What is a Double Bed Mattress?
Understanding the dimensions
A double mattress is one of the most popular mattress sizes in the UK. It typically measures 135cm in width and 190cm in length. This size offers ample space for single sleepers who want extra room or couples who prefer a cosy sleeping arrangement. The dimensions perfectly balance comfort and space efficiency, making it a versatile choice for many households.
Why double beds are popular in the UK
Double beds are a favourite in the UK for several reasons. They fit comfortably in most bedrooms, even in smaller homes or flats. They provide enough space for two people without taking up too much floor area. Additionally, double beds are often more affordable than larger sizes like a king or super king, making them a practical choice for budget-conscious buyers.
Standard Double Bed Mattress Size UK
Exact measurements explained
The standard double mattress in the UK measures 135cm x 190cm. This size is widely available and compatible with most bed frames and bedding sets. However, these dimensions are specific to the UK, and mattress sizes can vary in other countries.
How it compares to other sizes
A double mattress offers significantly more space than a single mattress (90cm x 190cm). However, it's smaller than a king size (150cm x 200cm) or super king (180cm x 200cm). If you're unsure which size to choose, consider your room dimensions and how much space you need for comfortable sleep.

Small Double Bed Mattress Size
Key dimensions and uses
A small double mattress, also known as a three-quarter mattress, measures 120cm x 190cm and is slightly narrower than a standard double. It's ideal for those who want more space than a single bed but have limited room to spare.
Ideal for compact spaces
Small double mattresses are perfect for compact bedrooms, studio flats, or guest rooms. They provide enough space for one person to stretch out or for two to sleep cosily. A small double could be the perfect solution if you're tight on space but still want comfort.
Choosing the Right Double Bed Mattress
Factors to consider
When choosing a double mattress, consider your sleeping position, body weight, and any specific needs, such as back support or allergy-friendly materials. Also, consider the mattress's firmness level, material, and durability.
Firmness levels explained
Luxury Mattresses come in various firmness levels, from soft to extra firm. Side sleepers often prefer softer mattresses for pressure relief, while back sleepers may benefit from medium-firm options. Stomach sleepers usually need firmer mattresses to maintain proper spinal alignment.
Types of Double Bed Mattresses
1. Memory foam mattresses
Memory foam mattresses are famous for their body-contouring support. They mould to your body shape, providing excellent support and pressure relief. These mattresses are ideal for those who suffer from joint pain or prefer a plush sleeping surface.
2. Pocket sprung mattresses
Pocket-sprung mattresses are made up of individual springs, each housed in its own fabric pocket. This design allows for targeted support and reduces motion transfer, making them a great choice for couples.
3. Hybrid mattresses
Hybrid mattresses offer the perfect blend of comfort, with layers of memory foam and pocket springs. They offer foam comfort with spring support, making them a versatile option for all sleepers.

Double Bed Mattress for Different Sleepers
Best for side sleepers
For side sleepers, a mattress should provide ample cushioning for the shoulders and hips. A medium-soft memory foam or hybrid mattress is often the best choice.
Ideal for back sleepers
Back sleepers require a mattress that supports the natural curve of their spine. A medium-firm pocket sprung, or hybrid mattress works well.
Options for combination sleepers
Combination sleepers who change positions during the night benefit from a responsive mattress, such as a hybrid or pocket-sprung option.
