To be fair it was miss composite that even suggested getting rid of the sofa in the first place and she who looked up these stands so I’m at this stage I think I need to not push my luck with trying to push something on the wall or the vertical storage. 😀
We’ve been using the lower ones for years. Work well, cope with a 2.3 RQ or equivalent. Ideally you’d clamp them/screw them to the floor somehow as they tend to slide when you push the bike into them. Bikes are a lot less stable if you put front wheel in so don’t assume you’ll be able to top to tail them to save space.
