Bedroom by Coolflex�

You know that feeling when you climb into a hot bedroom on a summer night and the sheets just hold the heat in. Coolflex built a mattress range to fix exactly that.

Coolflex is a UK-stocked sleep brand designed around one idea: a mattress should manage your body temperature, not fight it. Every range layers pocket springs with foam tuned for airflow, and the lineup spans soft to firm so you pick the support level you actually need rather than settling for whatever the brochure suggests.

The five Coolflex ranges, by sleep style

The line-up reads like a temperature scale.

Coolflex Essentials Pocket is the entry point. 800 pocket springs paired with a memory-foam comfort layer, sized for a spare room or a first home where you want a step up from a budget mattress without paying for the heavy cooling tech.

Coolflex Premium Memory lifts the foam thickness for side sleepers who want a softer sink at the shoulder and hip. Same pocket-spring core, deeper comfort layer.

Coolflex Lux Ortho swaps comfort for firmer support. A denser pocket-spring core sits under a thinner memory-foam top, so heavier sleepers and back sleepers get the lift they need without the mattress collapsing under load.

Coolflex Hybrid Chill is where the cooling story starts. Gel-infused memory foam on top draws heat away from your pressure points, the same idea you find in some sports bedding.

Coolflex Hybrid Ice goes a step further with a phase-change cover, the technology used in high-performance running shirts. The cover absorbs heat as you warm up, holds it, then releases it back into the room as you cool down.

There's also a Coolflex Cool Gel mattress topper for sleepers who want some of the cooling benefit without replacing a working mattress. Sits on top of your existing bed, adds a layer of gel-infused memory foam.

Sizes, options, what to expect

Sizes run Single, Small Double, Double and King across all the mattress ranges. Most are sold either as a mattress on its own or paired with a Coolflex divan base in a choice of fabric finishes (Mink, Cream, Carbon, Silver, Marine and Teal). Headboards and ottoman storage options sit on top of the divan models.

Coolflex reviews

Coolflex have a Trustpilot presence that's worth a quick look before you buy. The pattern in customer feedback tends to mirror what you'd expect from the range structure. Buyers of the cooling lines (Hybrid Chill, Hybrid Ice) consistently mention the temperature difference vs their previous mattress as the headline gain. Buyers of the Lux Ortho mention back support. Essentials Pocket reviews skew toward value-for-money rather than premium-feel, which is what the price point promises.

Read the customer reviews on Trustpilot and the merchant's own product pages before you commit. Mattresses are a high-trial product and the right one for you depends on body weight, sleep position, room temperature, and what you're sleeping on now.

If you sleep hot, share a bed with a partner whose body temperature runs higher than yours, or live in a south-facing room that holds the day's warmth past bedtime, the Hybrid Chill or Hybrid Ice ranges are where to start. If support and value matter more than cooling, the Essentials Pocket or Lux Ortho lines do the basics well at a lower price.
