Description

The softest, most cloud-like comfort King Koil offers—cool, plush, and beautifully supportive.

The Newbury Ultra Plush is the top of the King Koil collection, designed for sleepers who want the deepest, most cushioned feel possible. Its ultra-plush surface gently hugs the body, easing pressure around the shoulders and hips while maintaining steady support underneath. Multiple layers of plush foams, natural fibers, breathable latex, and adaptive micro coils create a cool, airy sleep surface that moves with you and feels luxuriously soft from the moment you lie down. If you love the sensation of sinking into softness while still staying aligned and supported, this is the most indulgent, body-hugging comfort King Koil makes.

Best for side and combination sleepers who want maximum plushness with cooling airflow and dependable support.
