The dimensions of a double Sleep+ Mattress are 138.5cm in width x 190cm in length, making it a space-efficient design perfect for more compact bedrooms, guest rooms, or children’s rooms.

When deciding between a double or a queen Sleep+ Mattress, the key difference lies in their proportions. A double mattress is approximately 14cm narrower and 13cm shorter than a queen mattress, making it a practical choice for compact bedrooms or guest rooms, without compromising on comfort.

Compared to a king single Sleep+ Mattress, a double mattress offers around 33cm more width, while the king single provides an additional 13 cm in length. This makes the king single mattress size the preferred choice for taller, solo sleepers, whereas a double mattress can sleep two people more comfortably.
