A lot of people ask about what easels I recommend. In our classroom studio we use two:
H-frame Winsor Newton Shannon Easel
It’s sturdy and well-made for the price. A hidden knob and pin make it non-intuitive for new students, but eventually they figure it out.
Lightweight, affordable and very easy to use. We use pony clamps to secure the drawing board for more stability.
The tabourets are actually laptop stands I bought from Overstock.com. They are a perfect height for holding pencils and palette next to you while you work.
This is my personal studio easel, I love it:
Craftech Sienna Counterweight Easel
