Curved slats are damaging my mattress, help!

Cole asked
4th March 2014

I have a set of sprung bed slats for my king bed. I purchases a plush mattress and felt it was dipping very slightly in the middle already. I believe this is from the curved bed slats not flattening out when I sleep on it. It gets worse when sleeping with my partner, I tend to be pulled towards the middle of the bed. Would it be better to return the slats and purchase flat slats?

Or keep the curved slats and layer a peice of plywood over that extends to the top of each arch as shown in your picture?

I heard that the curved bed slats are better and more durable and will prolong the life of the mattress. Also if the playwood route is the best, what thickness of plywood is reasonable?

I am 180lbs and my partner is 145lbs. Thanks >

Hi Cole,

I would recommend boarding over the slats to reduce the impact of sagging you’ve experienced.

This occurs when mattress moulds to the gaps in between slats on a base.

It then can cause sagging and uneven wear to the bed.

We have discussed this in depth and how to board over slats shown here.

I’ve never heard of sprung slats or any slats increasing the life of a mattress.

What does help keep a mattress in good shape is a consistent bed base ie whether it be a divan or otherwise, and regular mattress turning and rotation.

 

As for the thickness of plywood, 4mm should be enough, it’s only to even out the pressure of the mattress on the slats so there are no gaps for the mattress to be forced through.

 

If you have any further questions please don’t hesitate to contact the office on 0161 437 4419

We hope that helps!
