01 / PRODUCT
Choosing the right mat
Thickness, size and surface type should follow from the kind of training and the conditions in the room.
What mat thickness for MMA, BJJ and judo?
For disciplines with throws and ground work, the standard is 4 cm. For technical training, stand-up work and sessions without frequent high throws, 3 cm is worth considering. The choice should reflect how your training sessions actually run.
What thickness for boxing, kickboxing and Muay Thai?
For professional striking gyms, consider 3 cm mats, which in the GYM4 range are firmer than the 4 cm version. For lighter exercise zones, 2 cm is an option. If training includes frequent takedowns, the choice needs to be reassessed.
Which mat for athletic conditioning or fitness?
For bodyweight exercises, mobility work and light activities, 2 cm mats are worth considering. Foam mats should not be used under heavy equipment, racks or machines, or in areas where weights are dropped.
Which mat for children, a school or a nursery?
Thickness depends on the type of activity, not on the users' age alone. For classes involving throws and falls, choose a surface suited to those loads; for lighter movement classes, 2–3 cm is an option.
100x100 or 60x60cm mats?
A 100x100 cm module covers 1 m² and is convenient when equipping larger rooms. The 60x60 cm format gives more flexibility in small rooms and with irregular floor layouts.
What are GYM4 mats made of?
The mats are made of EVA foam with properties selected for sports use. When choosing a specific version, take into account thickness, firmness, type of training and the subfloor.
02 / TRAINING
Choosing a mat for your discipline
Do not go by the name of the discipline alone. What matters most is the type of loads and falls and the way classes are run.
Is a 3 cm EVA mat suitable for MMA?
It can work well for technical, stand-up and ground training without frequent high throws. For intensive takedowns and wrestling sessions, we recommend considering 4 cm.
Is a 3 cm mat enough for judo?
For judo training with regular high throws, we recommend 4 cm mats. The 3 cm version can be considered for selected technical drills without intensive falls.
Which mat should I choose for karate?
For lighter technical training and classes without intensive throws, 2 cm is an option. For more dynamic training, it is worth assessing the 3 cm version and the nature of the exercises.
Which mat should I choose for wrestling?
For training that involves regular throws, takedowns and intensive ground fighting, we recommend 4 cm mats. For demanding applications, the subfloor and the build-up of the whole surface should also be assessed.
Which mat should I choose for a boxing gym?
For technical training, footwork and general conditioning, 3 cm is worth considering. Foam mats are not intended for use under heavy bags, racks or equipment that stays in one place permanently.
03 / INSTALLATION
How many mats do you need and how do you lay them?
Have your room dimensions ready. We will help you estimate the number of modules and plan the layout.
How many mats do I need for my room?
One 100x100 cm mat covers 1 m². Multiply the length of the room by its width, then allow a margin for cutting at walls, pillars and recesses. For 60x60 cm modules, the calculation is done separately for each dimension, rounding up.
Do the mats come with edge borders?
We include 4 edge borders with each 100x100 cm mat and 2 edge borders with each 60x60 cm mat. They close off the outer edges of the floor where it does not meet a wall.
What subfloor can the mats be laid on?
On a level, dry and hard subfloor such as concrete, screed, laminate or tiles. Unevenness and soft carpets can cause the joints to move.
How do I lay the mats and cut them at the walls?
Lay the modules in rows on a level subfloor and plan the cut pieces along walls and pillars. Leave a small expansion gap so the foam has room to move naturally. For larger rooms, it is worth sketching the colour layout beforehand.
Are the mats double-sided?
Yes. In two-colour versions each side has a different colour, so you can create your own compositions by flipping selected modules.
04 / CARE
Use and maintenance
A few simple care rules help keep the surface in good condition.
How do I clean and disinfect the mats?
For everyday cleaning use a mop, water and a mild detergent. Disinfectants should be intended for plastic surfaces. Avoid strong solvents and harsh chemicals.
Can I walk on the mats in shoes?
Clean sports footwear with a suitable sole can be used. Avoid spikes, sharp elements and footwear dirty with sand or gravel.
Can the mats be used under heavy equipment?
No. EVA foam mats are not intended for use under heavy machines, racks, heavy punch bags or equipment that applies point pressure over a long period. For such zones, choose suitable rubber flooring or another dedicated surface.
What should I do if the mats come apart at the joints?
Check that the subfloor is level and hard, that an expansion gap has been left at the walls, and that the open edges have been properly finished with edge borders.
GYM4 / CUSTOM FLOORING

05 / PERSONALISATION
Colours and NEO FLEX
Match the colour combination to your club's identity, the interior and the character of your training.
Can I order mats in my club colours?
Yes. Various colour combinations are available. We can help you choose a neutral base and colour accents that match your club's identity.
What is NEO FLEX?
It is a floor design concept based on a neutral base — most often black and grey — and bold colours placed irregularly. The layout is neither a chequerboard nor a repeating pattern. We tailor the design to the dimensions of the room and the chosen mat palette.
Can I see the colours before ordering?
For larger orders it is worth asking for colour samples, so you can compare the actual shades with your logo, walls and room lighting.
Can I buy the same mats again in the future?
The core colours are kept in the range. If you are extending an existing room, it is worth contacting us to confirm the availability of a specific combination.
