Mattress materials
FABRIC
Quilted in soft and durable Poly Jacquard cover with the
competitive edge. And it is safe because it uses eco-friendly certified fabric.
MEMORY FOAM
We use memory foam that has been tested tens of thousands of times to find the optimal body pressure distribution conditions. Each memory foam layer has an optimized composition for body support.
GrandRest mattress provides soft comfort with soft elasticity and recovery that support the body's curves.
POCKETED SPRINGS
GrandRest uses iCoil pocket springs.
iCoil pocket springs can move independently to provide better support and conform to your body shape. This can reduce pressure points and improve comfort. Because each spring is separate, motion transfer is reduced, making it a great choice for couples who don't want to disturb each other's sleep. Finally, pocket springs are more durable because they are less likely to break over time.
