Is the Salon in your home or an actual shop? Just trying to get a mental picture!
I got a gorgeous glass shelf unit with a door from Ikea. I think it was about £80. It has a glass door as well and it is perfect. I also have a kind of squiggly shelf unit. It's in kind of an 'S' shape. It is pine and crome, and it works well because not all my products are in a straight line, so it is eye catching. They still sell both of these.
What Colours are you going for?
I got some office chairs luckily from a supplier at my Mum's work. They are amazingly comfortable. The clients chair is designed to fit in the arch of your back, and has arm rests. And mine has moveable seat and back rest so you can find the perfect position for yourself, and also the arm rests move to whatever height you need.
If you find chairs you like but they are the wrong colour then choose a material and you can get somebody to back them for you. It'll save on trying to find the right chair in the right colour, believe me!
As for clients waiting, get one or two tubs chairs from Ikea or check on the internet, as these can sometimes get too expensive.
Hope some of this helps.
