Silentnight Miracoil Pillowtop Mattress - Kingsize (150x200cm, Firm)

Silentnight Miracoil Pillowtop Mattress - Kingsize (150x200cm, Firm)

The Silentnight Miracoil Pillowtop Mattress is a kingsize bed base designed to provide structured support and enhanced comfort through specialised spring technology. It incorporates Silentnight's proprietary Miracoil spring system, which features a continuous, zoned arrangement of 768 coils. This design is engineered to offer differentiated support across the body, aiming to promote better spinal alignment and posture during sleep. The mattress is finished with a sustainably made Eco Comfort pillowtop layer, which adds a plush surface while promoting airflow for a cooler sleeping environment. Key features include a firm feel profile, making it suitable for those who prefer or require substantial support. The construction is single-sided, meaning it should not be turned over but rotated head-to-foot periodically for even wear. The micro-quilt finish on the pillowtop adds to the tactile comfort, and the 'no roll together' design helps prevent partners from rolling towards the centre of the bed. The mattress is manufactured in the UK and arrives delivered in a single package. This mattress is well-suited for individuals or couples seeking a firm, supportive sleep surface with targeted zoning. The Miracoil system aims to distribute weight evenly, which can be beneficial for people of varying builds. The breathable pillowtop makes it a practical choice for those who sleep warm. Its durable construction, backed by a 5-year manufacturer's guarantee, positions it as a long-term investment for the bedroom, offering a balance of technological support and everyday comfort.
