This Pocket Sprung Mattress is British-made and offers the best support and comfort to ensure natural sleep posture, as well as ventilation and hygiene benefits. With superior dent-resistant nursery foam, each spring is sewn with its self-contained micro pocket, allowing each spring to move freely to the contours of the precise sleep position. The mattress core is encased in a stocking net with an adjustable waterproof membrane on top, for any required position i.e. the feet to foot. The mattress has a removable fully bound and quilted cover that incorporates a side zip, allowing easy removal for washing. The cover is made of baby-tech fabric, which is specially developed, hypoallergenic, water-resistant with a wipe-clean surface, fully breathable, and washable at 60 degrees. No PVC is used for this baby and nursery mattress. The mattress complies with BS1877 part 10 for safety and performance and is BS7177 (low hazard).
