Good day, I bought a 3/4 Executive Spine Three Quater Mattress Bed Set Extended leght, that take a weight of 200kg. The day after delivery I complaint about the quality that is not good etc. Now not even a year after I bought the bed set it is giving me problems, and cannot take a weight of +_135kg, it us supose to take 200kg. I informed Sleep Monk of the problems with the bed set and now they just ignors me.
