mattress models come in all standard sizes?
Most major sizes are commonly available across these lines, but specialty sizing can vary by store and build options. If you’re comparing room fit and sizing tradeoffs, our Mattress Sizes Guide can help you narrow it down before you shop.
Can one person flip these Portland Mattress models alone?
Lighter builds like Newcastle 660 and Acadia Plush may be manageable for one strong adult with careful technique, but heavier models—especially the pillow-top latex option—are much more realistic with two people. Even when you’re not flipping, rotating a heavier mattress is safer with help.
Are these Portland Mattress options suitable for adjustable bases?
Some innerspring designs can work on adjustable bases, but compatibility varies by build and support system. If you’re planning to pair one of these beds with a power base, confirm compatibility with the retailer and compare with our guide to Adjustable Base setups.

How do Portland Mattress models compare with big online bed-in-a-box brands?
These beds felt more traditional and more responsive than many foam-heavy bed-in-a-box options. Support and edge behavior stood out in our sessions, especially for heavier bodies. The main tradeoff is that trial windows tend to be shorter, and delivery is handled through regional channels rather than compressed box shipping.
