Product description

Product code: 80020814

The John Lewis British Natural Collection is crafted by renowned heritage bedmakers Harrison Spinks. Designed and made in-house in Yorkshire, the Wool 5750 features layers of natural fillings including traceable British wool, homegrown hemp fibres and award-winning spring technology. This mattress has a soft feel but can be ordered in a regular or firmer tension, depending on comfort needs.

Using only premium fleeces, the luxurious British wool in the 5750 range is soft to the touch and expertly woven. Thanks to wool's natural heat and moisture-regulating properties, this unique mattress fabric helps keep you cool and comfortable all night long.

Cortec™ Quad pocket spring system
This glue-free support system has been designed, developed and manufactured in-house, with a design that unites comfort and sustainability. 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.

Eco-friendly design
Marking a huge and sustainable 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 responsibly 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. For more information, call 03452 661 805 and we can tell you where the range you’d like to view is on display.
