John Lewis Ultimate Natural Collection 43000, King Size, Regular Tension Pocket Spring Mattress

For a night’s sleep you won’t want to end, meet Ultimate Natural Collection: our most premium range of mattresses, handmade by experts in Yorkshire from the most luxurious natural fillings that have been carefully chosen for their wonderful comfort and temperature-regulating properties. High-density, individual pocket springs, alongside a Cortec™ Quad Revolution spring system work to reduce pressure points and provide excellent targeted support. And even better, these mattresses are fully recyclable at end of life. No detail has been missed, and each mattress has been stitched by hand with five rows of stitching on the border. Handcrafted by Harrison Spinks.

Neither too soft, nor too firm, our Regular tension models provide just the right balance of support, however you sleep.

Natural fillings
Manufactured in Yorkshire, this mattress is upholstered with layers of the finest locally sourced natural fillings. Luxurious cashmere and British wool offer an indulgent feel while super-soft silk provides excellent temperature regulation. Hemp also wicks away moisture, keeping the bed fresh and hygienic, while long strands of Egyptian cotton provides extra softness. The cover is also made with insulating, luxury wool which is fully traceable to British farms. It’s naturally fire retardant and free from chemical treatment for a healthier sleep.

Cortec™ Quad Revolution pocket spring system
This glue-free support system has been designed, developed and manufactured in-house. It offers a two-stage level of support thanks to a spring-in-spring design, delivering even greater lumbar support and pressure relief. The heavier parts of your body will be perfectly supported to help maintain an aligned spine and to prevent unwanted aches and pains. Plus, as the springs work individually, air can flow better through the mattress to keep the temperature controlled. This system works alongside additional 4K and 5K high-density calico pocket springs.

Recyclable design
Marking a step forward in mattress manufacturing, the patented Cortec™ Quad springs are sealed with heat rather than glue. Not only does this mean the springs can work individually for maximum efficiency, it also means each spring can be disassembled and reinvented in the future. So this mattress is 100% recyclable at the end of its life, rather than ending up in landfill sites across the country. We guarantee to recycle your mattress when you're ready to buy your next one, after seven years. Visit one of our shops or call 03456 049 049 and we'll help you to choose a new mattress and recycle this one.

Make the most of your mattress
After unwrapping your new mattress, leave it in a well-ventilated room for a few hours. Any natural scent from the fillings will dissipate after a few days. We recommend using a cotton mattress protector and airing your mattress regularly. If you’re placing this mattress on a slatted base, ensure the gaps are no more than 7.5cm apart.

Try before you buy
This is an important purchase and it’s worthwhile to try your choice of mattress in store to make sure it's right for you. Our store Partners will be able to tell you more about its benefits, and recommend options based on your needs.
