* Comfortable (good padding) * Easy to maintain (that is plastic and in addition it removes and recovers very easily with elastic) * Not bulky (when folded) * Adjustable in height (3 positions available) * Safe (3-point belt + tablet (adjustable on 3 levels)) * Stable (ties behind the back and under the chair) * Easy to carry (use webbing as shoulder) * Worth the cost to pay that price given the quality of the product
