Can you cut a memory foam mattress?

Question

I want to cut a King mattress into half to create two twin XL mattresses....it's more economical to do it that way.
Is it possible to cut the memory foam mattress into half?

Answer 1

If the mattress is just foam, use an electric knife, the kind that you carve the Thanksgiving turkey with. If this mattress has a bound edge, Not recommended.

Answer 2

It really isn't a good idea to cut a mattress. First of all there is the obvious difficulty of how you do it and do it tidily and evenly. Memory foam could in theory be cut because it is just foam, you wouldn't cut an innerspring because it would affect the spring system. It just seems a bit of a waste to deface a perfectly good mattress but I can't see it ultimately affecting the performance. Memory foam is basically a bunch of cells and they work by displacing air through the cells when you lie on it. That will still happen even if you take a big slice out.

Answer 3

Don't do it to a new mattress! While the mattress does seem to be the same from one edge to the other, there are also two layers of cover that could not magically become two separate covers.

So you'd save a few $, but void your warranty immediately, and need to find a way to wrap it up nicely.

Answer 4

Is this the whole mattress, like a tempurpedic, or just one of the toppers that is like 4 inches thick. The topper you could cut, the real mattress I wouldn't do.

Answer 5

yes , just use scissors , mine turned out fine

Answer 6

yep. it is a very tight fiber.
