The Arlen mattress is a timeless investment in restorative sleep, whatever the weather brings. Locally sourced British wool regulates temperature beautifully, keeping you comfortably cool in summer and wonderfully warm in winter. Highly breathable kapok offers featherlight cushioning with a silky, cloud-like feel. Naturally moisture-wicking and hypoallergenic, kapok is entirely plant-based and offers enhanced airflow, owing to its ultra-light and fluffy texture. It's blended with luxurious silk and mohair in the sumptuous Arlen mattress. A responsive layer of individually wrapped pocket springs evenly distributes body weight for full-body support, helping to ease pressure and promote restful alignment. Deep traditional tufts secure the sumptuous fillings in place for lasting resilience, with a soft and comforting damask surface. The Arlen is double-sided and can be refreshed with a simple flip of the mattress, offering enhanced durability. 11,300 individually wrapped pocket springs Medium tension offers adaptive support, ideal for front, back or side sleepers Available in sizes single to super king 1-year guarantee Enjoy peace of mind with our 100-night comfort promise – if it’s not perfect, we’ll exchange it Made in the UK exclusively for Feather & Black Inside the mattress Thousands of pocket springs adjust to your body without disturbing your sleep partner’s slumber Micro pocket springs react to the slightest movement, keeping you supported Innovative Platinum 3D(TM) polyester is fully recyclable at the end of its life Luxurious blend of natural wool, mohair, silk and kapok Soft and lustrous kapok is exceptionally durable, naturally hypoallergenic, highly breathable, moisture-wicking and flexible Mattress finishing Wrapped in soft-touch damask fabric Expertly machine stitched for longevity Traditionally tufted sleep surface holds fillings in place Looking after your mattress Double-sided: Flip this mattress regularly for lasting support Rotate head to toe and flip over weekly for the first three months, then just once a month
