Why do Mattresses Sag? 

Sagging appears when the mattress receives too much strain from a person’s body in a certain spot. The area where your mattress will get more pressure is close to the hips, back, and shoulder.

How to Fix a Sagging Mattress with Plywood? 

To give the user fine coverage on a sagging mattress, you will need assistance. Plywood provides the stability you need to repair or fix your mattress

Without a box spring, it will be necessary to lay two pieces of plywood. You have to place it between the mattress and the bed frame to maintain a uniform surface. Although plywood doesn’t fix the sagging mattress, it helps lessen its effects.

In this way, there will be fewer effects of sagging and you can sleep with comfort and ease.
