The Lux Royal model is the last creation by Regnogrande in terms of comfort and innovation. The mattress is composed of a removable and detachable topper in Memory Air Fresh, the last generation viscoelastic and contains micro-particles of gel that promote blood circulation and thermoregulation. The topper is proposed in combination with a plate in Soia Foam divided into three layers with inside two layers with 3000 independent micro-springs of 4cm in height. The micro-springs ensure a highly stretchable and progressive comfort throughout the mattress, working in symbiosis with the three plates shaped in the differentiated enclosing areas. The Lux Royal model is available in two different kinds of lift : soft and firm.
