How ya doing son? let me tell you something, i designed my own one not 3 weeks ago, so i am the bloke to see. first of all it had to be excatly right for me, so careful measurements all round ,knee space, elbow leaning bits, ashtray built in, spot to keep can of special brew, and little shelf on the side to put the rest of cans. now mines 3ft high, and i put a 4 aaand a half ft long top on it, but obviously they fold down so you only have about over ft and a half. know what i mean? and it had to have wheels and a top that angles to get max comfort. in factthen i kitted it out with go fast stripes and sun visor.in fact i can be pushed along in my spinning chair with my table laptop in front speakers each side, cans,roll ups,biscuits and white powder all within reach,and im going to fix a tube to run waste into a bottle for those all weekend sessions that i like.
