Construction

For construction detail, start with the IKEA brand hub or our mattress types guide, which explains how foam, latex, hybrid, and innerspring builds differ in feel and durability.
IKEA signature technology
- 365-Day Return Window: A full year to exchange or return a mattress — the longest trial in the budget tier, and longer than most DTC brands.
- Washable Zip Covers: Most IKEA mattresses ship with a removable, machine-washable cover, which is rare below $500.
- Slatted Base Pairing: The range is designed around IKEA's own Luröy and Lönset slatted bases, which change the effective firmness of the mattress on top.
