Two points I’d like to make that are related to chairs in general:
1. Just seeing the chair itself, let alone sitting in it, makes my heart plummet into my stomach. My childhood dentist’s chairs were much more reminisce of that “old haunted asylum” style, where everything was purely functional and never comfort or aesthetic. The newer kind are much nicer. They look a BIT more like regular leather furniture, or like a car’s interior, and it makes a small difference. They just don’t look as scary as the old kind.
2. Personally, I don’t like being laid back, but I tolerate it. I don’t think I’d like sitting up, either. I just don’t like the way they practically tip you backwards. The backward angle is very slight but it feels like I’m going to slide right down the head side of the chair, and sometimes it triggers my vertigo.
I wish I had something better to do with my hands. the arms of dentist chairs are so small nowadays. I need something so my hands can “white knuckle it” through the appointment. Everything above my shoulders is occupied but my limbs end up feeling too unsecure. Like an imbalance of weight or sensation, I guess. It makes me feel like I’m either losing connection with my body or super hyperaware of its “lightness”. Wearing the x-ray vest does help with this.
