A double mattress measures 135 x 190cm and gives two adults around 67cm of personal space each - enough for most couples in a smaller bedroom, and the most practical choice for a main bedroom where a king size will not comfortably fit. At Land of Beds, we've been helping people across the UK find the right mattress for over 50 years. Whether you want a pocket spring that minimises how much you feel your partner move, memory foam for pressure relief at the shoulders and hips, a hybrid that gives both of you the best of both constructions, or a luxury handcrafted mattress built to last a decade in a main bedroom, our double mattress range covers every need.

A double mattress is what most people buy when they need a mattress. It fits the most common UK bed frame size, suits couples in smaller bedrooms, and works equally well for a solo adult who wants more room than a single provides. The question is not usually whether to buy a double - it's which double is right for how you sleep, and whether the room and budget should prompt a look at king size instead. At Land of Beds, we've been helping people work through this for over 50 years, with honest advice and no pressure to buy.
Three things determine whether a double mattress is the right choice. Get these right and narrowing down brand and price becomes straightforward.
| Factor | Why It Matters | What to Check |
|---|---|---|
| Is double the right size? | In a standard double, two adults each have around 67cm of personal space - less than a single bed each. That's enough for many couples, but it's worth checking the room can also take a king before committing. | Room dimensions, whether a king size fits comfortably, how much both partners move during the night |
| Construction type | Construction determines how the mattress feels, handles heat, transfers movement between partners, and how long it performs. Getting this wrong is the most common cause of dissatisfaction. | Pocket spring vs memory foam vs hybrid vs latex, particularly the motion transfer difference for couples |
| Tension (firmness) | Couples often have different weight and sleep position preferences, which can make one tension wrong for one partner. The right tension for the bed depends on the heavier or more movement-sensitive sleeper. | Both partners' weights, sleep positions, and whether either sleeps warm |

A standard UK double mattress measures 135 x 190cm (4ft 6in x 6ft 3in). This is the size to use for all standard UK double bed frames.
| Dimension | Measurement | Notes |
|---|---|---|
| Width | 135cm (4ft 6in) | Gives two adults approximately 67cm each - less than a single bed in personal space terms |
| Length | 190cm (6ft 3in) | Suits sleepers up to approximately 5ft 10in. Taller sleepers should consider king size for the extra 10cm of length. |
| Typical depth | 20 to 35cm | Depth varies by construction. A deeper mattress is not always better - what matters is the quality of the materials inside. |
For couples who share a double regularly, it is worth measuring your room to see whether a king size fits before ordering. A king is 15cm wider and 10cm longer, and in a room that can take it, that difference is noticeable overnight. See our king size mattresses if you'd like to compare.

The construction of your double mattress shapes how it handles partner movement, temperature, pressure relief, and long-term durability. Here's a plain comparison of every type we stock in double size.
| Type | Key Features | Best For |
|---|---|---|
| Pocket Spring | Individually wrapped springs move independently; natural airflow; filling layers on top; responsive, buoyant feel | Couples wanting minimal motion transfer; hot sleepers; those who prefer a traditional, bouncy feel |
| Memory Foam | Contours closely to the body; excellent pressure relief; absorbs movement well; can retain heat unless gel-infused | Solo sleepers or couples where motion transfer is less of a concern; those with pressure point discomfort |
| Hybrid | Pocket springs with foam or latex comfort layers; combines airflow and edge support with pressure relief | Couples wanting the benefits of both; the most versatile double mattress construction for shared use |
| Latex | Naturally responsive and breathable; hypoallergenic; durable; heavier than foam | Hot sleepers; allergy-sensitive buyers; those wanting a long-lasting natural feel |
| Orthopaedic | Firmer construction for spinal alignment; available in pocket spring and foam bases | Adults with back concerns; heavier sleepers; those needing consistent firm support |
| Pillow Top | Extra comfort layer sewn onto the surface; adds softness on entry without altering the support core | Buyers who want a softer feel on first contact with a more supported base beneath |

One thing our team hears regularly: couples who bought a double because it fitted the room, then found themselves disturbing each other. In most cases, the issue is construction rather than size - a pocket spring or hybrid moves independently where a foam-only mattress carries movement across the whole surface. If partner disturbance is a current problem, construction is the first thing to address before changing size.
For couples sharing a double, tension is particularly important because two people of different weights and sleep positions are using the same surface every night.
| Tension | Best For | What It Does |
|---|---|---|
| Soft | Lighter sleepers under 60kg (9st 6lb); side sleepers needing shoulder and hip pressure relief | More sink-in; good pressure relief; may feel unsupportive for a heavier partner |
| Medium Soft | 60 to 75kg (9st 6lb to 11st 11lb); side and combination sleepers | Balances cushioning and support; suits most lighter couples |
| Medium | 70 to 90kg (11st to 14st 2lb); back and combination sleepers; the most popular tension for couples | Good all-round support with enough cushioning for most sleep positions |
| Medium Firm | 85 to 105kg; back and front sleepers; one heavier partner in a couple | Firmer surface for alignment; may feel too firm for a lighter partner |
| Firm | Over 100kg; front sleepers; those needing maximum support | Minimal sink; strong spinal support; often uncomfortable for lighter partners |
When two partners have significantly different weights, choosing a tension that suits the heavier or more movement-sensitive sleeper usually works better for both. If the difference is more than 20kg, ask our team about zip-and-link options in double-adjacent sizes.
The materials inside your double mattress determine how it feels, how long it lasts, and how it performs for different sleepers - particularly relevant for couples.
| Material | Performance and Maintenance | Best For |
|---|---|---|
| Pocket Springs | Independent spring movement reduces partner disturbance and improves airflow. Higher spring counts mean finer, more responsive springs. No maintenance beyond rotation. | Couples; hot sleepers; everyday main bedroom use |
| Memory Foam | Pressure-relieving and body-contouring. Durable. Can retain heat; gel-infused versions manage this better. Wipe-down only. | Solo sleepers or still couples; pressure point relief |
| Natural Fillings (wool, cotton, cashmere) | Breathable and temperature-regulating year-round. Found in mid-range to premium mattresses. | Temperature-sensitive sleepers; buyers wanting natural materials |
| Latex | Naturally responsive, breathable, hypoallergenic. Longer lifespan than foam. Heavier than other materials. | Hot sleepers; allergy-sensitive buyers; long-term use |
| Gel Foam | Actively draws heat away from the sleeping surface. Found in hybrid and foam constructions. | Hot sleepers; anyone who has found standard memory foam too warm |
See our Mattress Buying Guide for more on how construction affects long-term performance.
Your budget determines the materials, construction quality, and how long the mattress performs. A double in a main bedroom used every night by two people deserves more investment than one in a guest room used occasionally.
| Budget | What You Get | Best For |
|---|---|---|
| Under £300 | Entry-level pocket spring or foam. Reliable for lighter use. Shorter lifespan under daily use by two people. | Guest rooms; occasional-use double bedrooms; first-time buyers on a tight budget |
| £300 to £599 | Better spring systems, improved comfort layers, more tension choice, improved durability. | Secondary bedrooms; couples who want more comfort without the main bedroom price |
| £600 to £999 | Improved construction, natural filling options, stronger edge support, longer guarantees. Where most main bedroom double buyers land. | Everyday main double bedrooms; couples; buyers who want comfort to last 8 to 10 years |
| £1,000 and above | Premium and handcrafted construction, luxury natural fillings, extended guarantees. Built to last a decade or more. | Long-term investment; master bedrooms; those pairing with a quality divan base |
A quality mattress on a worn base will not perform as it should. If your existing base is over 8 years old, replacing both together is usually better long-term value.
Mike Murray, Land of Beds CEO: "The double mattress is the most common size in our showrooms, and the most varied in terms of what people actually need from it. A couple in their 30s using a double as their permanent main bed needs a completely different mattress from someone buying for a spare room. Treating them the same is how you end up with the wrong mattress."

If you're deciding between a double and a king, here's a plain comparison to help.
| Double Mattress | King Size Mattress | |
|---|---|---|
| Dimensions | 135 x 190cm (4ft 6in x 6ft 3in) | 150 x 200cm (5ft x 6ft 6in) |
| Space per person | Approximately 67cm each for two adults | Approximately 75cm each - more than a single bed |
| Length difference | 190cm - may feel short for taller sleepers | 200cm - 10cm longer, suits sleepers up to 6ft 3in |
| Room requirement | Minimum room width around 2.6m | Minimum room width around 3.0m |
| Best for | Couples in smaller rooms; solo sleepers wanting width; guest rooms | Couples wanting more personal space; taller sleepers; main bedrooms with more room |
If your room can take a king, it's almost always worth the upgrade for a couple. The 15cm of extra width makes a clear difference to how much each person feels the other move overnight. See our king size mattresses to compare.

| Question | Answer |
|---|---|
| What size is a double mattress in the UK? | A standard UK double mattress measures 135cm wide by 190cm long (4ft 6in x 6ft 3in). This fits all standard UK double bed frames. For two adults sharing, this gives each person approximately 67cm of space - less than a single bed each. |
| Is a double mattress big enough for two people? | It depends on the two people and the room. A double works well for couples in smaller bedrooms, or for those who sleep fairly still. If either partner moves a lot during the night, or if the room can take a king, upgrading to 150 x 200cm gives each person around 75cm and tends to make a noticeable difference to how much each disturbs the other. |
| What is the best double mattress for couples? | For couples, pocket spring or hybrid is almost always the better choice. Individually wrapped springs move independently, which means one partner's movement does not travel across to the other side. Memory foam carries less movement than open coil, but pocket spring and hybrid perform better for couples overall. Tension should be chosen based on the heavier partner's weight. |
| What is the best double mattress for back pain? | It depends on the nature of the back pain and the sleeper's weight. A medium to medium-firm pocket spring or hybrid suits most people with general back discomfort - firm enough to keep the spine aligned but not so firm it creates pressure points. For more specific guidance, call our team and we'll advise based on your sleep position and weight. |
| How long should a double mattress last? | A quality mid-range double mattress should last between 7 and 10 years under normal use. For two people sharing every night, construction quality matters more than for a guest room mattress - a better-built mattress holds its support for longer under the additional load. Using a protector and rotating as recommended both help extend the lifespan. |
| Should I buy a double or king size mattress? | Measure your room first. A king is 15cm wider and 10cm longer than a double. If the room allows a king with comfortable clearance on both sides, it is almost always the better choice for a couple. If the room is too small to take a king comfortably, a double in the right construction often works just as well. See our king size mattresses to compare. |
| Do you offer free delivery on double mattresses? | Yes. Free mainland UK delivery on orders over £100. Some remote postcodes may incur a charge - check at checkout. Lead times vary by brand. |
| Can I buy a double mattress on finance? | Yes. Finance is available on eligible orders, with interest-free options on selected terms. See our finance page for eligibility and how to apply. |
| What is the difference between double and king size? | A double mattress is 135cm wide by 190cm long. A king is 150cm wide by 200cm long - 15cm wider and 10cm longer. For couples, that extra width means approximately 75cm per person on a king compared to 67cm on a double. The length difference matters for anyone over 5ft 10in, as the extra 10cm brings the mattress to 200cm. |
| What is the best construction for a double mattress used every night? | For a main bedroom double used nightly, pocket spring or hybrid gives the best combination of durability, airflow, and long-term performance. Natural fillings (wool, cotton) added to a pocket spring base improve temperature regulation significantly. For a guest room, an entry-level pocket spring or open coil is adequate. |
