The Cosatto 3sixti looks great. The seat is large with two recline positions, a padded cover, and an easily removable two-part tray (the top part can go in the dishwasher). The seat cover is easily removable, which is of course important since you need to clean underneath it. The chair’s easy to clean too, because it’s all moulded and rounded, so there aren’t so many nooks and crannies for all the junk to get wedged into.
The straps are easily adjusted, but I found they didn’t stay in position. No matter how many times I shortened them, they’d slipped back down again by the next time we used it. There’s also a plastic, um, thing that sticks up between the baby’s legs and I found this incredibly useful: it meant there was no fear of Joe sliding out from under the tray, even as I was strapping him in.
The seat can be raised and lowered via a gas lift like on an office chair, but we didn’t really use this since it was the right level for us anyway. The chair also spins 360 (hence 3sixti) degrees, which was useful too, although I didn’t feel like it was quite as stable when it wasn’t facing forward. If Joe started rocking back and forwards (usually with excitement at the sight of oncoming food), I worried he was going to break it. It also has castors so you can move it around easily but it doesn’t move when the baby is in it (at least it doesn’t on a carpet).
The main negative for me is that the ‘footprint’ of the highchair is too big. We’ve only got a small house and the 3sixti takes up quite a lot of space next to the table. My other complaint is that, being made of plastic and with a PVC cover, sadly, it certainly looks cheaper than the £150 price tag.
