Cabinets -Build In Flex?

Still trying to decide if I should build cabinets so they float around somewhat -

putting folding counter top at 29 to 30 inches above floor-
to have strength area in correct place - ended up having to use a 2x4
along a 4 foot section of wall behind driver
and a 7 foot section on slider side -
this was the only way I could get wall paneling even and have strength at correct location
for folding Table tops -

glad to hear that --

I did have some squeaks between wood and metal -
had an idea something like that might happen -
found very early -

I put a thin sheet of polyester matt between wood and metal-
seems to have worked - may use in other locations -

I think this cloth is called Batting -found at cloth store - 1/2 thick -

similar to thinsulate type fluff -
