I have waited for many months for this to come back In stock, as it’s the only thing size wise that will fit down the side of our toilet, so I was very pleased when I got an email to say it was back in stock :) 
It is rather expensive but it definitely suits our needs so I was happy to pay the price, pretty easy to assemble, and the quality seems decent enough, and not too flimsy, the instructions were simple to follow, thank you :)
