It is lush
- by far the 'classiest' looking HC I have ever seen.
It looks easy to wipe down, no nasty nooks & crannies! (but I would check if that was the case and make sure it's pretty stain resistent - blackcurrants/tomato based sauces can do maximum damage in minimum time!!)
I like the hydraulic height adjustor.
I like the castor wheels.
I like the easy tray release
If it works and I was convinced about lack of a harness ... I like the harness free aspect - just not sure without seeing one if I trust it.
Downsides:
I can see is that it is like a bar stool in that they will need lifting in & out of it, even when quite big - whereas with the Tripp Trapp they can get up and down from a very early age and it's a good flat seat to sit on as a chair where as the BMS looks quite easy to slip off (for fidgeting toddlers).
Appears to only be one setting for the tray? ('trapping' the baby/child in)
I have watched the video several times and I still don't like the 'no harness' bit - not convinced by his spiel. A harness is supplied but it's not too clear how good it would be if you wanted to use the HC without the tray - so they are actually sitting up at the table/breakfast bar.
A TT will last into adult hood this is much smaller (bum size). My Mum can sit on the TT comfortable (she's about 5' 4" 65kg) so a handly spare seat as well. Lots of kids have them in their rooms when it's no longer needed in the dining room as a desk chair.
