FirmNest Plus King Single Mattress
About this mattress
Measuring 107cm x 203cm, the LivingTopia FirmNest Plus King Single Mattress matches a New Zealand standard king single base. Above the springs: a 3cm high-density foam pad under an anti-pill knitted cover, kept simple on purpose. The springs themselves are 20cm of pocket springs wound from 1.8mm wire, with a 1.9mm reinforcing rail on all four sides, and together they read Medium Firm, 4 out of 10 where 10 is softest. On the outside is anti-pill knitted fabric holding OEKO-TEX® STANDARD 100 certification, and the foam layers are CertiPUR-US® certified. At 23cm thick with a tight top, it weighs 22.0kg. It arrives roll-packed in a 28cm x 28cm x 117cm carton, which matters when a 203cm length has to get round the turn of a staircase, and once unrolled it is typically at full height within 72 hours.
Who this mattress suits
- A single sleeper who wants more than 92 cm of width without moving up to a 137 cm double, at 4 out of 10.
- Sleepouts and granny flats where a queen will not fit but a single feels mean, and a Medium Firm surface is what is wanted.
- Guest rooms that host adults rather than children, where the reinforced perimeter is worth paying for.
Why choose the FirmNest Plus
The spring unit is the part that decides how this mattress holds you: a 20 cm pocket spring unit in 1.8 mm wire, ringed by three rows of thicker 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 4 out of 10.
Between you and the springs: a single comfort layer of 3 cm high-density foam, under a knit chosen because it does not bobble as quickly as a plain one. A king single is narrow and long, so the comfort layers matter most down the middle line of the 23 cm build.
The four FirmNest tiers get firmer as they go up — Classic 5 out of 10, Plus 4, Pro 3 and Prime 2, where 10 is softest. Against the Classic king single, the Plus is firmer by a point, 23 cm instead of 19 cm, and edged in 1.9 mm wire; against the Pro king single it lacks zoning and the gel layer. A king single is usually one person's decision too, and at 4 out of 10 the 203 cm length is the other half of the choice.
Movement carries less than it does on an open-coil bed, since the springs are individually pocketed. Buy standard New Zealand king single sheets — a 203 cm length and a 23 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 weight | 22.0 kg |

Check the sheet depth before delivery. At 23 cm this stays inside the range a standard king single fitted sheet is cut for. Roll-packing puts it into 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, and once opened it is typically at full height within 72 hours.

Frequently asked questions
How firm is the FirmNest Plus King Single?
Medium Firm, 4 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 Plus compare with the Classic and the Pro?
The Plus is 4 out of 10. The Classic below it is 5 out of 10 and so slightly softer, 19 cm rather than 23 cm tall, and has no reinforced perimeter. The Pro above it is 3 out of 10, 26 cm tall, and adds three-zone springs and a 1 cm gel memory foam layer. All numbers are on a scale where 10 is softest. For a king single the firmness step is usually the deciding factor rather than the size.
What does the reinforced edge do?
Three extra rows of thicker 1.9 mm wire run right around the perimeter of the 20 cm spring unit. The edge keeps more of its shape when you sit on it to put shoes on, and more of the width stays usable for sleeping. Along 203 cm of king single, the reinforcing runs the whole side.
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?
Standard-depth king single sheets are the right buy for a 23 cm mattress. King single sheets are sold in most bedding aisles, but check both the 203 cm length and the 23 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.
