We bought one of those foam mattress in a box things. Used the old one to cut it to fit and never looked back. Works pretty well.

Same here.  Be careful to make sure you take the one you're cutting OUT of all the top layers first. Get all the way down to the foam before you cut. One of those layers might be a fiberglass "fire sock". If you cut into the fiberglass fabric, it'll start to unravel and you'll have one heck of an itchy, bad-for-your lungs mess on your hands.

Best to search the internet for a "fiberglass-free" mattress. Good luck and happy sleeping!
