Assessed from Coolflex's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.
This is a sensible pick if you want a hybrid without a big spend. The 800 pocket springs move independently, which means you feel support where your body needs it rather than a uniform push-back, and the memory foam layer softens pressure at your hips and shoulders. It carries hypoallergenic and antimicrobial certifications, useful if allergies bother you at night, and it's vegan friendly. Yes, the 2cm memory foam layer is thin compared with deeper-topped hybrids, but at this price the balance of springs and foam is hard to fault. Five sizes are available, from UK Single up to UK Super King, and free next day delivery means no long wait.
Key Features & what's inside
- Memory Foam. A 2cm layer of memory foam sits on top, moulding to your body for orthopaedic support and comfort. In practice, this means less pressure on your hips and shoulders as you settle in.
- Pocket Springs. Beneath the foam are 800 individual pocket springs, each hand-sewn into its own fabric pocket. They work independently, so the mattress responds to your shape rather than moving as one unit.

Who's it NOT for?
If you like a very firm feel, or you're a heavier sleeper who needs a thicker comfort layer and a higher spring count, this medium hybrid may feel slightly too soft and simple. Side sleepers wanting deep cushioning might also find the 2cm foam layer a little shallow.

How firm is the Coolflex Essentials Pocket Memory Hybrid mattress?
Coolflex rates it as medium. That middle-ground feel suits most back and combination sleepers, although lightweight side sleepers may want something slightly softer and firm-mattress fans may want more push-back.
How many springs does the Coolflex Essentials hybrid have?
It has 800 individual pocket springs, each sewn into its own fabric pocket so it moves independently. This gives more tailored support than an open-coil mattress, though higher-count hybrids exist if you want extra contouring.
Does the Coolflex Essentials mattress come with a guarantee?
Yes, Coolflex includes a 5-year guarantee. That's a reasonable span for a mattress at this price point, covering you against manufacturing faults for a good stretch of its life.
Is the Coolflex Essentials hybrid mattress good for allergies?
It carries hypoallergenic and antimicrobial certifications, which means the materials are designed to resist common allergy triggers. It's also vegan friendly and meets the BS7177: 2008 low hazard fire resistance standard.
What sizes does the Coolflex Essentials Pocket Memory Hybrid come in?
Five UK sizes: Single, Small Double, Double, King and Super King. Prices range from £179 to £299 depending on the size you choose, with free next day delivery from Coolflex.
