I ordered a couple of nice seats form my LTD Commodities book at work. They were only about $10.00, if I remember correctly. They have a weight limit of 18 pounds (and Sasha is pushing that! ).

I don't have any pictures for you, but I can describe them. They have a soft cover, and the board attaches to the window and there are braces that lean against the wall. Both of my girls were not interested in them.... until I put some nip on them and then they realized they are GREAT for laying in the sun!

You can look them up online.... www.ltdcommodities.com. You have to have an account, but you can create one. They say you have to buy in lots of 3, but you don't! You do have to be careful about the shipping and handling as sometimes the rates can be outrageous.... depending on the weight of what you are ordering.

I looked all over before orfering these, and found they were the best price. Good luck!
