FirmNest Pro King Single Mattress
About this mattress
This king single mattress runs 107cm x 203cm, the New Zealand standard king single footprint, and is listed as the LivingTopia FirmNest Pro King Single Mattress. On top: a soft knitted cover over 3.5cm of profiled wave foam, 1cm of gel memory foam and 1cm of high-density foam, the wave cut giving at the surface without letting the body sink. Underneath: 1.8mm and 1.9mm wire wound into a 20cm spring layer with three zones. Together they read Firm, 3 out of 10 where 10 is softest. It is covered in soft knitted fabric; the cover holds OEKO-TEX® STANDARD 100 and the foams hold CertiPUR-US®. The mattress is 26cm deep, has a tight top, and comes in at 23.5kg. It ships rolled and boxed in a 32cm x 32cm x 117cm carton, which matters when a 203cm length has to get round the turn of a staircase, and given time to open out it is typically at full height within 72 hours.
Who this mattress suits
- Taller sleepers: 203 cm of length is 15 cm more than a single, so feet stay on the mattress rather than over the end.
- Teenagers still growing, where 107 cm of width lasts well past the point a single stops fitting and the gel memory foam layer keeps the surface honest.
- Sleepouts and granny flats where a queen will not fit but a single feels mean, and a Firm surface is what is wanted.
Why choose the FirmNest Pro
Take the foam away and what is left is a three-zone arrangement of 20 cm pocket springs, in 1.8 mm and 1.9 mm wire. A king single is 107 cm wide and 203 cm long, so the springs have to hold a taller frame without letting the hips drop below the shoulders at 3 out of 10.
Above the springs: a three-layer stack — 3.5 cm wave foam, 1 cm gel memory foam, 1 cm high-density foam — beneath a soft knit, with the memory layer spreading pressure where it is loaded. A king single is narrow and long, so the comfort layers matter most down the middle line of the 26 cm build.
It helps to know the ladder before choosing: 5 for Classic, 4 for Plus, 3 for Pro and 2 for Prime, measured with 10 as softest. Compared with the Plus king single the Pro adds zoning, gel memory foam and 3 cm of height; compared with the Prime king single it is one point softer and has a tight top rather than a euro top. A king single is usually one person's decision too, and at 3 out of 10 the 203 cm length is the other half of the choice.
Pocket springs move on their own, so less of your turning reaches the other side of the bed. Buy deep-wall king single sheets — a 203 cm length and a 26 cm depth are both easy to get wrong — and rotate the mattress head to foot every few months.

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.
Size and fit
| Mattress size | King Single |
| Dimensions | 107 cm x 203 cm |
| Thickness | 26 cm |
| Mattress weight | 23.5 kg |
| Shipping box | 32 cm x 32 cm x 117 cm |
| Bedding | Deep-wall king single fitted sheets |
Bedding depth matters at this height. Bedding needs to be deep-wall: 26 cm is deeper than a standard king single fitted sheet allows. On delivery day expect a 32 cm x 32 cm x 117 cm carton rather than a full-size mattress, which solves the awkward part of getting a 203 cm length into an upstairs bedroom, and expect it to be typically at full height within 72 hours.

Frequently asked questions
How firm is the FirmNest Pro King Single?
Firm, 3 out of 10 where 10 is softest. Body weight changes how a king single reads, so treat the number as a comparison point rather than a promise.
How does the FirmNest Pro compare with the Plus and the Prime?
The Pro is 3 out of 10, where 10 is softest. The Plus below it is 4 out of 10, 23 cm tall, and has no zoning or gel memory foam. The Prime above it is 2 out of 10 and 30 cm tall, with seven zones instead of three, a 24 cm spring unit instead of 20 cm, and a euro top. For a king single the firmness step is usually the deciding factor rather than the size.
What does the gel memory foam layer do?
It is a 1 cm layer sitting close to the top. It softens the first few centimetres and spreads pressure where you press into it, so shoulders and hips sit into the surface a little rather than resting on firm foam. It is a comfort layer, not a medical one. It covers the whole 203 cm length of a king single.
What certification does this mattress have?
The cover is certified to OEKO-TEX® STANDARD 100 and the foams are CertiPUR-US® certified. Certificate numbers are available from our team on request.
What sheets do I need for this mattress?
At 26 cm deep this needs deep-wall king single fitted sheets; standard-depth sheets tend to pull off the corners. King single sheets are sold in most bedding aisles, but check both the 203 cm length and the 26 cm depth.
Is a king single really longer than a single?
Yes. A king single is 203 cm long against 188 cm for a single, 15 cm more, and 107 cm wide against 92 cm. That extra length is the main reason people choose it, usually for a tall teenager or adult.
