Enjoy firmer support and luxurious comfort with the Wentworth Mercer Deluxe Wool 4000 Pocket Mattress. Crafted using traditional techniques and premium materials, this mattress delivers dependable support and pressure-relieving comfort night after night.At the centre of the mattress are 4000 individually pocketed springs that react independently to your body shape and movement. This responsive spring system evenly distributes weight while helping to relieve pressure around key areas such as the back, hips and shoulders. The independent spring movement also helps minimise motion transfer for a more peaceful sleep.The steel springs are twice tempered to improve durability and enhance long-lasting bounce-back support. This helps the mattress maintain its supportive feel and structure over time while promoting a more restorative sleep experience.Layers of natural wool fillings create a warm yet breathable sleeping environment. Wool naturally regulates temperature to help keep you comfortable throughout the seasons, while soft synthetic comfort layers improve airflow and add extra cushioning for a fresher feel.A sturdy rod edge support system reinforces the perimeter of the mattress, maximising the sleeping area and reducing roll-off sensation. Two rows of traditional hand side-stitching further strengthen the mattress border for enhanced durability and edge-to-edge support.Finished with a classic tufted surface and wrapped in a soft viscose cover, the mattress maintains its shape and luxurious feel over time while securing the fillings neatly in place.Designed as a double-sided mattress, regular turning and rotating help extend its lifespan and maintain comfort. Handcrafted in the UK and backed by a 5 Year Guarantee plus an additional 5 Year Warranty, the Wentworth Mercer Deluxe Wool 4000 Pocket Mattress offers reliable support and lasting quality.
