If your yoga mat won't lie flat and the edges keep curling up, the cause is usually storage or a new mat that hasn't relaxed yet. We cover 5 common reasons a yoga mat curls and how to fix each one.

Step-by-Step Guide

  1. 1

    Fix 1: Give a new mat time to relax

    Unroll a new mat and let it sit flat for a few days before assuming something is wrong. Most curling from shipping and storage resolves on its own within a few days to two weeks of regular unrolled use.

  2. 2

    Fix 2: Weight down the edges

    Place flat, heavy objects, books, weight plates, along the curling edges and corners for a day or two. This encourages the material to relax into a flatter shape faster than simply waiting.

  3. 3

    Fix 3: Try reverse rolling

    Gently roll the mat in the opposite direction of its factory curl for short periods, then unroll and lay it flat again. This can help counteract the shape memory built in during shipping.

  4. 4

    Fix 4: Use gentle warmth, carefully

    A short period in a warm room, or brief, indirect sunlight, can help the material relax faster. Avoid prolonged direct sun or high heat, which can damage or degrade some mat materials over time rather than help them.

  5. 5

    Fix 5: Change how you store it long-term

    Storing a mat loosely rolled, hung over a bar, or laid flat rather than tightly rolled for extended periods reduces the chance of recurring curling. Cold storage spaces, like an unheated garage, can also make materials more prone to holding a curled shape.

A yoga mat that won't lie flat is annoying before every single session, catching a foot mid-pose or curling back up right as you're trying to relax into savasana.

Almost every case traces back to one simple cause, the mat spent time tightly rolled, either fresh from shipping or during storage, and the material is still holding that shape.

The fixes below range from simply waiting it out to speeding the process along, and cover the less common case of a mat that's curling because it's genuinely wearing out.

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 within 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

Weight the edges down. 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.

Reverse roll it briefly. 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.

Use gentle warmth. 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.
