The Calais Open Coil Mattress is a classic, UK-made mattress designed for sleepers who want reliable, no-nonsense comfort with a touch of understated style. Built around a traditional open coil spring system, it offers steady, responsive support and breathable comfort to help you drift off easily and stay comfortable through the night.

A robust open coil unit sits at the heart of Calais, engineered to distribute weight evenly across the mattress and support the body in a range of sleeping positions. The spring layout also encourages airflow, helping to keep things cooler and extend the life of the mattress. Comfort layers on top work with the springs to soften pressure points around the shoulders, hips and back, so the mattress feels supportive without being harsh.

Calais is available in all the most popular UK sizes – Single, Small Double, Double, King and Super King – making it easy to pair with standard divan bases and bed frames in almost any bedroom, from compact rooms to larger master spaces.

Built with durable components and careful construction, the Calais Open Coil Mattress is designed to hold its shape and support over years of regular use. Rotate it regularly and place it on a level, well-ventilated base to help maintain performance and comfort over time.

If you’re looking for a straightforward, supportive mattress that feels comfortable, breathable and easy to live with, Calais is a dependable choice that fits seamlessly into modern and traditional bedrooms alike.
