Worsted Wool vs. Traditional Woolen Felt: The Physics of True Roll
To appreciate why Simonis cloth commands a premium price, you must understand the textile difference between standard woolen felt and worsted wool cloth. Cheap pool tables come covered in ‘napped’ woolen felt (a blend of short, scrambled wool fibers and synthetic polyester). Woolen felt has a fuzzy, carpet-like surface texture. When a 6-ounce cue ball rolls across napped felt, the loose surface hairs create high friction, dampening ball speed and causing slow-rolling balls to drift off course along the grain of the nap.
Simonis worsted cloth is manufactured using a specialized combing process that aligns long, premium wool fibers into tightly twisted yarns before weaving. The result is a completely flat, nap-free, shearing-resistant surface. Balls roll with pure hydrodynamic precision: there is zero directional nap to steer the ball off line, zero pilling or shedding of felt lint into pocket tracks, and maximum preservation of rotational spin across multi-rail position routes.

In-Depth Comparison: Simonis 860 vs. Simonis 760
1. Fabric Blend & Textile Density
The core structural distinction between these two legendary cloths is the proportion of synthetic nylon blended with combed worsted wool:
Iwan Simonis 860: Woven from 90% worsted wool and 10% nylon with a substantial fabric density of 410 g/m² (grams per square meter). The higher wool ratio gives the fabric a rich, velvety body that provides substantial grip against the spherical phenolic resin of the cue ball.
Iwan Simonis 760: Features a 70% combed wool and 30% nylon blend, with a lighter weight of 355 g/m². The higher 30% nylon content creates a tighter, slicker surface with a high-sheen finish that offers substantially lower friction against rolling balls.
2. Ball Speed and Table Pace
Table speed dictates how much physical stroke effort you must invest to move the cue ball around the table:
Simonis 760 (The Speed Demon): Simonis 760 is roughly 15% to 20% faster than 860. On a 9-foot table covered in 760, a gentle, smooth stroke sends the cue ball effortlessly three rails around the table. For players with compact strokes or those who play on tight 7-foot bar boxes where cluster breakouts require explosive cue ball speed, 760 makes the table feel lightning fast and reduces arm fatigue.
Simonis 860 (The Controlled Tournament Pace): Simonis 860 is universally designated as the official cloth of the WPA World 9-Ball Championships, US Open, and Mosconi Cup. While significantly faster than any woolen felt, 860 provides controlled deceleration. When you strike a delicate safety or position shot into a tight landing window between two traffic balls, 860 stops predictable without excessive sliding or rolling out of position.
3. English Response, Draw Bite & Cushion Rebound
How the cloth interacts with cue ball spin is where the two models diverge sharply:
Spin Grip on Simonis 860: Because of its 90% wool content, Simonis 860 allows the cue ball to bite aggressively into the cloth bed. When executing a low draw shot, the backspin grabs the cloth instantly, causing the cue ball to check up and zip backward across the table like it is on a string. On extreme side english shots, the ball holds its spin longer, kicking off cushions with sharp, predictable diamond angles.
Skid and Slide on Simonis 760: On Simonis 760, the high nylon content makes the surface slicker. When you apply heavy backspin, the cue ball tends to skid forward several inches further before the backspin finally catches the cloth. For players who love playing high-speed 8-ball and straight pool where balls are rolled with center-ball hits, 760 is magnificent; however, finesse players who rely on delicate screw-back position play often find 760 difficult to control.
Simonis 860HR (High Resistance): The Modern Hybrid Solution
In response to powerful modern break cues that smash balls at 30+ mph, Simonis introduced Simonis 860HR (High Resistance). When a phenolic tip strikes a cue ball at high speed, the momentary friction creates extreme heat (up to 480°F at the contact point), leaving small white friction burn marks on standard cloth.
Simonis 860HR retains the exact 90/10 wool-nylon blend and 410 g/m² tournament weight of standard 860, but incorporates a proprietary heat-resistant treatment that prevents ball burn blemishes. For commercial pool rooms, passionate league players who practice power breaks daily, or home table owners who want pristine cloth aesthetics for years, 860HR represents the ultimate modern investment.
Installation Protocols: Why Tension Stretch Dictates Performance
Even the finest Belgian worsted cloth will play poorly if installed incorrectly. Installing Simonis requires a completely different technique than cheap woolen felt:
The Drum-Tight Stretch Mandate: Simonis cloth is engineered to be stretched tightly across the slate bed in both length and width. When properly installed by an experienced billiard technician, the cloth should be stretched until it is as tight as a drum head. If Simonis is installed loosely like felt, balls will roll sluggishly, leave tracking indentations, and wear prematurely.
Gluing vs. Stapling: On wood-backed slate, technicians use heavy-duty pneumatic staples, pulling the cloth with immense hand tension before securing. On frameless solid slate beds, high-strength contact spray adhesive (such as 3M Fastbond or specialized billiard spray cement) is applied along the slate edges. Never apply glue across the playing surface; glue is applied strictly along the outer vertical slate perimeter.
Daily Care, Brushing and Vacuuming Guidelines
To preserve the slick rolling speed and rich color of your Simonis cloth for a decade, follow these non-negotiable maintenance rules:
1. Use a Horsehair Billiard Brush Correctly: Brush the table regularly using a genuine horsehair or fine synthetic billiard brush. Always brush in one direction—from the head string toward the foot rail (racking zone). Never brush in circular scrubbing motions or across the table width, which disturbs the combed weave.
2. Vacuum with Brushless Attachments Only: Chalk dust is composed of abrasive silica minerals that settle deep into the cloth weave, acting like sandpaper against rolling balls. Vacuum your table weekly using an upholstery vacuum attachment with a smooth, brushless nozzle. Never use a vacuum with a rotating beater brush, which will snag and tear the delicate worsted wool threads.
3. Keep Covered When Not in Play: Airborne dust, ambient humidity, and ultraviolet sunlight degrade wool fibers over time. Always drape a heavy-duty fitted vinyl table cover over your pool table whenever it is not in active use.
The Final Verdict: Which Cloth Should You Buy?
Buy Simonis 860 (or 860HR) If: You play competitive 9-ball, 10-ball, or 8-ball, demand authentic tournament conditions matching professional tour standards, and rely on pinpoint cue ball position play with heavy draw and english.
Buy Simonis 760 If: You own an 8-foot or 9-foot table in a casual recreational setting, play straight pool or one-pocket where effortless multi-rail glide is prized, or want maximum long-term fabric durability against heavy commercial use.
Room Humidity and Temperature Impacts on Worsted Wool Friction
Because worsted billiard cloth contains high percentages of natural sheep’s wool (90% in Simonis 860 and 70% in Simonis 760), the fabric is hydroscopic, actively absorbing and releasing atmospheric moisture based on room humidity. Understanding environmental humidity dynamics is essential for maintaining consistent tournament ball roll:
High Humidity Drag (>60% Relative Humidity): In damp basements or during muggy summer months, wool fibers absorb microscopic water droplets from the air, swelling in diameter and increasing rolling resistance. Cue ball rolling speed drops by up to 20%, draw shots require significantly more physical stroke power to execute, and cushions feel sluggish. Pool rooms with Simonis cloth should maintain climate-controlled environments with relative humidity between 40% and 50% using a dedicated dehumidifier.
Dry Winter Conditions (<30% Relative Humidity): In winter with dry furnace heat, worsted cloth dries out completely, becoming exceptionally fast and prone to static electricity build-up. While balls glide effortlessly across three rails, excessive dryness increases chalk dust adhesion. Brushing with a horsehair brush after every match prevents static-charged chalk particles from grinding into the weave.
Re-Covering Procedures: Slate Seam Waxing & Featherstrip Fitting
Recovering a billiard table with Simonis cloth requires precision craftsmanship. Unlike stretchy cheap felt, worsted wool has limited directional elasticity and must be fitted systematically:
1. Slate Seam Preparation: Before unrolling new cloth, inspect the three pieces of precision-ground slate. Fill all seam joints, screw countersinks, and microscopic slate chips with quick-drying billiard beeswax or two-part polyester rock putty. Scrape the seams perfectly flat using a 12-inch razor blade straightedge until you feel zero transition lip with your fingertips. Any tiny ridge under worsted cloth will deflect rolling balls.
2. Uniform Index Stretch: Lay the bed cloth face-up (identifiable by the subtle embossed Simonis script printed on the edge). Staple or glue the head string side first, then pull with maximum uniform body weight toward the foot end. Once longitudinal tension is locked, pull outward toward the side pockets in an index pattern, eliminating any diagonal wrinkles before securing the perimeter.
3. Cushion Rail Featherstrips: When covering the six cushion rails, tap the wood featherstrip into the rail channel with even hammer taps. Ensure the cloth wraps tightly around the rubber nose without stretching the cushion profile downward, maintaining ITTF/BCA regulation 63.5% ball bounce height off the rail rubber.
Chalk Dust Infiltration and Cloth Longevity Maintenance
A major cause of premature cloth wear is chalk dust grinding. Billiard chalk contains abrasive aluminum oxide and silica particles that fall onto the slate bed during bridge play. When 6-ounce phenolic balls roll over chalk dust under heavy downward stroke pressure, the abrasive dust acts like microscopic sandpaper, cutting through worsted wool threads.
Never chalk your cue directly over the table bed. Always step away from the table or chalk while holding your cue tip outward over the floor. Additionally, vacuum the table weekly using a smooth brushless upholstery attachment to extract settled chalk dust from deep within the wool weave, ensuring your Simonis cloth maintains its pristine playing surface for years.
Diamond System Banking Calibration on Simonis Cloth
When playing on championship worsted cloth, standard diamond banking systems require subtle mental adjustments compared to slow woolen felt. Because Simonis 860 and 760 produce minimal drag, banked balls maintain higher kinetic velocity into cushion noses, rebounding at slightly wider reflection angles. Spend 30 minutes practicing two-rail kick shots to recalibrate your diamond sighting lines before competitive tournament play.
Spotting and Triangle Burn Prevention
Repeatedly dropping heavy wooden or plastic racking triangles onto the cloth bed causes friction rings. Always place a clear plastic racking template or a paper reinforcement ring on the foot spot, and lift the triangle vertically rather than dragging it across the head rail to preserve the virgin cloth surface.
Thermostatic Cloth Ironing Protocol
In high-stakes professional tournaments, tables covered with worsted wool cloth are regularly ironed using dedicated thermostatic billiard irons. Unlike domestic steam irons (which introduce damaging hot moisture that warps the slate and softens adhesives), professional billiard dry irons maintain a steady temperature of 140°F (60°C). Moving the iron smoothly from the head rail to the foot rail in continuous, parallel strokes lays any microscopic surface fibers flat, eliminates moisture pockets, and increases ball velocity by 10% to 15% across the bed.
Break Pad Protection Against Kinetic Friction Burns
When an aggressive break shot launches the cue ball at 25 to 30 miles per hour, the downward stroke pressure presses the ball into the slate with immense force. The instantaneous friction between the 6-ounce phenolic ball and the worsted cloth generates localized temperatures exceeding 400°F (204°C), causing white burn marks called micro-pitting. Using a 4-inch square sacrificial break cloth remnant or a thin polymer break mat beneath the cue ball absorbs this thermal energy, protecting your primary bed cloth from premature wear.
