Imperius Foldable Box Spring, Bunkie Board, Bed Support Slats, Bed Boards for Under Mattress, Queen 60 x 48 in

Sagging mattress from bed frame missing bars or slats totally fixed. Guy queen frame even though looked a little small. If the mattress needs replaced later I'll keep it for the frame since I have a taller one that allows under bed storage. If I switch frames I'll give it to whomever in the family uses it. Wasn't too heavy to unload or use.

Ok so this is cardboard, but it’s heavy-duty cardboard. So if you’re not putting a lot of weight on it, and if the slats on your bed aren’t too far apart, then it should be fine. I’m just super irritated that the measurements are wrong. It’s too long by an inch, why means i have to cut the straps and have an overlap (which I’m doing at the base of my bed, in hopes of not really noticing it). This has fundamentally become the issue with Amazon - poor quality control. You literally don’t know if what you purchased is what will actually show up.

Good quality

Useful for what it is needed for but man these are pricy hard cardboards! Came in folded so I don't understand the costs. Not only this seller but bed board as a whole category of products is like $$$$$

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.
