Hi Sandra,
Many thanks for your question about bed frames and mattresses.

A solid top bedframe or platform top divan will firm up the feel of any mattress. But it is only marginal. It's not going to take the comfort of a medium feel mattress in a firm or down to a soft. It's subtle but can help make the difference if a mattress is feeling slightly too forgiving in the top comfort layer.

Don't forget that a mattresses spring unit is purely based on your bodyweight. It does not relate to the overall feel of the mattress which is created by the upholstery layers also known as mattress comfort layers.

Likewise, if your mattress is feeling slightly too firm on a platform top divan or bedframe, then a sprung edge divan can soften it slightly to perfect the feel.

The one thing that mattress and bed retailers don't want you to know is that all mattresses are suitable for all bases. Some of the bases may need a slight tweak, like boarding over slats for a more consistent sleep surface. But essentially all quality mattresses are suitable for all stable well-made bases.

Don't be fooled by thinking certain mattresses need a bedstead or a special sprung divan. It's just marketing to flog you a new base along with your mattress.

If your bed base is in good condition without any damage then it should be fine to keep it. Change if for aesthetic reasons or to soften/firm up the mattress, but never because you think you have to.

If you have a slatted bed base you can read on how you can board over the slats to prevent them from damaging your mattress.

The video below will help you understand the confusion and difference between solid and sprung slatted bases.

We hope that helps and gives you further mattress buying guidance. If you have any more mattress related questions please get back in touch on info@localhost or 0161 437 4419.

Sleep well
