OK, referring to this page, I would recommend the sort of high chair that you strap onto a normal chair, if you have a small house like we do. There's a Fisher Price version at the bottom of the page. We had a First Years one like this, it was absolutely no trouble to clean, and felt safe and secure for a large, strong ds throughout his highchair period. This wasn't that long really (18 months or less?) so was glad not to spend a fortune. Ideal for small house as you still have a normal chair after child has gone to bed, for adult use! I loathe the trip trap for this reason, as it takes up a whole space and I always seem to end up trying to sit on one at friends' houses, v uncomfortable.
I also like the look of (but have never used) the travel versions of these, there are a couple on that page at about £20, I think, which is a lot unless you are always at other people's houses. Handy for grandparents to buy or to get secondhand. I would expect them to start falling apart if used exclusively but don't know.
DS also sometimes used a clipon seat a bit like the Brevi? Dinette ones on that page. Very good early on but later I used to panic at the sight of him dangling off the table, he was so big and sturdy.
