Review on Enhance Your Furniture with Sauton's Folding Lift Up Top Table Mechanism Hardware Fitting Hinge: Gas Hydraulic Lift Up Table Mechanism (1 Pair) by Casey Vance

This was a great solution for raising and extending my propane stove/grill to a comfortable working height while still being able to tuck neatly under the bench. It is best suited for heavy, fixed furniture. The pneumatics are powerful, so it's a bit tricky to get them down. Also, whatever you're lifting needs to have enough weight to support it, otherwise it could open from its stowed position if you look at it from the wrong direction. Designed to be mounted on vertical sides rather than a horizontal surface, but I eventually found some 3/4" corner mounts that kept the profile low enough to fit under a bench.
