What Thickness Stable Mats Do I Need? UK Horse Owner Guide
Last updated: May 2026
For most horses in standard stable boxes, 17mm rubber stable mats provide the right balance of cushioning, drainage, and durability. Heavier horses (over 600kg), stud farms, or hard concrete substrates benefit from 22mm mats. This guide explains exactly what to choose — and why.
What Thickness Stable Mats Do I Need?
The recommended stable mat thickness is 17mm for most horses on standard concrete floors, and 22mm for heavy horses, pregnant mares, foaling boxes, or stables with no existing sub-base. Thicker mats provide better cushioning for joints and hooves, better insulation from cold concrete, and last longer under the weight and movement of horses.
Stable Mat Thickness Guide by Horse Type
| Horse Type / Situation | Recommended Thickness | Reason |
|---|---|---|
| Standard riding horse (400–600kg) | 17mm | Standard cushioning and durability |
| Heavy horse / Cob (600–800kg) | 22mm | Greater weight requires more compression resistance |
| Competition horse | 17–22mm | 22mm preferred for joint and hoof protection |
| Foaling box / pregnant mare | 22mm minimum | Additional cushioning for foaling; easier for foal to stand |
| Young horses / youngstock | 17mm | Standard specification appropriate |
| Stables with existing rubber underlay | 12–17mm top layer | Underlay adds effective depth; top layer protects and drains |
| Loose boxes (outdoor use) | 22mm EPDM | UV-resistant EPDM compound for outdoor exposure |
17mm vs 22mm Stable Mats: Full Comparison
| Feature | 17mm Stable Mat | 22mm Stable Mat |
|---|---|---|
| Weight per mat (standard 1.83×0.91m) | ~25–28kg | ~38–45kg |
| Cushioning level | Good | Excellent |
| Cold floor insulation | Good | Excellent |
| Suitable for horses over 600kg | Marginal | Yes |
| Ease of lifting to clean | Manageable | Heavy — may need 2 people |
| Typical price per mat | £35–55 | £55–80 |
| Lifespan (average use) | 8–12 years | 10–15 years |
Does Thicker Always Mean Better?
Not always. 22mm mats are heavier (approximately 38–50kg per mat) — significantly harder to lift for cleaning. For a standard horse on a smooth concrete floor, 17mm provides adequate cushioning. The key is covering the entire stable floor without gaps — thin mats fully covering the floor beat thick mats with gaps where the horse can reach concrete.
How Many Stable Mats Do I Need?
For a standard 3.6m × 3.6m (12ft × 12ft) stable box, you need approximately 13m² of matting. Standard stable mats measure 1.83m × 0.91m (6ft × 3ft), so you need 8–9 mats plus trim cuts for a complete fit. Always add 10% for cuts and waste.

Rubber vs EVA Foam Stable Mats — Which Is Better?
Rubber stable mats are significantly more durable and appropriate for horses than EVA foam alternatives. Rubber withstands horse hoof traffic, urine, ammonia, and the full weight of a horse lying down without permanent compression. EVA foam degrades quickly under equine conditions and needs replacing far more frequently. For genuine stable flooring, specify solid rubber mats only.
2026 Update: Stable Mat Innovations Worth Knowing About
The UK equestrian rubber matting market has seen several developments worth knowing when specifying stable mats in 2026:
- Interlocking stable mats: Jigsaw-edged rubber mats that click together without exposed seam gaps are increasingly available in 17mm and 22mm. They eliminate the urine seepage problem of butted-edge mats, reducing stable ammonia and bedding use. A worthwhile upgrade for high-value competition yards.
- Channelled drainage mats: Mats moulded with drainage channels underneath improve ammonia evaporation and airflow at floor level. Some livery yards report 25–35% reduction in bedding requirements — a significant saving at current straw prices.
- EPDM indoor stable mats: EPDM rubber is traditionally specified for outdoor use, but indoor EPDM stable mats are now available offering better compression recovery than SBR — useful for competition boxes where the floor is subject to intense scrutiny. At roughly 30% more per mat, EPDM is a specialist upgrade rather than a general recommendation.
Can I Use 12mm Stable Mats?
12mm rubber mats are too thin for primary stable flooring under most horses. They compress too easily under the weight of a horse lying down, offer insufficient cold floor insulation, and have a shorter service life under equine hoof traffic. 12mm is suitable as a secondary top-up layer over an existing rubber base, or for light applications like feed room or tack room flooring. For actual stable boxes, 17mm is the minimum recommended specification.
Can You Use Gym Mats as Stable Mats?
No — rubber gym mats are not suitable for stable use. Gym tiles and rolls are compounded for indoor foot traffic, not equine hoof traffic, urine, and the sustained weight of a lying horse. Gym mats compress permanently under repeated heavy loading and are not resistant to ammonia degradation. Additionally, gym mats typically have smooth surfaces not designed for drainage. Purpose-made rubber stable mats have a different compound specification and density profile for equine environments.
Tips for Laying Stable Mats
- Clean and level the concrete floor before laying — lumps under mats create stress points and uneven surfaces
- Butt mats tightly together — gaps allow urine to seep underneath, causing odour and floor damage
- Consider fitting mats against walls and in corners to prevent horses pulling at mat edges
- Leave a slight gap (2–3mm) at walls to allow thermal expansion — mats expand slightly in warm weather
- For maximum hygiene, lift and clean mats monthly, allowing the concrete underneath to dry thoroughly
Frequently Asked Questions
What is the best stable mat thickness for a 500kg horse?
17mm rubber stable mats are the standard recommendation for horses between 400–600kg. This provides adequate cushioning, joint protection, and insulation without the handling difficulties of 22mm mats.
Are 22mm stable mats worth the extra cost?
For heavy horses (600kg+), competition horses, pregnant mares, or foaling boxes — yes. The extra 5mm makes a meaningful difference to cushioning and lifespan under heavy use. For standard riding horses on concrete, 17mm is cost-effective and sufficient.
How often should I replace rubber stable mats?
Quality rubber stable mats last 8–15 years depending on thickness and horse weight. Replace when mats show permanent compression grooves (where horses stand repeatedly), cracking, or when they can no longer be butted together without gaps. Signs of ammonia degradation (softening or tackiness) also indicate replacement is due.
Do I need to stick stable mats down?
No — stable mats are designed to lay loose. The weight of the mats (25–50kg each) keeps them in place. Adhesive bonding is not recommended as it makes cleaning and replacement far more difficult. Interlocking borders or wall profiles can help keep edge mats in position.
Can stable mats be used outside?
Standard SBR rubber stable mats are for indoor use. For outdoor loose boxes, horse gateways, and exercise areas, specify EPDM compound (UV and weather resistant). SBR rubber can degrade in prolonged UV exposure outdoors.
What is the difference between stable mats and field mats?
Stable mats (17–22mm solid rubber) are designed for indoor stable use — cushioning, drainage, and insulation. Field mats or grass mats are typically open-grid rubber designed to prevent mud and poaching in outdoor areas like gateways and turnout areas. They serve different purposes and are not interchangeable.
How do I calculate how many stable mats I need?
Measure stable floor area in square metres (length × width). Divide by the mat area (1.83 × 0.91 = 1.67m² per standard mat). Add 10% for cuts and waste. A 3.6 × 3.6m stable = 13m² ÷ 1.67 = 7.8 mats, so order 9 (including waste).
Is 12mm thick enough for rubber stable mats?
No — 12mm is insufficient for primary stable flooring. It compresses too easily under horse weight, offers poor cold-floor insulation, and has a shorter service life. Use 12mm only as a supplementary layer over an existing rubber base. For new stabling, 17mm minimum is the correct specification.
Do stable mats reduce bedding requirements?
Yes. Good rubber stable matting reduces bedding use by 30–50% in many cases. The mats provide insulation, cushioning, and (if drainage-channelled) moisture management that straw or shavings would otherwise need to provide. The reduced bedding cost often offsets the mat investment within 12–24 months.
