Hi Jenny,

Thanks for your question.

Ideally the best base for a memory foam, hybrid foam or latex mattress is a platform top divan or platform top alternative.

This is because foam will start to take the shape of the surface it is placed on so it you have a slatted base then you run the risk of the foam conforming to the slats and spaces in between. Please see the article here for further information on mattresses for slats.

This leads to lumps and what looks like sagging.

I very much doubt the Tempur cloud will have sagged in two weeks, that said I'd try to board over the slats and if the problem still occurs get back in touch with Dreams.

I hope this has answered your questions fully but if you do have any further queries please don't hesitate to contact our office on 0161 437 4419.

Kind Regards, Lee.
