How to soften a firm mattress

Updated February 21, 2017

A chiropractor will assert that if you're prone to back problems, a firm mattress is the only way to go. A soft mattress causes your spine to sag, putting stress on your ligaments and tendons, while a firm mattress keeps those ligaments and tendons well supported, relieving stress, aches and pains. If your mattress is just too hard, take action so the mattress can still mould to the shape of your body and offer you a good night's sleep.

Purchase a foam rubber mattress cover, if you have back issues and need to relieve pressure points. Buy a cotton mattress pad for simple extra softness in size that matches your mattress. For example, if you have a queen-sized mattress, buy a queen-sized pad or mattress cover. For extra comfort and cushioning, select a mattress pad with a pillow or wool top.

Remove the fitted sheet from your bed and place the foam rubber cover or pad on top of the mattress. Line it up so the corners match the corners of your mattress.

Look for elastic loops underneath each corner of the foam cover or mattress pad. Pull the loops over the bottom of each mattress corner to secure them together. Replace the fitted sheet back on your mattress.


If you have allergies, select an antimicrobial cotton mattress cover.
