Not what you have asked about but a friend of mine (now sadly deceased) had a Monarch Smarti which folds up incredibly small and you can pop in the boot of the car relatively easily. We used it on our trips all over the world. It revolutionised our travelling. And it would take his 21 stone.
Everything come back to what you’ve been told by the Citizens Advice, under the Consumer Rights Act 2015, goods must be of satisfactory quality and fit for purpose and as described and it’s obvious that this is not fit for purpose because it was purchased to do a particular job and it will not do that job.
You can’t beat the retailer with a blunt instrument until such time as they pay up and your only remedy is to take them to the Small Claims Court.
You need to put that in writing giving them until, say, 4 PM on Friday, 30 June failing which you will issue court proceedings without further notice. I wouldn’t be hanging around.
The new Moneyclaim beta system is easy to use: https://www.gov.uk/make-money-claim
the new system is much better than the old government Gateway system.
You can prepare the proceedings now, at your leisure, save them, and then just pay the fee and press the button when the deadline in your letter before action, expires.
It's then just a case of following the court process and responding to any emails that you receive.
Please note that this is on the strict understanding that you told them when you are buying it but you wanted one that you take with you on coaching holidays. AND it’s on the strict understanding that the company you want to don’t have a particularly low weight limit. If you tried to other companies who have the same weight limit, then it would appear that it is indeed not fit for purpose.
If there is a different model which will do what you want, that would reinforce your claim but even if what you are looking for is an impossibility, you still have a claim.
