Hi Lorraine.

Under specification of this particular mattress the following guidance is given; "Silentnight Real Bedstead.

Ideal for slatted bed frames but perfectly suitable for divan bases too." From this I would take it as being Yes it is suitable for slatted bedframes.

Personally, I would be inclined to bridge the slats as described above just to create a more even surface. With this mattress being a foam mattress, it may have the tendency to form around the humps on the spring slats.

I would however highly recommend the use of toppers [Read Here] - particularly on a teen boys bed where it is being used as seating as well as sleeping plus it will improve the comfort level of the mattress.

Kind regards Julie
