Give your back a break - these are the 9 best thick yoga mats for ultimate support in 2025

Thickness: 6mm | Weight: 1.59kg

Designed with all exercises in mind, but especially yoga workouts, Gaiam's Premium 6mm Thick Yoga Mat isn't just premium in name. It delivers cushion underfoot, support, and a wipe-clean design that's durable over time. I also love the selection of colours and patterns available - especially this mint green.

Since I bought this mat at the beginning of the year, I've used it for a range of yoga, Pilates, strength workouts, and stretching. I find there's just enough cushion to take away the pressure from my joints, without leaving me feeling unbalanced while standing. I love it because it's so grippy on the bottom, so it stays put through the whole workout, and the synthetic polymer doesn't get slippery when you get sweaty.

In the summer, I even took it outside to make the most of the sunshine, and there wasn't a mark on it after a quick wipe. It's also very easy to store away in a cupboard or leave in the corner of the room as it rolls up tightly and stays put, without needing a strap.

The only downside I'd flag is the plastic smell when it comes out of the box. It's intense and takes a few weeks to fade properly, but I can't smell it at all now. Overall, it's a very small price to pay for this budget-friendly buy. Coming in at under £40, it's significantly more budget-friendly than others I've tried recently.

Thickness: 12mm | Weight: 1.3kg

The Stakt mat is my favourite for stretching and my Pilates abs workout, where I'm spending most of the time on my back. It feels firm yet supportive under my back, making it suitable for those looking for serious support, but without that spongy feel in some of the cheaper super-thick mats.

While many of the best thick yoga mats roll up, this one folds away to create a pad that you can also use as a yoga block. It's dual purpose, and if you regularly use a yoga block in your practice, it might even save you money in the long run. I tend to fold it up into a block to stretch out my hip flexors and glutes. The added height really makes a difference.

It's a great option for anyone hunting for the most support possible, but the premium, soft-yet-grippy materials are unmatched in this guide, making it also a good option for anyone looking to be as comfortable as possible as well.

Although it's one of the more expensive mats on my list, I believe that the combination of support, comfort, and versatility makes it well worth the extra spend compared to the Gaiam Premium Thick Yoga Mat, for example, if you have the budget.

Thickness: 10mm or 15mm | Weight: 1.1kg

For just over £10 and with a choice of two supreme thicknesses, it doesn't get much better than the Xn8 Sports Thick Yoga Mat. If you're looking for one of the best yoga mats to buy on Amazon that's also lightweight and ultra-thick, this is the one.

There are two thickness options (10mm or 15mm), and I opted for the thinner option, which I found was enough to support my joints. It feels at least three times thicker than the Gaiam Premium Yoga Mat but spongier than the Stakt Premium Mat. I have no complaints, though. While I wouldn't use it for anything too vigorous, for knee exercises and back exercises, it's a winner.

I admit I went into the testing process for this mat with minimal expectations, given the price tag, but I was very pleasantly surprised. The mat felt durable and reliable during workouts where I was moving around a lot or holding a pose for a longer period. It stuck on the floor without curling up, too, which is a plus.

Another plus - it's sold on Amazon, meaning you'll get quick and reliable delivery with this one. However, given the thickness, it's not a mat I'd recommend for the studio. Despite being relatively lightweight thanks to the rubber material, it's still bulky to carry around. For studio sessions, I'd recommend the Strongtek Extra Thick Yoga Mat.

Thickness: 8mm | Weight: 1kg

At 8mm thickness, the Strongtek Extra Thick Yoga Mat is ideal for keeping in the studio or in your home for a quick session of Pilates for beginners. It has a double-layer structure and is made from TPE, which makes it feel durable and secure feel underfoot.

I have three yoga mats in rotation, and this is one of them. I use this one for everything from Pilates to my weekly weights workout, as it's just the right blend of supportive and stable, being under 10mm. The material feels grippy underfoot but not sticky, and it feels soft without socks. When I took it out of the packaging, I was happy to see the underside had a grippy bottom too, which meant I could use it on wooden or tile floors without an issue.

It's also very lightweight and cleans well, making it suitable for sweatier workouts or sharing with others. However, I did notice that the mat had a distinctive smell on the first opening, and you have to lay it out for a couple of hours to make it flat enough to use. But, otherwise, for less than £40, it's an excellent buy.

Thickness: 6mm | Weight: Less than 1kg

If you're more invested in a good grip and durability (along with comfort, of course) in your mat than anything else, a cork yoga mat might be a better option for you. The top layer feels smooth to the touch, but it's still grippy when in use, and the material deals with sweat quickly, hiding any marks and making it easy to clean your yoga mat. This also means the mat is a versatile option, as suitable for yoga as for heavier, sweatier workouts.

I've had this mat for about seven months now, and I use it for stretching and weighted workouts every few days. When I first opened the box, I was surprised by how thin the cork felt, and I was a little disappointed. But when I got going, I realised that it offered more than enough cushioning for core exercises and my regular weight training workouts. It's also held up really well over time and looks almost as good as the day I got it.

While the Mirafit Cork Yoga Mat does have a TPE foam backing and arrives in a plastic wrap, it's a more sustainable option than the PVC-only options on our list, as cork is a natural material.

Thickness: 6mm | Weight: 3.4kg

Looking for a durable yoga mat that will last a whole lifetime? If you can take the weight, the Manduka Pro Premium 6mm Thick Yoga Mat might be for you. It blends exceptionally high-quality materials with functional use, offering a great balance between cushioning and stability for all kinds of sessions. I tested this yoga mat in a month's worth of yoga classes, Pilates workouts, and home sessions.

While it feels springy and supportive underfoot, the big selling point of this mat is the grip on the underside. I felt secure even on tile flooring, but still felt able to move freely with the thick cushioning under me for support.

If you prefer a darker colour to complement your black gym leggings, this is a great choice as it's only available in muted greens, reds, and blues. It also comes in different sizes to suit yoga lovers of all heights (from 71" to 85").

The only downside - and this goes for most other premium mats too - is that the Manduka Pro Premium 6mm Thick Yoga Mat comes with a little extra weight. At just over 3kg for the regular length, it's one of the heavier mats on the list - almost 2kg more than the Xn8 Sports yoga mat, which is double the thickness. However, this makes it a better choice, in my opinion, for those who prefer to practice at home rather than take their mat to the studio. The premium quality is also unmatched.

Thickness: 5mm | Weight: 800g

If you're a taller yogi, you'll naturally benefit from a longer mat. I'm 6ft tall, and I tested this mat for a couple of weeks to see if it held up across yoga, HIIT, and full-body Pilates workouts.

I've never prioritised longer mats (with options like the Stakt mat, I've never felt I had to), but I have to admit there is a benefit to having a longer length mat. I never found my toes stretching over the edge during a lunge, and I didn't have to keep shuffling down to keep my head on the mat when lying down. It's also very lightweight at 0.75kg, which makes it very easy to carry around.

While I have broken my own rules by allowing a 5mm mat into this list, I didn't find the thickness to be too limiting. It was just right for my weighted workouts and more active yoga sessions, but I would suggest another option for anything where you're on the ground for longer. I also appreciated the bright water-inspired colour, though it looks brighter online than it does in person. It's also not as wide as other yoga mats I've used, but I didn't find it to be a limiting problem.

Thickness: 8mm | Weight: 500g

For me, 8mm is ideal for workouts where you need to move but want more support than 4mm when your feet come to land. At double the thickness, the Adidas Foam Mat is my pick of the bunch for any kettlebell or dumbbell workouts at home.

With the ridged underside, it stays firm on wooden floor and carpet, not shifting even through the higher-intensity workouts I put it through using some of the best workout apps. The foam is medium density, meaning it has a little give underfoot, which I found offered more support during jumping workouts or workouts involving jumping.

As it's made from relatively sweat-resistant EVA/TPE foam materials, it's also very easy to keep clean with just a wipe after use, and the mat isn't so thick that it unfurls when it rolls away, which is great for storing it away after use.

Thickness: 8mm | Weight: 1.5kg

The Yogamatters Everyday Wellness Mat is a long-standing favourite of mine. It blends comfort and support with durability, creating a sturdy surface to exercise on. Having been out of stock for a few months, I'm so pleased to see it's back, as this mat narrowly missed out on the top spot in this list.

I have sensitive knees from a running injury years ago, and I find this mat makes my yoga poses (like child's pose and Shavasana) so much more comfortable. I almost couldn't feel the ground under me. The mat is reversible, but both sides feel grippier than most standard yoga mats to me, making it a great option for sweatier workouts and stability exercises. I also appreciate this when I'm working out in my living room at home, as the mat doesn't slide over the wooden floor.

Compared to other options at a similar thickness, the Yogamatters Everyday Wellness Mat is also relatively lightweight at 1.5kg, and having used it for over a year, I can confidently say it's worth the price. I've used this mat frequently for my beginner's kettlebell workout and Pilates with weights, along with regular stretching, and it's been just perfect.
