I bought this to support my Laptop,a compromise between very expensive options and the cheaper flimsy items commonly available in the UK.
It comes as a flat-pack with a spanner and screwdriver to assemble.It's very robust and solid when assembled and it's in a mainly stove enameled tubular steel finish, smooth and grey with black fittings.
The instructions are in German, but it has pictures making assembly straight forward.
The unit has optional feet or casters,feet are commonly used to fit under furniture. I like the casters for my lounge chair and
the casters also have locking tabs.
The perforated top is fine for laptop airflow and cooling. There are optional padded bars to fit to prevent items slipping off
the tray. There's an adjusting screw for height and one for vertical tilt. the top swivewls around the column. There's also two adjusting screws for horizontal tilt so you can tilt the a laptop keyboard for easier use.
I'm very happy with this item, it looks cool and modern and does everything I want it to do.
