  • The arrival boxed mattress is a killer but the mattress is marvelous
Style: Hybrid Medium 12" Size: Queen
This weighed 300+ pounds in its box so I feel you would need help dealing with this. Once unwrapped it exploded into a full size mattress. Easier to deal with. I broke my back and had to do something about my old mattress. At under $400 dollars I felt I could not go too wrong. It has been wonderful. The support is there and I wake with so much less pain. I am so very pleased. I put it on top of my old box springs only so I could keep my high bed. So very pleased ... show more

  • Sweet Dreams
Style: Hybrid Medium 12" Size: Queen
Frustrated by the fluff of mattress store sales tactics, so I looked at AMZ & found this dream mattress!! Goldilocks approved... #justright Order & delivery were a cinch - UPS driver did the heavy lifting. Mattress is packaged well in a tiny box. Make sure you have plenty of space for opening the box & removing the packaging!! Air out for 2-3 days, cover with normal bedding, and enjoy your first good night's sleep. You won't want to leave the bed! 12" is the perfect size & the hybrid construction offers unbelievable comfort. Regular-queen linens fit perfectly. Mattress-in-a-Box is a strange concept till you realize how much sense it makes. Cut out the 'middle-man' and order directly from AMZ Prime. Serta is a classic brand for a reason - hi-quality product for a fair price & years of construction experience. ... show more

  • Good Budget buy
Style: Hybrid Firm 11" Size: Full
I ordered this Monday afternoon and it was delivered yesterday afternoon. The mattress started to inflate before I even finished taking the shrink wrap off! Less than 10 minutes later the mattress was at 12 inches but I am leaving it to "breathe" for another day. I did do a quick test lay and it was perfect not to soft and not too firm. I'll update after some time. ... show more

  • Comfortable mattress
Style: Memory Foam Firm 12" Size: Queen
Very comfortable. Arrived quickly, works well with our adjustable bed. I have had many back surgeries. This mattress really is comfortable for me.

  • Just unpacked first impression and nap
Style: Hybrid Firm 11" Size: Twin
Delivery service beat up box, BAD. WHOLE BOTTOM was ripped off and taped back on, in scary fashion. Was shocked that insides were intact, and vacuum seal held. Unpacked in place atop box spring. Inflates very quickly and well, no seams or dents or misshapen areas. No smells or off gassing detected, ZERO. Made bed and took a nap only a few hours later. Was exactly as described WRT firmness. This is, so far, a great buy for money. WILL update this after a month or so. ANY mattress change is likely to result in 1 to 2 weeks of soreness as your body gets used to it, so i am prepared for that, but so far ZERO complaints on feel or build quality. ... show more

  • If you want an inexpensive, soft mattress, this would be great.
Style: Hybrid Firm 11" Size: King
This was much softer than I expected, and within just a few weeks of use, the edges started to collapse (neither my husband or I is particularly large or heavy, either).

  • Not firm
Style: Memory Foam Firm 12" Size: Queen
I ordered a firm mattress but it’s not firm at all. Your body sinks on the corners. One side sinks more than the other. I bought sturdier memory foam before. If you like softer beds then get it but it is not “firm” at all

  • Love it
Style: Hybrid Firm 11" Size: Queen
After having a crappy mattress for a year and a half, I'm glad we picked this one. It's good quality. I'm a hairstylist that stands all day and deals with back pain. This helps so much. The 10 year warranty helps too, so I know I'm not getting another piece of crap.
