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.

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.

I wish I would’ve done more research before buying this bed. It’s not the most comfortable bed. We’re actually thinking of getting a new one because it’s really hard on our backs and we can actually hear the springs or what we think our springs already and we’ve only had it for 4 months. I wouldn’t recommend getting this bed. We have it in King.

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!
