Style: 10" Charcoal Mattress + D200
Easy to put together, clear instructions, but very heavy and it helps to have an extra person move the beds. The mattresses are comfy and fluffed up nicely. The remotes are easy to use and the adjustments work great.

Very nice bed…so comfortable and easy set up as well. Mattress quality excellent. Remote very easy to use. One thing especially important to me is the height of space under frame. I like that I can use all of it for storage. Another bed I had had the mechanism that raised and lowered the mattress coming down into that space. I need that space because I live in a small place. I highly recommend this bed…very worth the cost!

Quiet! (almost silent) and Comfortable! Yes it stands a bit taller than many beds I bought the “Twin XL” 12” mattress version. It stands roughly 27” tall including frame. I’ve never used a foam mattress and it definitely took some getting used to getting into and out of bed and also movement while in bed. To me, psychologically, it Feels like fighting gravity more on a foam mattress. However it is no more physically demanding than a spring mattress. But this thing is COMFORTABLE! Bought this for my senior mother for health reasons. After assembling it, I tested it and WOW! Now I want one and am recommending it to anyone who brings up beds or sleeping in the future. I almost fell asleep testing it. I did not detect a strong smell upon opening the mattress however there was a bit of a smell similar to indoor house paint. Again not overwhelming and was gone within 15-30 minutes. Firmness for me was fine but I can sleep on soft or firm this seemed to be a happy medium for me. Easy to set up just unfold, screw in the legs, cut the zip ties, flip onto its legs and plug into power outlet. Screw quality seems sturdy and strong. The whole thing comes put together very well, nice and sturdy!

Ordered bed as it was what we needed for some medical rehab (rotator cuff) and reviews were good. Arrived as scheduled, was easy to set up, and all works as described. Yea! Bed is comfortable and I sleep well though do tend to slide down during night. One issue however: bed is totally flat, but had a retainer bar on only the foot. Mattress really tends to slide side to side. There are same grommets on either side on top third contemplating additional retainer bars. Contacted company at 877#. They said no, go search on line. Absolutely nothing on line will fit, this needs to be an available accessory, no issue with paying. Dyonery?

Easy to set up and the remote is simple to use. The head and foot adjustments work smoothly, and the zero gravity mode is incredibly relaxing. The mattress is soft yet supportive, and the Twin XL size is perfect for one person. I’ve been sleeping much better since using this bed. Highly recommend!

The bed came in 2 days! We couldn’t believe it, it was earlier than the estimate said and we thought that was super fast! So easy to put together, which wasn’t really putting anything together - the frame comes out of the box ready to go, just screw on the legs. The mattress needs maybe an hour to get to full thickness and it’s ready for bedtime! Remote is already programmed to the bed, and has several settings already programmed as well so that’s cool! I was looking for a firm mattress, and this is perfect - both my husband and I love the firmness of it - but it’s not so firm that it doesn’t feel super comfortable and bend easily with the adjustable frame’s various settings. So far I have no complaints, I would definitely recommend this bed, and for the price it’s kind of unbelievable! I am so glad I didn’t get one of the others I was looking at for double the price or even more - but some of them I feel like you’re just buying the name brand ?! Just my opinion, but I just can’t see how they could be any nicer than this one to justify that kind of price difference. Definitely 10/10 recommend for me!

Very comfortable bed and great replacement for a hospital bed. Added a waterproof mattress cover. It is very comfortable. The set up was mostly easy. It has an extra cable to sync with another twin XL to make a king. No odor was noted upon removing the item from the bag.
