  • 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

  • Issues with Bed Quality and Support
Size: Queen Style: 11"
Under urgent circumstances, I purchased this bed due to time constraints, and I didn’t have the opportunity to thoroughly research options. Unfortunately, the bed is quite creaky, lacks proper support (including no edge support), and has left me feeling sore. Additionally, the mattress has springs protruding through both the top and sides. This bed has caused significant discomfort and exacerbated my back issues. ... show more
