John LewisBritish Natural Collection Grantley Ultimate 30000 Pocket Spring Mattress, King Size

Inspired by nature’s ability to comfort us, the Grantley Ultimate is an investment in true luxury that rewards you every single night. This masterclass in handmade natural comfort is finished with exclusive WoolKind™ fabric – softer, kinder and naturally fire‑retardant.

Natural fillings
Sink into eight layers of naturally breathable, body heat‑regulating fillings. Including traditional British horsehair and alpaca for elevated comfort, lambswool, traceable British wool from John Lewis selected farmers, along with homegrown linen and hemp.

Pocket springs
Six layers of Micro 4000 springs and two layers of Micro Duo™ springs create a feeling of floating on air, while the firmer mattress edge removes any feeling of rolling off. The unique Cortec™ Revolution Air adaptive spring‑in‑spring pocket system provides deep‑down, tailored support. All the spring layers are wrapped in breathable fabrics to allow fresh, healthy air to circulate into the heart of the mattress.

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.
