First Years Inflatable booster seat

Mumsnetters' comments: This innovative design has an inflatable seat, offering "greater height and comfort". Although it doesn't fold away particularly small it's "very lightweight" and the straps mean "it can easily hang on to the back of a pushchair" so it's "ideal for restaurants and holidays". Plus: "I have yet to come across a chair it doesn't attach to and because it's fabric it doesn't mark the chair". One user remarked: "we never get round to deflating the base, but it doesn't seem to matter, it still packs away very well". Overall: "a great value second highchair".

I borrowed one to try out with my daughter at around age 1. It was easy to fit to any chair, but if she leant sideways it seemed very unstable. It was reasonably convenient to take away but I didn't feel that convinced about the safety of it when she moved about.

Found this really useful for our son, but they have to be quite steady as the straps are low down at the waist and they can fall sideways, so not suitable for very small children. On the whole though useful, very light and easy to store. They also need to be tall enough, as even when fully inflated my 1yr old daughter is just about reaching the table, but still have to watch for head bashing.

great and hand to pack and take on our weekends away to family etc. I also use once I got rid of the big bulky high chair.

Doesn't give a very large boost, but useful for its straps and portability
