If you’ve never tried this type of mattress before, head to a local brick-and-mortar store to find out how they feel compared with inner-springs. Although you can get a less expensive foam mattress shipped to your door for free, it’s good to get an idea of the differences.
“If you quickly lie on a store mattress, especially if you’re tired from shopping, you may go too soft,” says Ben Trapskin of the blog sleepsherpa.com. It takes about 30 days to tell if a mattress suits you, so if you want to buy right then, go harder than you think—and check the return policy!
Check the density of the memory foam. “High density” is more durable and firmer and conforms to your body the best, but it can also give you that “stuck” feeling and make your sleep hotter. You want a mattress with a majority of “medium density” foam, which will give you the best feel.
