8. FAQ

Is this product suitable for people with back pain?Yes. With a good mattress, the Ashdown bed base provides uniform support that limits pressure points.
Can it be tested or returned?Yes. You have a 200-night trial. Returns are free.
What is its average lifespan?Between 10 and 15 years depending on use and maintenance.
Are tools needed for assembly?No. Assembly is done by interlocking, without screws or screwdrivers.
What types of mattresses are compatible with the Ashdown bed base?

The Ashdown bed base with flexible slats is compatible with the vast majority of modern mattresses: memory foam, natural or synthetic latex, hybrid mattresses (pocket springs + foam), and traditional foam mattresses. Its ventilated structure with spaced slats is particularly recommended for mattresses requiring good ventilation. However, traditional Bonnell spring mattresses (like "old continuous springs") may not be optimal, as they require a rigid slat bed base. Simba naturally recommends its own hybrid mattresses for an ideal pairing.
