The FAT Medium Firm Bonnell Spring mattress is a versatile everyday mattress designed for comfort and durability. Built with a premium 2 Sealed Border design, 16cm robust spring system, and a breathable knitted surface, it delivers reliable support while maintaining a neat, tailored look that lasts.
If the firm option feels too hard, this Medium Firm variant offers the ideal “Goldilocks” balance. It provides the dependable support of traditional springs with a slightly softer, more forgiving tight top layer, ensuring comfortable, restorative sleep night after night.
