I exclusively use the large armrest. A month ago I updated the furniture in my studio. I ordered these pillows for myself and the tattoo artists of my studio https://www.ggworkshop.net/products/tattoo-arm-rest-xxl-pillow-size-70x37cm. I've been absolutely delighted with these armrests for a month now. Working has become much more comfortable. Clients also notice that after a long session there is absolutely no fatigue. The armrest will last forever as the structure is made of steel. The pillow itself is very soft. The armrest is adjustable in height and tilt. I recommend going to the website and reading the description.
