Our resonance tables can be made with fixed or folding legs, with a tilt or a fixed top.  The height of the table can be specifically requested. I am currently making tables at two heights.The height is measured from the ground to the underside of the table. The folding leg tables can come with two sets of legs. One for a height of 185 mm and the other for a table of 220mm.They are fitted by simply undoing the 4 butterfly nuts. This makes for a much more stable table. The fixed top table with fixed legs is $80.00. The flip/slope top table with two sets of folding  legs is $145.00 and with one set of folding leg  is $130.00. The adjustable height tables commonly used now in various VRCs  are 220mm high with the legs extended and 180mm with them at their shortest.
