This is an amazing mattress! I slept on it the first night I had it and I was disappointed that it was not very comfortable. But the next night, after it had time to fully re- inflate, it was PERFECT ! It's firm but also soft and so comfortable ! Alot of times you get what you pay for but even though this mattress is on the cheaper side, it's just as good as the really expensive one I just replaced.

Money well spent. Was alittle firm for me but I bought this firm knowing my fiance would love it. I put a mattress pillow on my end snd now we are both happy. Thicker then most mattresses that I had which I absolutely love it sits higher. Worth the money great quality ive had it for 4 months now my fiance is a big man and so far no sagging on his end which we had an issue with before. No funky smell to it.

Comfortable this mattress is between firm and soft. I definitely added a mattress pad because it is a bit on the firmer side but overall for the price it’s pretty decent. I’ve had it since June. Easy to set up just cut the plastic and it’ll unravel. Please be careful it does take about 72 hours to fully expand.

Not as firm as advertised. The size is great and it did not smell. The firmness is fine for me but isn’t firm enough formy 6’2”, 215 lb husband. He tends to sink a bit.

Wow! I am pleasantly surprised at the initial look at feel of this mattress. For the price and ease of shipping and arrival this mattress is amazing. I ordered the firm 12" King. This arrived with a hefty weight, no damage, it is the correct size and feels firm. I opened it, let it expand for 2 days, the required expansion rate, and slept on it for two night now. I am going from a $2500 Sealy med/firm to this. This mattress is turning out to be everything I hoped for! I was unsure of what to expect before ordering. I searched the reviews and nothing stood out as a red flag. So far, this has been worth the risk to save $thousands$ on a factory mattress from an overpriced dealer! My sleep quality has been amazing for 2 nights now!

A gift from my daughter’s Aunt and Uncle for her apartment and she loves it. It was a perfect decision to put this bed on her registry for her new apartment while she is in college. She highly recommends it.
