eXtreme Comfort Flame Essentials Review UK 2026

Key specifications

Comfort and Firmness

Comfort on this mattress is shaped mainly by its hybrid build, with an 18cm-deep structure that combines a Bonnell open coil spring core and a foam-free approach. This combination is designed to deliver plush comfort rather than a rigid feel, with the coil support helping create bounce while the surface stays comfortable. The firmness tends towards a softer, more flexible feel, which is likely to suit side sleepers and people who change positions during the night. Those who prefer a very firm mattress with minimal give may find it less stable. The breathable Cooltouch cover is intended to help reduce heat build-up, but comfort remains subjective.

Support and Spinal Alignment

Support from the eXtreme Comfort is driven by its hybrid construction, with an 18cm-deep Bonnell open coil spring layer acting as the main support. This deeper spring base can help keep the sleeping surface responsive, supporting a more neutral posture by distributing pressure across the body. For side sleepers, spinal alignment is influenced by how well the plush top cushioning cradles the hips, as misalignment often starts there. Heavier areas may sink more, so rotation can help reduce uneven wear patterns. Edge support is not stated, so the perimeter may feel less stable.

Materials and Construction

Materials and construction for the eXtreme Comfort Flame Essentials Double mattress use a hybrid design. The base is an 18cm-deep Bonnell open coil spring system, paired with a foam-free plush comfort layer and a soft cooling gel layer. The mattress has a breathable Cooltouch cover, designed to help keep the outer fabric comfortable during everyday use. The coil core provides structured support, while the foam-free top is intended to deliver a softer surface feel rather than an overly cushioned one. Because the gel layer and comfort feel depend on body pressure distribution, some sleepers may notice firmer zones. The mattress is UK made, with dimensions 135 x 190cm.

Temperature and Breathability

Temperature and breathability are key focus areas for the eXtreme Comfort mattress, featuring a cooling gel layer and a breathable Cooltouch cover. The gel layer is designed to help manage sleeping heat, while the cover supports airflow to reduce the feeling of trapped warmth. In everyday use, this combination is positioned as a better fit for people who tend to sleep hot across longer nights. Temperature control can still vary with room conditions, bedding choices and individual body heat, so the cooling comfort should be noticeable rather than constant, climate-controlled.

Motion Isolation and Edge Support

Beyond staying comfortable through the night, the eXtreme Comfort Flame Essentials Double mattress also aims to address movement across the bed and stability near the edges. As a hybrid with an 18cm deep Bonnell open coil spring core, it uses an open coil construction, which distributes body weight through the spring unit rather than concentrating all load in one area. Edge support depends on perimeter reinforcement, and that detail is not stated, so sink into the edge is possible, especially for heavier sleepers.

Size and Depth Options

The eXtreme Comfort Flame Essentials Double is offered as a Double mattress, measuring 135 x 190cm. This single size suits couples who want a wider sleep surface than a smaller bed, but it may feel tight for larger frames or frequent turning. The mattress depth is listed as 18cm, which indicates a medium-thickness build that sits visibly higher than thinner options, though it is not extremely tall. In use, shoppers should check their bed frame height and sheet fit, since the stated depth affects the overall mattress profile and how sheets mount. Overall, these dimensions are clear, while other sizes are not stated.

Durability and Warranty

Durability and Warranty are often what shoppers check after confirming the mattress size and how its 18cm depth will sit in their bed frame. The Flame Essentials Double is built as a hybrid using a Bonnell open coil spring core with a breathable cooltouch cover, plus a plush support feel. Durability depends on how often it is rotated and how it handles body weight over time.

Who Is This Mattress For?

This mattress suits shoppers looking for a medium feel in a Double (135 x 190cm) size, with an 18cm depth designed to fit standard bed frames more easily than very thick models. It is intended for people who want a plush, supportive sleep surface without a foam build, as the title specifies a bonnell open coil spring and foam free design. The breathable cooltouch cover may appeal to sleepers who run warm and need improved airflow through the night. The Flame Essentials is a practical choice for couples wanting shared comfort, though its softer bias may not suit firmer-preference sleepers.
