King Size Mattresses

King Size Mattresses in Glasgow

King size mattresses are a popular choice for customers who want more sleeping space than a standard double mattress. At Clyde Beds, this collection includes 5ft king size mattresses suitable for king beds, divan bases, bed frames and larger main bedrooms.

A standard UK king size mattress measures 150cm x 200cm, also known as 5ft x 6ft6. Compared with a double mattress, a king size mattress is both wider and longer, making it a practical upgrade for couples, taller sleepers and anyone who wants extra room.

If you are replacing an old mattress, measure your existing bed base before ordering. A king size mattress should match a standard UK king bed frame or king divan base so it sits correctly.

Choosing the Right King Size Mattress

The best king size mattress depends on how the mattress will be used, your preferred comfort level and the type of bed base you already have. A mattress used every night in a main bedroom may need different features from one used in a guest room.

King size mattresses are often suitable for:

• Main bedrooms
• Couples wanting more space
• Taller sleepers
• Single sleepers wanting extra room
• Customers upgrading from a double mattress
• King size divan beds
• King size bed frames

Open Coil King Size Mattresses

Memory Foam King Size Mattresses

Memory foam mattresses usually provide a cushioning foam feel and may suit customers looking for a more contouring sleeping surface.

Pocket Sprung King Size Mattresses

Pocket sprung mattresses use individually pocketed springs and may offer a more responsive feel than traditional open coil mattresses.
