Jumbl™ Mattress Support Folding Bed Boards 30" X 60"

This product is a long sheet of tri-wall packaging cardboard, folded into three and not very well edge bound with blue electrical tape. I have had better bits of cardboard as packaging from Amazon! It is possibly worth a tenth of what it is being sold for. This item is a massive rip off, the seller probably hoping that buyers will be too embarrassed to complain. In practice, you need such a large cardboard box to mail it back that you may as well just skip the initial purchase and put the cardboard box under the mattress. Amazon should be ashamed of selling this item.

This does the trick. No more sinking in the middle when futon is opened up. Gives the mattress great support. I would recommend this item.

This product is very expensive for simple cardboads taped and glued together. Be aware that also you would have to pay for a return. If you need something sturdy, don't buy this product.

Not as strong as I was hoping. Has already begun to sag.

I read at least one review when I was deciding to buy this that said they returned it immediately because it was cardboard. Cardboard or not, they work well for us. We have two, and we take them with us when we travel because all beds are not made equal. Bad mattress, bad back. These boards really help. They have traveled across the country and back and seem to be holding up. Very glad I bought them.

The item is not useful and doesn't help much in providing support as mentioned in description.
