Mattress Sizes UK

At our UK store, we stock all standard mattress sizes — from compact 2ft 6" small singles to luxurious 6ft super kings. Each mattress is manufactured for comfort and durability, using quality materials that support your body night after night. Whether you prefer pocket sprung, orthopaedic, open coil, memory foam or latex, you’ll find the perfect fit for your bed and your lifestyle here.

2ft 6" Small Single Mattresses

A 2ft 6" small single mattress is perfect for box rooms, smaller bedrooms, or guest spaces where space is limited. It offers just enough room for one person, typically a child or young teenager, without overcrowding the room.

This size is often chosen for bunk beds, children’s first beds, or narrow guest rooms. It’s a practical, budget-friendly option when you need a comfortable mattress that makes the most of every inch of space.

3ft Single Mattresses

The 3ft single mattress is the UK standard for one adult or a growing teenager. It provides extra width compared to a small single, giving more comfort and better sleep quality.

It’s a great choice for single sleepers, student rooms, and guest bedrooms. If you want a versatile, easy-to-fit mattress that works in almost any room, the single is ideal.

3ft 6" Large Single Mattresses

A 3ft 6" large single mattress gives you more width than the standard single, offering extra comfort without taking up much more space. It’s perfect for solo adults who move around in their sleep or want a roomier feel.

This size is also ideal for care settings or hospital-style beds, providing greater ease of movement while maintaining support and comfort.

4ft Small Double Mattresses

Also known as a three-quarter mattress, the 4ft small double sits neatly between a single and a standard double. It’s a favourite for solo sleepers who like more space, or for couples who don’t mind being close.

It fits beautifully in smaller master bedrooms, flats, and guest rooms. Many people pair this size with a storage bed frame to save space while keeping a comfortable sleeping surface.

4ft 6" Double Mattresses

The 4ft 6" double mattress is the most popular size in the UK. It’s the perfect balance of comfort and practicality — wide enough for two adults, yet compact enough for most bedrooms.

Many single sleepers also choose this size for the extra space to stretch out. Whether you prefer a soft, medium, or firm feel, our double mattresses come in every comfort level imaginable.

5ft King Size Mattresses

A 5ft king size mattress offers generous space for two people to sleep without disturbance. It’s a popular upgrade for couples who value a peaceful, unrestricted night’s rest.

King size mattresses look impressive in larger rooms and are available in various materials and comfort types — from cooling gel to luxury pocket sprung designs. They’re the perfect blend of comfort and elegance.

6ft Super King Size Mattresses

The 6ft super king mattress is the largest standard size in the UK. It’s perfect for couples who want plenty of personal space or families who share the bed with children or pets.

It delivers an unmistakable sense of luxury, ideal for large master bedrooms. A super king mattress turns your home into a five-star sleep retreat — spacious, supportive, and indulgently comfortable.
