Spine-Lab 5 Zone Bonnell Spring Mattress 21cm Medium Firm Single

The Spine-Lab 5-Zone Bonnell Spring Mattress is a medium-firm sleeping surface with a 21cm profile, built from hypo-allergenic materials and traditional bonnell spring construction layered with high-density foam. Its 5-zone configuration redistributes pressure across key body zones while the upper memory foam layer moulds to your body for a personalised sleep surface. A cool-touch quilted cover reduces heat build-up, keeping the sleep environment comfortable through the night. Available in Single, Double, Queen, and King sizes at a consistent 21cm depth.

Wake up on a surface that held you in the right position all night — the medium-firm feel is neither too soft to sink into nor too stiff to leave you uncomfortable. The bonnell spring layer provides that reliable, responsive base that many sleepers find easier to move on compared to full foam alternatives.

Spine-Lab's hypo-allergenic construction makes this a smart choice for allergy-sensitive households, while the durable spring core ensures long-lasting shape retention. It's a straightforward, well-built mattress that delivers night after night without demanding attention.
