Key takeaways
- Length — front to back along the top of the armrest pad.
- Width — side to side at the widest point. Many armrests taper toward the front, so check both ends.
- Circumference — wrap the tape around the armrest’s cross-section (width plus top and bottom thickness) at its fattest point, usually mid-pad. This is the number elastic sleeves live or die by.
- Underside access — flip the armrest up or recline the chair and look underneath. Two or four Phillips screws mean you could install a replacement pad; no screws means the top is glued or riveted and covers are your only option.
What's inside
Measure your armrest’s length, width, and—most importantly—its cross-section circumference, then buy a cover whose stretch range matches that circumference; for most gaming chairs with 9–12 inch armrests, an elastic or zippered slip-on handles protection, while strap-on memory foam pads are the right pick when elbow comfort is the actual goal. The sections below walk through the measuring, the material trade-offs, and the three installation styles so you don’t end up with a sleeve that won’t stretch or a pad that pushes your elbows into your desk.
Measure Before You Buy: The Three Numbers That Matter
Gaming chair arm rest covers are sold by size range, not by chair model, so guessing is how people end up with sleeves that sag or rip at the seam. Grab a soft tailor’s tape (or wrap a piece of string and measure it against a ruler) and record:

| Measurement | Typical gaming-chair range | What it determines |
|---|---|---|
| Pad length (front to back) | 9–11.5 in (23–29 cm) | Cover length — most sleeves are rated for 9–12 in |
| Pad width (widest point) | 2.75–4 in (7–10 cm) | Whether a flat-knit sleeve will lie smooth |
| Cross-section circumference | 7–10 in (18–25 cm) | Elastic sleeve fit; over ~10 in, choose a zippered or strap style |
| Front-to-rear taper | Up to ~0.75 in width difference | Past ~0.5 in of taper, elastic sleeves bunch or creep; pick zippered |
| Screw spacing (if pad is removable) | Two-hole pattern, varies by brand — often ~4–7 in center-to-center | Whether universal screw-on pads will bolt up (most use elongated slots covering roughly this range) |
One more measurement people forget: floor to the underside of your desk. On standard 28–30 in desks with an apron or drawer unit, that’s commonly only 24–27 in. If your armrest tops already sit within an inch of that figure, skip thick foam pads — they’ll make the armrests jam against the desk edge every time you pull in close.
Fabric vs. PU Leather vs. Memory Foam: The Real Trade-Offs
Material is where a product listing tells you almost nothing. Each type solves a different problem and fails in a different way:
| Cover type | Typical build | Best for | Weak point | Care | Usual price (pair) |
|---|---|---|---|---|---|
| Stretch fabric sleeve | 1–3 mm polyester-spandex or jacquard knit | Sweaty hands, hot rooms, hiding light scuffs | Adds almost no cushioning; elastic hem loosens after ~a year of washing | Machine wash cold, air dry | Usually under $20 |
| Velour / plush sleeve | Soft pile knit over stretch backing | Softest feel against bare forearms | Pills over time and traps pet hair | Machine wash cold | $15–25 |
| PU leather sleeve | Thin polyurethane over knit backing, elastic or zippered | Invisibly covering a peeling stock armrest | Peels itself in roughly 6–18 months; traps heat and sweat | Wipe only | $15–25 |
| Memory foam strap-on pad | 1–1.5 in foam slab in a removable fabric cover, velcro straps | Elbow, forearm, and ulnar-nerve pressure relief | Adds 1+ in of height; straps loosen and need re-tightening | Wash the cover, spot-clean the foam | $15–30 |
| Gel-infused foam pad | Memory foam with a gel layer or gel beads | Warm sitters who still want cushioning | Heavier; gel’s cooling effect fades within the first hour of a session | Spot clean | $20–35 |
On foam quality: look for memory foam around 3 lb/ft³ density or better. Pads under ~2 lb/ft³ bottom out quickly — within weeks your elbow compresses straight through to the hard armrest underneath and the pad becomes a sleeve that cost more.
Installation: Slip-On vs. Strap-On vs. Screw-On
Slip-on sleeves (elastic or zippered)
- Elastic sleeves stretch over the pad like a sock — a two-minute job if your circumference is inside the rated range.
- Zippered sleeves wrap around and close, which handles tapered armrests and odd shapes (like pads with a lever bump underneath) far better.
- Prefer molded plastic zippers — exposed metal teeth can scratch the chair’s frame or base when the armrest swings low.
- Fit test: press your palm flat on the cover and twist. If the sleeve rotates with your hand, it’s too loose and will migrate within days.
Strap-on foam pads
- Two velcro or elastic straps wrap under the armrest — the closest thing to a universal fit, even on sculpted or extra-wide pads.
- Position straps near the front and rear ends of the pad, clear of the height-release button and any pivot points; a strap parked on top of the release lever is the number-one annoyance with these.
- Snug, don’t crank — over-tightening compresses the foam unevenly and creates a ridge under your forearm.
- Recheck elbow geometry after install: you want elbows near 90–100° with relaxed shoulders. If a 1.5 in pad shrugs your shoulders up, it’s fixing your elbow and taxing your neck.
Screw-on replacement pads
- These replace the armrest top entirely. Remove the two to four screws underneath, lift the old pad, bolt the new one on.
- Hole spacing is not standardized — measure center-to-center before ordering and compare against the pad’s slotted range (universal pads typically accommodate roughly 4–7 in).
- If your armrest tops are riveted or glued with no visible screws, this route is off the table — use a cover instead.
- A few flagship chairs use proprietary quick-swap tops — for example, Secretlab’s Titan Evo armrests release magnetically. On those, buy the maker’s own replacement tops rather than fighting a generic cover over the mounting hardware.
Match the Cover to Your Situation
| Your situation | Best pick | Why |
|---|---|---|
| Stock armrest is peeling or cracked | Zippered PU or fabric sleeve | Hides the flaking and contains the mess — brush off loose flakes before covering |
| Elbow or ulnar-nerve ache during long sessions | 1–1.5 in memory foam strap-on, ~3 lb/ft³ | Spreads point pressure across the whole forearm |
| Hot climate or sweaty palms | Thin stretch fabric sleeve | Breathes; PU and foam both run warm |
| Cats that knead the armrests | Two cheap fabric sleeves | Sacrificial, washable, and replaceable |
| Armrests already near desk height at max | 1–3 mm fabric sleeve only | Foam adds an inch-plus you don’t have |
| Magnetic or proprietary armrest system | Manufacturer’s own tops | Generic covers won’t sit flat over quick-release hardware |
What Wears Out First (and How to Slow It Down)
- Elastic hems relax after roughly a year of on-off washing — air-dry rather than tumble to stretch that out.
- Velcro straps clog with lint and lose grip; pick them clean monthly.
- PU sleeves peel on the same timeline as the armrests under them — expect 6–18 months and treat them as consumables.
- Foam pads develop an elbow dent. Rotate the pad 180° every few weeks to spread the compression.
- Wash sleeves monthly regardless of type. Sweat and skin oil are what killed the PU underneath in the first place — a dirty cover recreates the same chemistry on the new surface.
FAQ
Do armrest covers work on 4D adjustable armrests? Yes — adjustability doesn’t affect fit since covers only touch the top pad. Just keep strap-on pads clear of the buttons and pivot points.
Will a cover stop my armrest from peeling further? It hides the damage and dramatically slows flaking by removing friction and sweat contact, but scrape off loose flakes first or they’ll grind into the cover’s lining.
Do these covers fit regular office chairs? The sizing overlaps almost completely — measure circumference the same way. Office chair armrests are often slightly narrower, which just puts you at the low end of the same ranges.
Can I machine-wash a memory foam pad? The cover, yes. The foam, no — water-logged memory foam crumbles. Spot-clean it and let it air out.
