What's in this collection
The single mattresses here include pocket spring and memory foam options, with some combining both constructions in a hybrid format.
Pocket spring mattresses use individually wrapped coils that move and respond independently. This makes them adaptable across different body weights and sleeping positions, and the open spring structure allows air to circulate, which keeps the sleeping temperature consistent. For a child's room where the mattress will be used every night for several years, pocket spring is a reliable choice across a wide range of ages and sizes.
Memory foam compresses under body heat and weight to distribute pressure more evenly, which reduces load at the shoulders and hips. It suits side sleepers particularly well. Some mattresses here combine a pocket spring base with a memory foam comfort layer, giving pressure relief at the surface while retaining the airflow and support of a spring structure underneath. For a growing child who moves around during the night, a hybrid often provides a good balance.
Who a single mattress suits
The single is primarily a children's and guest room size. For a child from around school age through to the early teens, a single gives a proper sleeping surface without taking over the room. It works well in bedrooms where space matters, particularly where there's also a desk, wardrobe and the general accumulation of a child's belongings to accommodate.
For a single bed frame, the mattress sits at 90cm wide, which is comfortable for one person sleeping alone at most ages. The length at 190cm works for most people up to around 185cm, so for younger children and average-height adults it's completely adequate. Where it starts to feel limiting is for taller teenagers, or for a child who's growing fast and likely to need a new bed within a couple of years regardless. In that situation, a small double is often worth considering from the outset rather than replacing the single again in short order.
For a spare or guest bedroom, a single works well where the room is compact or where guests are typically one person rather than a couple. It's also a practical size for a bunk bed, which is a specific scenario worth noting below.
Single dimensions and practical fit
A UK single mattress is 90cm wide and 190cm long. This is the standard across all manufacturers, and any single mattress will fit any single base. The assembled bed once the frame is included typically measures around 95 to 100cm wide.
For room planning, a single bed fits comfortably in even a modestly sized child's bedroom, leaving room for furniture and floor space to play. As a guide, a room of around 2.2m x 2.8m or larger handles a single bed without feeling cramped.
Single mattresses and bunk beds are a common pairing and generally straightforward, with one thing to check: the depth of the mattress. Bunk beds have a safety rail around the upper bunk, and if the mattress is very deep it can sit above or close to the top of the rail, which reduces the effectiveness of that rail. Most standard bunk beds are designed for mattresses up to around 15 to 17cm in depth. Check the mattress depth listed in the product specification alongside the bunk bed's rail height before ordering, particularly for the upper bunk.
Spreading the Cost
Finance is available on many of our single mattresses, subject to status. It's worth knowing about even for what might seem like a smaller purchase. A child spends more hours in bed proportionally than an adult, and the quality of a mattress tends to affect how long it remains comfortable and supportive. Choosing a better-specified mattress for a child's room and spreading the cost is often the more practical approach than replacing a cheaper one sooner.
