How to stop a bed bowing in the middle?

Rob asked

25th October 2012

I have a double slatted bed with a memory foam mattress. Neither were cheap but something is not right; the mattress bows in the middle because of the dip in the slats. I have to put pillows in the dip to equal it out but that is obviously not ideal. Reading above it sounds like a pad is the answer but I can’t find any for the base of the bed that would seem rigid enough to level it out. Do you have any pointers of what I should be looking for?

Thanks .

Hi Rob.

This is the hump back bridge effect.

The weight of your mattress is not substantial enough to compress the slats, so the rigid central support bar on your frame will become the dip.

An easy and economical solution is to lay a couple of MDF sheets across the slats (side to side) bridging the central support bar to form a flat even surface for your mattress.

I would also add an old duvet to act as a cushion so that your mattress is not sitting directly on the MDF (there may not be enough ventilation).

Hope this helps and let us know if this solves the problem.

Thanks for your help to my query on the hump back bridge effect.

I did get some think board and laid it across.

It’s definitely made a difference, can tell the base is now flat.

The mattress still sinks in the middle though!

I think this because it’s a memory foam and I’m not used to them.

Might go backed to springs!

Hi again Rob.

Try this out.

Lay the mattress directly on the floor and see if the dip is still there.
