We have the Jane activa combo high chair.

It has a 5 point harness, the chair is removable so you can take just the chair and the tray with you.

It is a fully reclining chair, and it all turns into a table and chair set when baby gets older, so its not just a high chair its a highchair that turns into a low-chair and then into a play table.

it has a removable padded seat cover which the straps are attached to and you just throw it in the wash and it doesn't take long to dry.

it doesn't have wheels, but the shape and the material its made out of makes it extremely easy to move around. It is very sturdy (not like the ones with very thin metal poles for legs). The tray is removable and we also have the extra part that sits on the tray with a drink holder on it.

I can't praise it enough actually! i definately wouldn't use anything else other than this chair, and its value for money too, because once your baby is too old for the high chair part, you can just use it for a table and chair set, simlpy remove the chair from the base, turn the base the other way and presto you have a table and chair.

we use the recline part of the seat because ds likes to sit back and relax while eating (not straight up, he looks soo uncomfortable like that)

I also have one of those ones that attach to a normal dining chair, a safety first one i think. (its at my mums house for when ds goes there) and imo i honestly feel very uncomfortable when ds sits in it as it only has a 3 point harness and is very slippery cause it doesn't have a cover and he barely fits in it and he is only 15 months old.
