Bonnel spring mattress Trevi is composed of a spring system of 300 springs (for the double version) which gives it a medium capacity. Thanks to the water-foamed layers on both sides, the mattress is soft and comfortable, guaranteeing a reliable and comfortable response to the stress given by the weight of the body. Two sheets of rigid felt wrap around the spring to isolate it from the rest of the structure.
Mattress with fixed cover (not removable) in fabric with side band embroidered with the application of aerators for complete breathability and fabric handles to facilitate movement.
