How to fix it
Work through these in order, the most common causes come first.
Why Curling Happens
Yoga mats are shipped tightly rolled, often compressed for weeks or months in transit and warehouse storage before reaching a buyer.
Most materials, foam, PVC, rubber, hold some memory of that rolled shape temporarily once unrolled.
This is a completely normal, expected characteristic and not a sign of a defective product.
It typically resolves with in a few days to two weeks of the mat being used and left unrolled between sessions.
Cold storage tends to make it worse, since materials are generally less flexible and slower to relax at lower temperatures.
Speeding Up the Process
Flat, heavy objects placed along the curling corners and edges for a day or two is the most reliable way to encourage the material to flatten faster than waiting alone.
Rolling the mat in the opposite direction of its factory curl for short stretches can help counteract the shape memory, then unroll it flat again.
A warm room or brief indirect sunlight can help, but avoid prolonged direct sun or high heat, which risks damaging the material rather than helping it relax.
Diagnosing Your Specific Problem
Mat is brand new and curling at the edges: normal shipping-related curling.
Give it time and consider weighting the edges to speed things up.
Mat has been used for a while but recently started curling more: likely related to how it's been stored, check whether it's been kept tightly rolled or in a cold space between uses.
Curling is severe and doesn't improve with flattening techniques after a couple weeks: could indicate the material is starting to degrade, more common after a few years of regular use, which may be worth considering as a sign to evaluate replacement.

FAQ
Common questions
Why does a brand-new yoga mat curl at the edges?
Nearly all yoga mats are shipped tightly rolled, sometimes for weeks or months in transit and storage before reaching a buyer, and the material holds that rolled shape temporarily once unrolled. This is normal and almost always resolves with in a few days to two weeks as the mat relaxes into a flat shape through regular use and, ideally, some added weight or flattening technique.
How do I flatten a curling yoga mat faster?
Lay the mat flat, unrolled, in a warm room and place flat, heavy objects like books along the edges and corners for a day or two. Some practitioners also gently roll the mat in the opposite direction of its factory curl for short periods, or leave it in gentle sun for a short time, which can help the material relax faster, though very high heat should be avoided as it can damage the surface.
Does how I store my yoga mat affect curling?
Storing a mat tightly rolled for long periods, especially in a cold space, encourages it to hold that curled shape even after use. Storing it loosely rolled, hung, or laid flat when possible helps it mainta in a flatter resting shape over time and reduces recurring curling.
Is a curling yoga mat a sign it's damaged or needs to be replaced?
Not usually, especially if it's new or was recently in storage. Mild edge curling is a temporary material characteristic, not damage. If a mat that has laid flat for a long time suddenly starts curling, or if the curling is severe and doesn't improve with flattening, it could indicate material degradation, more common after several years of use, which may be a sign it's nearing the end of its useful life.
