@variablepulserate Far from it:
- I wear 28.5"x30" trousers, which are pretty hard to get. Best fit for me is Uniqlo's chinos, smallest size (29"), and get them shortened.
- 3E-width feet means only a few brands of shoes fit (I wear Vivobarefoot shoes and have bought enough to know my size and how they'll fit, usually)
- Mattresses, I think, should be tried IRL before buying. I'm not sure about types — I just look for a really stiff one usually.
