Doublelife King Size 5FT 11 Inch Gel Memory Foam 9-Zone Pocket Spring Mattress (150x200x28cm)

What this mattress is for

If you and your partner tend to notice each other’s movement during the night, this Doublelife king size mattress is built around the idea of independent support. It combines gel memory foam with an individually pocket-sprung core, plus a breathable cover designed to help with airflow and temperature comfort.

On paper, it’s aiming for a “medium firm” feel: enough structure to support your back and hips, with comfort foam to take the edge off pressure. The 9-zone approach also suggests you’ll get firmer support in heavier areas (like hips and shoulders) and softer feel where you need it to relax.

The support feel: gel foam + 9-zone pocket springs

The headline here is the mix of gel memory foam and a 9-zone pocket spring system. The memory foam layer is there for contouring comfort, while the separately working pocket springs are meant to reduce pressure points and keep your body aligned.

The 9-zone design is the bit that matters if you want more than a one-size-fits-all mattress. Instead of simply being responsive everywhere, it’s designed to vary support by body area. Whether that translates into a noticeably “smarter” feel depends quite a lot on your body weight, sleep position and how you like your mattress to cradle versus push back.

Motion isolation that actually targets partner movement

For many couples, “motion isolation” is the difference between getting a proper night’s sleep and constantly adjusting. With individually pocket springs working independently, this mattress is designed so movement on one side is absorbed and doesn’t travel across as much.

If one of you tosses and turns, or you frequently get up during the night, that’s where this mattress is meant to pay off. It’s not magic (physics still applies), but the construction is clearly chosen for sleep disturbance reduction rather than just bounce.

Breathability and temperature comfort (what to expect)

The cover uses a breathable 3D fabric described as promoting airflow through the mattress layers, helping regulate temperature and wick away moisture and heat. In real life, this can be a practical advantage if you run warm at night, or if your bedroom doesn’t stay cool.

That said, “cool all night long” is always a bit of marketing language. It can help, but your room temperature, bedding choices and your own heat retention still play a big role. Think of it as supportive comfort, not a guarantee.

Where it fits your sleep needs (and where it may not)

It’s worth considering if you want: - Medium firm support with comfort foam on top - A king size mattress with motion isolation to reduce partner disturbance - A breathable cover aimed at temperature and moisture comfort - A mattress that blends zoning (9-zone pocket springs) with contouring memory foam

It may not suit you if you strongly prefer a very plush, soft mattress that feels like a deep hug, or if you dislike memory foam’s more “moulding” sensation. Also, the mattress’s height and construction will matter for topper choice, bed frame fit, and how it feels on your current set-up—something to double-check before you commit.

Tech details at a glance

This model is described as a king size mattress with gel memory foam and an individually pocket spring system, featuring 9-zone support and edge support. Dimensions are given as 150x200x28cm, with a stated depth of 5FT 11 Inch in the product name.

One detail worth noting is “edge support”. If you tend to sit on the edge of the bed, or you share the mattress with frequent edge use, this feature is designed to help reduce the feeling of sagging there—again, your exact experience will depend on your weight and sleep posture.

Buying verdict

Is it worth it?

Buy it if you’re shopping for a king size mattress that prioritises medium firm support, partner movement reduction (via individually pocket springs) and temperature comfort (via breathable 3D fabric). The gel memory foam and 9-zone idea make it more targeted than basic foam-only or simpler spring mattresses, so it can make sense if you want comfort plus structure.

Skip it if you know you prefer a very soft or very springy feel, or if you specifically dislike memory foam contouring. You may also want to be cautious if you’re expecting a “perfect for everyone” solution—zoned support and comfort feel are heavily personal.

Finally, take advantage of the reassurance of a 100-night trial mentioned with the product. A mattress is one of those purchases where the real test is your sleep at home, not just how it sounds on the listing.

The individually pocket springs are intended to reduce motion travel, so it’s a sensible pick if partner movement disrupts your sleep.

Will it help with sleeping hot?

The breathable 3D fabric cover is designed to promote airflow and wick away moisture and heat, which may help if you tend to run warm.
