Which star hotels use spring mattresses?

It is suggested that the landlord can refer to Debao's mattress. I think Debao is the best choice! Debao's unique three-zone spring system supports your body most closely, and the springs near the hip joint are more tolerant than those in other areas. The opening design of the spring ensures that there is no edge depression or coil protrusion between the three areas. The middle of pocket springs in the three-zone pocket spring system is connected by non-woven fabrics, so that each spring can run independently. The system can increase the elastic stress points to the maximum extent and has extremely high bearing capacity. High-quality sponge frame support system, high-density foam tightly surrounds the edge of the mattress, effectively increasing the sleeping area of the mattress, so that even if you sleep on the edge of the mattress, you will not feel slipping, avoiding the deformation and depression of the edge caused by long-term use. Ridge-protecting steel pole, in which a solid steel pole is added in the design, is designed to give more solid support when the part bears heavy weight pressure.
