SICO Roommaker can lift more weight than any other Murphy Bed manufacturer - I know of! The trick to balancing the SICO Roommaker to float and hold positions is to have the weight of mattress and bedface already on bed. This was not possible for the NYC order because the latex mattress manufactured in California didn't stop in Denver on it's way to New York. So I called the California manufacture and asked, "How much did that king mattress weigh?" A really heavy 156 pounds! That's a two man lift of the mattress only. What we are showing in this picture is lead weights clamped to the custom made foundation that equaled 156 pounds. Mike is pleased that the bed is holding all positions and floating to the floor with minimal effort. Lifting the bed was a two finger operation. I challenge any other manufacturer to match this controlled lift and lowering. We have three pages devoted to the explanation of how the SICO Roommaker works.
