If your staircase has a turn, an intermediate landing, or pie-shaped stairs, you need a curved stairlift (also called a curved stair lift or custom chair lift). The travel rail is fabricated to follow your staircase, not cut from a straight length.
In 2026, a curved stairlift generally starts at $10,000 USD, including installation. Most projects fall between $10,000 and $20,000.
A straight stairlift costs less because the rail is standardized. A curved rail is made for one home, which is why the price is higher — and why an accurate survey matters before you order.
