Thinking about a double bed for your flat, guest room or first home? This guide walks you through what a double bed really is, how it works, the common types you’ll find in New Zealand, clear pros and cons, and a step-by-step way to choose the right one. Read on to make a confident decision—without the jargon.

What is

A double bed is a mattress and base combination designed to sleep one or two people. In many places it’s also called a “full” bed. It sits between a single and a queen in size: big enough for two people who don’t need a lot of personal space, or for one person who wants extra room to stretch.

Typical New Zealand dimensions (standardised in many stores):

• Double: about 137 cm x 188 cm (54″ x 74″)
• Queen: about 153 cm x 203 cm (60″ x 80″)
• King: about 183 cm x 203 cm (72″ x 80″)

These are common guides rather than absolute rules: some manufacturers use slightly different measurements. Always check the exact dimensions before you buy, especially for fitted sheets and bedframes.

How it works

A double bed works by combining two main elements: the mattress (the comfort layer) and the base or frame (the support). Each element affects comfort, durability and how the bed fits your room.

Mattress layers and support

• Comfort layer: foam, latex or pillow-top that shapes to the body.
• Support core: springs, pocket coils or dense foam that keep the spine aligned.
• Cover: the fabric and quilting that sit on top and affect feel and breathability.

Different constructions change how a double bed performs. Pocket springs reduce motion transfer, memory foam contours more closely, and latex offers a bouncy, natural feel. The base—slatted, platform or divan—affects ventilation and mattress lifespan.

Why size matters

Room size, sleeping partners and storage needs determine if a double bed is the right choice. A double bed frees up floor space compared with a queen or king, making it a practical choice for smaller Wellington apartments or Christchurch flatmates.

Types / examples

When people talk about a double bed, they’re often choosing between several mattress constructions and frame styles. Below are the common options you’ll see in NZ stores and online.

Mattress types

• Innerspring: traditional, firm support and good airflow.
• Pocket spring: each spring works independently for better motion isolation.
• Memory foam: contours the body and reduces pressure points.
• Latex: responsive, durable and naturally breathable.
• Hybrid: layers of foam over springs to combine support and comfort.
• Airbeds: adjustable firmness but need pumps and maintenance.

Frame styles

• Platform bed: simple, low-profile base with solid support.
• Slatted base: common and breathable; check slat spacing for foam mattresses.
• Divan with drawers: storage built in underneath, useful for small homes.
• Adjustable base: raises head or feet; good for reading or health needs.
• Upholstered frame: adds a headboard and a softer look.

Example uses

• Guest room: a double bed is compact and economical while still comfortable.
• Studio apartment: saves floor space compared with a queen or king.
• Growing families: a double can work for a child or teen transitioning from a single.

Pros and cons

Below are the main advantages and disadvantages of choosing a double bed, kept short so you can scan quickly.

Pros

• Saves space in smaller rooms.
• Typically cheaper than queen or king sizes.
• Easier to move and fit through doorways and stairwells.
• Suits single sleepers who prefer more room than a single bed.

Cons

• Limited personal space for two adults—can feel cramped.
• Taller sleepers may find the length restrictive if under 188–190 cm is used.
• Fewer sheet and bedding options compared with queen/king in some stores.

How to use or choose

Choose a double bed by matching size, comfort, and budget to your needs. Follow this step-by-step process to make sure you pick the right one.

1. Measure the room: leave at least 60–75 cm clear space around the bed for walking.
2. Decide who sleeps in it: single sleeper, couple or occasional guests.
3. Test mattress feel: lie down for 10–15 minutes in the store if you can.
4. Check mattress construction: note warranty length and materials (foam, spring, latex).
5. Choose a base: do you need storage, a low-profile frame, or adjustable features?
6. Confirm delivery and returns: ask about setup, removal of old bed, and return windows.
7. Buy correct bedding sizes: fitted sheets for double sizes and protectors that match.

Quick tips:

• Measure doorways and stairwells to ensure the bed fits during delivery.
• For foam mattresses, check slat gap—too wide a gap can void the warranty.
• Use a mattress protector to extend life and keep warranty valid.

Comparison: Double vs Queen vs King

Bed size	Typical NZ dimensions	Best for	Space per person
Double bed	137 cm x 188 cm	Small master rooms, guest rooms, single sleepers who want extra space	About 68.5 cm each if shared by two people
Queen	153 cm x 203 cm	Most NZ couples and couples with a small room	About 76.5 cm each
King	183 cm x 203 cm	Couples who want maximum personal space	About 91.5 cm each

FAQ

Is a double bed big enough for two people?

Yes, but it can feel tight. A double bed suits couples who sleep close together or who don’t need much personal space. For more comfort, consider a queen.

What bedding sizes fit a double bed?

Buy sheets labelled “double” or “full”. In NZ stores, fitted sheets sized to double will fit the mattress depth too—check depth for deep foam mattresses.

How do I measure my room for a double bed?

Measure floor length and width. Add space for bedside access—ideally 60–75 cm on at least one side and the foot of the bed.

Can a double bed fit in a small flat?

Yes. A double bed is often the best compromise between sleeping space and available floor area in small flats.

What mattress type is best for a double bed?

There’s no single best. Choose pocket springs for couples who feel each other’s movements, memory foam for pressure relief, and latex for durability and natural breathability.

How long should a double mattress last?

With regular rotation and a good base, expect 7–10 years for many mattresses. Warranty periods vary—read the fine print.

Do I need a special base for memory foam?

Not always. Memory foam needs even support—slatted bases are fine if slat gaps are small (usually under 7 cm). Solid platforms also work well.

Final thoughts

A double bed is a practical, space-saving choice that suits many New Zealand homes. It’s affordable, easier to manoeuvre, and a smart pick for guest rooms or smaller master bedrooms. Measure carefully, test mattress types, and check the base and warranty before you buy. With the right choices you’ll get comfort and durability without wasting space or money.
