Finding a mattress that does not wreck your back or your wallet feels like a lost cause. The cheap foam mattress market is full of options that look good online but sag within six months. This guide cuts past the guesswork by stacking the four strongest contenders side by side — covering exactly what the firmness feels like, how much cooling they actually deliver, and which ones pass the long-haul durability test.
I’m Mohammad Maruf — the founder and writer behind WellFizz. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
The goal is to help you pick a cheap foam mattress that genuinely supports your sleep without forcing you to choose between comfort and cost.
Our Picks at a Glance
How To Choose The Best Cheap Foam Mattress
The core decision in a foam mattress is balancing thickness, firmness, and cooling. Thicker does not always mean better — it depends on your weight and sleeping position. A 12-inch mattress can feel plush but may sink too much for heavier sleepers, while an 8-inch mattress might be too firm for side sleepers who need pressure relief at the hips.
Firmness and your sleeping position
Medium-firm is the safest place to start. It supports side sleepers around the shoulders and keeps back sleepers from sinking into a banana curve. Stomach sleepers typically need a firmer surface to avoid lower-back strain. Most cheap foam mattresses sit at a medium or medium-firm feel, so check the exact description rather than assuming.
Cooling features matter more than you think
Memory foam traps heat by design — it softens as it warms to your body. Gel-infused layers and breathable covers (like knitted polyester or cool-touch nylon) help pull that heat away. If you wake up sweaty, look for a mattress that explicitly mentions cooling gel or airflow channels in the spec list.
Certifications mean real safety
CertiPUR-US is the meaningful standard here. It verifies the foam is free from heavy metals, formaldehyde, and ozone depleters, and it keeps VOC emissions low. OEKO-TEX certification on the cover adds another layer of skin-friendliness. A mattress missing both is a pass in this category.

In‑Depth Reviews
1. Novilla Queen Size Mattress, 10 Inch Memory Foam
The 10-inch crowd-pleaser that balances pressure relief with a price that does not sting.
The thing owners talk about most is comfort — over 200 people call it out — and specifically the way the gel-infused memory foam creates a medium-firm feel that relieves hips and shoulders without making you feel swallowed. The real test is waking up without stiffness, and buyers report that this mattress helps with hip and back pain after a full night’s rest. The knitted cover and cooling gel layer are designed to keep air moving, which matters if you tend to overheat in the night.
Motion isolation is a standout here. The high-density foam layers absorb movement well, so if your partner tosses, you stay still. The edge support is decent but not the strongest in this lineup — you will feel the perimeter give a bit when you sit or sleep right on the edge. One reviewer noted that after the full 72-hour expansion period, the mattress measured 9.5 inches rather than the advertised 10 inches. That is a small difference in height, but it is worth knowing if you expect an exact 10-inch profile.
cloud-like pressure relief
- Comfort is the most-praised feature — over 200 owners highlight it, with firmness close behind at 141 mentions.
- Excellent motion isolation for couples or light sleepers; the high-density foam absorbs partner movement.
- A CertiPUR-US certification plus a 10-year warranty and a 100-night trial period back the purchase.
edge support could be firmer
- A few units do not reach the full 10-inch height after expansion — expect about 9.5 inches in some cases.
- Edge support is functional but not rock-solid; sitting near the edge causes some compression.
value memory foam: you need a comfortable, motion-isolating mattress at a value price and sleep in a standard bed frame or platform base.
for strict back sleepers: you want a true 10-inch profile or plan to sit on the edge frequently — the depth variance and edge support may bother you.
2. L’Baiet 8 Inch Gel Memory Foam Mattress, Queen
An 8-inch mattress that feels soft and supportive — and owners cannot stop calling it a bargain.
At 8 inches thick, this mattress stands out as a low-profile option that still delivers a medium feel. The three-layer build uses cooling gel-infused memory foam on top, transition foam in the middle, and a support base underneath. Owners describe it as very soft and comfy — one buyer mentioned leaving it on a smooth surface for 72 hours before using it and then finding it both soft and comfortable. The polycotton cover is OEKO-TEX certified and hypoallergenic, which means fewer worries about odours or irritation for sensitive sleepers.
Where this one shines is ease of use — especially for kids’ rooms, bunk beds, or guest setups. Owners mention that even a 70-year-old handled the twin-size version alone. The lack of off-gassing is a consistent point: multiple owners mention there is no strong chemical smell when unboxing. Compared to the Novilla 10-inch, the L’Baiet is 2 inches thinner, so it sits noticeably lower on a frame. That works well for low-profile platforms or daybeds but may feel too shallow for heavier adults who want more cushion.
cooling gel layer
- Comfort leads the feedback — 64 owners praise it — and the mattress is described as soft yet supportive.
- No notable off-gassing smell, plus CertiPUR-US foam and an OEKO-TEX cover for safety.
- Very easy to handle alone thanks to its lighter weight and compact packaging.
initial off-gassing strong
- At 8 inches deep, it is low-profile — side sleepers over 200 lbs may want more thickness for pressure relief.
- Some owners feel it is softer than medium-firm; check your firmness preference carefully.
budget cooling pick: you need a thin, safe, and hypoallergenic mattress for a kid’s room, bunk bed, or daybed where height matters.
if sensitive to odors: you are a heavier side sleeper or want a taller mattress that sits high off the frame.
3. Amazon Basics Medium Firm Memory Foam Mattress, 12 Inch
A 12-inch mattress that runs firm — back sleepers and heavier users will feel the difference.
You get noticeable structure from 3 inches of gel memory foam (a foam that molds to your body while pulling heat away), 2 inches of comfort support foam, and a 7-inch flex comfort base. Owners describe it as near firm — one buyer at 210 lbs noted they sink slightly but still feel solid support where it counts. The firmness gets mixed reactions: some call it “hard as a rock,” while others say “not too soft and not too firm.” The wave-shaped support layer in the middle is designed to create airflow channels, though some owners feel the mattress runs slightly warm despite the cooling layer.
The zippered, removable cover is a practical touch — you can unzip it for cleaning, which is rare at this price tier. The bed-in-a-box setup works well, with owners reporting it reaches a usable firmness within six hours and fully expands within a day and a half. Heavier users get better support from this 12-inch profile compared to the thinner L’Baiet 8-inch model, since the extra foam layers prevent bottoming out under weight. The trade-off is that the firm feel may be too much for pure side sleepers who need more plushness at the shoulders and hips.
thick supportive core
- Strong, stable support for back and stomach sleepers — owners say it is good for spine alignment.
- Removable, washable cover via a zipper — a convenience feature not all budget mattresses offer.
- CertiPUR-US certified foam and an OEKO-TEX certified cover for safety and low emissions.
medium feels firmer
- Firmness splits opinions — some find it ideal, others describe it as uncomfortably hard.
- Cooling is average; heavier or hot sleepers may still feel warmth despite the gel layer.
firm budget option: back and stomach sleepers who prefer a sturdy, near-firm surface and want a cleanable cover.
for plush seekers: you are a dedicated side sleeper or a hot sleeper who needs aggressive cooling features.
4. Novilla Bliss Cooling Queen Size Mattress, 12 Inch Gel-Infused Memory Foam
The cool-touch cover and gel core make this the best pick for anyone who sleeps hot.
Novilla’s Bliss series puts cooling front and center. The cover uses a cool-touch Nylon fabric blended with 30% plant-infused fiber that feels icy to the touch. Inside, the NanoGEL memory foam is engineered to move heat away rather than trap it. Owners confirm the difference — multiple buyers mention they stopped waking up sweaty or dealing with night sweats. It is the standout for hot sleepers in this lineup, especially compared to the Amazon Basics 12-inch, which some find warm despite its gel layer.
The triple-layer foam system (gel foam, cushioning foam, high-density support foam) delivers a medium feel that adapts well to different positions. Customers note excellent support for back and shoulder pain, with the mattress “hugging the body without sinking.” The mattress carries three certifications — CertiPUR-US, OEKO-TEX, and ISPA — so it covers safety from the foam through the fabric. Setup is straightforward, and owners note expansion happens quickly, with minimal to no strong odor. Some side sleepers who prefer a plusher feel may find the medium firmness just right, while stomach sleepers might wish for a touch more rigidity.
dual cooling tech
- Comfort wins over 300 owners — the top-praised aspect — and softness is second at 233 mentions.
- The 2X Cooling Tech with a cool-touch nylon cover genuinely helps hot sleepers stay comfortable.
- Triple-certified (CertiPUR-US, OEKO-TEX, ISPA) for safety, plus a 10-year warranty and 100-night trial.
motion transfer noticeable
- The medium feel works for many but may be too soft for stomach sleepers who need a firmer base.
- Reinforced edges are present, but some owners note they are not as rigid as a hybrid coil edge.
hot sleeper choice: you sleep hot, want reliable pressure relief, and prefer a medium firmness that adapts to your body.
if you share bed: you need a firm stomach-sleeper surface or want the stiffest edge support possible from a foam mattress.
Understanding the Specs
Firmness and your sleeping position
Medium-firm is the broadest comfort target — it supports side sleepers around the shoulders, keeps back sleepers neutral, and provides enough resistance for stomach sleepers. A cheap foam mattress tends to sit at medium or medium-firm, but the actual feel can vary because “medium” is not a regulated standard. Gel-infused models can feel slightly firmer because the gel layer adds density rather than plushness.
Thickness and body weight
An 8-inch mattress works well for kids or lighter adults (under 150 lbs), but heavier sleepers often compress thin foam and hit the base layer, which feels hard. A 10-inch or 12-inch mattress gives more room for the foam to contour without bottoming out. The trade-off is that thicker mattresses trap more heat — which is why the cooling tech in the Novilla Bliss or the Amazon Basics mattress becomes important at the 12-inch level.
