WHY THE PRICE IS JUSTIFIED

The cost is visible in the Harmonic 2 mechanism, high-cycle suspension materials, aluminum structure, genuinely broad arm/seat controls and a 12-year 24/7 warranty. BTOD measured excellent assembly quality and 200,000-double-rub mesh. Specify adjustable lumbar and Butterfly back: those functional upgrades justify money better than cosmetic finishes.
