    • Best experience I’ve had buying a mattress
Size: Twin Style: 10"
Love how easy this was. Affordable, clean, comfortable, easy instructions. It sleeps like a dream, not to firm, not to soft, just right!

    • 3 to 4 yrs of owning and myonly reccomendation is.....
Size: King Style: 10"
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. ... show more

    • It's solid so far
Size: Full Style: 10"
I got this mattres about a month ago, and I currently have no complaints. When I first opened it, it did have a slight latex/plastic smell, that I could pick up when I put my face close to the mattress. I cracked a window and opened my doors to let it air out, and after a few days it was gone. It also took a day to inflate, which I've heard is normal. It definitely doesn't feel plush, the layer of foam gives it a very medium-firm feel. I weigh about 150 and tend to sleep on my side, and I feel it supports my weight well. It might be best for heavier sleepers like myself, because it doesn't isolate movement at all. If I were sleeping in the bed with someone else I'd likely feel their motions for sure. It only creaks a little bit, with significant motion. I don't believe it ever fully rose to 10 inches, it's just a little short of that when I measure it. I just moved away from my childhood home, so I needed a cheap mattress that would be comfortable to sleep on for another year or two until I can afford a better mattress, and I feel like got what I paid for. I'm satisfied, but not particularly excited or hateful about this product. EDIT: It's been about 6 months with this mattress now, and I hate to say it, but it has started to make my back sore at times and it creaks loudly and constantly. I wish I'd gotten a memory foam mattress. Given my circumstances, I'm not at all upset at this, but it's a shame as I intended to keep the mattress for a year or two and I'll have to replace it as soon as I find the money this year. This might be better for a guest bedroom or a temporary, short-term solution like in my case. If you have the means to invest in a pricier mattress, I would recommend doing that. ... show more

    • I find it to be a good mattress for someone who's constantly changing positions while sleeping
Size: Twin Style: 11"
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. ... show more

    • Good Mattress
Size: Queen Style: 11"
This is a very comfortable and firm good mattress, even better than I bought in IKEA 300 bulks higher. Sleeping on it make your waist and back being supported enough.
