Imperius Foldable Box Spring, Bunkie Board, Bed Support Slats, Bed Boards for Under, Twin (60x30)

Fits a king bed perfectly and provides the exact support I was looking for. No assembly required, no noises. Because of the fabric elastic strip they have to fold them up and keep them together the bed doesn't slide around too much but you may need to add grip strips if your bed is on a flat base. But these boards are thin, yet very sturdy, and a good value. Be careful when you order though. I accidentally ordered the wrong size the first time.

I bought 2 twins for some bunkbeds. The boards are about 2 feet to narrow and about 2 and a half feet to short for the beds. The material seems flimsy and not connected very good. I feel like if i place it right in the middle of the mattress it might do a decent job at giving support to most the mattress. I do worry about the weight limit it would have for an adult, since they are so cheaply built. It was easy enough to unfold but doesnt stay in place since its to small for the area needed.

I bought the cheaper one again not noticing the size… this time for a full size bed, But it’s great, Sizes are confusing

The planks are relatively thin, and at first, they didn’t seem strong enough to support the mattress. However, after using them for a month, I found they do an adequate job of keeping the mattress flat. The main issue is that they don’t fit a full-size mattress—they are too short and too narrow. As a result, I’ve had to lean my mattress against the wall for extra support.

This product is significantly smaller than the size mattress that is meant for. I purchased it to spread out the load of full mattress over metal bed frame rails that were a little bit far apart because of the folds in the product it didn’t do that great of a job and it was really slippery. The mattress slipped around on the bedframe so we ended up returning it and the mattress worked better without this maybe for your specific application you’ll have better luck, but we found this to be kind of a piece of junk.

Worked better than expected!

10 out of 10 would not recommend it’s missing a slat to fit a queen size bed and it’s flimsy. The box was damaged upon delivery so I couldn’t return it and had to eat the lost. I wish I could return it and get my money back, I didn’t want to haul a traditional box spring up 4 flights of stairs but I wish I had 😭

It’s so small. Ordered a full size and barely covers the bed space. Keep in mind if you still buy this, it will affect the warranty of your mattress I was told by a salesperson. It also creates an overhang. If you buy a board it should fit the space like a glove, which this one does not. I returned it.
