The Complete Guide to Upholstery Fabric Symbols

Chosen theme: The Complete Guide to Upholstery Fabric Symbols. Decode the icons, care codes, and certifications that quietly dictate how your sofas, chairs, and cushions will live, age, and look—so you can clean confidently and style fearlessly.

Code W: Water-Friendly Cleaning

When you see W, you can generally use water-based cleaners and mild upholstery shampoos. Always spot-test in a hidden corner first, blot rather than rub, and work from the outside of a stain inward. Share your toughest water-safe stain stories with us, and subscribe for our downloadable blotting guide tailored to common upholstery fibers.

Code S: Solvent-Only Strategy

S calls for solvent-based cleaners—no water. Think dry-cleaning solutions and careful ventilation. Mist lightly, dab gently, and avoid oversaturation. Many vintage bouclé and linen blends carry S, so handle with patience. Ask us about your fabric’s fiber content in the comments, and we’ll suggest a safer solvent approach and a simple pretest protocol.

Code WS or X: Proceed With Nuance

WS permits either water-based or solvent-based cleaners, but with moderation and always after a patch test. X means vacuum or brush only—no liquids. It’s strict, but it saves texture and color. Tell us what code your sofa has, and we’ll send you a concise, code-matched cleaning checklist to keep on your toolkit shelf.

ISO Care Symbols on Removable Covers

A washtub icon indicates machine washing. Numbers or dots signal temperature, and lines underneath suggest gentler cycles. Even if the cover is washable, close zippers, turn inside out, and avoid overloading. Comment with your cover’s label, and we’ll help you interpret the temperature and cycle for minimal shrinkage and seam stress.

ISO Care Symbols on Removable Covers

The triangle governs bleach (empty for any bleach, crossed for none). A square shows drying: a circle inside means tumble, with dots for heat levels. The iron icon uses dots for temperature. Use mesh bags for delicate piping and low heat to protect nap. Subscribe to get our printable quick chart for laundry icons on upholstery covers.

Durability Icons: Martindale, Wyzenbeek, and Pilling

Martindale ratings express cycles before wear appears—20,000+ suits busy homes, 50,000+ aims at commercial use. A small abrasion icon or number often appears on spec sheets. If your sofa sees kids, pets, and popcorn nights, share your current rating and room usage; we’ll recommend ideal thresholds without sacrificing hand-feel.

Wyzenbeek numbers show double rubs—think back-and-forth motion. Residential comfort often starts around 30,000 double rubs, while heavy-duty can exceed 50,000. A tiny seat icon with a count may appear. Tell us your traffic level, and we’ll help translate numbers into real-life resilience while balancing texture, breathability, and color depth.

Pilling scales (often 1–5) and a fabric-ball icon predict fuzzing from friction. Blends with staple fibers can pill faster without proper twist or finish. If you have pets that love armrests, ask for our anti-pilling care routine and shaver recommendations—plus a fiber-content checklist for choosing smoother surfaces next time.

CAL 117-2013 and Related Labels

Look for a flame icon with text like CAL 117-2013, indicating compliance with California’s smolder resistance standard for upholstered furniture materials. It’s not a blanket guarantee of fireproofing, but it’s a meaningful baseline. Share your jurisdiction, and we’ll point to the standards most relevant to your project.

European Standards: BS 5852 and EN 1021

You may see references to BS 5852 or EN 1021-1/2. These tests simulate smoldering cigarettes and small flames. Some fabrics require specific interliners or foams to meet composite tests. Planning a hospitality project? Tell us your venue type, and we’ll suggest specification language that aligns with these symbols and local code advice.

Marine and Transport: IMO and Beyond

For boats or transport seating, look for IMO FTP Code Part 8 or similar marine icons. They indicate performance in harsh, regulated environments. If your project sees sunlight, salt, and motion, ask for our cross-check list that pairs fire labels with UV and mildew resistance to avoid premature failure at sea.

Colorfastness and Light Icons

A sun icon with a number often references Blue Wool scale ratings, where higher means better fade resistance. Near bright windows, aim higher or add UV-filtering shades. Share your room’s sun exposure, and we’ll suggest lightfastness targets and styling tricks to preserve saturated colors without living in the dark.

Pattern Direction, Railroading, and Repeat Symbols

An arrow running sideways can indicate railroaded fabric—great for wide, seam-free horizontal applications. Up-the-roll runs lengthwise. Knowing this prevents awkward seam placement on long sofas. Share your sofa width and fabric pick, and we’ll help decide orientation so stripes, herringbones, or textures fall exactly as intended.

Pattern Direction, Railroading, and Repeat Symbols

Grid or ruler icons with numbers show vertical and horizontal repeats. A half-drop symbol signals staggered alignment. Larger repeats need extra yardage for matching. Comment with your room dimensions, and we’ll estimate yardage that respects the repeat, ensuring motifs meet cleanly across cushions, arms, and backs.

Pattern Direction, Railroading, and Repeat Symbols

Arrows can also mark nap direction for velvets and chenilles. Cut pieces consistently to avoid shading differences between cushions. If you’ve lived with a sofa that looked two-toned by afternoon light, tell us about it, and we’ll share a cutting layout that aligns nap and lighting for visual harmony.

Sustainability and Health Badges

OEKO-TEX and REACH: Safer Chemistry

OEKO-TEX Standard 100 labels reduce the risk of harmful substances, while REACH compliance indicates responsible chemical management. These badges help families with sensitivities breathe easier. Ask which symbols your shortlist carries, and we’ll send our chemical-safety cheat sheet to pair comfort with peace of mind.

GREENGUARD Gold and Low-VOC Claims

Indoor air certifications signal low emissions from fabrics and finishes. GREENGUARD Gold is a common marker for healthier interiors, especially vital in nurseries or compact spaces. Tell us your room size and ventilation, and we’ll recommend combinations that balance durability with the cleanest air profile possible.
