The answer — one pick, priced
Get the
Razer Iskur V2 X
right at your $250 cap
The only chair under $300 with the lumbar arch moulded into the backrest instead of a pillow that slides — and at $249.99 it undercuts Razer's own list by $50.
Fit ledger — need → measured evidence
■ The catch — co-equal billing, always
The arch is fixed and the armrests are only 2D. You get Razer's curve, not your own — no knob, no depth or height adjustment on the lumbar, and arms that move up and down and rotate but never forward. That is not a flaw in this chair, it is the ceiling of the price tier: genuinely adjustable integrated lumbar does not exist below ~$549. And no chair treats back pain — OSHA's seat-height and backrest-contact guidance applies whatever you buy.
Dealbreaker? The Secretlab Titan Evo's **4-way adjustable lumbar** is the actual fix, at **$669** — 2.7x the money. ↓

Traps — this verdict avoids
Why the Razer Iskur V2 X is right for you
It avoids every trap below — and for just me, under $250, it is the pick because it delivers:
A pillow is not lumbar support
Most listings under $200 call a strap-on cushion "lumbar support". It slides down your back and needs resetting every hour of a long session. Under $300 the real thing is a fixed arch moulded into the backrest (Razer Iskur V2 X); lumbar you can actually *adjust* — Secretlab's 4-way, Razer's HyperFlex 360° — does not start until $549–$650.
PU leather peels in 1–3 years
Flaking synthetic leather is the single most common durability complaint in this category, and hot or humid rooms accelerate it. Fabric lasts far longer and breathes — and it is now the cheaper option: the fabric Razer Iskur V2 X is $50 less than the identical chair in EPU leather.
400 lb is a static number
Capacity is rated under static load on a flat floor — rocking, leaning and dropping into the seat cut effective support by 15–25%, so a 300 lb rating is really ~225–255 lb in use. Height range is a separate spec nobody reads: the Anda Seat MANA is rated 300 lb but sized 5'1"–5'11", and no chair here goes past 400 lb.
