by The Simmons 8" Memory Foam is a budget all-foam mattress sold through Walmart and similar retailers. At $269 to $399 depending on size, it offers medium firmness (6.5/10), CertiPUR-US certified foam, and a 100-night trial. It works for lightweight back and combo sleepers but bottoms out under heavier body weight and runs warm. If you want a durable memory foam mattress with a real warranty, Saatva's Loom & Leaf is the premium step-up we recommend.
Saatva Loom & Leaf
9.2/10
- 5 lb high-density memory foam, far denser than budget options
- Cooling gel panel across the center third plus organic cotton cover
- Free white-glove delivery, in-room setup, and old-mattress removal
- 365-night home trial and lifetime warranty
- Substantially more expensive than the Simmons
- Does not compress for box shipping, requires white-glove scheduling
The Loom & Leaf is the all-foam Saatva mattress built for people who want memory foam body-contouring without the heat retention and durability problems of thin budget foam. At 12 inches with a 5 lb core, it outlasts entry-level foam by a wide margin.
Simmons 8" Memory Foam: who is it for
The Simmons 8" Memory Foam is a Walmart-channel mattress aimed squarely at the budget end of the market. At under $400 for a queen, it competes with Zinus and Lucid rather than Casper or Nectar. The three-layer foam stack includes a gel memory foam comfort layer, a motion isolation middle layer, and a high-density polyfoam support base. The mattress arrives compressed in a box, ships free via FedEx, and carries a 100-night trial plus a 10-year limited warranty.
It is a decent option for guest rooms, children's beds, bunk beds, and anyone under 150 lbs who wants the memory foam feel without spending more than $350. Outside those use cases, the thin profile and budget foam density create real problems.
Construction
The Simmons 8" sits across three distinct foam layers:
- Gel memory foam comfort layer (approx. 2 inches): The gel beads reduce surface temperature somewhat, but the thin layer means sleepers over 160 lbs will compress through it quickly.
- Motion isolation layer (approx. 2 inches): A transition foam layer separates motion between sleep partners. At this thickness, it does the job for lighter couples.
- High-density polyfoam base (approx. 4 inches): The support core gives the mattress its shape. A 4-inch base is functional for children and lightweight adults; heavier sleepers will notice a "bottoming out" sensation within the first weeks.
CertiPUR-US certification covers all three layers, confirming no harmful off-gassing chemicals. Made in the USA.
Comfort and firmness
The Simmons 8" lands at medium firmness, roughly 6.5 out of 10. Back sleepers and combo sleepers in the 120 to 200 lb range will find it comfortable. The foam conforms adequately to the lumbar curve for lighter-weight back sleepers, and the responsiveness is good enough for position changes.
Side sleepers generally find the mattress too firm through the hips and shoulders because the comfort layer does not have enough depth for real pressure relief in a hip-loaded position. Stomach sleepers under 150 lbs may find it workable; anyone heavier will notice lumbar extension.
Performance
Back pain
The foam layers distribute weight evenly and provide basic lumbar support for lightweight back sleepers. The medium firmness keeps the spine reasonably neutral. That said, it is not a back-pain therapeutic mattress, and anyone with chronic pain will likely need more targeted support and a deeper comfort layer.
Edge support
Edge support is minimal. All-foam mattresses at this price point tend to compress significantly at the perimeter. Sitting on the edge or sleeping close to the edge will produce noticeable roll-off.
Motion isolation
The dedicated motion-separating layer does reduce partner disturbance. For couples where both partners are lightweight, it is a genuine strength of the build.
Cooling
The gel memory foam layer helps marginally, but the closed-cell foam construction retains heat. Hot sleepers should look elsewhere. The mattress is not suitable for anyone who regularly sleeps warm.
Durability
The primary durability concern is foam density. Budget memory foam in the 2.5 to 3 lb range, which is typical at this price point, compresses and loses resilience within 3 to 5 years for average-weight sleepers. The 10-year warranty covers manufacturing defects, not gradual body impressions below a certain depth. For a primary bed used nightly by adults, longevity is a real limitation.
Who should buy the Simmons 8" Memory Foam
- Lightweight sleepers (under 150 lbs) who want a basic memory foam feel
- Guest rooms with light, infrequent use
- Children's beds and bunk beds where profile height is limited
- Anyone needing a temporary or transitional mattress on a tight budget
Who should look elsewhere
- Sleepers over 200 lbs who will bottom out through the base
- Hot sleepers who need active cooling or latex airflow
- Side sleepers who need at least 3 inches of pressure-relieving comfort foam
- Anyone who needs this mattress to last more than 5 years under daily adult use

Verdict
The Simmons 8" Memory Foam is a functional budget mattress for lightweight sleepers and low-use situations. The CertiPUR-US certification, 100-night trial, and made-in-USA build are genuine positives at this price. The limitations are real: thin comfort layer, limited edge support, moderate heat retention, and durability that does not hold up under daily adult use for more than a few years.
If you are shopping in this price range, it is a reasonable purchase for the right use case. If you are shopping for your primary mattress and memory foam is the priority, the step-up to a denser, better-built option is worth considering.
The Simmons 8" Memory Foam is a budget pick worth considering for guest rooms, kids' beds, and lightweight sleepers. For a daily-use memory foam mattress with real longevity, the Saatva Loom & Leaf is our tested recommendation, with 5 lb high-density foam, a 365-night trial, and a lifetime warranty.
Frequently asked questions
Is the Simmons 8" Memory Foam good for back pain?
For lightweight back sleepers, the medium firmness provides reasonable spinal alignment. It is not a therapeutic back-pain mattress. Sleepers with chronic pain or significant weight will want a mattress with a deeper, zoned comfort layer.
Does the Simmons mattress sleep hot?
The gel memory foam layer helps slightly, but the closed-cell foam construction retains heat. It is not ideal for hot sleepers.
How long does the Simmons 8" mattress last?
Realistically 3 to 5 years under daily adult use, depending on body weight and usage frequency. The 10-year warranty covers defects but not normal gradual compression.
Is the Simmons 8" Memory Foam flippable?
No. It is a one-sided mattress. Rotate it 180 degrees every 4 to 6 months to slow uneven wear.
Does it work with an adjustable base?
Yes, the all-foam construction makes it compatible with most adjustable bases.
