A possible excuse could be some metal or something was sharp and you cut yourself on it, making it especially worse because you have hepetatis B.

However, due to the size of the item you might just be able to say you don't know how to mail something so big back, and/or disassemble the chair.

If they ask to do a pick up say your super busy and rarely at home or something.

I had the same idea some time ago. Well I tried with both bigger and smaller companies and they just wont proceed. They want picture of everything, wound, chair. Once they said that they werent responsible lol.

Probably DNA is the best right now. I just got one idea in head. You could do contact medium/small company as a youtuber and ask to promote them. Thath could maybe work.
