eXtreme Comfort Flame Essentials Hybrid Review UK 2026

Key specifications

Comfort and Firmness

Despite the exact feel varying by person, the eXtreme Comfort Flame Essentials Kingsize mattress is specified as a plush comfort support hybrid, using an 18cm deep Bonnell open coil spring base. Comfort depends on body weight and sleeping position, with lighter users typically feeling the top layers more, while heavier users may notice firmer coil response. The "foam free" build indicates it avoids a traditional foam feel, which some people prefer for bounce. The Cooltouch cover is designed to offer cooling, which can improve perceived comfort, but it does not change firmness.

Support and Spinal Alignment

Support and spinal alignment are shaped by an 18cm deep Bonnell open coil spring base, designed to provide a responsive, structured feel beneath the body, while a plush comfort support layer is intended to cushion pressure points on top. In use, this hybrid construction adapts to different sleeping positions as the coils respond to body weight and the upper layer helps soften pressure around the shoulders and hips. Many sleepers may find the overall feel stable, though those who prefer more pronounced spinal contouring may find the plush top slightly less direct. If alignment feels uneven, adjusting sleeping position and testing the mattress over several nights can help confirm whether the balance of support and cushioning suits.

Materials and Construction

This mattress Kingsize mattress is a hybrid design, combining an 18cm deep Bonnell open coil spring layer with a foam-free plush comfort support layer on top. The coil base forms the main resilient structure, while the plush comfort layer provides a softer feel without adding foam. A breathable Cooltouch cover helps protect the inner materials from everyday wear. As with many hybrid builds, edge support can vary depending on where a sleeper sits, and the overall firmness feel depends on body weight distribution. Construction is straightforward, with responsiveness largely tied to how the Bonnell coils behave.

Temperature and Breathability

Temperature and breathability are important because mattresses that retain more warmth can feel less comfortable during sleep. The eXtreme Comfort includes an 18cm deep Bonnell open coil spring layer, a cooling gel layer, and a breathable Cooltouch cover designed to support airflow through the fabric. With this combination, the mattress is aimed at sleepers who tend to sleep hot, as the cooling layer and airflow-focused cover work together to manage heat. The mattress is also plush and soft, so very warm sleepers may still find it less effective if their bedroom stays hot.

Motion Isolation and Edge Support

Because a hybrid mattress combines a spring core with comfort layers, it can influence both how movement is absorbed and how well the sleeping surface holds up near the sides. With a Bonnell open coil spring base (18cm deep, foam-free), motion transmission is typically greater than in all-foam designs, although the plush comfort support layer may soften light shifting. For shared sleeping, that means rolling across the bed can be noticeable at the other end, particularly during quick turns. Edge support is affected by the spring framing, so sitting near the perimeter should feel steadier than a flexible top alone, though it may still dip under body weight.

Size and Depth Options

With a hybrid build that mixes an 18cm deep Bonnell open coil spring layer and plush comfort support, the way the bed feels near the edges can also depend on overall size. More surface space can spread out pressure and reduce how often someone ends up right at the perimeter. This mattress is available in a Kingsize option, measuring 150 x 200cm, which offers wider side-to-side room for couples or restless sleepers. Larger layouts also give partners more space to shift position without feeling each other's movement. Depth is fixed at 18cm from the open coil layer, so changes are mainly about width and length rather than thickness.

Durability and Warranty

Durability on the eXtreme Comfort Flame Essentials Kingsize Mattress is primarily linked to its 18cm deep Bonnell open coil spring layer. Coils typically handle repeated movement better than an all-foam build, while edge support and comfort can vary depending on how much load is placed near the perimeter. The mattress is described as foam free, so any visible wear patterns are likely to be concentrated around the cover and spring support rather than foam breakdown. Warranty terms are not stated in the provided product details, so buyers should check the official UK documentation for the coverage length and exclusions.

Who Is This Mattress For?

The eXtreme Comfort mattress (150 x 200cm, 18cm deep Bonnell open coil spring) is best suited to people who want a traditional spring feel rather than an all-foam bed. It is aimed at those who prefer plush comfort support and who like a breathable Cooltouch cover for sleeping. Because the build is foam free, it is suitable for shoppers who dislike foam layers. Couples sharing the 150 x 200cm sleeping surface should test for individual comfort.
