This may be totally unhelpful since you said you wanted to order online -- BUT, if you're anywhere near an IKEA, I can't say enough good things about my Antilop high chair. The tray is a nice size, and I love that the chair is table-height so you can pull it right up to the table as an alternate option. The chair is solid plastic -- easy for wiping clean -- and a comfy bucket shape. And the whole thing's only $25 bucks! Even if it doesn't work for you, OP, just in case anyone out there is looking for a good (cheap) high chair, we love ours.
