I was hesitant because of other reviews, but I really needed something to support my mattress and there weren't many options out there. It arrived on time and was packaged well. It was easy to install and fit nicely on the bedframe. It looks like cardboard in the way it's designed but it's actually a much stronger material and functions well. It doesn't move or make any noise. It cost a bit more than I expected but I've used it for a couple of months now and believe it's worth it.

It was a little tight for a king size bed but it works great. The weight of the mattress holds it down. No slipping of the mattress. Its quite when getting into and out of the bed. Noticeable improvement with sleep. Great product for the price.

We have a super heavy mattress that is a knock off brand of sleep number/select comfort and this fit the bill without having to use the multipiece plastic base that you get from their beds. Because of this bed support we were able to buy a bed with storage drawers underneath, then laid this on top of the typical support then put our mattress on it. There has been no shifting, no sliding, and our mattress stays put. We don’t regret purchasing this at all, I highly recommend this.

Fits the twin size bed and provided great support. I thought it cost more than it was worth. Flattened cardboard boxes would do the job just as well

I picked this up to add a little extra support under my daughter’s mattress on her captain bed and it worked out really well. It gives that added reinforcement without having to replace the whole setup. It was easy to position and feels sturdy once it is in place. I like that it folds, so it was simple to move and get set up where I needed it. Overall, it did exactly what I was hoping for and made the bed feel more supported.
