  • Great mattress.
Style: 14" Size: King
This is a really comfortable bed at a very attractive price point. It has good support. I get a great night’s sleep on it. Not hot like my old tempurpedic mattress Pay for the in the room delivery as they take away the old mattress and it was effortless. This is comparable to $1400 mattresses at your local store. ... show more

  • It's a good mattress
Style: 14" Size: Queen
Overall I like this new mattress. We purchased it because it is certified to contain safe materials and it's soft top (foam) mattresses are good for side and back sleepers and the lower coils provide structure to prevent the mattress from sinking. Our mattress sits on a boxspring mattress which sits on a bed frame so the mattress top is almost 3 ft above the ground and the edges roll / sink downward when I first get on the bed and in a sitting position with my legs hanging off. Otherwise, I like this mattress a lot. ... show more

  • Light weight great mattress
Style: 14" Size: King
Comfy and supports different body weights. It fit the bedframe and appears to be a durable product. Time will tell

  • PERFECT!
Style: 12" Size: King
This mattress is awesome. After trying one out in the mattress store and not wanting to pay 1300.00, I found it here. Husband and I are very very picky and was skeptical about a hybrid after having a pillow top for 20 plus years. But we do not regret buying this at all. It’s not super soft, but not too hard. We wake up with NO back or leg pain anymore. I would give 10 stars if I could. ... show more

  • It's ok
Style: 14" Size: King
It's ok. Super plush and you do sink. It's comfortable but I wish we would have purchased a firmer mattress.

  • Comfy
Style: 14" Size: Queen
It's very comfy. A bit on the soft side. Not as comfy as the name brand original memory foam mattress we replaced but great for the price and convenience of having it "in a box". No noticable smell.

  • Bed is magical. Soft but firm reinvented.
Style: 14" Size: Queen
Honestly didn’t think it would be this good. This mattress is amazing. It says it’s super soft but with the springs and the other technology they have in the mattress, it’s truly amazing. It’s soft enough where you feel like you’re on a cloud but a cloud that’s supporting your bodies natural curves and conforms to hold you in a flat plane as natural as can be. I’m truly impressed with how well this bed is. ... show more
