John Lewis & Partners Natural Collection Silk 19400, Super King Size, Firm Tension Pocket Spring Zip Link Mattress

Our Natural Collection has been upgraded and reinvented to provide even better comfort, whilst being our most sustainable range yet. Fully recyclable at its end of life thanks to a completely glue-free design, the Silk models have a total of 19,400 springs in the king size and provide pressure-relieving, responsive support. This zip link model can be used as one large mattress or as two independent mattresses, depending on your needs. About Ortho Support The Silk models fit into our Ortho Support range. These are reassuringly dense and supportive, perfect for those who prefer a firmer feel. Natural fillings This mattress is upholstered with layers of insulating wool and breathable hemp and cotton to maintain a natural airflow throughout the night. Natural fillings are durable and highly absorbent, helping to keep your sleep environment fresh-feeling and hygienic, and silk is especially strong and hardwearing. Manufactured in Yorkshire by Harrison Spinks, more than 50% of the fillings in each mattress are sourced and grown from a local farm, and all fibres are made into fillings in the UK to ensure responsible manufacturing. Cortec™ pocket spring system The high density pocket springs in this support system are produced in a smaller, finer and more tightly coiled format and distributed to provide more individual points of contact with the body. This ensures greater contour accuracy, keeping your body weight evenly distributed and reducing pressure points with precision. Cortec springs are also lighter than conventional springs, so work alongside the natural fillings to ensure better ventilation each night. The Cortec pocket spring system was awarded Component of the Year at the 2019 NBF Bed Show. Sustainable comfort technology Marking a sustainable step forward, the Cortec springs are individually pocketed and sealed with heat, rather than glue. This makes the mattress 100% recyclable at the end of its life, as each spring can be simply disassembled and reinvented in the future, ensuring zero waste to landfill. We guarantee to recycle your mattress responsibly when you're ready to buy your next one, after seven years. Visit us in store or call 03456 049 049 and we will help you to choose a new mattress and recycle this one, so that you can sleep even better knowing you are doing the right thing for the environment. Chemical free sleep surface Traditionally, manufacturers have added chemicals to mattress fabrics in order for them to be fire retardant and compliant with regulations. In our quest to be as natural as possible, this mattress has a naturally fire retardant cover that is free from chemical treatment. 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.
