Adjustable leveling feet solve the most common furniture problem: a rocking leg that concentrates load on one point instead of distributing it evenly, wearing through pads and scratching floors faster than a level piece ever would. This guide covers how to choose the right type, measure your thread size and tube diameter, select the right base material, and install correctly. Whether you are fitting a kitchen cabinet, a commercial workstation, or a restaurant table, you will find the right foot here.
Not sure if you need leveling feet? Leveling feet are for hollow tube furniture legs that accept a threaded rod.
If your floors are uneven and you need floor protection without height adjustment, you need Furniture Pads. If your furniture has hollow tube legs that need sealing, you need Tube Plugs. Outfitting a hotel, restaurant, or commercial space? See our Business Solutions page.

Three measurements determine the right adjustable leveling feet for your furniture: base diameter, thread size, and rod length. Getting all three right means the foot fits the furniture, grips the floor, and provides the adjustment range you need.
Measure the outer diameter of the existing foot or the tube end. Base diameters in the catalog range from Ø 13 mm (mini) to Ø 50 mm (wide-base). Larger bases distribute load over a wider area and resist tipping on uneven floors.
Thread size (M4, M6, M8, M10, M12) refers to the outer diameter of the threaded rod. M8 is the most common for commercial furniture. M4 and M6 suit lighter pieces. M10 and M12 handle heavy-duty industrial applications. All catalog leveling feet use standard metric thread pitch as defined in ISO 965 metric screw threads. Imperial thread sizes (1/4‑20 and 5/16‑18) are available on the Standard Base with Pad version for North American furniture.
Rod length is the threaded section that inserts into the furniture leg. Longer rods allow more height adjustment. Most catalog sizes run 10–70 mm. Measure the depth of the threaded insert in your furniture leg to ensure the rod engages fully.
The threaded rod inserts inside the tube. Measure the inner diameter of the tube to confirm the rod will fit. M8 rod requires at least 8 mm inner clearance. Most standard furniture tube legs comfortably accept M6–M10 rods.
Standard metric thread pitch is 1.25 mm for M8 and 1.5 mm for M10. All catalog leveling feet use standard metric pitch unless otherwise noted. Inch thread sizes (1/4–20 and 5/16–18) are available on the Standard Base with Pad version for North American furniture.
Measure the floor slope or gap at the shortest leg. The leveling foot needs a rod long enough to bridge that gap plus engage the tube fully. Most floors require 5–15 mm of adjustment. Severely uneven floors or outdoor use may need longer rods.
The base pad must sit flat on the floor when the foot is at mid-adjustment. If the furniture frame sits too low, the base may contact the frame before the pad contacts the floor. Check clearance before ordering tall-rod versions.
M4 (light residential, small side tables) · M6 (standard residential, dining chairs with tube legs) · M8 (standard commercial, most dining and cafe furniture) · M10 (heavy commercial, workstations and shelving) · M12 (industrial, heavy shelving and equipment stands). When in doubt, choose M8.
Two decisions determine the right adjustable leveling feet for any application. First: what base size and style does the furniture need? Second: does the floor require a PA6 floor-protection pad on the base face? Answer both and the correct catalog entry is clear.
Base diameters of Ø 30–45 mm cover the majority of residential and commercial furniture. Standard base (Type A) and Low-Profile base (Type E) share the same footprint but differ in body height.
Standard base (Type A): Taller body, visible above floor level. M6–M12 thread options. Suits most dining, cafe, and commercial seating.
Low-Profile base (Type E): Shorter body that sits close to the floor. Preferred when foot visibility is a concern. M4–M10 options.
Specialty bases suit applications where the standard Ø 30–45 mm range does not provide enough stability, is too large, or where the environment demands a specific material.
Wide base (Ø 50 mm): Maximum load distribution. Best for heavy furniture, uneven floors, or outdoor surfaces. TPE anti-slip version available.
Mini base (Ø 13 mm, POM): For light furniture with small tube legs. M4 and M6 only. POM material instead of PA for smaller form factor.
Quick rule: If the furniture is commercial or seats people, use M8 minimum with a Ø 30 mm or larger base. If the floor is uneven by more than 10 mm, choose a longer rod version.
If the foot will be visible on a finished floor, choose the PA6 pad version for floor protection.
A permanently bonded PA6 needle-punched fiber pad is integrated into the base. The same PA6 material used in our furniture glides. Protects hardwood, tile, vinyl, and laminate from the base edge.
Best for: Any furniture on hard floors where bare PA or TPE base contact is not acceptable. Especially important for polished hardwood and large-format tile.
Available on: Standard Base (Type A with pad), Low-Profile Base (Type E with pad). Pad slot versions also available on selected tube plug types for sled base furniture.
Standard PA or TPE base contacts the floor directly. PA is smooth and hard. TPE (anti-slip wide base) grips the floor to prevent movement. Neither damages hard floors under normal static load.
Best for: Outdoor, industrial, or commercial environments where pads would degrade. Also suitable for rubber or textured flooring where the PA6 pad gliding property is not needed.
Note: On polished hardwood or sensitive floors, the with-pad version is strongly recommended to prevent base edge marking under sustained load.
Hex-key and notched versions: Some foot types include a hex socket or screwdriver notch in the threaded rod for precise height adjustment with a tool rather than by hand. The Smooth-Base Hex-Key and Notched Thread versions are the most common for cabinets and built-in furniture.
Seven adjustable leveling feet types cover every residential and commercial application. Each type has a distinct body shape, thread range, and base size. Match the type to the furniture frame and floor condition.
Standard Base (Type A)
The most common leveling foot. PA base (Ø 30 or 45 mm) with galvanized steel threaded rod. Available in M6–M12. Rod lengths from 10–63 mm. With or without integrated PA6 pad. Colors: Black, Grey, White.
Low-Profile Base (Type E)
Shorter body profile for applications where foot visibility matters. PA base (Ø 20–30 mm) with Fe HDG rod. M4–M10 thread range. Rod lengths from 8–50 mm. With-pad version available in Ø 30 mm M8.
Ultra-Low Profile (Type E-L)
The lowest body height in the range. Ø 25 mm base. M8 and M10 thread only. Suited to furniture where the foot must be nearly invisible at floor level.
Wide Base (Type M)
Ø 50 mm base for maximum load distribution. Available in standard PA and TPE anti-slip. M8 thread. TPE version grips the floor and prevents furniture movement without additional fixings.
Mini Base (Type P)
POM (polyoxymethylene) base at Ø 13 mm. The smallest foot in the range. M6 thread only. POM provides the rigidity needed at this scale without the bulk of a PA base. For light residential furniture with small tube legs.
Self-Leveling Tilt (Ball Joint)
PA base (Ø 10 or 35–48 mm) with a half-sphere head that auto-levels to minor floor irregularities. No manual adjustment needed. Best for furniture placed on textured or slightly uneven surfaces where manual leveling is impractical.
Stainless Steel Rod Versions
Standard PA base with INOX (stainless steel) threaded rod instead of Fe HDG. For outdoor, marine, wet-room, and high-humidity environments where galvanized iron rod corrosion is a concern. Available in Ø 30 and 45 mm bases.
Thread size, base diameter, and rod length for adjustable leveling feet vary across furniture categories. Use this section to find the right spec for your piece directly.
Tube legs with M6 or M8 thread. Low-Profile Type E base is the most common choice because the foot sits close to the floor and is nearly invisible under the leg. Ø 20–30 mm base. With-pad version recommended on smooth, hard floors. Notched thread version for restaurant chairs that are repositioned frequently.
Typical spec: M8 × 14–28 mm rod, Low-Profile Type E, Ø 30 mm base.
Typical spec: M8 × 14–28 mm rod, Type E, Ø 30 mm base.
Heavier load than seating. M8 or M10 thread. Standard base (Type A) for most dining tables. Wide base (Ø 50 mm) for heavy marble or stone tops where load concentration is a concern. PA6 pad version strongly recommended to prevent base edge marking on polished floors.
Typical spec: M10 × 28–43 mm rod, Standard Base Type A, Ø 45 mm base.
Typical spec: M10 × 28–43 mm rod, Type A, Ø 45 mm base.
Higher centre of gravity increases lateral load on each foot during use. Choose M8 minimum. Standard or low-profile base depending on visibility requirement. With-pad version for smooth, hard floors. Extended rod length (43–63 mm) for countertop-height stools with longer legs.
Typical spec: M8 × 28–43 mm rod, Standard Base Type A or Low-Profile Type E, Ø 30–45 mm base.
Typical spec: M8 × 28–43 mm rod, Type A or E, Ø 30–45 mm base.
High static load from seating plus dynamic load from users sitting down. M10 or M12 thread. Standard base Type A at Ø 45 mm. Notched thread version for fixed commercial installations where vibration from foot traffic could loosen a standard rod over time.
Typical spec: M10 × 28–50 mm rod, Standard Base Type A, Ø 45 mm base.
Typical spec: M10 × 28–50 mm rod, Type A, Ø 45 mm base.

Typical spec: M8–M10 × 28–43 mm, Smooth-Base Hex-Key or Notched Thread Standard Base.
Typical spec: M8–M10 × 28–43 mm, Smooth-Base Hex-Key or Type S.
High combined load from contents plus frame. M10 or M12 thread. Wide base (Ø 50 mm) if unit is freestanding on smooth, hard floors to prevent rocking and base-edge floor marking. Stainless steel rod for pantry, laundry, and food-prep environments.
Typical spec: M10–M12 × 25–45 mm, Standard Base Type A or Wide Base Type M, Ø 45–50 mm base.
Typical spec: M10–M12 × 25–45 mm, Type A or M, Ø 45–50 mm base.
Stainless steel rod (PA + INOX) versions resist salt spray and moisture. PA base is UV-stable and humidity-stable for covered outdoor use. TPE wide base (anti-slip) resists moisture-related movement on wet terrace surfaces. Specify INOX rod for any direct exposure to rain, sea air, or cleaning chemicals.
Typical spec: M8 × 24–28 mm, PA + INOX rod, Ø 30–45 mm base.
Typical spec: M8 × 24–28 mm, PA + INOX, Ø 30–45 mm base.
Typically installed before the plinth panel is fitted. The foot is hidden once the plinth is in place. Notched thread or Smooth-Base Hex-Key version allows height adjustment after the plinth is fitted, using a flat-head screwdriver or Allen key through a small access slot.
Typical spec: M8 × 14–35 mm, Smooth-Base Hex-Key or Notched Thread Standard Base.
Typical spec: M8 × 14–35 mm, Type S or Smooth-Base Hex-Key.
Every pair of adjustable leveling feet is an engineered system combining a floor-contact base, a load-rated threaded rod, and the right material for the environment. The base material determines grip, floor protection, and load distribution. The rod material determines corrosion resistance and load rating.
Three material combinations cover every residential and commercial application. PA + Fe HDG is the standard. POM suits the mini range. INOX rods handle outdoor and marine environments.
PA (polyamide) base with Fe HDG (hot-dip galvanized) threaded rod. PA provides rigidity, impact resistance, and chemical stability across the full temperature range (−40°C to +85°C). Fe HDG rod is load-rated for sustained static loads. Available across Standard Base, Low-Profile, Wide Base, Slim, and Smooth variants. Static load: 60–200 kg per foot depending on thread size. Colors: Black, Grey, White.
POM (polyoxymethylene) base with Fe HDG rod. POM is harder and more dimensionally precise than PA at small scales, making it the correct material for the Ø 13 mm Mini foot. Available only on Mini base (Type P). M6 thread. For light residential furniture with small tube legs.
TPE (thermoplastic elastomer) base with Fe HDG rod. TPE provides a high-friction floor contact surface that grips smooth, hard floors without adhesive. Available on Wide-Base Anti-Slip only. Ø 50 mm / M8. For heavy equipment that must hold position.
PA base with stainless steel (INOX) threaded rod. Identical base to the standard PA + Fe HDG version, but the rod resists salt spray, humidity, and cleaning chemicals. Available in Ø 30 and 45 mm bases, M6–M10. For outdoor furniture, marine environments, wet rooms, and food-prep applications.
Adjustable leveling feet are threaded in by hand. No drilling, no adhesive, no special tools for most types. The whole process takes under two minutes per foot once you have the right size.
Insert the threaded rod end into the tube leg opening. Turn clockwise by hand until the rod engages the thread. The rod should turn smoothly with no binding. If it binds immediately, confirm the thread size matches the tube insert.
Thread the foot in until the base pad is approximately 5 mm from the floor. Place the furniture on its feet and check which legs are not contacting the floor. Adjust each foot individually until all four bases make firm contact.
Use a spirit level on the furniture top surface. Turn each foot clockwise to raise that corner, counter-clockwise to lower it. Each full rotation moves the foot approximately 1–2 mm depending on thread pitch. Work diagonally, not side to side.
Apply firm downward pressure to each corner and check for rocking. If any rocking remains, fine-adjust the foot at that corner. All four bases should contact the floor simultaneously with no movement under load.
Thread the foot into the tube leg before fitting any skirting or plinth panels. Hex-key and notched versions are designed to be adjusted after the plinth is in place through an access slot in the plinth panel.
Turn the foot by hand to approximately the right height before fitting the furniture in position. Getting close by hand first reduces the adjustment needed through the access slot.
Insert a hex key (for hex-key version) or flat-head screwdriver (for notched version) through the plinth access slot. Turn to raise or lower the foot until the unit is level. Check with a spirit level on the top surface.
Test for rocking after all four feet are set. A correctly leveled unit should not rock under applied pressure at any corner. Recheck after 24 hours as slight settling can occur on carpet or soft flooring under initial load.
Generic adjustable leveling feet sold in hardware stores use thin-wall PA bodies and undersized rods that deform under sustained commercial load. Superior Glide adjustable leveling feet are specified to commercial furniture standards with load ratings per individual foot, not per set. Commercial load ratings reference BIFMA G1 stability and structural testing standards for commercial seating and tables.

Everything buyers need to know before choosing adjustable leveling feet for furniture.
Type A (Standard Base) has a taller body and is the most common commercial choice. Type E (Low-Profile Base) has a shorter body that sits closer to the floor, preferred where the foot will be partially visible. Both are available in Ø 30 and 45 mm bases with similar thread ranges. Type E also has a with-pad version available.
The thread size must match the threaded insert already in your furniture leg, or the inner diameter of the tube if you are threading directly. M8 is the most common for commercial furniture. If you are unsure, measure the inner diameter of the tube: M8 requires at least 8 mm clear bore, M10 requires at least 10 mm. The rod should turn smoothly with no binding when inserted.
On hardwood, tile, laminate, and vinyl floors, the PA6 pad version is strongly recommended. The bare PA or TPE base will not scratch most floors under normal conditions, but the PA6 pad eliminates any risk and provides the same smooth-glide surface used in our furniture glides. On outdoor, rubber, or textured flooring, the standard version without pad is fine.
Load rating varies by thread size: M6 handles approximately 60 kg per foot, M8 approximately 80 kg, M10 approximately 120 kg, and M12 approximately 200 kg. These are sustained static load ratings. Dynamic loads (furniture being sat on, drawers being opened) should use a safety factor of at least 2×. A four-leg dining table with M8 feet is rated at 4 × 80 = 320 kg total.
Any application with regular moisture exposure: outdoor furniture, marine furniture, bathroom vanities, kitchen islands near wet areas, food-prep workstations, and commercial kitchens. The standard Fe HDG (hot-dip galvanized) rod handles occasional moisture and covered outdoor use well, but direct salt spray or sustained wet exposure will cause surface corrosion over time. Specify INOX rod for these environments.
The hex-key version has a socket in the top of the threaded rod that accepts a standard hex key (Allen key). This allows height adjustment after the plinth or skirting panel is fitted, by inserting the key through a small access slot in the panel. It is the standard choice for kitchen cabinets, bathroom vanities, and any built-in furniture where the feet will be hidden behind a plinth.
Leveling feet are not designed for carpet. The base pad sits on the surface and the threaded rod adjusts height. On carpet, the base sinks into the pile and adjustment range is consumed by the carpet depth rather than floor level correction. On carpet, use furniture glides or slides depending on whether the furniture moves or stays in place.
The self-leveling tilt foot (ball-joint version) has a half-sphere head that tilts to match minor floor irregularities automatically without manual adjustment. It is best used where the floor slope is consistent and gradual — such as a slightly sloped concrete slab — rather than where individual legs need different heights. For furniture with significantly uneven leg lengths, manual adjustment with a standard leveling foot is more precise.
