Sturdily built, though rather heavy as a result. It has little or no wobble and feels reassuringly solid and stable. It can move a little too easily on a hard smooth floor so if necessary try castor holders or something to keep it still; however, 'chocs away!' if it's on carpet as the carpet's "resistance" keeps it still.
Its feet go fine under my normal beds but not my divan beds - feet are approx.2.5 cm high rising to approx.4cm near the uprights, so check your bed if you want to use this table over it.
The table top is approx. 53cm x 39 cm within the lip (rounded corners) so it takes a standard laptop computer comfortably with space for the mouse, drinks mug etc. It also works well as a side table, and for eating supper off while watching tv - I find that space isn't cramped unlike some tv tables. The top is an attractive rich orangey-brown wood-effect (melamine or similar). The lip height round the edge is negligible (approx.5-6mm) so it won't keep things on the table if tilted much.
Bought this to avoid frequently moving a similar one up and down stairs; my old one wobbles, making me realise how much better-built this one is.
