Bourton bolster cushions

Someone with a Broadway asked how to stop the bolster cushions falling off the end of the long bench seats. We put brown fabric covered boards at each end wedged between the base and the upright wooden structure at the cab end. They can’t be seen when the bolsters are in place and they don’t fall off the end. We can also sleep either end without pillows falling off. Job done, simple and effective. I will post a photo. I did respond to the question but thought I would post on the Bourton site too. Mrs Jimmee
