    • Love it!
Arrived early , driver followed instructions. Great mattress. I let it sit and air out for over a day and it didn't need much to completely expand as it was about 95% ready out of the box. Be careful unboxing, as soon as you break the seal of plastic it explodes, I almost got knocked out. With that said, it is firm but I'm used to sleeping on a sagging couch. ... show more

    • Hard and Lumpy. No Memory Foam.

Review Image by geperry
I bought this based on the great reviews. I don’t know where these reviews come from. And that description is totally inaccurate. There is no memory foam memory foam gel memory foam any memory foam there is none. This bed is so hard and uncomfortable and lumpy. And I don’t have it upside down, I clearly see the side with the coils but this side looks like it should have a memory foam layer but it doesn’t , it’s hard and lumpy and I can feel the coils. I think they forgot to put the memory foam layer in there !!! ... show more

    • Definitely worth it
Super comfortable and perfect softness!

    • Comfortable, supportive, well-made, great value!
This is our first hybrid mattress (and our first bed-in-a-box) and it has set the bar high! It is more comfortable than our previous mattresses that were at least three times the price. It is firm enough to support my 220 lb husband and he has been waking up with less lower back stiffness/tension since switching to this mattress. At first, it felt a bit too rigid for me (105 lbs), but I quickly began to appreciate how it holds my body in alignment and keeps me from getting cricks and cramps. The box is heavy, but compact, so it is easy to store out of the way if you aren't ready to set it up immediately. One (fairly strong) person can singlehandedly carry/drag it into position, but two people makes it much easier. The mattress expanded quickly after opening; it was perfectly usable (and comfortable) within a couple of hours. ... show more

    • Love that it came all vacuum packed. The memory foam gives a really firm sleeping surface
I let this expand over one week. My daughter is the one that tested this because it went on her bed and she says it's. Comfortable and it doesn't sag in the middle. It is definitely firm but does shape to your body given that it has memory foam. Standard mattress pads and sheets fit over it just as expected so the size is spot on. There is little to no bounce because it is memory foam. So far I find this to be pretty high-quality and I would definitely buy it again. It came vacuum sealed and so easy to get into my house which I so appreciate. Gone are the days when you struggle to try and get the mattress to the door and try to bend it around the corners ... show more

    • Good Comfort / Affordable Price
Review Image by J.J
Very nice well made & comfortable 10in full size mattress. The mattress arrives in a box with air tight packaging, once you release the mattress it will take up to 24hrs to fully expand to its normal regular which is 75” L x 54” W x 10” thick. The mattress has a good look & design with dark grey borders & a white soft comfortable firm mattress top that is a hybrid with gel memory foam material. The mattress is definitely comfortable to sleep on with a good nights rest, the current price listed is a fair value for this full size. ... show more
