    • Best mattress!
Style: Full Size: 10 Inch
This is one of the most comfortable mattresses I have slept on. Fast delivery, expanded to 7 inches almost immediately and fully expanded to the full 10 inches by the next day! I woke up with no back pain for the first time in a long time!! Highly recommend this mattress! There was no smell that i noticed when it was unboxed. ... show more

    • The best!
Style: King Size: 12 Inch
So I had bought 3 of theses already but in twin size/8inch for my boys. Was kinda nervous to buy my own because of the price & to think it wouldn't be worth it for me because I'm so picky but I was Super happy for ending up picking this 1. So comfortable as well as a memory foam mattress that might cost you over $700. Not as heavy as I thought. Makes my back feel so supported after my long 12hr night shifts. I bough a king size/14 inch, and I was so nervous I might not like it because the price seemed low. But after sleeping on it my first night I knew it was going to be worth ever penny. It doesn't make any noises. And is so sturdy I don't even think I will need to replace it in over 10yrs. It sounds exaggerated but I'm not. I'm so happy with my purchase. ... show more

    • Best mattress ever
Style: Queen Size: 10 Inch
I wanted to wait a few months before rating this mattress to see how it does over time, and 6 months in I can honestly say this is the most comfortable mattress I have ever slept on. A perfect mix of firm support and comfortable softness. I have bought mattresses for well over a thousands dollars, and this beats them all. ... show more

    • Comfortable and washable
Style: Twin Size: 8 Inch
Height works well for a toddler, but I’d recommend getting a taller one for anyone bigger for more comfort. Great value for the money and washes out stains easily.

    • DO NOT BUY THIS MATTRESS!
Style: Twin Size: 12 Inch
LUMPY! Haven’t had this a year and am looking for another mattress soon. I’ve put a board underneath, a 2 inch memory foam topper and a regular mattress pad on this mattress and still sags where my bottom is and one side of mattress is higher when I’m on it. Have turned mattress every 2 weeks (since you can’t flip it) and does not help. Waste of money! ... show more

    • Great matress for the price!!!
Style: Full Size: 14 Inch
I was very skeptical about: 1. Buying a matress on the internet (especially since it was such a low price) 2. Buying a matress without any reviews (for some reason, all the reviews were for bed frame) This matress was the buy of the century!!!!! It is supportive, but not hard as a rock. (It isn't all too "squishy" either. Just like Goldilocks....it was just right!) I can't sing enough praises of this purchase. We opened it about 5pm and slept on it that night. There was no strong chemical odor and it puffed up pretty quick. It did take a day or 2 to get to its full, expanded potential, but it wasn't all too noticeable within those first 2 days. If you are in the fence about pressing the "buy" button....just like Nike....DO IT! (you won't regret it!) ... show more

    • Just right
Style: Full Size: 12 Inch
We’ve bought 2 now, had one for nearly a year and decided to buy another to replace our other child’s bed. Just the right firmness for us, granted all of us that sleep on them are quite light, but they are soft enough to be comfortable but not so soft that you sink in and get eaten up. We also love that there’s no fiberglass in them as that can be a common fire proofing material ... show more

    • Pretty Good, but thinner than advertised
Style: Full Size: 6 Inch
This foam mattress is pretty good, but it is advertised as 6" thick and it is about an inch shy of that. Otherwise I would have given it 4 or 5 stars.
