If by cocsill(?) you mean your tailbone, you might try modifying the seat yourself. I believe you need to lower the front of the seat to shift weight off of your tailbone and distribute it more forward and more evenly. You might also dish the whole seating area. The idea is to have your weight evenly and fully supported. It's not tough to do. Pull the staples so you can peel the cover back, not off if possible, to expose the area you need to modify. Here's an excellent website that explains the whole process. I've done several.
