Bought it two years ago and have been using it regularly since, but I still can't see any sign of wear or damage yet! Very pleased with the quality and comfort too. Have already recommended it to a friend and will probably get another pair when they're in stock again.
The first toy we received was broken, but amazon was great at arranging a replacement and pick-up from home so the exchange was not an issue. And the new toy became a favourite of the 1 year old birthday boy, so overall was a success!!
I have been using it everyday continuously for two years but the seat is still as new (didn't sink in) and still looks immaculate (after relatively rough use)! I have also had to dissemble the seat to move houses... but due to it's high quality metallic fastenings, there is no sign of damage (my first chair from a different company fell apart on re-assembly and had to be thrown away). I would definitely recommend this to a friend.
