I complete this review a year later: I have emerged and re-inflated this year, no problem. The fabric was resilient and there is no leakage (which is not the case of the inflatable pool last year). They always go well with my daughter 3.5 years.
I bought a second pair for my second daughter (18 months). They go to him although they also indicated from 2 years (Yet it has no big arm).
Very good product that resists time.
