Upon buying my Kaiser 2, I found that my spirit king also needed this, and what a difference over the standard neck pillow. This type of cushion should be on all your chairs, charge for it, the comfort is worth the money.
Good add on for my Spirit King chair. Better than neck pillow who came with my chair.
Does not work with the T-pro II
I tried to inquire if it would fit with the T-pro on a few occasions, and didn’t get a response, so I went ahead and bought it to try.
The headrest sits too high on the T-pro, and the elastic is too short to put it lower.
Large Size Memory Foam Pillow
Highly recommended, excellent customer service and awesome comfort
