Thank you for your question! The chain for this chair is 6.5' long. The ceiling mount itself is specific to the material it is to be attached to thus is not included with the chair. To inquire of the type of hook/mounting hardware you will need to hang your bubble chair, visit your local hardware store. We hope this helps. Cheers!

how thick is the acrylic glass?

For those who live in industrial lofts.... will we be able to switch out the 6.5 foot chain for a longer one? or add to the end of the provide chain?

Hello, it is a 1/2″ thick clear acrylic bubble shell. You can certainly switch to your preferred chain or add the provided one :)

can you take out the coushen if you want to

Yes!
