Box Spring / September 15, 2017 / Emmeline
More important than how long your bedding will last or how comfortable you are is the safety of purchasing new mattresses and putting them on old box springs. The risk is that the older ones may not meet flammability standards and thereby put you more at risk even if your bedding does meet the standards. If you have gone to various mattress stores and you have been encouraged at each one to purchase both bedding and box springs it is still up to you.
If all else fails then the best solution is to measure the width and length of the bed. Use these measurements and cut out a plywood deck. I would recommend cutting them into 2 or 3 smaller pieces. Cutting one large plywood deck can be difficult especially if you have a larger size like a king or queen. Once again though check with your manufacturers guide. The flat foundation could possibly make the mattress less comfortable.
Many people love platform beds because of their low profile. The bed might be comfortable for people who do not like to sit up high in their beds. Or maybe even have health issues like back and knee pain which makes it difficult for them. It just makes it easier for them to get out of bed. Unfortunately not too many people understand how to correctly put a mattress on top of a platform bed.
