OLINOA Twin Mattress Hybrid Mattress Memory Foam Bed with Headboard, Medium Firm Bed in a Box, No Assembly Required & No Bed Frame Needed for Bedrooms, Apartment, Blue

I rarely review items, but since this is a fairly new one and there aren't many reviews, I thought I'd put one in. The bed itself is quite nice. It has some good support but is also soft enough that it's comfortable. I had a very, very old bed (like 30 years) that needed replacing, as it was one of those old-style super soft mattresses with a box spring and sagged in the middle. I feel the difference with this bed when I sleep at night, not only with my back but with the pillow. My head sits way up on the pillow now instead of almost under my shoulder because the bed isn't sagging. The FedEx delivery of this was horrific (which is not Walmart's fault, though Walmart won't allow me to leave a review of the delivery - how convenient...). I had to set up the bed myself, and I'm a small person (a little over 5 feet), and I managed to do it. The bed (twin) was pretty heavy to unroll, and they had a gazillion plastic wraps around it (guess the company never heard of environmentally-friendly wrapping...) that you have to cut through and then slide out from underneath the bed once it's unrolled. Be careful if you have kids! The plastic wrappings are thick, and if they play with them and get wrapped up in them, they could suffocate (yes, I know this is common sense, but as we know today, "common sense isn't so common" anymore). Once the bed was unrolled and started to puff up, it was actually easier to move than when it was rolled up. I was able to sleep on it about 9 hours after I set it up (I didn't have any bed or inflatable mattress to sleep on, so I had no choice). It does take at least a few days to inflate properly, though. The one thing that is a disappointment is the headboard (which is why I give it 4 stars). The instructions make you think it's super easy to attach. It isn't. It has a zipper going around the edge of the bed, but the zipper doesn't have that straight part at the end, which is supposed to attach to one side of the zipper and make it zip up (like a jacket). That straight edge is sewn into the bed. So there is no way to zip it up. But the headboard does sit on the floor at the same level as the bed, so I basically just shoved it against the wall and the bed against it, and it's holding pretty well and not falling forward.
