Easy to assemble. Needed a thin 2 foot pole to push the electrical cord through poles but once I found that to help it was done in minutes. I have a sun lamp that was over 200 and is very large and awkward so it’s hard to use without difficulty. This sits beside my chair and I can now read  night and have begun sitting under light for 30-60min a day to help with depression and vitD. Definitely a need for me in winter and a quarter the price of other. Very satisfied. It was a great deal.
