  • Stylish, Sturdy, and Super Comfortable!
Color: White Size: King Style: 8 IN
This bed exceeded all my expectations! The frame is incredibly sturdy, easy to assemble, and looks sleek and modern with the upholstered headboard. It adds a touch of class to the room without being too flashy. The mattress is surprisingly comfortable — supportive without being too firm, and it offers a great night’s sleep. I woke up feeling well-rested and ache-free! The height is perfect, and there’s even enough clearance underneath for storage bins. If you’re looking for a high-quality bed that’s both affordable and attractive, this is the one. Highly recommended! ... show more

  • Soft mattress
Color: White Size: King Style: 8 IN
Omg this mattress is so soft and comfortable. It takes the shape of your body when you lay down but bounces right back up the minute you get off the bed. The quality is amazing and was super easy to set it up.

  • Doesn't last long
Color: White Size: King Style: 8 IN
Had a different mattress for almost 9 years. It was great and just needed a new one so found this one. It is the same type and thickness so figured it would be equally as good. The mattress did seem really nice. Inflated, was a good thickness and firmness. A year later it was as if it had been used for 10 years. Lumpy, dipping, firmness in areas completely vanished. 1.5 years and we are about to search for a new mattress. Expected more out of this one. Save your money if you don't want to have to replace this within a year or so. ... show more

All these reviews suck… This Mattress is amazing for the price. It comes 8 inches thick like advertised. I’ve had it for almost 3 years and it still feels brand new. It is a little stiff at first but give it a couple days to break in and you’ll fall in love. It’s a medium firmness so not super soft but not back breaking hard. 10/10 would recommend. ... show more

  • Not for back pain but good mattress!
Color: White Size: King Style: 8 IN
Update (3/30/24): I was hoping this mattress would soften some as it was too firm for my back. It has not. I’ve had to put a topper which helped some but not enough. If you have back pain or shoulder pain, I don’t think this is the right bed for you. It’s great quality though, so I’m not dropping my rating. It just isn’t working for me. ********* Just received this order today (6/5/23). I will update once I’ve gotten to sleep on it regarding comfort and pain relief but to note so far: 1. Box wasn’t as heavy as I expected (huge bonus), as I was having to maneuver it on my own. 2. Other reviews mentioned gassing off but considering other memory foam beds I’ve gotten in the past, this one had barely any smell at all. I barely notice it when walking into my room, which I closed off from both my dog and toddler! 3. It immediately expanded to the 8” within an hour of opening. For those that haven’t opened these mattresses before, it would be good to know it’s rolled in half and sideways. So unroll it horizontally across your bed versus vertical to make it easier to lay it flat in place and then open it up. If you have another person, this will be much easier to stand the mattress up to pull the folded half out and lay it in position. I bought this mattress for pain relief since I have a degenerative disc. ... show more
