I needed the storage space under my mattress and this looked sturdy. It is. however mattress support is lacking even with a traditional mattress. Just not enough surface area supporting mattress. I decided to go with a foam mattress and the manufacturer recommended I just use plywood.
With the plywood my foam mattress works great. 1/4inch plywood will work well.
3 rating is simply because this frame does not appear to me to provide enough support for any mattress; the surface area is just too low.
sturdy but lacks surface area on mattress
