I’m Chris Miller, and this time our team spent real nights on the Heirloom Classic Innerspring Mattress—a flippable, tight-top innerspring that still feels old-school in the best way. With so many mattresses chasing “plush” and “sink,” we wanted to see what a straightforward, two-sided spring build feels like when you actually live on it.

Heirloom Classic at a Glance
| Mattress | Pros | Cons | Ideal For | Price (Queen, approx.) | Overall Score |
| Heirloom Classic Medium Firm | Balanced support, cooler sleep than most foams, and a true flippable build. | Not plush; lighter side sleepers may feel shoulder pressure. | Back sleepers, combo sleepers, and couples who prefer a stable surface. | ~$1,350 | 4.4 |
| Heirloom Classic Firm | Very steady feel with strong posture support and confident edges. | Least pressure relief of the two; can feel unforgiving on your side. | Heavier sleepers, firm-mattress fans, and back/stomach sleepers. | ~$1,350 | 4.3 |
Testing Team Takeaways
Both Heirloom options feel like classic tight-top innersprings: you sleep more “on” the mattress than “in” it. The surface stays fairly level, the coil system adds easy mobility, and the flippable build keeps it from feeling disposable. The real question is how much firmness your body can comfortably handle.
On the Medium Firm option, I got steady lumbar support without feeling jammed at the shoulders. It’s firm enough to keep my hips from dipping when I’m on my back, but it still has a touch of cushion when I roll to my side. Carlos agreed the alignment looked clean and neutral, especially for back sleeping, while noting that strict side sleepers who need deeper pressure relief may want something softer.
Marcus liked the cooler, breezier feel compared with foam-heavy beds. He also called out the edge support—sitting or sleeping near the perimeter didn’t feel sketchy. Jenna and Ethan’s couple testing landed in the middle: motion isolation is better than older linked-coil mattresses, but you still notice movement more than you would on many pocketed-coil hybrids. The upside is that both feels are easy to move on, with none of the “stuck” sensation that comes with dense foam.

What We Tested and How We Tested It
We evaluated both feels using our standard approach to mattress testing: multiple nights of sleep, plus targeted checks for support, pressure relief, cooling, motion transfer, responsiveness, and edge stability. For each category, we compared what we felt in real use with what we could observe when we deliberately pushed the mattress—rolling, sitting on the edge, and testing a range of positions.
Because the Heirloom is flippable, we also paid attention to how the surface responded over time. A two-sided mattress should hold up better than a one-sided tight top, but it still has to feel consistent night to night. We rotated and flipped as recommended and noted how quickly the surface “rebounds” after a few nights of use.
Finally, we scored the mattress the way most shoppers make decisions in the real world: does it keep your spine aligned, does it relieve pressure enough for your sleep style, and do the practical details—temperature, firmness, edges, motion transfer, and policies—fit your household?
Heirloom Classic: Our Testing Experience
Both versions share the same basic construction, so the “feel” change is the main difference. If you like the idea of a flippable innerspring but you’re unsure which firmness to choose, the notes below are the quickest way to match the mattress to your body and sleep position.
Heirloom Classic Medium Firm
The Medium Firm option feels supportive right away, but it’s not stiff. You get a flatter, more buoyant surface than foam beds, with enough cushioning to keep it from feeling like you’re sleeping directly on coils.
Our Testing Experience
On my back, the mattress held my hips in place and kept my lower back from sagging. It’s the kind of firmness that makes it easy to relax—no fighting for a neutral position. When I rolled to my side, I felt more give than I expected from a tight top, but the surface still sits “higher” than a plush hybrid.
Carlos noticed the same thing during alignment checks: back sleeping looked very steady, and combination sleepers got predictable support when switching positions. If you need deep pressure relief for shoulders or hips, though, this is where the Medium Firm can start to feel a bit shallow—especially for lighter side sleepers.
Marcus ran warm and appreciated the airflow you typically get with an innerspring. Temperature stayed more even than on foam-heavy beds. Edge support was another strong point: sitting to put on socks didn’t feel like sliding off, and sleeping near the edge didn’t collapse the surface.
In couple testing, Jenna and Ethan found motion isolation respectable but not “dead.” You feel some bounce and some transfer, yet it’s muted enough for many couples—especially if you’re used to innersprings. Responsiveness is excellent; turning over or changing positions takes almost no effort.
Pros & Cons
| Pros | Cons |
| Supportive, level feel that works well for back and combo sleeping. | Can feel firm at the shoulders for lighter or pressure-sensitive side sleepers. |
| Noticeably cooler sleep than many foam mattresses. | Motion transfer is reduced, but not as quiet as many pocketed-coil hybrids. |
| Strong edge support and easy movement. | Not a plush feel; minimal sink-in. |
| Flippable build that encourages longer-term use. | Adjustable-base compatibility depends on size. |

Heirloom Classic Firm
The Firm option keeps the same flippable innerspring build, but the surface feels tighter and more resistant. If you like a mattress that holds you up and stays flat, this is the version that leans into that preference.
Our Testing Experience
On my back, the Firm feel delivered very clean support—hips stayed lifted and the mattress didn’t compress much under load. For stomach sleeping, it also did a better job keeping my midsection from sinking, which is where many medium mattresses start to bow.
Carlos liked the posture support but flagged the tradeoff: most side sleepers will feel more pressure at the shoulder, especially if they’re lighter or have sharper pressure points. Marcus, on the other hand, preferred the Firm option because his weight engaged the mattress more evenly without making it feel hard.
Couples should expect a bit more motion transfer than on the Medium Firm, simply because the surface is more reactive. It’s still easy to move on and it still sleeps relatively cool, but it won’t mask a partner’s movement the way a dense-foam hybrid can.
Pros & Cons
| Pros | Cons |
| Excellent support for back and stomach sleeping. | Too firm for many side sleepers. |
| Strong edges and a very stable surface. | Pressure relief is lower than the Medium Firm option. |
| Easy movement; no sink-in feel. | Motion isolation is only moderate. |
| Flippable, long-term build. | Adjustable-base compatibility depends on size. |

Compare Performance Scores
| Model | Comfort | Support | Pressure Relief | Cooling | Motion Isolation | Responsiveness | Edge Support | Overall |
| Heirloom Classic Medium Firm | 4.3 | 4.5 | 4.2 | 4.6 | 4.3 | 4.6 | 4.6 | 4.4 |
| Heirloom Classic Firm | 4.1 | 4.6 | 4.0 | 4.5 | 4.2 | 4.6 | 4.5 | 4.3 |
The two options are close in build quality and cooling, but they diverge on comfort. Medium Firm is the safer choice for mixed positions and most couples. Firm is a better match if you reliably want a flatter, more resistant surface—especially if you’re heavier or spend a lot of time on your back or stomach.
Best Picks
-
Best choice for mixed sleepers:
Heirloom Classic Medium Firm — steady support with enough cushion for position changes. -
Best firm option for back and stomach sleepers:
Heirloom Classic Firm — the more stable feel when you want minimal sink. -
Best pick for couples who like bounce:
Heirloom Classic Medium Firm — easier movement with moderate motion damping.
How to Choose Between Medium Firm and Firm
If you sleep on your side a lot: start with Medium Firm. The Firm option can feel sharp at the shoulder unless you’re heavier and naturally compress the surface more evenly.
If you’re primarily a back sleeper: either can work, but your weight matters. Average-weight sleepers tended to prefer Medium Firm for a touch more comfort; heavier sleepers often liked the Firm option’s flatter support.
If you sleep on your stomach: the Firm option is the more reliable pick. Medium Firm is workable for some stomach sleepers, but the Firm feel did a better job keeping the midsection from dipping.
If you share the bed: Medium Firm is usually the better balance. It dulls motion a bit more while still staying responsive enough for easy repositioning.
Limitations
This is not a plush mattress, no matter which feel you choose. If you want a deep cradle or a pillow-top “hug,” the tight-top design will feel too straightforward.
Motion isolation is solid for a traditional innerspring, but it doesn’t reach the level of many modern hybrids with individually pocketed coils and thicker foams. Light sleepers who wake easily from partner movement may want a more motion-dampening build.
Finally, the purchase experience is closer to buying furniture than ordering a bed-in-a-box. Expect longer lead times, freight delivery, and policies that can be more restrictive than online trial programs.
Policies at a Glance
| Model | Shipping | Lead Time | Trial | Returns | Warranty |
| Heirloom Classic Medium Firm | Freight delivery in the U.S. | ~7–9 weeks | No standardized in-home trial (varies by retailer policy) | Policies are typically more restrictive than bed-in-a-box returns | 15 years |
| Heirloom Classic Firm | Freight delivery in the U.S. | ~7–9 weeks | No standardized in-home trial (varies by retailer policy) | Policies are typically more restrictive than bed-in-a-box returns | 15 years |
Because this mattress is built-to-order and ships via freight, it’s worth reading the shipping, return, and warranty terms before you place an order. Plan on a longer timeline than quick-ship online beds, and treat the purchase more like a long-term home item than a short trial.
FAQs
1. Is the Heirloom Classic really flippable?
Yes. It’s a two-sided tight-top mattress, so you can flip and rotate it to spread wear more evenly over time.
2. What’s the difference between the Medium Firm and Firm options?
They share the same core construction, but the surface feel is tuned differently. Medium Firm has a touch more cushion and is easier to live with across positions, while Firm stays flatter and more resistant—especially noticeable for back and stomach sleeping.
3. Does it feel like a traditional innerspring?
Very much so. You’ll notice bounce, easier movement, and a more “on top” sleep position compared with many foam mattresses.
4. Is it a good pick for side sleepers?
It depends. Many combination sleepers do fine on the Medium Firm option, but strict side sleepers—especially lighter ones—may want a mattress with deeper pressure relief at the shoulders and hips.
5. How does it handle heat?
Both options slept relatively cool in our testing. The innerspring core allows more airflow than foam-heavy designs, and neither feel has the deep sink that tends to trap heat.
6. How strong is motion isolation for couples?
It’s better than many older-style innersprings, but you’ll still notice more movement than you would on many pocketed-coil hybrids. If you like a bit of bounce and don’t wake easily, it should be workable.
7. Is edge support actually solid?
Yes. The perimeter felt stable when sitting and when sleeping near the edge, which helps couples use more of the surface without feeling like they’re sliding off.
8. How long should a mattress like this last?
A flippable build can help extend usable life because you can distribute wear across both sides. As with any mattress, longevity depends on body weight, use, and how consistently you rotate and flip it.
9. Does it work with adjustable bases?
Compatibility depends on size. If you plan to use an adjustable base, confirm options for the size you’re buying before you order.
10. Who is this mattress not a great match for?
Shoppers who want a plush, deep-cradle feel or who need maximum pressure relief for side sleeping will likely be happier with a softer hybrid or foam-forward design.
