    • Perfect...
Size: 76''x80''
Got it yesterday and installed it on my bed last evening. Took a while to get it adjusted to fit my bed, but finally got it done. Really improved the stability of the mattress and took out that annoying feel of the metal slat in the middle of my bed too.

    • Well made at a good price.
Size: 54''x75''
Decent price, seems soild and well made I like the removable covers incase they need to be washed, although I don't see it being something that will need doing.

    • Perfect solution to bring your mattress down to the size it was meant to be….
Size: 76''x80''
I initially ordered this to replace a box spring and lower my bed for my elderly disabled husband…. I have a large king size canopy bed with a full top. When you add a box spring which is required with my frame and a mattress, it sits too far up to climb in. He has had surgery, and I have had surgery and we struggle to get in and out of bed daily. I thought with this item, I could lower my bed and not make it so high up. The day came for the truck to haul off the box spring and once it was gone, I realized this wasn’t going to work because there were no slats. Just a bed frame and you need something to hold the boards up and in place long term so, off to the store I go and have boards cut to place on my bed frame. That was a huge improvement but I wish I had known about that before hand. The king sized board comes in two pieces that you lay out the opposite way you would expect to. The boards themselves are not very heavy and have air chambers all the way along the piece. The boards are placed in a zippered pouch for cleaning and replacing. Once they are set up, they are strong enough to hold and support your mattress and those who sleep on it nightly. This is made very well with quality materials. Its a simple idea and a decent design that changes the way adults use their beds. Now our bed is at a normal height, is easier to get on and off and benefits us both. I am so happy to have a normal bed, that is not hot and rotting underneath us like a box spring might. There is no difference in the comfort of our mattress except that it feels more supported evenly. There are no weak spots and the entire top is even now. Overall, this is a great idea for adult beds as well as kids and teens. ... show more

    • Slippery
Size: 60''x80''
I bought this to try to reduce the height of my queen size bed. It does work at acting as a support board for your mattress and is very slim and easy to install. It simply unfolds accordion style and lays down on your bed frame, The downside I did notice is the material is rather slippery and has caused my mattress to start sliding off the bed, and in the middle of the night that's more than a bit disruptive. The board is well built it is made of corrugated plastic with a vinyl zip cover over top of it, I do wish the cover had grip than the slick vinyl. For the price it is not bad but I would prefer a better-quality board that would not be so slick. ... show more

    • It's a board that goes on the bed, and it does its job!
Size: 54''x75''
I bought it to go on a platform bed frame with slats that are further apart than is recommended, so that the mattress can't droop between the bars. Works just fine!
