That's awful Karl! My shower chair is one of the ones with suction feet so it doesn't move. I've had mine a while now and is still going strong. But I've noticed my holiday wheelchair is rusting quicker. I'm on mark 2 now and I only had mark 1 for just over 2 years that's 4 holidays! I do think these mobility companies are skipping on quality control so they can pump out more products for a bigger profit as the population explodes. As an example look at the problems I had with my stair lift, the chap that fitted it and came out and fixed it twice said the problems where due to a 'bad batch'. Turning a blind eye to quality control!!!
thats exactly what i have...have my original from 15 yrs ago... have bought 2 new cushioned seats since then but everything else is the same... just get your attendant to help wash it clean every 6 months to a year and squirt a little wd40 in the wheel/caster joints and it'll be fine for a long time, anyway if you are still looking for a new one - i would suggest you to check the list with the top of non expensive and most comfortable shower chairs
