    So comfortable – guests didn’t want to leaveThe mattress has been a great investment for the guest bedroom. At times I have to sleep on the mattress and I’ve always slept really well – no aches in the morning. The guests who have stayed have said they were comfortable and were able to sleep really well.The mattress was smaller than 9 inches on one end of the mattress, but it wasn’t enough to cause a fuss.

    Perfect spare mattressPurchased a full for spare BR. First time buying a mattress in a box = pretty cool. Haven’t slept in it, but did lay on it. Very comfortable and supportive for the price and over all convenience of the whole thing. Perfect spare room mattress.

    Nice mattress to use with a box springIt does the job for mid price mattress for my teen son; I added a 2” mattress topper and box springs and he says it is comfortable.

    1 year later, still loving it!I’ve been sleeping on this mattress for a year now and it’s just as comfy as when I first got it, I prefer a firmer bed and this has been perfect. I am super happy with this purchase!

    Did my research…..Read multiple reviews for different mattress’ looking for one that does NOT contain “Glass Fibers”. Saw no one stating that this one did, ordered the mattress and before I unrolled it, I fully checked the label and sure enough contains “glass fibers” 😒 Immediately rolled it back up and sent it back for a refund. Played it safe and drove to Ikea where I can fully read the label before purchase. If you decide to order a mattress online, my advice is when it arrives, read the label before you open the vacuum seal bag as it will be almost impossible to send it back once it is removed and starts to rise.

    Good bed for a minute- now has a mountainThis bed was great when we first got it. It’s been 18 months. My husband and I are not huge people; each of us weighing about 200 pounds. We each have a side we sleep on. There is a “mountain” in the middle of our bed due to the sides sinking. I am looking for a new one.

    I’m Happy & Comfy with This Mattress! Short 72″There were so many mixed reviews searching mattresses, wow you guys make it hard! Lol. But, after much back-and-forth and thought and desire to stick to a certain price point because I don’t even know how long I’ll have this mattress, I kept with my price point and purchased this hoping hard it would work out.My last mattress-in-a-box was too hard for me and it hurt my hips (I’m a side sleeper). So, as people kept reviewing that this was both “too soft” AND “too hard” (I think more said too soft) considering my last purchase I wanted something a little bit softer.This is neither! For me it’s perfect, really. It’s firm yet a little bit soft, not too hard that it hurts my hips like the last one. I’m 5’6 and an average size for that height if that helps. Maybe heavier people might have more of an issue with these types of boxed mattresses as they say it’s too soft and I don’t know how much it might “give way”. The manufacturers should really put height/weight ranges on their products, seems pretty obvious. But, I guess they’d rather just sell more than sell to the right person.This mattress is shorter, though! It’s exactly 6 feet from top to bottom and since no one sleeps with their head on the top edge of a bed, you are losing several of those inches. I’m often finding my feet hanging off the edge so at 5’6 myself, I would not suggest this “full” size for anyone that’s taller. You’ll probably want a Queen or King. I looked up the typical size for a full and I’m seeing 75-inches versus this mattress being 72-inches. I am noticing those 3-inches missing. I don’t really mind if during my tossing around my feet end up going off the mattress a bit, though. I don’t think it messes with my sleep.It was easy to unroll! I let it go a few extra days to make sure it fully expanded to its true shape. Again, I’m very happy with my purchase and I’ve had this several months now!
