  • This Thing Works. Period.
Size: Queen
Ok. We were at our wits end with our bed. The sagging made us feel like we were literally in a rut. Lol. We were getting ready to junk it and get a new one. After looking around for options (foam or actual plywood were considered). We found this and decided why not? Worth a try and at $105 way cheaper! We received our Bunkie Board but it took us another day to actually put it on the bed. Why did it take so long? Bad backs. Once we put it on we were sorry we had even waited! Within minutes after putting it on we immediately felt the difference in our mattress. Within 2 days the pain and stiffness we usually had getting up from the bed was reduced! Now within a week we are up and at'em ready to take on the day. We highly recommend this product. Try it before you buy a new mattress! It works. ... show more

  • So far, so great...
Size: King
Easiest installation ever and fits our king bed with slats perfectly. Only used one night, but immediately noticed a difference the next morning. No soreness or back pain. This bunkie board seems to assist well in providing proper spinal alignment in the places the mattress was previously slightly dipping over the unsupported slats. Bonus, no funky product or warehouse smells and the boards were packed well. ... show more

  • It doesn't slip.
Size: Queen
The Queen bunkie board provides firm and even support for your mattress, preventing sagging and reducing noise. Its low profile doesn't raise the bed, and the non-slip design keeps the mattress in place. It's a great option if your bed base has separate slats or you want more stability without using a box spring. ... show more

  • Helps to give a little lift
Size: King
I ordered this bed board more to give our bed a little bit more of a lift. We have a platform bed and it's a tad low- I'd prefer it to be about an inch higher but didn't want cheesy bed risers. This board is definitely strong enough to handle our king mattress, and it has added a little bit of height. The mattress does not slide around, and it seems to make the bed a little sturdier, as well. Our bed didn't make much noise before, and this didn't add nor take any noise away. It is easy to install and use on your bed, so if you are looking for additional height or to give more support if your slats are spaced out, this will help. ... show more
