Notes
Notes from building and maintaining this catalogue: what the data turned out to be, where listings lie, and what changed in the mats themselves. Nothing here is a rewritten press release.
- Open cell or closed cell is the spec that decides how your mat behaves when you sweat
Aug 8, 2026 · Thickness gets all the attention. Surface type is what changes on the day you practise in a hot room. - A price with no date on it is not information
Aug 8, 2026 · Every comparison page we studied while building this site showed prices. Almost none said when they were true. - The long version of your mat costs about ten dollars more and nobody mentions it
Aug 8, 2026 · If your hands leave the mat in downward dog, the problem is the mat, and the fix is a size most people never see. - Half the mat listings we mapped had no price at all
Aug 8, 2026 · Amazon variation parents look like products and behave like folders. Here is why they broke our first price run. - A $21 Gaiam and a $144 Manduka: what the extra $123 actually buys
Aug 8, 2026 · Both are yoga mats about 6 mm thick. The gap between them is real, and it is not what the marketing says it is. - Why this site shows no Amazon price for the Lululemon mat
Aug 8, 2026 · Lululemon does not sell through Amazon. Rather than invent a number, our pages say so. - Manduka has quietly retired the GRP. Everyone is still comparing against it.
Aug 8, 2026 · Search suggestions are full of "Manduka PRO vs GRP". Manduka itself no longer sells a mat called GRP. - We checked 13 yoga mat listings in one day. Three pointed at the wrong product.
Aug 8, 2026 · Amazon listings get remapped to different products, and nobody tells you. Here is what that looked like on our first run.
