For high-pile carpeting, we recommend our Mercury-style single-wheel casters with 2½" tapered hard wheels for smooth, stable rolling.

If your carpet is extra dense or has soft padding, pair your chair with a chair mat or choose soft-wheel casters to make movement easier.

Hard wheels (nylon, vinyl, hard plastic) are for carpeted surfaces.

Soft wheels (urethane or soft rubber) are for hard floors, tile, linoleum, and chair mats.

Using the wrong wheel type can cause sliding, muscle strain, or even safety hazards. Learn more in our Caster Selection Guide →

Incorrect casters can cause chairs to roll too fast on hard floors or resist movement on carpet, leading to accidents or muscle strain. Always match wheels to the floor surface:

• Hard wheels → carpet

• Soft wheels → hard floors and mats

And replace all casters at the same time for balanced rolling.

Most office chairs (about 99%) use a Grip Ring Stem B (7/16" x 7/8") or Stem K.

If your chair has a wood base, choose W stems with sockets instead.

Tip: Always check your chair base style before ordering to ensure the perfect fit. Shop by Stem Type →

Most office chairs (about 99%) use a Grip Ring Stem B (7/16" x 7/8") or Stem K.

If your chair has a wood base, choose W stems with sockets instead. When removing old wood stem casters, the sockets often stretch and need replacing but don’t worry!

All new Master Manufacturing “W” stem casters come with replacement sockets included at no extra cost.

Tip: Always check your chair base style before ordering to ensure the perfect fit.

Standard necks (5/8") fit all standard chair bases.

Oversized necks (1-1/2") are used in Euro-style chairs to make the base and caster appear as one.

Casters come in multiple finishes:

• Zinc (ZN)

• Matte Black (MB)

• Bright Chrome (BC)

• Satin Chrome (SC)

• Bright Nickel (BN)

• Brass

• Antique Copper

Yes. Some 2" standard casters are available in grey non-marking wheels, but most dual-wheel casters remain black. This is to ensure universal compatibility with chair bases.

Try this simple test: Hold the caster and press your fingernail into the wheel.

• If it gives slightly, it’s soft.

• If it’s firm with no give, it’s hard.

Safe chair movement requires the right balance of traction, depending on floor type.

Hard wheels (nylon, hard rubber, vinyl) are best for carpet and soft flooring.

Soft wheels (rubber or urethane) work best on hardwood, tile, mats, or linoleum, providing grip and preventing scratches.

Choose soft wheels for wood, tile, or linoleum. They provide smoother, safer movement and protect your floors.

Hard wheels roll faster but may crack or damage hard surfaces over time.

Yes, thanks to improved materials, black wheels no longer mark floors.
For extra peace of mind, the 2" single-wheel caster is also available in a gray non-marking version.

Any soft wheel caster will work on light colored tile or linoleum.

Casters roll and glides don’t.

Glides are stationary and work best if you want to convert a chair into a fixed base (no wheels). They’re ideal for classrooms, conference rooms, or workspaces where stability matters more than mobility.

Wipe casters and glides regularly to remove dust and debris.

• Never use harsh chemicals; a damp cloth is sufficient.

The lifespan of casters or glides depends on how often they’re used and the type of flooring.

• Heavy commercial use: may need replacement every 1–2 years.
• Light or home use: can last much longer with proper care.

Tip: Always replace all casters or glides at the same time to keep your furniture balanced and rolling smoothly.
