  • Happily surprised!
Great mattress, happily surprised! Unboxing was easy—careful cutting it open! I opened it first thing in the morning so it had time to expand and I was sleeping on it that night. I have severe arthritis, back issues, blah, blah, and was looking for comfortable but not $$, like my last mattress, which didn’t stay comfortable very long. So I’ve had this about a month, two? And I still think it’s great. I’m sleeping better and waking with less stiffness. It’s supportive yet gives to your bones, which is exactly what I was looking for. Now if I could only find some pillows ... ... show more

  • Buy this mattress!!
So easy to unpack. Open thebix, remove the plastic and lay out mattress. In hours it is ready. Both my husband and I have been enjoying sleeping on this very comfortable mattress. Both of us had aches and pains which have diminished since we got this mattress. I would definitely recommend you buy this mattress. ... show more

  • A firm mattress, not soft.
Update 2 weeks after 5/04/2021- I have to say that I am very disappointed with this mattress. It’s not as soft as the description made it sound. I haven’t had one good nights sleep in 2 weeks. I read that it takes about 4 weeks to adjust but honestly, I can’t see it getting any better. I wish I had went to a mattress place now. If you like a firm mattress then this will good for you. If you’re looking for a soft mattress, keep shopping. I received my mattress today. I will wait the full 72hours before I use it. I will update my review after I try it out! One person can open the compressed mattress but 2 people would definitely be better! ... show more

  • Very nice mattress for the price
I have had this mattress now for 5 months and I am very pleased with it. It is comfortable and not sagging at all. I spin it every 2 months so it will wear evenly. With the handles on the side it's easy for me to do it myself. I like that you can take the top cover off the mattress for cooler sleeping. That was very important to me. After I opened it I let it sit a full 3 days before using it. It puffed up nicely and there was no odor at all. I needed a mattress but with the pandemic did not want to go in stores. I researched for a reasonably priced mattress and choosing this one has turned out to be the right pick, as nervous as I was to buy one site unseen. I highly recommend this brand. I have the 11" memory foam. ... show more

  • Took 1 week to expand to true size. Best for my side-sleeping. Easy handling.
Lugging this around and up the stairs by myself was manageable, thanks to the compact size and packaging it arrived in. Once unboxed/unwrapped, the mattress took a week to finish expanding before it measured its true 11” width. I’ve tried other popular foam mattress brands in-stores before, and I didn’t notice much difference from this one, which is more than half the price. So far, this foam mattress has elevated my side-sleeping comfort. And, I feel my overall sleep did indeed subtly improved. I haven’t had better. Drawback: Although this comes with a zipper cover, it’s not waterproof and the material looks non-durable against friction, so I got my own zipper cover to use over it. ... show more

  • Don't Second Guess, Buy it!
I never really considered my sleepless nights were due to having the wrong mattress. Initially, I was skeptical on purchasing a mattress "in a box" but I'm so happy I did. No more tossing and turning throughout the night. I actually get a full nights of sleep. I love when I lay in the bed of softness and how pleased of the comfortably this mattress gives. I immediately fall into a deep sleep. I get up with NO backaches and/or NO hip or butt aches and pain. This mattress is absolutely a "BEST BUY"!!! ... show more

  • Great sleep.
Omg. I was so worried about buying a bed online, but this bed is amazing. I've only had it a week and I'm already sleeping better. Definitely worth it.
