Flaxby Master’s Guild 8150 Pocket Sprung Mattress – Ultimate Natural Support with Seasonal Comfort
The Flaxby Master’s Guild 8150 Pocket Sprung Mattress represents the pinnacle of sustainable mattress design. Handcrafted in the UK, it combines advanced, glue-free spring technology with luxurious natural fibres to deliver firm to very firm support, exceptional breathability, and long-term durability—without foam or chemical treatments.
If you’re looking for a slightly softer alternative with a pillow top, explore the Flaxby Master’s Guild 4450 Pillow Top Mattress for added surface comfort with the same natural benefits.
Recyclable Cortec™ Springs for Cleaner, Fresher Sleep
At the core of the mattress lies the Cortec™ Quad Core pocket spring system, the world’s first 100% recyclable, glue-free and FR chemical-free spring technology. Each spring works independently to adapt to your movements, offering precise support while minimising partner disturbance.
Supporting the main spring unit are Posturfil pocket springs and DNAir micro springs, which respond instantly to pressure for targeted relief across key areas such as the shoulders, hips, and lower back—without the use of foam.
Natural Fibres for Intelligent Temperature Regulation
Layers of certified British wool, hemp, flax, and cotton create a breathable, moisture-wicking sleep environment. Thanks to its dual-sided design, the mattress adapts naturally to the seasons:
-
Summer side: Cooling cotton and breathable fibres help wick away moisture and keep you fresh
-
Winter side: British wool provides natural insulation for cosy warmth
These fibres are naturally hypoallergenic, durable, and expertly chosen to regulate temperature throughout the night.
Built to Last with Traditional Craftsmanship
Finished with traditional hand tufting and two rows of side stitching, the mattress maintains its structure and performance over time. The firm sleep surface keeps fillings securely in place, while the supportive base fabric enhances long-term strength.
Lovingly handcrafted by Harrison Spinks, this premium mattress showcases the quality and sustainability of the Flaxbycollection—backed by a 7-year guarantee and 100-night comfort trial.
