"Designed to balance responsive support with gentle cushioning, the eXtreme Comfort Mars Black Border Hybrid Mattress combines an open coil sprung core with a high-density visco-elastic memory foam layer. With a medium to soft feel, it offers pressure relief and body contouring for a more comfortable night’s sleep, whether it’s used every day or kept ready for guests. Finished with a Stress-Free Flat Top fabric cover and a contrasting black micro-quilted border, the surface feels soft while promoting airflow for a fresher sleep environment. Made in the UK and certified to meet UK fire safety regulations (BS 7177:2008 Domestic Use), it’s a considered choice for bedrooms where dependable comfort and straightforward practicality matter. For easier handling, the mattress is compressed, vacuum-packed, rolled, and boxed; simply unbox and allow several hours to expand in a ventilated room before use.
