LivingTopia FirmNest Classic King Single Mattress
About this mattress
Built to the New Zealand king single standard at 107cm x 203cm, this is the LivingTopia FirmNest Classic King Single Mattress. The comfort build is 1cm of high-density foam with 2.5cm of wave foam above it, all behind a Tencel face; below it, the support is a 16cm pocket spring unit wound from 1.8mm wire, giving a feel of Medium Firm, 5 out of 10 where 10 is softest. It is covered in Tencel fabric; the cover holds OEKO-TEX® STANDARD 100 and the foams hold CertiPUR-US®. It stands 19cm tall, is finished as a tight top, and weighs 21.2kg. Delivery is roll-packed, so it ships in a 28cm x 28cm x 117cm carton, which matters when a 203cm length has to get round the turn of a staircase, and after unrolling 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 Tencel cover keeps the surface honest.
- Anyone over about 190 cm tall who has been on a 188 cm base and running out of room on a 19 cm build.
Why choose the FirmNest Classic
Underneath the comfort layers sits 1.8 mm wire wound into 16 cm pocket springs at one tension across the unit. 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 5 out of 10.
On top you get 2.5 cm of wave foam over 1 cm of high-density foam, under a Tencel cover. Tencel is a cellulose fibre that takes up moisture and gives it off again quickly, so the surface stays dry-feeling. A king single is narrow and long, so the comfort layers matter most down the middle line of the 19 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. Nothing in FirmNest is softer than this Classic. The next step up, the Plus, is 23 cm rather than 19 cm and rings the spring unit with thicker 1.9 mm wire. A king single is usually one person's decision too, and at 5 out of 10 the 203 cm length is the other half of the choice.
Individually pocketed springs mean a movement on one side reaches the other side reduced rather than in full. Buy standard New Zealand king single sheets — a 203 cm length and a 19 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

| Thickness | 19 cm |
| Mattress weight | 21.2 kg |
| Shipping box | 28 cm x 28 cm x 117 cm |

Two things to have ready. Standard New Zealand king single fitted sheets fit a 19 cm wall without stretching. It comes roll-packed in a 28 cm x 28 cm x 117 cm carton, which solves the awkward part of getting a 203 cm length into an upstairs bedroom. Give it time to open out, as it is typically at full height within 72 hours.

Frequently asked questions
How firm is the FirmNest Classic King Single?
Medium Firm, 5 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 Classic compare with the Plus?
The Classic is 5 out of 10 and the Plus is 4 out of 10, where 10 is softest, so the Plus is the firmer of the two. The Plus is also 23 cm tall against 19 cm, swaps the Tencel cover for an anti-pill knit, and adds three rows of thicker 1.9 mm wire around the perimeter. Below the Plus there is nothing softer in FirmNest than this Classic. For a king single the firmness step is usually the deciding factor rather than the size.
What does the Tencel cover actually do?
Tencel is a cellulose fibre that takes up moisture and releases it again quickly, so the surface stays dry-feeling rather than clammy. That is a fabric property and nothing more — we make no antibacterial, hypoallergenic, allergy or cooling claims for it. A king single is 203 cm of surface using the same fabric end to end.
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?
19 cm of sidewall means ordinary king single fitted sheets will do, and deep-wall ones will bag. King single sheets are sold in most bedding aisles, but check both the 203 cm length and the 19 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.
