0.75-Inch Heavy Duty Mattress Support Wooden Bunkie Board/Slats with Cover, King, Grey

It's called a bunkie "board" but really it's not. It's just a bunch of wooden slats that have absolutely no structure or strength - the only way these are effective is if they are placed on top of an already solid foundation. Your typical bed frame has three bars across and hollow space in between. If you place this "board" over a standard bed frame, the wooden slats just sink in between the bed frame and provide zero support. Incredibly misleading photos, do not purchase this unless you already have a foundation (so then why would you buy it....)

I purchased this product to provide additional support to my sofa couch sleeper bed. I had replaced my old thin mattress with a foam mattress. The foam mattress was very squishy and needed additional support so that my guests didn't feel the metal bars of the pull out bed. This product was the perfect answer! It also stores very easily inside the couch. I just leave it underneath the mattress. I highly recommend this product to anyone wanting to increase the comfort of their pull out sofa bed!

Very heavy and there was one slat that was split with a huge splinter sticking through the fabric/protective cover. Disappointed in how easily the wood poked through he clothe protective cover. It is also shorter than the mattress length and had to be rotated 90 degrees in order to cover most of the mattress; so not the slats are going vertically instead of horizontally. Definitely not meant for shipping as damage will be done. These issues will void the warranty on your mattress if you are not properly supporting it. Extremely upset, that no one has contacted me, nor tried to fix the issues. I would love to hear what the company have to say and if anyone else has had similar experiences.

2 out of the 13 slats are 37 1/8" wide, and the rest are 38 3/4". The actual width of the twin frame is 38", though the two shorter slats work fine. However, the longer slats don't fit at all, making this completely useless. Will be returning (if I can)!

This arrived super quick! We used it to replace a bunky board on our son's bed. Easy to unroll and place on the bed. Had no problem with the fit, unlike some others have posted. It fit perfectly. Snug, but perfect. I would not want it to be moving around.

It’s attached fabric covered boards to replace a box spring on a platform bed. It does an excellent job of providing added support to my memory foam mattress and amps it up to “can bounce a quarter off this thing” firmness, which is exactly what I wanted. Nice quality, well packaged.

I bought this for my king size bed because the one that my bed came with was sagging down a little. It works great the only negative I see is it was a little short it works but may not have if I had not left the old supports in place. I posted a picture my old supports are the wood and the product is sealed in the gray material and you can see that it's a little short for my bed. I'm using it and it works with the old supports.

Bought this to replace a bunkie board on one of my kids beds.. bought the full size version and almost all of the slats are too large to fit inside the bed frame and hang over the edge. Now I have to figure out how to return a gigantic box and my daughter is without a bed still, until I can get something different.
