The Indigo mattress combines advanced cooling technology with multi-layer comfort and targeted support. Graphite PCM Fabric helps absorb and release excess heat to maintain a balanced sleep temperature, while a breathable hollow fibre blend adds soft cushioning and moisture control. Gel Bio Foam and PE Gel Memory Foam work together to provide pressure relief, temperature regulation, and a cleaner, more hygienic sleep surface. High-density plush and medium support foams enhance comfort, durability, and body impression resistance. At the core, the 1800 CoreBalance™ 7-zone pocket coil system delivers ergonomic spinal alignment and adaptive support, while a foam edge support system maximizes the usable sleep surface and reduces motion transfer.
