So, working from home on my dining room (and only) table, I have a few monitors and in order to get them to the right height I shove a couple of shoeboxes and books under them to get them to the right height. I don't have access to shed/back garden and general tools so building my own is not an (easy) option. Ideally I would like a simple box shelf or a low coffee table I can just place on my current table. A box structure of 2ft x 1 ft x 1ft. I had a look at charity shops and skips and as usual when I need one they are not around. I was thinking maybe a wall shelf which might have a back on it so it is pretty study/sturdy but can't see anything. I have tried argos/IKEA and online but no luck as yet. Any ideas from similar people with such problems ?
