Hi Roxanne, they're made by Staxi. Here's the url to the product (it may not be a clickable link) - https://staxi.com/chair/staxi-medical-chair/
The blue ones by the entrance? I'm unsure what brand they are, but if you look at the branding, you should be able to find them online through a medical materials supplier. As a back up, you should be able to ask the purchasing department of the hospital who is in charge of ordering stuff like that, they might direct you where to get them from a bit better.
