The Irwell Pocket Natural mattress from Simply Prestige is a premium hand-crafted design that blends supportive pocket springs with luxurious natural fillings for a deeply comfortable and breathable night's sleep. Made in the UK with exceptional attention to detail, this mattress combines 1000 pocket springs, layers of wool, silk, cashmere and cotton, alongside a knitted fabric cover infused with Tencel fibres to create a high-quality and naturally temperature-regulating sleep environment.

At the centre of the Irwell Pocket Natural is a 1000 pocket spring system. Each spring is individually enclosed in fabric, allowing it to move independently and contour precisely to the body’s natural shape. This promotes excellent spinal alignment, reduces pressure on key areas and minimises partner disturbance by limiting motion transfer. The result is a supportive and responsive feel tailored to the sleeper’s movements.

The mattress’s comfort layers feature a carefully selected blend of wool, silk, cashmere and cotton. These natural fillings offer breathability, moisture-wicking properties and a soft, sumptuous feel. Wool acts as a natural temperature regulator, helping you stay warm in winter and cool in summer. Silk and cashmere add luxurious softness, while cotton enhances airflow and ensures a fresh and hygienic sleeping surface. Together, these layers provide outstanding comfort while maintaining the mattress’s long-lasting structure.

The Irwell Pocket Natural is finished with a high-quality knitted fabric containing Tencel fibres. Tencel is known for its exceptional softness and moisture-management capabilities, creating a smooth, breathable and hygienic sleep surface that complements the natural fillings beneath.

Deep hand tufts secure all internal layers in place, preventing movement and extending the lifespan of the mattress. Flexi Edge Support reinforces the outside edges, maximising the usable sleeping area and reducing roll-off. This also helps the mattress maintain its shape over time.

Designed as a reversible mattress, the Irwell Pocket Natural should be turned regularly to ensure even settlement of the fillings and prolong its durability. Care icons advise not to bend or fold the mattress and to rotate as needed for best results.

Hand crafted in the UK and compliant with UK fire safety standards, the mattress also includes a reassuring 5-year warranty, supporting long-term peace of mind.
