Quick Answer: If your feet do not rest flat on the floor when seated, a footrest is essential. The ErgoFoam Adjustable Footrest ($35) covers basic needs. For standing desks, the Topo anti-fatigue mat's contoured surface genuinely reduces fatigue compared to flat mats.

Footrests are one of the most overlooked ergonomic accessories. When seated, your feet should rest flat on the floor with your thighs parallel to the ground. If your chair is too high for your height (common when adjusting to desk height), your feet dangle — putting pressure on the backs of your thighs and reducing circulation. A footrest fixes this.

When standing, an anti-fatigue mat or active standing accessory reduces the strain of standing in one position for hours — an essential companion to any of the best standing desks of 2026.

Here is what to consider and which options are worth buying.

Why Footrests Matter

For Seated Work

If your desk is a standard 28-30 inches high, you need a chair height that places your arms at a 90-degree angle to the keyboard. For many people (especially those under 5'8"), this chair height leaves their feet short of the floor. The result:

  • Pressure on the backs of the thighs, reducing blood circulation
  • Increased lower back strain as your body compensates
  • Restless legs from lack of a solid resting position
  • General discomfort that builds over the day

A footrest raises the floor to your feet, restoring the ergonomic chain from feet through knees through hips through spine. Getting your chair dialed in first helps too — see our picks for the best ergonomic office chairs under $500.

For Standing Work

Standing in one position on a hard floor is nearly as bad as sitting all day. Your legs, feet, and lower back fatigue quickly. Standing accessories solve this by:

  • Cushioning the floor surface (anti-fatigue mats)
  • Encouraging micro-movements (balance boards, rocker boards)
  • Allowing alternating foot elevation (standing footrests)

Key features:

Best Standing Desk Accessories

Topo by Ergodriven

Topo is a standing desk mat with a contoured surface that encourages natural foot movement. Instead of a flat mat, it has bumps, ridges, and edges designed to prompt you to shift your feet, stretch your calves, and change positions throughout the day.

Key features:

  • Contoured surface with varied terrain
  • Power wedge for calf stretching
  • Massage mound for foot stimulation
  • Beveled edges that prevent tripping

Strengths: The non-flat surface genuinely encourages movement. Most people unconsciously shift their feet across the terrain, which reduces fatigue compared to standing on a flat surface.

Price: Around $99-120.

Best for: Standing desk users who want an active mat that encourages movement.

CubeFit TerraMat

CubeFit TerraMat is similar in concept to the Topo — a contoured anti-fatigue mat with raised edges, massage points, and a balance bar.

Key features:

  • Multiple terrain features
  • Balance bar for stretching
  • Power wedge
  • Anti-fatigue foam base

Price: Around $80-100.

Best for: Standing desk users who want varied terrain features at a slightly lower price than Topo.

FluidStance Level

FluidStance makes balance boards designed for standing desks. The Level is a deck that sits on a central fulcrum, allowing you to rock side to side while standing.

Key features:

  • Side-to-side rocking motion
  • Compact footprint
  • Multiple surface options (wood, aluminum)
  • Weight capacity up to 300 lbs

Strengths: Active balancing engages core and leg muscles, reducing the static nature of standing. The rocking motion is subtle enough not to be distracting.

Limitations: Not suitable for everyone — some people find the instability distracting or uncomfortable.

Price: Around $150-280 depending on material.

Best for: Active standers who want to engage muscles while working.

Basic Anti-Fatigue Mat

If you just need cushioning, a standard anti-fatigue mat works well. Brands like ComfiLife and Sky Solutions offer 3/4-inch thick mats in various sizes for $30-50. See our full guide to the best standing desk mats for more picks.

Best for: Budget standing desk users who need basic cushioning.

Choosing Between Seated and Standing Footrests

Seated Footrest Sizing

  1. Sit in your chair with your back against the backrest
  2. Adjust the chair height so your arms are at 90 degrees to the keyboard
  3. Check your feet — if they do not rest flat on the floor, measure the gap
  4. Choose a footrest that fills that gap with room for adjustment

Standing Mat Sizing

  • Width: At least as wide as your standing position (24 inches minimum, 30+ inches preferred)
  • Depth: 24-36 inches, enough to shift your weight without stepping off
  • Thickness: 3/4 inch minimum for effective cushioning

The Bottom Line

If your feet do not rest flat on the floor when seated, a footrest is not optional — it is essential for long-term comfort and health. The ErgoFoam covers basic needs for $35. The Humanscale FM 300 provides the best adjustable option. For standing desks, the Topo mat's contoured surface genuinely reduces fatigue compared to a flat mat. Start with whichever addresses your current setup — seated footrest or standing mat — and notice how quickly the discomfort you did not realize you had disappears.
