I bought this mattress over a year ago and I still get a great night's sleep. Unfortunately, I have to use a hospital bed and the mattresses that comes with those are awful! I needed something in my price range and this fit. After reading a lot of reviews, I decided on this one and am glad I did. I can no longer sleep on my side because of shoulder pain. Usually sleeping on my back caused it to hurt, but not with this mattress. I can sleep all night without pain! Even after a year, it's still comfortable with no sagging at all. Would definitely recommend this to anyone.

Never tried a boxed mattress before, but the rock bottom price on Prime Day made me decide to give it a go. I move around constantly at night, and I've generally gone softer to spare my back when on my side. But that means my back gets sore when I'm on my stomach. When I saw in reviews that it says firm but it's actually in the mid range, I decided to try this one. And I am very satisfied. Arrived in a box, inflated violently. It says to wait 48 hours to expand, I slept on it after about 12 and it was fine. There is a little bit of a smell, but it fades faster than 12 hours. It's definitely not a firm mattress, but also not soft. Right in the middle somewhere. And I can sleep on both my side and stomach without getting a back ache. And even the regular price is low enough versus a mattress store mattress that even if it only lasts half as long I'll come out ahead.

3stars based on rep only the bed was ordered as a 12” and 10” was delivered The amount of work to exchange it was a lot When I called in the rep from Ashley furn was pretty harsh saying it would expand Of course it was not did not But my daughter and her husband said they loved it anyway So mattress quality great Be aware the mattress may not be depth ordered that has happened twice now In their defense they delivery service went beyond the call of duty Excellent and kind

I have owned 10" king since 2000. It has been regularly slept in. I purchased it when I moved home to care for sick parent and slept in it for a year.... then for 2 years my 20yr old daughter, son in law and 2 large dogs . My only 100% preventable issue is not so much the mattress but caused by the frame I purchased from different manufacturer and failed to verify measurements. That's my own fault, preventable and hey learned the lesson of verifying so I very much recommend to verify and I personally would only go with solid not slatted. edges like to pop thru the slats ( ****again frame is significantly larger). Mattress sags a bit, the fabric on the mattress decided to make little bumps or "pills"(cannot tell once pad and sheets are on) . At times you can feel the springs around outer egde but do believe that is caused from the slatted metal frame which edges and corners pop between slats so after years of that...Still a very comfy bed though. For the price and kids using it for 2 years as a bed,couch, dog bed, trampoline etc.... it has held up pretty decent from the abuse. As of now it's a spare and visitors often comment how comfortable it is. I would reorder this mattress (maybe smaller out of personal preference). I would be using current one but opened it up in the family room and don't want to even try to get past a larger railing and up 2 flights of stairs.It does weigh 80+ pounds new.

Update 2023***** It is now October 2023. Almost 4 years since purchasing my king mattress. The mattress has started to give out. Back pain while waking up, dips from where we sleep. I knew it was an inexpensive purchase and wouldn't last like a 10 year mattress would. So here to say I got 4 great sleep years with it and on to the next one! Ok so let me start by saying I did more research on what mattress to purchase than I ever did with ANYTHING school related. I researched mattresses for about a month and had more than 20 in my cart until I finally narrowed it down to this one. I am SO happy I went with my gut and bought this. This was 100% within my price range. I mean a queen for $200? Yes please. Amazon offers the best discount for this specific mattress than any other website even on “Black Friday” and “fourth of July” sales, etc. Delivery was quick, 2 days and came in the form of “bed in a box.” However, I can usually pick up, assemble and throw out all my furniture and big box purchases but this was HEAVY. Be careful if going upstairs and grab some help women! I’m all about being independent but this just wasn’t working lol. After taking it out of the box, it took minutes even seconds to take its form but I allowed 24 hours for it to completely regain its shape. I will say even over the next 2/3 days it was still expanding little by little. The mattress itself is perfect for me and my boyfriend. It’s firm enough where we don’t wake up in pain yet so so so soft and cushion-y. I’ve never owned a better mattress and it’s a quarter of the price of others I’ve had. We’ve now had it about 3 months and there is no sinking in on either side, so far so good. There are always going to be bad reviews and not every mattress works for everyone. But taking the price into consideration, I would tell you to give it a try and take the risk because if you haven’t caught on by now I’m happy we did! I will now always buy my mattresses online!
