Extremely high CPM for facebook ads

I am testing a product on facebook ads with new business manager, The product is orthopedic seat cushion(product cost $40). I am getting the CPM of $40-60 which is extremely high, All of my fellow advertisers are getting the CPM of $15-20.

The interests I was testing – Health, Chair, Cushion, Mattress, Health & wellness, Pillow

My ad creatives are also decent.

Any expert or experienced facebook advertiser have faced this problem, if yes, How can I get around this? With this high CPM, I won't be able to make any profit.

Thank you.
