Choose the staircase that lasts. The Craftsmans Pine bottom winder (L/H) upgrades key components to solid timber treads and plywood risers, delivering a sturdier feel underfoot and a far longer service life than entry-level MDF designs. Ideal where you need a compact turn at the bottom of the flight—without compromising quality.
