Get a mattress cover that has an elastic bottom that will fit under the encased mattress while covering the top and around the sides of the mattress encasing. Comfortable mattress covers are available in regular and waterproof styles. The mattress encasing will protect the mattress from leaching dust dust mite and pet dander allergen. The mattress cover will protect the mattress encasing from becoming contaminated with fresh dust dust mite and pet dander allergen. Waterproof mattress covers will also protect your mattress encasing from urine and liquid spills. The mattress cover will put a comfortable barrier between your encased mattress and sheets while extending the time and need to clean the mattress encasing that is being protected under the mattress cover.
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.
