Spacious, supportive, and built for comfort — our 3ft 6 large single mattresses are the ideal choice for anyone who wants more room without taking up too much space. A large single mattress gives you an extra six inches of width compared to a standard 3ft single, making it perfect for adults, teenagers, or anyone who likes to stretch out at night.
Each mattress is made to deliver the perfect balance of comfort, quality, and support. Ideal for solo adults who prefer a roomier feel or for use in guest and hospital-style beds, our 3ft 6 large single mattresses combine extra space with long-lasting performance.
Whether you choose firm orthopaedic support or the soft cushioning of memory foam, every mattress in our collection is designed to help you wake up refreshed.
1. More space to sleep comfortably
A large single size is six inches wider than a standard single, offering extra room to move without taking over your bedroom.
2. Ideal for adults and older teenagers
The 3ft6 large single mattress is great for solo sleepers who want additional comfort and freedom of movement — especially those who find a standard single too narrow.
3. A smart choice for guest rooms
If you have guests staying regularly, a 3ft 6 mattress ensures they sleep comfortably while still fitting neatly into smaller spaces.
4. Premium comfort and support
Choose from open coil, pocket sprung, or memory foam designs — all made with breathable fabrics and durable fillings for a perfect night’s rest.
5. Affordable quality
Our mattresses deliver outstanding comfort and quality at prices you can afford, with fast UK delivery available on all models.
A large single mattress measures 3ft 6" wide x 6ft 3" long (107cm x 190cm). It offers noticeably more width than a standard 3ft single, giving one person plenty of personal sleeping space without needing a full double bed.
This makes it ideal for spare rooms, adult single sleepers, or care environments where comfort and accessibility are essential.
Whatever your comfort preference, our collection includes a large single mattress for you:
Memory Foam: Gently adapts to your body’s shape and weight.
Pocket Sprung: Offers responsive, motion-isolating support.
Open Coil: Reliable everyday comfort at an affordable price.
Orthopaedic: Firm and supportive for better spinal alignment.
All 3ft 6 large single mattresses are made using quality materials for long-term use and comfort.
A large single mattress is the ideal middle ground between a standard single and a small double. It’s popular for solo adults, older teens, and care settings — anywhere comfort and practicality are equally important.
Each mattress is made for durability and comfort, ensuring you get a restful night’s sleep for years to come.
