About it
IKEA's straightforward open coil mattress. IKEA notes that Bonnell springs can transfer motion, so it is better suited to one sleeper — a single bed, guest bed or child's room.
Key features from the maker
- Bonnell springs with a foam layer and wadded cover
- 17cm deep
- Roll-packed — IKEA allows about 72 hours to regain shape
- IKEA states it meets BS 7177 flammability requirements
