  • Not like sleeping on clouds.
Item Firmness Description: Medium Firm Item Thickness: 14 Inches Size: King (U.S. Standard)
Ease of setup: check Opinion: Divided Initial impressions: not bad, not immediately uncomfortable My husband said he was having great sleep. Yesterday he had a change of tune and said lately his body feels like it’s been beaten up. This mattress is not like sleeping on a cloud as other reviews might have someone believe. It’s pretty firm. I’ve never had a “firm” mattress before so it could be worse. From the first night I have had hip pain. Now I have back pain. I wake up sore every morning. I’ve since ordered a mattress topper to try and salvage the situation. Maybe this mattress will work for someone. ... show more

  • This is a great price and actually an amazing mattress.
Item Firmness Description: Medium Firm Item Thickness: 14 Inches Size: Full XL
So far so good! The last mattress that I purchase in 2020 was a little firm, so I had to buy an egg-crate type pad to put on it, so I wouldn't get the sore shoulders and hips. Because of that experience, I figured why spend a thousand bucks on a mattress, to just cover it with a soft topper and not benefit from the mattress? So I thought you can't go wrong with a lesser price if you're going to put a topper on anyways. Well, let me tell you, I've been on this for a week, and was expecting to need to put another eggcrate on it, but it's great! Just right! I have not had a night where I woke up with any sore spots from the mattress. The quality for me has been excellent. I would agree with other reviews, that when you sit on the edge to get up from, or get into, the bed, it does squish down, which for me is ok because my bed frame is super high up, and I don't ever sit on the edge of my bed to put shoes on or anything, I'm only ever on the edge briefly going to bed or getting up out of bed. The price was actually amazing for a mattress, including delivery for me. The bed expanded perfectly out of the box, very quickly for me, and I let it sit a couple of days, but I think it would have been fine to sleep on it on day one. It felt like it firmed up and did it's thing straight out of the box. Since we like it, we ordered a Queen size of the same mattress, and the price was also a steal for a Queen size inlcuding delivery! Can't beat it! Just keep in mind, if you're someone who spends a lot of time sitting on the edge of your bed, you might want something different with more edge support. But you can use a chair or stool to sit on to get dressed and put your shoes on just the same. Enjoy! ... show more

  • Nice mattress
Item Firmness Description: Medium Firm Item Thickness: 14 Inches Size: King (U.S. Standard)
We purchased the King size in the plush. Mattress arrived rolled up and nicely packaged. We removed and sliced the plastic open with the included knife (thanks for including that). No noticeable odor which was really nice! The mattress was quick to inflate and we allowed it to sit on the floor and do its thing well over 24 hours. I would say 90% of the bed inflated immediately. The corners were the only parts that remained a bit compressed. Even after 24 hours, the corners still seemed to sag a bit. We put the mattress on the bed frame and allowed it to sit there for another 8 hrs., before putting on the mattress protector and sheets. The corners still haven’t popped up as much as the rest of the mattress. Went ahead and made the bed and slept pretty good the first few nights, so far. The corners of the mattress are still concerning as they still haven’t fluffed up. This is the only reason for removing 1 star. The mattress is very comfortable but we haven't notice any real cooling effects. Time will tell how this mattress holds up, and will revise my review if anything changes. ... show more
