Like others, I did wonder if I should spend £200 on a chair or buy an eyepiece. I have to say, I’m glad I bought the chair. It is a very simple design and very well made with quality materials. Sometimes things just feel right and this chair does. It is comfortable, easy to adjust and just about the right size. I don’t really have any negatives, just the fact that it’s expensive but then there’s a certain satisfaction in owning something that gives you pleasure even when you are not using it.
