Quick answer: all three ERGONOZ arm families are full-motion gas-spring arms with 75×75/100×100 VESA, clamp-or-grommet mounting, and built-in cable management. The CORE (฿1,290) is the default choice — best balance of build and price with a 2-year warranty. The PYROZ (฿1,390) is the EZZENTIAL essentials line. The ASTRO (฿2,990) is the premium pick: bigger screens (up to 35"), heavier loads (up to 12 kg), plus two USB 3.0 ports at the base.
The lineup in one minute
- CORE (Single ฿1,290 / Twin ฿2,200) — the best-seller. Aluminum-and-steel build, powder coat, 2-year warranty. If you have a normal 17–32" monitor, this is the one.
- PYROZ (Single ฿1,390 / Twin ฿2,290) — the EZZENTIAL line: same screen range and motion, matte-black finish, 1-year warranty. Pick it when its look or a deal wins you over.
- ASTRO (Single ฿2,990) — the premium arm: 13–35" screens, 2.5–12 kg capacity, elastic-coating finish, and a 2-port USB 3.0 hub built into the base so your webcam or drive plugs in at desk level.

Pick by your monitor
Standard 24–27" office or gaming monitor
Any arm here holds it easily. The CORE Single wins on warranty per baht; step up to ASTRO only if you want the USB hub.
Dual monitors
The CORE Twin (฿2,200) and PYROZ Twin (฿2,290) both hold two 17–32" screens at 2–9 kg each. At near-identical prices the CORE's 2-year warranty is the tiebreaker — unless the PYROZ matte look fits your setup better.
Ultrawide, 34–35", or heavy monitors
This is ASTRO territory: the 13–35" / 2.5–12 kg envelope covers ultrawides and heavier pro monitors that exceed the 32" / 9 kg limit of the other arms. Under-loading matters too — a very light 13" portable display sits happier on ASTRO's wider range than on an arm sprung for 2 kg minimum.
Frequently asked questions
What is actually different between CORE and PYROZ?
Motion specs are the same. The differences: CORE has an aluminum-forward build with a 2-year warranty; PYROZ is the EZZENTIAL line with a matte finish and 1-year warranty. Most buyers pick CORE for the warranty.
Is the ASTRO worth ฿2,990?
If your monitor is over 32" or over 9 kg — it is the only correct choice here. Otherwise you are paying for the wider range, the USB 3.0 hub at the base, and the elastic-coat finish. Genuinely useful; not mandatory.
Can I put a 34" ultrawide on a CORE arm?
No — 34" exceeds the CORE's rated 17–32" range even when the weight fits. Use the ASTRO, which is rated to 35" and 12 kg.
Can a twin arm hold two different-sized monitors?
Yes, as long as each screen is within 17–32" and 2–9 kg. Each arm adjusts independently, so mixed sizes and heights align without spacers.
Is installation the same across all models?
Yes — every model includes both a desk clamp and a grommet mount, tool-in-box installation in about 15 minutes, with cable channels along the arm. For thin or fragile desktops add the reinforcement plate.
The bottom line
Normal monitor → CORE. Tight budget or matte look → PYROZ. Big, heavy, or USB-hungry setup → ASTRO. See them all side by side in the Monitor Arms collection — free shipping over ฿800, Thai warranty on every arm.
