Problems solved by technology

There are also several sofas installed on the yacht for people to rest, and the surface of the sofa used on the yacht usually uses leather or PU leather sofa covers. Compared with leather sofa covers, PU leather sofa covers are more durable. The production and use costs will be significantly reduced, and the waterproof effect is good, but the wear resistance of the traditional PU leather sofa cover is far inferior to that of the leather sofa cover, and the sofa cover used on the yacht is used in a humid environment for a long time. PU leather is prone to mildew and breeds a large number of bacteria, which is not easy for health and later maintenance of sofa covers
