PERFECT FOR MOST YOGA STYLES
Thanks to its thickness of 15 mm, it is particularly gentle for the joints. It offers excellent cushioning for all levels of yogis.
Why Standard Yoga Mats Hurt Your Knees
Most yoga mats are designed for professional studios with sprung wooden floors. They’re thin, firm, and work perfectly in that environment.
But at home? On cold laminate? On hard tiles? On unforgiving concrete?
That 4-6mm of foam does almost nothing.
Your kneecaps press into the floor. Your tailbone grinds during sit-ups. Your elbows ache during planks. And cold UK floors make winter Savasana genuinely uncomfortable.
This extra thick exercise mat solves every single one of these problems.
At 15mm thick, you get 1.5 centimetres of high-density foam between you and the floor. When you kneel, the foam gently compresses around your knee, spreading pressure across a wider area.
No more sharp pain. No more rushing through kneeling poses to escape discomfort.
What Makes This Padded Exercise Mat Different?
Maximum 15mm Cushioning
To put the thickness in perspective:
- Standard yoga mats: 4-6mm
- Our 10mm mat: Good cushioning
- This 15mm mat: Maximum cushioning
This is our thickest mat, designed specifically for anyone who needs serious joint protection.
High-Quality NBR Foam
We use NBR (nitrile butadiene rubber) foam – the same material trusted in physiotherapy clinics and rehabilitation centres.
Why it matters:
- Soft but supportive – Cushions without bottoming out
- Warm surface – Doesn’t feel cold like PVC or rubber
- Moisture resistant – Sweat wipes away easily
- Long-lasting – Maintains shape through years of use
- Skin-friendly – Hypoallergenic and phthalate-free
Non-Slip on Both Sides
The ribbed texture grips your hands and feet on top, whilst the textured base locks onto wood, tiles, laminate, and carpet underneath.
This exercise mat for hard floors stays exactly where you put it.
Who Should Choose This Yoga Mat for Bad Knees?
People with Sensitive or Painful Knees
Arthritis, old injuries, or knees that simply complain – this yoga mat for bad knees makes kneeling comfortable again. Cat-Cow, Low Lunge, Camel Pose… finally enjoyable instead of something to endure.
Regular Pilates Practitioners
Pilates involves rolling on your spine, lying on your side, and pressing bony areas into the floor. This Pilates mat 15mm protects your vertebrae during roll-ups, shields your hips during side-lying exercises, and cushions your tailbone during The Hundred.
Anyone Exercising on Hard Floors
Laminate, tiles, vinyl, concrete – UK homes are full of unforgiving surfaces. This padded workout mat provides both cushioning and thermal insulation, keeping you comfortable and warm.
Those Wanting Extra Joint Protection
Whether you’re over 50, recovering from injury, or simply prefer more comfort, this mat delivers. No more folding towels under your knees for extra padding.
Pregnancy and Postnatal Exercise
The extra thickness supports side-lying positions and provides a stable, cushioned base for gentle prenatal stretching.
Extended Meditation Sessions
Long sits demand serious comfort. This thick meditation mat supports your body without creating pressure points, even during 30+ minute sessions.
An Honest Note About Balance Poses
We believe in being upfront.
Because this mat prioritises maximum cushioning, it feels slightly softer underfoot than our 10mm version. For most yoga and Pilates, this is exactly what you want.
However, for single-leg balancing poses like Tree Pose or Warrior III, you might feel less stable on the soft surface.
Our recommendation: Simply step onto the firm floor for balance work, then return to your mat for floor exercises. Many customers do exactly this – and they wouldn’t swap their 15mm comfort for anything.
15mm vs 10mm – Which Thickness Do You Need?
| Your Priority | Choose 15mm | Choose 10mm |
|---|---|---|
| Knee or joint pain | ✓ Best choice | Sometimes suitable |
| Pilates and floor work | ✓ Best choice | Good option |
| Very hard floors (tiles, concrete) | ✓ Best choice | Sometimes suitable |
| Maximum comfort priority | ✓ Best choice | Balanced comfort |
| Standing yoga and balance poses | Sometimes suitable | ✓ Best choice |
| HIIT and jumping exercises | Not ideal | ✓ Best choice |
Still deciding?
Choose this extra thick yoga mat if comfort and joint protection are your priorities.
Choose our 10mm mat if you need an all-rounder with more stability for standing poses and HIIT.
Bonus Use: Camping and Travel
Here’s something our customers discovered:
This mat makes a brilliant camping mattress.
The 15mm foam provides excellent insulation from cold ground and smooths out uneven terrain under your sleeping bag. It rolls up compactly with the included strap and weighs far less than traditional camping mats.
Not just for yoga – genuinely useful.

Ami –
Let’s get the more obvious elements dealt with quickly. This arrived swiftly, well packaged and undamaged.It comes with a nice storage bag and a clever little strap gizmo. What does it do? It slides over the mat once you’ve rolled it, and easily and simply holds it rolled up. I’m the clumsy guy who could never fit a sleeping bag in its case, and even I can (first time and every time) neatly roll this and fit it in its bag.The mat is soft yet supportive and really pleasantly warm to the touch. I went for the purple colour and it has a WHAM! factor on the eye that I find mildly helpful for revving myself up to exercise.So, I think it’s worth stating at this point that I’m a beginner at exercising. I’m clumsy, somewhat overweight (weighed >80kg when I started using this). I’m not sure if this makes me a good reviewer or a bad one – maybe it depends on what state you, the reader are in. Despite my awkward movements, I’ve found the mat doesn’t slip and slide on the hard floor underneath it, when my feet (whether in socks, trainers or bare) sometimes do. Perhaps if I was a hardcore exerciser I might be moving so aggressively that might change, but I reckon it’s good.But my novice status also led me to do something that, it turns out, was unwise. I used a step (as in for ‘step aerobics’) on top of the mat. It gave a nice, comfy, slightly bouncy quality to my steps. But… it also left what seems to be permanent dents in my brand new mat. I can’t quite decide, in my innocence, if this is a fault in the mat or just sheer stupidity on my behalf. It’s even possible there were instructions in the box when it arrived telling me not to do this (my kid opened the packaging, rather enthusiastically, so I didn’t see any instructions).So, you can understand why I hummed and hawed about whether to take off a star, just for this. In the end I did, because I think it’s reasonable to think you could use a step in this manner without damaging the mat. I’m an enthusiastic reviewer, but on this occasion, I think I need to be slightly harsh.For me the big question always is – “Would I buy this again”? And if you’re wondering that, the answer is… absolutely. It’s lovely to exercise on, even if the exercise itself if anything but lovely.But… I wouldn’t put a step on it again.

Aud61 –
Unfortunately it does not come with the carrier pictured – it comes with a cheap plastic & net bag impossible to roll mat back into it – am going to have to buy an elastic strap as it’s hard to roll up & carry
Hils –
Bought for pilates. Good value and very thick foam
Gilly Payton –
Thick enough to cushion without affecting balance. Would buy again.
Ahmed MOA Eldemerdash –
Good quality , arrived on time ,
occasional customer –
Thicker than standard and is therefore kind to knees. Longer than average too. I would have liked 2 carrying straps to go over each shoulders rather than one but just a minor complaint.
Kimberly L. –
Very happy with this mat, especially the thickness of it. I find it very comfortable for all my exercises. Would definitely recommend!
Julie B. –
A thick mat and very good quality
Anna B –
I’ve owned several exercise mats. This is definitely the thickest and most comfortable. Worth spending the extra few quid for. I highly recommend.
FIONA –
I use this for pilates and yoga. It’s excellent. The thickness means knees are cushioned. Two convenient carry options too.
linda marsh –
I used this for Pilates. It’s extra thick and does not curl up at the ends. Comes with a carry case, was very pleased with this may.
Amazon Customer –

Seller Sissy –
Fabulous and would recommend this for yoga, Pilates, or any exercises or meditation comfort
Anne Murphy –
Delighted, lovely and soft. Using it for pilates. Fast delivery.
J Gardner –
Bought for my mother who has had 2 hip operations and finds exercising on any mat a struggle as too thin and painful. She has found this very comfortable, and she can lie on each side with no pain at all. Would recommend on that basis.
Kindle Customer –
This product is the best I’ve had by far extremely comfortable and good size I’m 6ft plus and I fit on the matt perfectly. I’ve even fell asleep on it but that’s our secret
Amazons Customer –
People may think you can only use this mat for yoga, but it is great for many other uses also! Even it feels comfortable to kneel on when getting down to clean baseboards. Also great for giving comfortable foundation for working at low levels like under the sink or a lower cabinet.I love thickness of this mat, feels like a memory foam cushion between me and the floor! I always wanted to thick mat because to keep my knees protected from the floor as I do lot of other actives as well as yoga. This mat is exactly what i needed. Planning to buy another to gift my friend!
Webbester –
Good product, very thick as described and comfortable. However, it’s pretty easy to leave marks on the mat due to the force exercised on it during ab workouts.
PKN –
They do the job. Adding pictures for reference. It may be a small thing but the lines on the mat are horizontal and so as your feet rub on it, sometimes it gets squeaky. I wondered why the other mat didn’t do that and I saw vertical lines on it instead. Probably that made a difference. Very comfortable and light.
Mrs E.A.Turner –
Lovely and thick. Exactly what I needed
Ruta –
I was surprised with the quality – superb! Certainly the best I ever used.
Emma Reed –
Super comfy mat for Pilates and studio / home use. I suffer a bony and slightly weak lower back and this has proven great!
Amazon Customer –
Super

Sargy O Leary –
The extra thickness of this mat is worth the money…It is made from quality material and is very easy to clean
Amazon Customer –
Perfect
A. Rodriguez-Felipe –
Fantastic and comfortable Mat…
Claire Behan –
Best mat for thickness
Bloomsbury Babe –
As specified, this is a thick mat which makes for comfort. It is quite bulky when rolled up but has a very tidy carrying bag and is very light, therefore easily portable. It’s just what I needed for some floor exercises following a hip operation.
CM –
It’s lovely and soft exactly what I’ve expected. As the current virus dictates, due to the need of social distancing my local gym had moved to a performance venue with hard floor surface. This mat is simply ideal for the hardness of the wooden floor.However the elastic band provided to tidy up is too small and due to the super thickness indentations made do remain on the mat. But on the whole I recommend the product
LL –
I use this make of mat at home to do pilates. I have used it for over two years and it still looks like new. I have bought a second for when I go back to my live classes in the studio. I highly recommend this product.
