Big fella

Hi Wasim no i haven't had any success yet but i can still certainly say that the welcab chair we have is totally brilliant but the wheels are a bit soft and if you have anyone bigger than a small adult or child it makes the chair quite hard to push but apart from that its a fantastic system,not sure if you could change the seat but i can recomend buying the factory fitted job,i have heard of replacement hard wheels but just don't know how to source them or indeed where from.

I'm trying to buy replacement wheels or solid tyres for my 2010 Alphard welcab seat can anyone tell me where or how to do this thanks.
