King

Sealy’s King size mattress is perfect for those who prefer more space while they sleep. Measuring 183cm in width and 190cm in length, it ensures that you can have a restful night’s sleep, particularly if you have young children joining you in bed. If you have a spacious bedroom, there’s nothing quite like a Sealy’s King size mattress. The mattress is supported by two separate bases, which minimizes partner disturbance when getting in and out of bed. This feature makes King size beds an excellent choice for restless sleepers, early risers, and shift workers.

Sealy’s Super Singles are an excellent solution for holiday homes and guest rooms, where two beds can be combined to create a King size bed or split to accommodate additional adults and children comfortably.

Single

Sealy’s Single size mattress is an excellent option for both children and adults. Measuring 91cm in width and 190cm in length, they provide ample space for individuals of all ages. While they are ideal for a child’s first bed, they also offer enough room for adults to move comfortably during the night. In fact, a single bed provides as much space for one person as a king size bed does for two people. Furthermore, single beds are a practical solution for those who wish to save space, as their compact dimensions can fit into any bedroom.
