Mysa Glacier Mattress

The Glacier is a hybrid mattress combining a 5-zone pocket spring system, ergonomic microcoils, and graphite-cooled foam layers. It's our highest-spec mattress - six layers engineered for adaptive support, pressure relief, and advanced cooling. GoodHomes Approved.

• 5-zone pocket spring system - individually pocketed springs that adapt independently to your movements
• Microcoil® ergonomic support layer - smaller open coil springs for an even closer level of targeted pressure relief and breathability
• AeroSpheric HR-GX® graphite-infused foam - two times more cooling than standard graphite foam
• AeroSync HR-GX® multi-zoned comfort foam for personalised cushioning at every point of contact
• BeFree® 3D mesh cover - 40% more breathable than standard knits, machine-washable at 40°C
• Hypoallergenic, vegan-friendly, and made in Manchester

The Glacier has a medium-firm feel - adaptive enough to contour to your body, supportive enough to keep your spine aligned. The combination of pocket springs and foam gives it a responsive, cradling feel that pure foam mattresses can't replicate.

• Medium-firm - supportive with enough give to relieve pressure at the shoulders and hips
• Adaptive - the 5-zone pocket spring system adjusts independently to different parts of your body, providing firmer support where you're heaviest and softer cushioning where you need relief
• Responsive - microcoils and pocket springs react to your movements, so the mattress adapts as you shift position through the night
• Reduced motion transfer - individually pocketed springs move independently, so your partner's movements are absorbed rather than transferred
• Best for: side sleepers, back sleepers, couples, heavier builds, and anyone who wants adaptive support that responds to their body

From top to bottom:

• BeFree® 3D mesh knit cover - breathable, removable cover that's 40% more breathable than standard knits of the same weight, promoting maximum airflow and reducing heat build-up. Machine-washable at 40°C.
• AeroSpheric HR-GX® graphite-infused foam - open-cell foam infused with graphite spheres for advanced cooling, delivering twice as much cooling as regular graphite foam. Moulds to your body shape to regulate temperature and wick away excess moisture.
• Microcoil® ergonomic support layer - individual small open coil springs that conform to your body, providing an even closer level of targeted pressure relief. Highly breathable for enhanced airflow throughout the mattress.
• AeroSync HR-GX® multi-zoned comfort foam - high-resilience polyurethane foam that contours to your body's shape across multiple pressure zones, reducing pressure points for personalised, weightless-feeling cushioning.
• 5-zone pocket spring system - individually pocketed springs that adapt independently to your movements, targeting orthopaedic-style support to key areas of your body and promoting neutral spinal alignment.
• Firm foam base layer - high-density foam foundation providing unwavering structural support beneath the spring system.

All foams are hypoallergenic and manufactured in our Manchester factory.
