    • BEST MATTRESS EVER MADE.
Style: 7" Medium-Firm Size: Full
Fantastic mattress. Second purchase. First a King then a Full Size. Firm Memory Foam that conforms to your body. Never dents or sink in permanently. Best Mattress ever. Great night sleep. Esp for people with back, hip or shoulder pain. This is the perfect mattress by far. I’m a Retired Nurse and I would suggest this mattress to everyone. Takes 48 hrs to open up completely. Best Buy Ever. ... show more

    • Shockingly, zero lower back pain on this mattress!
Style: 7" Medium-Firm Size: Full
I have serious lower back pain, and I've had it since 5th grade after a bad fall. Mind you, I'm 32 now. This bed is for my son. My son and I have been sharing for a week while my new one comes in after a massive flood left us having to start over. ZERO back pain for me on this bed! The price is unbeatable! So fricken comfortable! No noise, minimal sleep disturbances. I'm regretting not buying one for myself! ... show more

Style: 7" Medium-Firm Size: Full
I originally bought this mattress to replace a mattress that I left behind after an apartment fire I wasn't sure whether this was going to be a temporary matches or not I have been using it for a couple months now and it is comfortable it's not as thick as I would like the mattress to be and actually for my bed frame it's not going to work and I'm going to need to buy probably a mattress and box set but for most people this would be a good comfortable mattress at a great price ... show more

    • Outstanding, “sleep through the night” mattress
Style: 7" Medium-Firm Size: Full
Bought this mattress for my 14YO son, as we moved into a new house. He’s a two sport athlete recovering from shoulder surgery. He doesn’t get overly enthusiastic about much (aside from sports and video games), but after the first night’s sleep, could not stop talking about how “AWESOME” he slept on his new mattress. Super comfortable - “firm with the right amount of softness…and great support for my shoulder”, he said. And he went on to remark, “I didn’t get hot in the middle of the night like I did with my old mattress so I slept all the way through the night”. With that feedback, his middle aged mother may be getting one of these “cool all night” mattresses, as well😂🤣😂 ... show more

    • MORE ON THE FIRM SIDE THAN EXPECTED-NOT GOOD FOR SIDE SLEEPERS
Style: 7" Medium-Firm Size: Full
I purchased this mattress as a quick replacement while I moved to a new place to sleep on and let me tell you, I'm used to sleeping on a nice plush mattress. After sleeping on it for the first time, I woke up the next morning with pain all over my body. This is a HIGHLY DO NOT RECOMMEND if you are a side sleeper. It is just TOO firm. If you're used to sleeping on solid floors, well then yes this mattress is an upgrade. But if you're used to sleeping on a nice lovely plush mattress top, well then no this mattress is a freakin nightmare. I think the mattress is a great buy if you are someone who sleeps on their back and enjoys a firm mattress, anyone looking for anything plush or medium, look elsewhere. ... show more

Style: 7" Medium-Firm Size: Full
This is a comfortable bed. My only concern is I do not feel that there is any cooling factor. We got this because live in Florida and no coolness is felt. That was a disappointing!

    • Poor Fit and Finish
Style: 7" Medium-Firm Size: Full
I was very disappointed with the fit and finish of this mattress. It was smaller than it should have been for the size and did not have a uniform edge or look remotely as refined as it does in the photos advertised. I had purchased this bed for my daughter and it left gaps around the bed frame due to it being smaller than what it should be, I was afraid of her getting a hand or foot caught between the mattress and frame while sleeping. I never slept in it and only laid in it for about 5 minutes after unpacking it. Again, not impressed at all. I ended up replacing it with a Tuft and Needle brand mattress that was about $100 more and I am much happier with that one. ... show more
