Frequently Asked Questions About Foam Mattresses

Can you use a high-density foam mattress on a slatted bed base?

Yes. High-density foam mattresses work exceptionally well on slatted bases. Ensure the slats are rigid and spaced no more than 7cm apart to prevent the foam from pushing through the gaps over time.

Is a foam mattress better than a spring mattress for single sleepers?

Foam mattresses offer distinct advantages over spring mattresses, including silent performance, zero coil pressure on your joints, and superior durability against sagging, making them an ideal choice for single and double sleepers alike.
