The Memory Ortho Box Pillow Top Mattress is expertly designed to provide the ideal medium to firm feel, perfect for those who want a balance of plush comfort and solid support. The mattress features a 25mm memory foam layer that conforms to the body, offering pressure relief and promoting healthy spinal alignment while still maintaining a supportive, firmer feel ideal for back and side sleepers. At its core, the 12.5g orthopaedic sleep system uses durable bonnel open coil springs arranged in rows, connected by spiral helical wires to provide consistent support and prevent sagging. The combination of these springs with the memory foam layer offers a balanced support system, giving you the stability and pressure relief your body needs for a restorative sleep. The mattress is finished with a luxurious stretch knit cover, providing a soft and breathable surface that enhances comfort while regulating temperature. The hand-tufted construction ensures long-lasting durability, preventing the fillings from shifting. Air vents are placed strategically to encourage airflow, keeping the mattress fresh and cool throughout the night. Plus, handles make rotating the mattress easy to maintain its shape and ensure even wear. The Memory Ortho Box Pillow Top Mattress is the perfect solution for sleepers who want a mattress that combines comfort, support, and durability with a medium to firm feel that promotes healthy, restful sleep.
