Cooling Plus 3 Zone Pocket Spring Mattress - Super King
About this mattress
The Cooling Plus 3 Zone Pocket Spring Mattress in Super King is a 183cm x 203cm super king pocket spring mattress built to standard New Zealand dimensions. Support comes from an 18cm independent pocket spring unit divided into three zones, under 3cm of high-density foam and a 2cm comfort layer that together set the feel at Firm, 3 out of 10 where 10 is softest. The cover is an ice silk fabric that feels cool against the skin, OEKO-TEX® STANDARD 100 certified, and the foams inside are CertiPUR-US® certified. The mattress is 23cm thick with a tight top and weighs 37.8kg. It ships roll-packed in a 28cm x 28cm x 193cm box, so a 183cm wide mattress reaches an upstairs bedroom without being folded, and it is typically at full height within 72 hours of unrolling.
Who this mattress suits
- Two adults across 183 cm who want a firm surface rather than a cushioned one.
- Low bed frames, where a 23 cm mattress keeps the finished sleeping height where you want it.
- Households moving off an undivided spring bed and wanting the support broken into zones.
Why choose the Cooling Plus
The Cooling Plus Super King is built firm. Under the ice silk cover sit 3 cm of high-density foam and a 2 cm comfort layer, and beneath those an 18 cm pocket spring unit divided into three zones, for 23 cm in total. The top is a tight top, so the surface stays flat and level rather than cushioned, and the feel comes out at Firm, 3 out of 10 where 10 is softest.
Against the Cooling Classic this is the firmer and thicker of the two. The Plus runs 23 cm to the Classic's 18 cm, three zones against a single undivided spring field, and 3 out of 10 against the Classic's 4. If the Classic felt too giving across a 183 cm width, the Plus is the direct step up without changing the size of the bed.
The cover is an ice silk fabric. It is smooth and densely woven, and it takes heat off the skin faster than a brushed knit, which is why the surface feels cool the moment you lie on it. The effect is confined to the surface; it is not air conditioning and it will not lower the temperature of the room. OEKO-TEX® STANDARD 100 certification applies to the cover and CertiPUR-US® to the foams. Certificate numbers are available from our team on request.
The mattress weighs 37.8 kg and has no side handles, so plan on two people to position it on the base. Three zones across a 183 cm width means the springs under the middle of the bed respond differently from those under the head and the legs, and because each spring sits in its own pocket, less of one sleeper's movement carries to the other side.

Firmness is felt, not measured. Body shape, weight and sleeping position all change how the same surface reads, so use this level to compare our mattresses with each other rather than as a promise of how it will feel to you.

Frequently asked questions
How firm is this mattress?
Firm, 3 out of 10 where 10 is softest. The tight top keeps the surface flat and there are only 5 cm of foam over an 18 cm spring unit, so the springs set the feel rather than the padding. Firmness is felt rather than measured, so use that rating to compare our mattresses with each other rather than as a promise of how it will read to you.
How does the Cooling Plus compare with the Cooling Classic?
The Plus is firmer and thicker. It is 23 cm deep against 18 cm for the Classic, its spring unit is divided into three zones where the Classic uses a single undivided field of springs, and it rates 3 out of 10 where the Classic rates 4, with 10 being softest. Same footprint, more height and more division of support.
What does the ice silk cover actually do?
It changes the first contact. Ice silk is a smooth, densely woven fibre that carries heat off the skin faster than a brushed knit does, so the surface feels cool as you lie down on it. It is a surface effect and not air conditioning: it will not lower the temperature of the bedroom, and the fabric warms once you have settled in one place.
What certification does this mattress have?
The cover is certified to OEKO-TEX® STANDARD 100 and the foams inside are certified to CertiPUR-US®, so both the fabric against your skin and the foam under it are covered. Certificate numbers are available from our team on request.
What sheets do I need for this mattress?
Standard New Zealand super king fitted sheets. At 23 cm the mattress sits inside the depth most sheets are cut for. If your set is an older or shallower cut, check the wall measurement on the packet against 23 cm before you put it on.
Will I feel my partner moving on the other side?
Less than you would on an undivided spring bed. Each spring is enclosed in its own pocket and the unit is split into three zones, so a spring compresses under the weight on it instead of pulling its neighbours down, and 183 cm of width puts distance between you. Some movement still carries. The mattress is one-sided and has no side handles, so plan on two people to rotate it head to foot every few months.
