Hi Cajunj:

I got one of these for my 84 year old mom. She was complaining about her back hurting when she cooked. She loves it! I got her the truffle color and it matches pretty well with her wood floors. Sorry no pics.

I imagine it would also be good for knees.

FYI:

I saw at Bed, Bath and Beyond they have it (as advertised in their flyer) and if you use the 20% off coupon, it's for $80 which is better than the $100 I spent! In fact, I'm going to get another one for her for Christmas--she wants one at her cooktop area and one at her sink area.
