Mellow comes up often when shoppers want a straightforward, budget-friendly mattress that still feels comfortable night after night. To make the decision easier, we tested four well-known models—two all-foam options and two hybrids—and compared them using the same scoring system we apply across our reviews.
We ran each mattress through multi-position sleep testing, partner-movement checks, and temperature observations with testers of different body types. That mix helps highlight where a mattress feels supportive, where it compresses too easily, and how it behaves once you’ve spent real time on it.
The main choice is feel: the plush, slower-responding foam of Marshmallow and OLAF versus the springier, coil-supported profile of LAGOM and EIRA. Below is the distilled version of what each model does best, plus the tradeoffs that matter at this price.
Table of Contents
Product Overview
| Mattress | Pros | Cons | Ideal For | Price (Queen, approx.) | Overall Score |
| Marshmallow Memory Foam Mattress | Plush contouring and pressure relief; excellent motion isolation | Edges compress easily; limited support for heavier back/stomach sleepers; can sleep warm | Light to average-weight side sleepers who like a plush, slow-foam feel | Varies by size and retailer | 4.2 / 5 |
| LAGOM Hybrid with Foam Encasing Pocket Spring | Balanced support, stable edges, and a more breathable feel | Too bouncy for strict foam lovers; not an ultra-plush top | Back sleepers and mixed positions sleepers who want an all-around hybrid | Varies by size and retailer | 4.5 / 5 |
| OLAF Gel Snowcloud Top Memory Foam | Cooling cover plus gel foam for a smoother, cooler contour | Edges feel softer; extremely hot sleepers may still want more airflow | Hot sleepers who still prefer all-foam pressure relief | Varies by size and retailer | 4.4 / 5 |
| EIRA Pillow Top Hybrid with Gel Infusion | Medium-firm support with a pillow-top finish and a responsive coil base | Firm feel for light side sleepers; occasional coil noise when shifting | Back and stomach sleepers; supportive option for couples | Varies by size and retailer | 4.3 / 5 |
Testing Team Takeaways
Across the lineup, we felt a clean divide: Marshmallow and OLAF lean into a softer, more “hugging” foam feel, while LAGOM and EIRA add bounce and structure from pocketed coils.
Heavier and heat-sensitive testers preferred the hybrids overall, especially for keeping hips from sinking and for maintaining a steadier surface near the edges.
In partner testing, the all-foam beds did the best job muting movement, but the hybrids were easier to reposition on—less of that slow, stuck-in-foam sensation.
OLAF was the most comfortable foam option for warmer sleepers thanks to its cooling cover, while LAGOM stood out as the most balanced choice when we looked at the full scorecard.
If you have recurring back tension, the more supportive builds (LAGOM and EIRA) generally held alignment better than the plush foam models, especially for back and stomach sleeping.

What We Tested and How We Tested It
We tested four models that represent the main feel profiles in Mellow’s lineup: plush all-foam beds and coil-based hybrids.
We scored each mattress for support, pressure relief, cooling, motion isolation, edge support, responsiveness, durability, using the same rubrics across every test run.
We rotated each mattress onto standard queen bed frames and kept the room environment as consistent as possible. Over repeated nights, we logged pressure points, ease of movement, edge stability, partner disturbance, and heat build-up.

Mellow Mattress: Our Testing Experience
Marshmallow Memory Foam Mattress
Our Testing Experience
Marshmallow arrives with a thick, quilted pillow-top that compresses quickly under your palm. Once the foams warm up, the surface lets shoulders and hips settle in and rebounds slowly when you roll.
As a side sleeper, I felt the best payoff at the shoulder: the top gives enough to reduce pressure, then holds you in place. The tradeoff is stability—sleeping or sitting near the edge feels less secure—and heavier back or stomach sleepers can sink through the comfort layers.
If you’re light to average-weight and mostly sleep on your side (or want a cozy bed for lounging), Marshmallow is the softest and most motion-dampening option here. If you run hot or need firmer, flatter support, the hybrids are a better match.
Pros & Cons
| Pros | Cons |
| Plush pressure relief for side sleeping | Not supportive enough for heavier back or stomach sleepers |
| Very good motion isolation | Edges compress when you sit |

LAGOM Hybrid with Foam Encasing Pocket Spring
Our Testing Experience
LAGOM feels more structured the moment you sit down. You get a modest initial cushion from the foams, then quick pushback from the pocketed coils that keeps you more on top of the bed.
In night testing, it handled position changes cleanly. When I moved from side to back, it kept hips from dropping while still allowing some shoulder give. The foam-encased perimeter also felt steadier when sitting or sleeping close to the edge.
This was the easiest model to recommend across mixed sleepers and couples who want bounce without an overly springy feel. If you’re shopping specifically for a deep, slow memory-foam hug, LAGOM can feel too responsive.
Pros & Cons
| Pros | Cons |
| Balanced medium feel for most sleepers | Not for ultra-plush fans |
| Sturdier support under hips than the all-foam beds | More movement carries across than all-foam |
| Better airflow from the coil core | May creak under hard edge loads |
| Foam-encased perimeter feels steadier | Feel changes mainly by height |

OLAF Gel Snowcloud Top Memory Foam
Our Testing Experience
OLAF’s cooling cover feels noticeably cooler to the touch at the start of the night, and the Snowcloud top adds cushion without making the surface feel overly puffy.
On the bed, the foam compresses smoothly and stays calm when a partner moves—similar to Marshmallow—but with a cleaner, less heat-trapping feel. Very hot sleepers may still prefer a hybrid, but among these all-foam options, OLAF managed temperature best in our tests.
If you like memory foam but want a cooler surface and slightly more support than Marshmallow, OLAF is the better fit. Edge support is still softer than the hybrids, so it’s not ideal if you rely on the perimeter.
Pros & Cons
| Pros | Cons |
| Cooling cover helps shed heat | Still not as airy as the hybrids |
| Smooth contouring for pressure relief | Edges are softer under load |
| Quiets partner motion | Less bounce for fast movers |
| Refined, flat Snowcloud top | Limited firmness choices |

- Type: All-foam memory foam mattress with a quilted Snowcloud top
- Available heights: 10", 12", 14" (we tested 12")
- Made in USA (as listed by the brand)
- Firmness (our feel): Medium

EIRA Pillow Top Hybrid with Gel Infusion
Our Testing Experience
EIRA has the most traditional look of the group: a quilted pillow-top over a coil core. Under hand, it feels firmer than the all-foam beds and responds faster when you shift positions.
Sleeping on my back, it held my hips up and kept my spine flatter than Marshmallow, with moderate contour at the shoulders. The coil base adds bounce for easier movement, though it doesn’t mute vibration as completely as the foam models.
EIRA is the best fit here for back and stomach sleepers who want a firmer, supportive hybrid with a touch of cushioning. If you’re a lighter side sleeper who needs deep shoulder sink, it can feel too taut through the top.
Pros & Cons
| Pros | Cons |
| Supportive medium-firm feel | Too firm for very light side sleepers |
| Coils add bounce and airflow | More movement than the foam models |
| Gel + coils help with heat | Occasional coil noise on hard edge sits |
| Height options in the EIRA line | Not an ultra-plush pillow top |
Details
- Type: Hybrid mattress with gel memory foam over pocket springs and a pillow-top finish
- Available heights: 10", 12", 14" in the EIRA line (we tested 12")
- Firmness (our feel): Medium-firm

- Cooling approach: Gel-infused foam with coil airflow
- Edge and handling: Non-slip bottom and side handles
- Movement feel: Responsive hybrid surface (easier to reposition than all-foam)
- Warranty: 10-year manufacturer warranty

On the scorecard, LAGOM is the most balanced option overall. OLAF leads the all-foam choices for cooling, while Marshmallow scores highest for plush pressure relief. EIRA is the firmer, support-forward hybrid—especially for back and stomach sleeping.
Best Picks
-
Best overall hybrid: LAGOM Hybrid with Foam Encasing Pocket Spring
Most balanced scorecard—supportive under the hips, steadier along the edge, and easier to reposition on than the all-foam models. If you’re specifically shopping for a Pocket Spring mattress feel, LAGOM is the safest pick in this group. -
Best cooling all-foam: OLAF Gel Snowcloud Top Memory Foam
The cooling cover and gel foam reduced heat buildup without giving up the slow-foam contour many hot sleepers still prefer. -
Best plush foam for side sleeping: Marshmallow Memory Foam Mattress
Soft quilting and deep contouring helped side sleepers, especially if you deal with shoulder pressure.
How to Choose the Mellow Mattress?
Start with sleep position and how much structure you need under the hips. If you share a bed, prioritize motion control and edge stability—especially for couples.
Marshmallow is the softest pick. For light-weight side sleepers, it allows more sink at the shoulders and hips, which can make the surface feel noticeably gentler.
If you’re mainly a back sleeper, LAGOM is the most balanced hybrid in this set—supportive without feeling hard.
If you’re a hot sleeper but still want memory-foam contouring, OLAF is the cooler all-foam option we tested.
For a heavier couple, the hybrids (LAGOM and EIRA) are the safer choices for support and easier movement. Choose LAGOM for a more even feel; choose EIRA if you want a firmer top.

Limitations
Overall, these models work best for light to moderately heavy sleepers who like a medium to plush feel. The foam beds emphasize contour and quietness, while the hybrids emphasize support and easier movement.
If you want an ultra-firm, almost board-flat surface, this lineup won’t feel rigid enough. Pricing is budget-friendly, but the lowest-priced beds on the market often undercut it with bigger tradeoffs in edge stability, cooling, or long-term support.
