Since we use at home a highchair, we are on the go (vacation, visiting relatives etc.) bought this seat. I must say I find it very convenient. You can attach it to any chair with a backrest in principle, because it has a fastening straps for the backrest and the seat. The seat takes up little space and keeps a lot of. The inflation of the actual seat is very fast and our lively little one can sit fine with us at the table without it can fall out left or right. Of course they do not remains unsupervised. One can the child then lead to separate belt around the waist strap - but beware, it's sort of a 3-point belt only. Trotdem, definite buy recommendation!
