Wake up rested and ready to take on the day with a mattress that truly fits your body and your bedroom.
Our collection includes all standard mattress sizes UK, each made with high-quality materials and excellent craftsmanship. From space-saving 2ft 6" small singles to generous 6ft super kings, every mattress is built to provide the ideal balance of comfort and support.
Choose from pocket sprung, orthopaedic, open coil, memory foam, or latex mattresses — all designed to help you enjoy deeper, more restful sleep every night.
A 2ft 6" small single mattress is perfect for box rooms, compact bedrooms, or guest spaces where every inch counts. Designed for one sleeper, it’s a popular option for children, teenagers, and smaller adults.
Lightweight and easy to move, this size also suits bunk beds or smaller divan bases. If you’re after an affordable, space-saving choice that still feels comfortable, the small single is ideal.
The 3ft single mattress is the standard UK size for one adult or a growing teen. It offers extra width compared to a small single, giving more room to move and a better night’s rest.
Perfect for single sleepers, spare rooms, and student accommodation, it fits almost anywhere while delivering solid comfort and support.
A 3ft 6" large single mattress gives a little more width than a regular single, creating a more spacious feel without taking up too much room.
This size works well for solo adults who value comfort and space or for care environments where additional room to move is needed. Supportive and practical, it’s a smart in-between option.
Also known as a three-quarter mattress, the 4ft small double bridges the gap between a single and a standard double. It’s a favourite for solo sleepers who love extra space or for couples who don’t mind being close.
Compact yet comfortable, it’s ideal for smaller master bedrooms, flats, or guest rooms where space is limited but comfort still matters.
The 4ft 6" double mattress is the most popular size in the UK — roomy enough for two, yet compact enough for most bedrooms.
Many single sleepers choose a double for added comfort and the luxury of stretching out. Available in soft, medium, and firm feels, our double mattresses suit all preferences and sleeping styles
A 5ft king size mattress offers generous space for two people to sleep peacefully without disturbing each other.
It’s an excellent upgrade for couples who value comfort and personal space. King size models look elegant in larger bedrooms and come in a range of materials, including luxury pocket sprung and breathable memory foam options.
The 6ft super king mattress is the ultimate in sleeping luxury. With plenty of room for couples, families, or anyone who simply loves space, it brings hotel-style comfort to your home.
Ideal for big bedrooms, this size offers unbeatable relaxation and indulgent comfort — perfect for those who want the very best night’s sleep possible.
