Mattress Buying Guide NZ: How to Choose the Right Mattress.
Buying Guide · Mattresses · NZ Edition Sizes, spring types, firmness, and what actually lasts in a Kiwi home. Plain answers from the TSB Living team, for buying online with confidence. You'll spend a third of the next eight to ten years on this decision. Twenty minutes of reading is a fair trade. If you only read one section Buying a mattress? Get these four right. Most people shop mattresses by price and a vague sense of "firm or soft". These four decisions, in this order, are what you'll actually live with. Use them as your checklist; the chapters below cover the rest, including the NZ-homes advice global reviews never do. Size by the room, then the sleepers. A Queen (153 × 203 cm) needs walking space on both sides. Measure before you fall for a Super King. Type by how you sleep. Side sleepers want a softer comfort layer (foam or Euro top). Back and stomach sleepers want firmer spring support. Couples: springs that move independently. Pocket springs or foam absorb a partner's movement. Connected Bonnell coils pass it straight across. Budget honestly. A kids' or spare bed is solved for under $300. Our most-bought adult Queens sit between $240 and $500. Above that you're buying comfort layers, not necessity. Choosing a mattress comes down to three decisions, in order: the size your room can take, the construction that suits how you sleep, and the firmness your body needs. In New Zealand that means picking from the local size ladder (Single through Super King, including the King Single most countries don't have), then choosing between Bonnell spring, pocket spring, foam, and Euro top builds. For most Kiwi couples, a medium-firm Queen pocket spring or Euro top is the safe answer. For kids and spare rooms, a firmer single under $300 does the job well. Buying online means you can't lie on the bed first, and that worries people more than it should. The specs tell you nearly everything once you know how to read them: coil type tells you about partner disturbance, comfort layers tell you about pressure relief, and firmness ratings only mean something relative to your weight and sleeping position. This guide translates each spec into a plain answer, grounded in what we actually stock and ship across New Zealand. Each chapter starts with its answer in the first line, so skim the bold text and you'll know enough to choose. In this guide Which mattress type is best?

(Bonnell, pocket spring, foam, Euro top.) For most adult beds, a pocket spring or Euro top mattress is the best all-rounder; Bonnell spring is the budget workhorse; foam suits side sleepers and kids' rooms. The names describe what's inside, and what's inside decides how it feels, how it handles two sleepers, and how long it lasts. Every mattress is a support core (springs or dense foam) with comfort layers on top. The four builds below cover nearly everything sold in New Zealand. None of them is "best"; each one is best for somebody. The Four Mattress Builds What's inside each mattress type 🛏️ Bonnell Spring Connected Coils Firm, durable and budget-friendly. The springs are linked together, providing solid support, though movement can travel across the mattress. 🌀 Pocket Spring Independent Coils Each spring moves independently for improved body contouring, targeted support and reduced partner disturbance during the night. ☁️ Foam & Gel Layered Comfort No springs inside. Multiple foam and gel layers provide excellent pressure relief, quieter sleep and cooler comfort. ✨ Euro Top Spring + Plush Layer A supportive spring core combined with a permanently stitched plush top layer for extra cushioning without sacrificing support. 💤 Biggest Mattress Range at TSB Living The support core keeps your spine aligned, while the comfort layers determine how your mattress feels when you lie down. Choose the right support system for your sleeping position, then pick the comfort layer that matches your preferred feel. Bonnell spring: the budget workhorse Bonnell coils are connected in one lattice, which makes them cheap to build, firm underfoot, and very hard to wear out. The trade-off is that the whole surface moves together: roll over and your partner knows about it. For a kids' bed, a flat, a rental, or a spare room, Bonnell is the sensible money. Pocket spring: support that moves one sleeper at a time Each coil sits in its own fabric pocket and compresses independently. The mattress contours to shoulders and hips instead of bridging across them, and movement stays on its own side of the bed. If you share a bed, start here; our X20 range makes pocket springs the budget option too. For a deeper comparison, read our memory foam vs pocket spring guide. Foam and gel: quiet, contouring, great for side sleepers Foam mattresses have no springs to feel through, which makes them silent and forgiving on pressure points. Plain memory foam holds heat; gel-infused layers exist to offset that. Dense foam cores also make excellent firmer kids' mattresses. The thing foam will not give you is that springy push-back some sleepers miss. Euro top: the comfortable middle of the market A Euro top is a spring mattress with a thick cushion layer sewn flush under the cover, so you get spring support with a soft landing. It is the biggest part of our mattress range for a reason: it suits the widest spread of sleepers without committing you to full foam softness or bare spring firmness. Latex: the natural option, when you can find it Latex is springy, breathable, and long-lived, and it tends to cost more per centimetre of comfort. In our range it appears as a 30cm Euro top single. Worth considering for a single sleeper who runs hot and dislikes the memory-foam "sink" feeling. Chapter 02 Our Ranges Which TSB mattress range is right for you? (X20, Euro Top, GEL30, decoded.) Our range names describe the build: X20 is the 20cm pocket spring, PIL20 Euro tops add the sewn cushion layer, GEL30 is a gel-infused memory foam Euro top, and Bonnell is the firm budget spring. Here is the whole catalogue translated into one honest table, so the product pages make sense before you open them.

Two practical notes: some PIL20 listings bundle pillows (the title says so), and the X20, our single most-bought mattress, is a pocket spring at a Bonnell-like price, which is most of why it tops the sales chart.

Prices checked 12 June 2026; current price and stock are always on the product page. Chapter 03 Size What size mattress do I need? (NZ sizes explained.) For couples, Queen (153 × 203 cm) is the NZ default; for a single adult, King Single is the upgrade worth knowing about; for kids moving out of a cot, Single is standard. Sizes below are standard NZ dimensions; always check the listed dimensions on the product page, as they are the ground truth for the mattress you're buying. The NZ Size Ladder Every NZ size, drawn to the same scale Single King Single Double Queen King Super King Single Kids' Rooms 91 × 188 cm The standard first big-kid bed and bunk size. A Long Single (91 × 203 cm) adds 15cm for tall teens. Same scale, honest proportions. Notice the length step: Single and Double stop at 188cm, everything from King Single up runs 203cm. Centimetres are standard NZ sizing; the product page dimensions are final. The room decides before you do. Leave at least 60cm of walking space on each open side of the bed, and remember the mattress has to get there: stairwells and tight hall corners are where Super King ambitions go to die. If you're between sizes for a couple, take the bigger one; nobody has ever complained about too much bed width. One NZ quirk worth knowing: Double and Single share the same 188cm length, while everything from King Single up runs 203cm. Taller than about 180cm? Stay in the 203cm club. Two sizes off the standard ladder that we also stock: Baby Cot mattresses for the nursery stage (check your cot's internal dimensions before ordering, as cot sizing varies more than bed sizing), and California King, a longer, slightly narrower take on King that occasionally appears in our range for very tall sleepers. If a listing shows either, the product page dimensions are the ones to trust. Buy the size the room can breathe around, not the biggest bed that technically fits. TSB Living Team Chapter 04 Firmness How firm should a mattress be? (By sleeping position and weight.) Side sleepers generally do best on medium to medium-soft; back sleepers on medium-firm; stomach sleepers on firm. Body weight shifts the answer: lighter sleepers sink less, so they should aim a step softer, and heavier sleepers a step firmer. "Firmness" has no universal scale, which is why position and weight beat marketing labels. The goal is the same for everyone: a spine that stays in its natural line all night. Whatever your position, the test below is what good support looks like. For a deeper dive by position, read our guide to the best mattress for your sleeping position. The Alignment Test Three quick checks while lying in your normal sleeping position 1 Neck in Line Your head shouldn't tilt up or sag down. If it does, the pillow is wrong before the mattress is. 2 Shoulder Sinks Slightly On your side, the shoulder should settle into the comfort layer rather than prop you up. Pressure here means too firm. 3 Hips Level, Not Hammocked Hips dipping below the line means too soft; hips perched above it means too firm. Level is the win. ✓ A good firmness match keeps your spine in a straight, natural line from your neck to your hips, without creating pressure points. Two sleepers, two answers? Split the difference toward the lighter sleeper's preference (the heavier sleeper compresses any mattress more, effectively softening it for them), or pick a pocket spring or Euro top whose comfort layer does the personalising. Our couples' mattress guide covers the negotiation in detail. Heavier and lighter sleepers: shift the scale Firmness labels assume an average-weight sleeper, roughly 60 to 90kg. Outside that band, adjust deliberately. Lighter sleepers (under about 60kg) barely compress firm comfort layers, so a "medium" can behave like a board for them; aim a step softer than your position suggests. Heavier sleepers (over about 100kg) sink further into everything, so a step firmer restores the support the label promised, and a thicker mattress with a robust spring core will hold its shape for more years. Couples with a big weight difference get the most from pocket springs, where each side responds to its own occupant. Chapter 05 NZ Homes What works in NZ homes: damp, cold, and airflow. In a typical NZ bedroom the mattress needs airflow underneath more than anything else. Cooler, damper rooms slow the overnight moisture every sleeper releases from drying out of the mattress. The fixes are structural and cheap: a slatted base or ventilated foundation, a weekly airing habit, and not parking the bed hard against a cold external wall. This is the chapter global mattress reviews skip, because they assume centrally heated houses. Plenty of NZ bedrooms spend winter cold and a bit damp, and a mattress in that room lives a harder life. Slats or solid base? Slats win on airflow and are the default recommendation for NZ conditions; a solid or padded base gives a slightly firmer, more uniform feel but traps more moisture beneath the mattress. If you go solid, airing matters more. We've written a full comparison in bed base vs slats for NZ bedrooms; the short version is that either works if you manage airflow, and slats forgive laziness better. Under the Mattress Why slats are the NZ default SLATTED AIR MOVES ↑ ↑ ↑ ↑ ↑ Allows natural airflow beneath the mattress. Helps moisture dry more quickly. Popular in many New Zealand homes. ↔ SOLID MOISTURE LINGERS 💧 💧 💧 💧 Provides full, continuous support. Less airflow underneath the mattress. Regular airing helps manage overnight moisture. Every sleeper releases moisture overnight. Gaps between slats allow air to circulate and help the underside of the mattress dry naturally. With a solid base, airflow is more limited, so regularly standing the mattress on its side to air can help keep it fresh. Foam in cold rooms Memory foam firms up in the cold. In an unheated winter bedroom a foam mattress can feel a grade firmer than it did in the warm shop video you watched. It softens again with body heat within minutes; just don't judge it on the first cold-night impression. Mattresses-in-a-box are normal now Most foam and many spring mattresses ship compressed and rolled, which is why a Queen arrives at your door in a box a person can shift. Give it a few hours to take shape and a day or two to lose the new smell in a ventilated room. The full unboxing rundown is in mattress in a box, explained. Editor's Note · NZ Winters The cheapest mattress insurance in New Zealand is a habit: once a week, pull the duvet right back, open the window, and let the bed air for an hour. Moisture is the thing that ages a mattress fastest here, and an hour of airflow undoes a week of it. Chapter 06 Which to Buy Which mattress should you buy? (Best for your situation.) Six situations cover most people reading this. Answer the three questions below for an instant pointer, or scroll the situations and find yours. Fall into two?

Shop Queen mattresses → Situation 03 Best for kids and bunk beds A firmer foam or Bonnell Single, or a Long Single if the height forecast looks tall.

TSB Living Team Chapter 07 Care Making a mattress last (the five-minute habits.) Three habits decide whether a mattress lasts: rotate it, air it, and protect it. None takes more than five minutes, and together they're the difference between a mattress that's done at year five and one still going strong at year ten. Rotate head-to-toe every couple of months for the first year, then seasonally, so body impressions spread evenly instead of digging two permanent hollows. (Modern one-sided mattresses rotate; they don't flip.) Air the bed weekly as covered in chapter 5. And put a washable protector on from day one: sweat and spills age foam and fabric faster than use does, and a protector is the cheapest part of the whole setup to replace. The Ownership Timeline A decade of mattress, five minutes at a time 🛡️ DAY 1 Protector On Start protecting your mattress from spills, dust and everyday wear. 🔄 YEAR 1 Rotate Every 2–3 Months Build a simple rotation routine to encourage even comfort and support. 🌤️ YEARS 2–7 Seasonal Rotate Rotate with the seasons and air the mattress regularly to help keep it fresh. 🔍 YEAR 5 Mid-Life Sag Check Check for body impressions and confirm your mattress is still providing the support you need. 🛏️ YEARS 8–10 Replacement Window Many quality mattresses reach the point where replacement becomes worth considering. The habits are front-loaded. A protector on day one and a regular rotation routine during the first year help set up the quieter middle years. Continue seasonal rotation and airing throughout ownership, and by years 8–10 it's worth assessing whether your mattress still provides the comfort and support you expect. When a mattress does reach the end (visible sag that airing and rotating don't fix, springs you can feel, or waking sore in a bed that used to be fine), replace it rather than nursing it. And when you move house, move it properly: our guide to moving and storing a mattress saves more mattresses than any care tip here. Chapter 08 Complete the Bed What else you need: 6 things people forget. The mattress is half the bed. These six finish the job, and most of them get remembered a fortnight after the mattress arrives. 01 Bed base The right base adds years to a mattress. Slatted bases win on airflow in NZ rooms; whatever you choose, match it to the mattress size exactly. Shop bed bases → 02 Bed frame Gets the mattress off the floor and the airflow underneath it. Check the frame's slat spacing suits your mattress type before buying. Shop bed frames → 03 Pillows The neck's share of spinal alignment. Side sleepers need a higher loft than back sleepers; replace pillows long before you replace the mattress. Shop pillows → 04 Bedding Breathable layers do half the temperature work. Cotton sheets for hot sleepers, layered duvets for cold rooms, and a washable protector under it all. Shop bedding → 05 Complete beds If the frame is as tired as the mattress, replacing both at once gets the sizing guaranteed-matched and usually costs less than two separate decisions. Shop beds → 06 Tallboy Spare bedding needs a dry home; linen stored damp defeats every airing habit. A tallboy keeps the winter layers ready without eating floor space. Shop tallboys → Chapter 09 FAQ Quick answers to the questions customers ask us most. What size mattress should a couple get in NZ? Queen (153 × 203 cm) is the NZ standard for couples and fits most main bedrooms with room to walk. Upgrade to King or Super King only if the room is 3.5 metres wide or more. A Double suits couples only in genuinely small rooms; it's snug for two adults. What's the difference between Bonnell and pocket springs? Bonnell coils are wired together, so the surface moves as one and costs less; pocket springs sit in individual fabric pockets, so each coil compresses alone. Pocket springs contour better and stop a partner's movement travelling across the bed. Bonnell remains the durable budget choice for kids and spare rooms. Is memory foam too hot to sleep on? Plain memory foam holds more heat than springs because air can't circulate through it. Gel-infused foam layers and breathable covers offset most of that, and spring-plus-foam hybrids like Euro tops split the difference. If you already run hot, choose a spring build or gel foam and use cotton bedding. What firmness should I choose? Match it to your sleeping position first: side sleepers suit medium to medium-soft, back sleepers medium-firm, stomach sleepers firm. Then adjust for weight, softer if you're lighter, firmer if you're heavier. The test that matters: lying in your normal position, your spine should stay in a straight, natural line. How much should I spend on a mattress in NZ? In our range, kids' and spare-room singles start at about $125. Everyday adult Queens run from about $220 to $930, with the most-bought models between $240 and $500, and the very top reaches about $1,080. Spend at the level the bed gets used: nightly adult beds deserve the middle tier. How long does a mattress last? A quality mattress used nightly is typically good for eight to ten years; budget builds and guest beds vary either side of that. Replace when you see sag that rotating doesn't fix, feel individual springs, or consistently wake sore. Rotating, airing, and a washable protector stretch the lifespan meaningfully. Do I need a bed base, or do slats work? Either works when matched to the mattress, but slats are the better default in NZ bedrooms because they ventilate the underside, which fights our damp winters. Keep slat gaps modest so foam mattresses stay supported evenly. A solid base feels slightly firmer and needs a more disciplined airing habit. What size is a King Single, and who is it for? A King Single is 107 × 203 cm: wider and 15 cm longer than a standard Single. It's the best single-sleeper size in NZ, ideal for teenagers, tall adults, and guest rooms that host one person. If a kid's room has the space, it's the upgrade that lasts through high school. Does body weight change which mattress I should buy? Yes. Firmness labels assume an average-weight sleeper, roughly 60 to 90kg. Lighter sleepers compress less, so choose a step softer than your position suggests; heavier sleepers should go a step firmer, with a thicker spring core for durability. Couples with a big weight difference do best on pocket springs. Keep exploring Related guides More from the TSB Living team.
