I used this for a craft project and had enough left to replace the foam in both of my dog cushions. Much cheaper to buy foam this way than from a craft store. I bought a much better quality 3 inch foam for my King bed, it was much better and heavier than this item. I would not use this for a bed.
This was the WORST mattress topper ever!!!! It does nothing for your bed, and there is no weight or layer to this. Do not waste your money on this because your mattress will feel the same. It's such a thin layer that there is no point to putting this on your bed.
