  • Nice Mattress
Style: 14 Inch Size: King
Nice and firm. Not to soft. Mattress is big and tall not little at all. Love it!

  • Edge support
I originally bought this mattress for my son but I bought a king by mistake instead of a queen...so I replaced my mattress instead. I'm about 350lbs, my hubby is about 200lbs, and our daughter is about 60lbs (has her own room and nice bed but always climbs in with us, we are forced to the edges lol) and we all sleep very comfortably on this mattress. The edge support is phenomenol!! We don't disturbed each other and no rolling into each other either. It's a little firmer than we were used to (had a memory foam split king but got tired of the split). It's well made, we can even still use our adjustable frame with it without issues. I'd recommend this mattress to anyone. ... show more

  • Affordable Excellence
Perfect for heavier couples. Soft but supportive. Does not feel like a memory foam mattress. Feels great front, back or side sleepers. Will definitely buy this mattress again if needed!

  • Love at first night
Style: 12 Inch Medium Size: Queen
This mattress sleeps well and is very comfortable. Firmness is somewhat subjective. I prefer firm and this is plenty firm for me. Not mushy at all. Fairly solid when placed on solid frame. A slight bounce to it but that is fine. I do not expect this to last 10 years at this price but will be more than happy with 5. Not our primary mattress so excellent choice for secondary use. I suspect it will be more than adequate for most people’s primary use also. ... show more

  • Great buy!
Style: 12 Inch Medium Size: Queen
I shopped around at mattress stores, but I just couldn’t bring myself to spend $1000 on a mattress. So I found this one on Amazon I had an actually lower price. I was a little hesitant at first because of how inexpensive it was, however, when we got it put it on the bed and went to bed at night I had the best sleep I’ve had in a long time. What a fantastic mattresses, very comfortable and everything they said it was It was more. I highly recommend this one ... show more

  • So comfortable!!
I have had such a problem trying to find the right bed for my back and hips. This is the one. It’s soft but still firm and it doesn’t put pressure on my hips when I sleep. I’m a side sleeper and I used to wake up with sore hips all the time. I don’t anymore because this mattress has the perfect combination of softness and firmness. I would buy it again!! ... show more

  • Do not purchase
Style: 12 Inch Medium Size: Queen
I had very high expectations from this mattress considering all these reviews. However this is going to be my honest experience. I let the mattress sit undisturbed for 3 days so it can fully take its shape. The middle of the bed feels nice and medium firm as stated by the manufacturer. Thats where the positive experience ends. The corner and edges of the bed did not fully "inflate". It's super soft and practically collapse on it self. The description says it's corners are strong which is a lie in my case. One side of my bed is higher than the other because it did not fully take its form. I rotated my mattress to see if the problem would resolve however it persisted. This is one of the items you really can't return because how are you supposed to put it back in the box once it's fully inflated. I would not recommend this product on the grounds that it's not true to its description and you will be out of your money with well bellow average product. ... show more
