Yael, we don't have wooden (I am totally in love with the Ikea Antilop.......)

BUT, in all of the restaurants I worked in before I moved to Aust........they were all wooden, and saw some major heavy duty and were brilliant.....there is one fantastic style that you can get that is really similar to the Ikea one...and cleans up SO easily and quickly....

From memory the brand name is Lipper.

It only has a groin/waist strap, but that was no problem, (Same as the antilop.....none of my 3 have ever managed an escape.)

It doesn't come with a tray, but rather you push it up to the table. Which can be a bit messy, but the huge advantage is that you can keep them in the chair for a lot longer as they feel like they are really part of the action by being at the table! (Lexie is still in her high chair no problem........)

I will pm you a link to a photo of it.......
