can you use plywood or a wooden box instead of a box springs?
For optimal support and durability, the plywood under a mattress should be at least 3/4 inch thick.
yes
It was recommended on WebMD to place a piece of plywood between the boxspring and mattress. However, you can also try rotating and flipping the mattress. If it is more than ten years old, you will do best to replace it. Box springs do not need to be replaced if you are purchasing a same size mattress. Never use plywood to stiffen a mattress. If it is too soft, the it is worn out. Replacing it is the only solution.
To stop your mattress from squeaking, try tightening the screws and bolts on your bed frame, placing a piece of plywood between the mattress and the frame, or using a mattress pad or topper for extra cushioning and support.
A full sized mattress is 54" x 75". If you want an edge around the mattress (for example, if you are making a platform style bed) then figure out the edge you want and calculate accordingly. I always use a piece cut exactly to the mattress measurements, and that works fine for me.
If your mattress is too soft, you can try adding a firmer mattress topper or placing a piece of plywood underneath for extra support. You can also consider replacing your mattress with a firmer one that better suits your comfort preferences.
Using plywood instead of a box spring for a bed frame can provide a more stable and even support for the mattress, reducing sagging and extending the lifespan of the mattress. Additionally, plywood is often more affordable and versatile than a traditional box spring, allowing for customization and easier transportation.
It goes under the mattress pad
I have been dealing with beds for 10 years. A mattress pad should go over the pad and under the sheets if you want to preserve it.
To create a DIY box spring for your bed, you can use plywood or wooden slats to build a sturdy base that provides support for your mattress. Measure the dimensions of your bed frame and cut the plywood or slats to fit. Secure the pieces together using screws or brackets, and place a fabric cover over the top to create a finished look. This homemade box spring will help distribute weight evenly and extend the life of your mattress.
The mattress pad is meant to be placed on top of the mattress and directly under the bottom sheet.
Generally, plywood.
