I've had this mattress since early 2022. I absolutely love it. This mattress has far exceeded my expectations in comfort and longevity. To this day the bed bounces back as soon as I get up. I sit on the edge A LOT and it hasn't created an indentation, to my amazement. For reference I'm 5'8" and currently 200 lbs. I bought this when I was at a heavier weight, about 240 and it was just as comfortable and reliable then. If I ever have to buy another mattress, it'll be this exact one. It's on the firm side but not ridiculously firm. You don't sink into the bed, either, which I used to hate about my previous medium-firm mattress. It really is the perfect affordable mattress. Especially if you're like me..disabled, on a tight budget and dealing with various medical conditions that affect quality sleep. 1I keep it in a mattress encasement to prevent dust & mold spores because of living in a high humidity area. The only "negative" I've experienced is when changing the sheets, I've noticed threads from the diamond pattern coming loose. This isn't a big deal to me at all, but worth mentioning.

Bought this mattress because where I bought 100% of all my mattresses and box springs for over the last 30 years closed VERY sadly namely Sears. I had to buy a new mattress because the one my 18yo son who is 6'3" 280ish was sleeping on was giving him back pain. This mattress exceeded all of my expectations of comfort and quality and immediately solved my son's back discomfort and pain. The fact the nearest mattress store to me is now a 25 minute drive AND the affordable price of the mattress made me willing to buy it untied. In y suns opinion it offers a very good balance of plush comfort and support for an XXL heavy male. I tried the mattress and would agree with my sons evaluation. Now for the ONLY criticism. We liked this mattress so well I went to order one for my other son (also XXL 6'+ 280+) and to my complete shock the price had GONE UP by over $130 now placing it's cost close enough to an OTC mattress purchase I decided to go buy a full size mattress from the local store as the near hour round trip is now justified due to the cost factors are equal. If this mattress can be had at it's original price of $130 less than current than yes it is well worth buying, but at its current price I would recommend you buy OTC alternative.

This mattress was packaged well when it arrived and I was able to open it with ease. It came with a little thing to open the plastic without harming the mattress which was nice! It expanded fairly quick and was at 10 inches in a day. The smell did linger for a bit but eventually it went away. As far as comfort, I’d say it’s a good 3.5/10. I am a 5’9” male weighing about 145-150 lbs and it doesn’t sink all that much. My lower back pain has improved significantly and I sleep better throughout the night. I was torn between the 10 inch and 12 inch but got the 10 due this being my first “mattress in a box” purchase. My brother in law is 6’6” and when he laid down on it, it sounded like it was struggling to support, I’d say just go for the 12 inch and spend the extra couple of dollars. All in all, it’s a good mattress and I’m satisfied. My main problem was my lower back and it’s helped tremendously. It’s comfy, not too soft but not too hard in my opinion. I would definitely buy this mattress again and have not been disappointed. Will provide an update a few months from now. Update: I’ve had the mattress for about 6 months. I’m keeping the review the same. It’s held up well. The edges are a little weak as I can’t sit on the edge without sliding off. It definitely helped in a pinch and is still pretty comfy. I’d say I sleep a little on the hotter side on this mattress. I’ll keep it but for a guest room bed because it isn’t bad at all but not my full cup of tea. Thanks for reading!!

This is the PERFECT mattress! It’s simply underrated!!! This is better than a $2,000 mattress! It took less than a minute to get into shape, it’s very lightweight, and it’s so comfortable! It’s been about two weeks since it’s arrived, and it still feels like it’s the first day! My whole family loves this mattress! There are no springs poking out of anywhere, and it’s very firm! The package was so small, I doubt a small TV could fit in it. But once the mattress was put into place, it instantly became huge! It’s like a big, comfortable, compact, marshmallow! This mattress can help you get more deep sleep! I love this mattress so, so, so, SO incredibly much! I absolutely recommend buying this! One of the best mattresses I have ever slept in and bought! It also stays cool all day and night long, whether or not there is a bed cover! 😊

Quality of workmanship is great. The first several nights were comfortable. Now that I’m about two weeks in I’m having some discomfort while sleeping and waking up sore. I’m not sure if this is me or the mattress. The only concern I have with structure is it seems to already be caving in the middle. I wish I would have saved the money and bought one in store. I have a foam mattress topper, pillow topper and mattress protector.

I've had this mattress since September 2021 and it's been perfectly comfortable with no issues the whole time. Bought for $360, not sure how they managed to get the price down so much, but the product I bought in 2021 has been excellent.
