I purchased the pod clip-on highchair in order to avoid the standard bulky floor based highchairs. I wanted something that was easy to 'install' and then pack away into the cupboard when not in use. The pod delivers just that. It is strong and well-made, and feels very safe and secure when installed. I was concerned it wouldn't fit on our table as it has a frame underneath the table top - but the frame was far enough back from the edge that the pod fit without hassle.
I would highly recommend this - especially to grandparents who need something on hand, but don't want the bulk of a floor-based highchair every day. It is also compact enough to be perfect for travelling with.
We started using this when our granddaughter was 5 months old. She loves being at the table with everyone else.
