First retirement fail!

Being old and decrepit, I struggled to get off our sofa/chairs so bought myself a swivel chair. It arrived yesterday - perfect timing for my ‘retirement’. Started assembling it last night. Was doing marvellously but struggled with the armrests. This morning I looked at the diagram (after I had wrangled the armrests into place and screwed) to see that I had put them the wrong way around. I gave a little whoop and realised that that was why we were struggling to get them to fit. So I boldly unscrewed and turned them round. Yep, easier to see the holes, surely easier to screw in place!Nope!!! 4 screws still missing, neither sis or I can get the buggers to go in! Lots of swearing later and we’ve caved and asked my brother to come and have a go. This as I type from the top low sofa!!!
