Tips for customizing mattresses

Mind the bed frame model before measuring and customizing your mattress!

Is the building too narrow to deliver?

Most of SINOMAX's mattresses are eligible for rolled delivery, and the vacuum compression technology will never destroy the structure of the memory foam, maintaining the best quality. There is no need to worry about narrow lift/staircase/doorway! At the same time, its become more efficicent in transportation, which also reduces carbon emissions.

Boxed delivery is also available for certain mattress models and sizes, which strengthen the protection of the mattress.
