    • Great mattress
Size: Twin Style: 6-inch Pattern Name: Plush-Feel
This one is SO soft and perfect for my lightweight toddler to still be about to sink in a little and get comfortable. Fluffed up fully in a couple days, as expected.

    • Great buy!
Size: Twin Style: 6-inch Pattern Name: Plush-Feel
This bed was perfect and comfortable for my daughter’s trundle bed. We have this bed in 6in and in 8in both are wonderful to sleep on. I would highly recommend, especially considering the price!

Review Image by Wilde
I’m quite satisfied with this mattress. Full disclosure to others looking to this review for guidance on whether or not to buy it: I had ordered another, cheaper memory foam bed in a box compressed mattress and it was just way too firm. It was too expensive to send it back, so I have it underneath THIS mattress. I also have a memory foam mattress topper on top. So this mattress is sandwiched between a firm memory foam mattress and a soft memory foam mattress topper. I actually had two mattress toppers on because I just happened to have two, but it was way too high and just too mushy. Anyway, I digress. I really like this mattress. I like a very soft mattress but sometimes too soft seems to hurt my lower back and my joints, specifically my hips. I’ve had no issues with pain anywhere. I sleep well on this mattress. I don’t know what it’s like on its own but I know that the way I have it set up is excellent. I also know that it was super easy to set up. I dragged the box up one flight of steps by myself. I cut it open and place it on the bed on my own. It was a little difficult but I managed and it didn’t take long. It’s amazing how quickly it puffs up into a mattress. Truly amazing. I feel like I’ll have this mattress for a long time. It seems very well made / durable. I think it was worth the money. I’m happy! If you like a plush mattress and an easy and quick bed in a box, order this. ... show more

    • Comfortable Budget Mattress — Soft, Supportive, and Good Value for the Price
Size: Twin Style: 10-inch Pattern Name: Plush-Feel
The Amazon Basics 10" Memory Foam Mattress is a solid choice if you’re looking for an affordable, comfortable mattress without paying premium brand prices. It’s especially good for guest rooms, kids’ rooms, or anyone who prefers a softer sleep surface. Right out of the box, the mattress expanded pretty quickly after opening (give it the recommended time before sleeping on it). There was a mild “new foam” smell at first, but it faded within a day or two, which is pretty typical for memory foam mattresses. The feel is definitely on the softer/plush side. If you like that slightly sinking, contouring memory foam feel, this does a good job. It cushions pressure points well, especially for side sleepers. It still has enough support underneath that you don’t feel like you’re completely sinking through the mattress. Temperature-wise, it sleeps fairly neutral for memory foam. It’s not specifically marketed as cooling, but I didn’t find it overly hot compared to older memory foam styles. The cover looks clean and simple, and the white/grey design works well with most bedding setups. Pros: ✔ Very comfortable plush/soft feel ✔ Good pressure relief (great for side sleepers) ✔ Good value for a memory foam mattress ✔ Expanded quickly after opening ✔ Minimal off-gassing smell compared to some foam mattresses Cons: ✖ May be too soft for stomach sleepers or people wanting very firm support ✖ Not specifically a cooling mattress (just average temp control) ✖ Edge support is decent but not super firm Overall: If you want a budget-friendly memory foam mattress that still feels comfortable and supportive, this is a great option. It’s especially good for guest rooms, kids, teens, or anyone who prefers a softer sleep surface without spending a lot. ... show more

    • Soft and comfy
Size: Twin Style: 8-inch Pattern Name: Plush-Feel
Super soft - these are the BEST! They (I bought two sets) took a while to get here, but so worth the wait. I would definitely buy again!

    • Great value
Size: King Style: 12-inch Pattern Name: Plush-Feel
Fantastic value! Expanded properly, initial smell wasn’t too bad and very comfortable. Plush is more like medium but it’s a very supportive and comfy medium feel. Time will tell how great this mattress holds up, but so far so good. Sure beats getting ripped off at a furniture store.

    • Perfect!!!

Amazing and soft, everyone that tries it, loves it!!!!! It’s just right, it’s soft but not too soft.

    • Not breathable very very soft
Size: Queen Style: 10-inch Pattern Name: Plush-Feel
A very sweaty experience.. get cooling cover to let air flow. Not as firm as hoped. I had to buy an extra support system to keep from feeling rungs on bed frame. Sinks in too far down. It's probably ok if you like a very soft bed, if you have a box spring for ventilation and support.
