Frequently Asked Questions

Can I put a spring mattress on a slatted frame?

Yes. Ensure the slats are rigid and spaced no more than 7 cm apart so the internal springs receive uniform support across the entire base.

What weight rating should I choose for daily use?

For main bedrooms used every night, select a mattress with a minimum weight rating of 110 kg to 130 kg per side to guarantee long-term durability.
