King Koil Whitby Euro Top Mattress

Description

Breathable comfort and balanced support—designed for steady, all-night alignment.

The Whitby Medium Euro Top offers a balanced mix of cushioning comfort and steady support—ideal if you want pressure relief without losing alignment. A breathable silk–wool quilt provides instant softness and temperature balance, while cooling graphite-infused latex helps reduce heat and ease tension. Adaptive micro coils enhance responsiveness and motion isolation, and the supportive coil system keeps your spine aligned from edge to edge. What sets the Whitby apart is its blend of natural fibers, cooling latex, and micro-coil responsiveness—creating a feel that’s truly balanced, not too firm or too plush.

Best for sleepers who love a medium, contouring feel with dependable support.
