Hi honey
A lot of people use the Poang (sp?) chair and foot stool from Ikea. I personally use a beauty bed and have a nice warm heated blanket underneath the towelling fitted sheet. I start with my clients sitting on my comfy manicure chairs and have their feet in the pedi bowl and we go through the consultation form and they have a quick coffee or tea. Then I dry their feet, get them to hop in the bed and anyway we go. If I am using scrubs and masques I have a nice hot bowl of water with either flannels or towelling mitts to wash them off.
Drove me mad trying to find a way of doing pedicures but I love doing it on the bed. Bless one of my clients the other month, she nodded off! For mobile I have a foot stool on its own no stool for me to sit on) and that works really well as I don't fancy humping my couch around and besides I can never put the bloody thing up without some kind of ninja move anyway!
Not sure if that's any help to you, but worth a consideration if you can't find what you want. There is also a really good pedi set up thread on here that may be worth having a read of- that's where I got the idea.
