The simple answer is: Yes!
The Anthros chair qualifies as specialized/ergonomic chair that could be used to help treat or mitigate a medical condition. Most customers that have used their HSA/FSA funds have gone through the following process:
Call your administrator for their specific requirements.
Get a Letter of Medical Necessity (LMN) that explains why the chair is needed. We have a physician who offers free LMN's to Anthros customers: https://www.anthros.com/hsa-fsa#book-a-call
Purchase the Athros chair with a personal credit card and submit to the administrator with the LMN for reimbursement.
If the reimbursement is denied, Anthros will provide a full refund, no questions asked.

Pro Tips:
Reach out to your HSA/FSA administrator to find out what they will need to approve the purchase.
You can try using your HSA/FSA card, but Anthros is not a medical device and will not be recognized by most providers.
