need 72x84 x4in thick
NO... Home Depot is NOT gonna cut this for you.
Would not recommend spraying it. Needs cover for sure.
need foam 4 in X 6 feet X 84in
3 rolls , it's 24" wide. You can also find one piece foam pads although I would suggest a new mattress and box springs. Adding foam is a short term fix and good sleep is important to good health and happiness.
Yes it's an excellent product. Hasn't lost it's shape at all.
No try 4 inches it’s firm More will be like a bowl See my review. If you cover it with tight velvet it holds its shape and looks beautiful
It is NOT recommended for outdoor use. It acts as a sponge soaking up the liquid.
No support whatsoever.. do not waste your money
No Maybe 2 inches INSIDE of present cushions
