I’m stuck with two box springs that are 90cm wide, 200cm long. I need them to fully support a mattress that is 190cm wide, 200cm long. My thought is to attach two 1.8 cm wide, 200 cm long boards to each box spring. My question is what’s the best way. I could somehow attach all 4 boards together and place them between the box springs. I have a board underneath that can support all that, even if they aren’t attached. Another way is to attach two boards to each box spring. For aesthetic reasons, I would attach all the boards on the inside, not one each on each side. The question is how - glue? Bolt and nut? Another idea is a way I haven’t thought of but you have. With the tools I have, the first two ideas are the most workable. Thanks in advance for your help.

Forget trying to attach boards to the box springs. Just buy a sheet of 1/2" or 3/4" plywood and lay it on top of the box springs, with a 10 cm gap between the box springs. The weight of the mattress will hold the plywood in place, but if you're worried about it a few screws through the plywood into the box springs will lock everything in place. If you lack the tools to cut the plywood to size, any home center will be happy to cut it for you.
