I bought the adjustable table for my invalid wife to fit across her tilting lounge chair. This was the only one I could find that had the right size and looked sturdy enough to do the job. The assembly was very simple, the only tool required was a small spanner that came with the 4 castor wheels to tighten them. I did not even look at the instruction sheet. Before writing this review, I waited several weeks to try to find faults with this table and found none.
