Amidst all the other injuries sustained over the past two years ... I bruised my coccyx. It made playing very difficult, to say the least. I was researching my options and found someone who would build me the throne I needed. At the last minute, my wife stumbled upon a picture online of a Pearl throne. I checked it out and soon realized it was exactly what I was seeking.
It's the PEARL D-2000BR
It's built for drummers with lower back injuries. It has an interesting tilt to the padding that reduces pressure in specific areas. It also has the most amazing cut-away - right where the coccyx would normally hit. There's nothing there to make contact with it. It has a backrest and a seriously strong four-leg base that stays put.
Pearl's words - " Two Position Seat: One side provides an angled front for free leg movement and a small recessed cavity toward the back to alleviate spinal compression."
I love the throne. It has allowed me to continue playing with no pain in the coccyx region.
