I have now the 2 seat cushions, the 1st had been at delivery a faulty battery (not loaded). That, however, was replaced immediately - and the second is doing what it should. I've bought my grandma that they like to walk, but also repeatedly requires a seat break - but this on cold benches is not possible in the spring and autumn. Thanks to this part they can now walk in the colder transitional period and take breaks. Really great !
