I bought this to fit a full size 4" memory foam mattress topper. I gotta say it took 3 of us. 1 to lay on the memory foam and 2 of us to get it shoved in and keep pulling the bag up. But it actually fit! My arm was dying using the hand pump so we used a vacuum. It worked better than the hand pump. Due to what I was storing it did not shrink very flat, but compared to the size of the memory foam it shrunk a lot and will definitely save space! The bags arrived today so I dont know how well it holds up long term but the bag was very sturdy yanking it up around the foam. Didn't tear or stretch. And it actually fit!
