    • Very satisfied, excellent for my 5-year-old son

Review Image by Es súper bueno Es súper bueno
I am extremely happy with this mattress! The 5-inch gel memory foam provides the perfect balance of softness and support. It feels medium-firm, which is exactly what I needed for a comfortable night’s sleep. The cooling effect really works—I no longer wake up feeling hot, and the pressure relief makes a huge difference for my back and shoulders. The mattress arrived quickly, well-packaged, and expanded to its full shape within a few hours. The quality is impressive, and I love that it’s CertiPUR-US certified, giving me peace of mind about safety and durability. For the price, you honestly can’t beat it. It’s lightweight, easy to set up, and fits perfectly on my bed frame. If you’re looking for a comfortable, affordable, and reliable mattress, I highly recommend this one! ... show more

    • Yes!!
Color: White Size: Twin Style: 8 IN
I am genuinely shocked by the quality of this 8-inch thick twin memory foam mattress, especially given the price. I went into this purchase with low expectations, assuming it would be just a temporary solution, but it has completely exceeded them. The mattress expanded to its full size quickly and has a perfect medium-firm feel. It provides excellent support and conforms to my body, relieving pressure points and making for a comfortable and restful night's sleep. It's an absolute steal for anyone on a budget who doesn't want to compromise on comfort. This mattress is a prime example of getting far more than you pay for. ... show more

    • An absolute steal

If you’re having doubts on whether this is the mattress or not, let this review help you. I got the 10 inch queen mattress and i am so impressed. Immediately after rolling it out it got to the ten inches and it is so comfy. Such a great buy and would recommend it to anyone looking for an affordable mattress. It had no smell at all ( i saw some reviews saying it had a bad smell) it feels like those really nice mattresses that would make those commercials with kids bouncing on the bed and a glass of wine staying still right next to it. Firmness is exactly as advertised. My mattress before this one was 700 dollars and this one feels nicer. Pictured is my cat who also loves and vouches for this mattress. (My bed frame is coming tomorrow, lookout for that review as well) ... show more

    • So Far, So Good
Color: White Size: Queen Style: 10 IN
Definitely firm but still very comfortable. You will definitely sink down quite a bit if sitting upright for a while, but it returns pretty quick. Inflated very quick upon unboxing, dimensions fairly accurate to size ordered. So far only gripes I have about it is it seems to hold heat a lot? Not entirely sure because it is Summer but compared to my last mattress it gets a bit uncomfortable with my heat. That and the cover thing that comes with it, while it is a nice feature my cat's claws constantly get stuck in it and the fibers seem to pull out easily. Lot of loose fiber nubs sticking out already in the month or so of use. The main reason I like this mattress though is it's all foam, one of the only affordable ones I've seen where 95% of the thing isn't crappy coil springs that wear out quickly. While most of it is "support foam," it's still nice being so thick with actual cushion. I would recommend specifically the 10" size as it seems the rate of actual memory foam they offer per size doesn't increase much, less value in it. A bit weird of a policy since you'd be paying more.. would expect some more quality foam. Suppose it's due to width increasing making increased memory foam being more spread out. Overall pretty good bed, would recommend. ... show more

    • Nice mattress!
Color: White Size: Twin Style: 8 IN
This mattress is very comfortable. I bought it for my granddaughter as she transitioned to a bigger bed. She sleeps so well on it. It has great support and conforms to you. It was delivered fast and easy to unbox. It was very good price as well. Well worth the buy.

Definitely worth the price. I bought two of the 5-inch mattresses for a new daybed in our spare bedroom, and they worked out perfectly. My mom slept on them during her visit and mentioned they were surprisingly comfortable, firm and supportive. For the price, I wasn’t expecting much, but they exceeded my expectations. If you’re on the fence, don’t hesitate these are a great buy for guest rooms or daybeds! ... show more

    • Very firm
Color: White Size: Queen Style: 10 IN
Got the 10" for a murphy bed. We like a firm mattress, but this thing is HARD firm! If that's what you're looking for, it's great. If not, move along. Seems well made, no weird scent upon opening (maybe a light scent but dissipated quickly!). 83yo MIL slept on it and said it was comfortable. She likes it hard. ... show more
