Spine-Lab Mattress 5 Zone 21cm Medium Firm Foam Bonnell Spring – Queen – White

Sleep smarter with a mattress that blends traditional Bonnell spring support with modern comfort foams. The Spine-Lab 5-Zone Bonnell Spring Mattress is built to cradle your body where you need it most, while keeping you cool and comfortable all night long.

What makes it unique

• 5-zone Bonnell spring core: precision-engineered zones provide targeted support and alignment, promoting proper spinal posture while redistributing pressure across the hips, shoulders, back, and legs.
• Upper memory foam layer: adapts to body contours for personalized support, enhancing comfort without sacrificing stability.
• Breathable, cool-touch quilted cover: designed to prevent heat buildup, helping you stay comfortable through warmer nights or restless periods.
• High-density foam layers beneath the surface: reinforce durability and long-lasting support, so the mattress holds its shape over time.
• Hypoallergenic materials: a sleep surface suited for sensitive sleepers, contributing to a cleaner, healthier night’s rest.
• Medium-firm feel: versatile enough for a range of sleepers, from back to some side sleepers, providing a stable yet comfortable surface.
• Queen size: 153 cm x 203 cm x 21 cm: ample, balanced dimensions that pair well with a wide range of bed frames.

Practical benefits and use cases

If you sleep with partner or move frequently at night, the combination of a firm Bonnell core and contouring upper foam offers a dependable base with responsive comfort.

• Back sleepers who need steady support and spinal alignment
• Most side sleepers seeking targeted relief at shoulders and hips

• Couples who want a balanced blend of support and comfort with minimal motion transfer
