Frequently Asked Questions
What are the dimensions of this 12 inch firm orthopaedic hybrid for a 5ft king bed?
It is a 5ft king size, 150 x 200cm, and approximately 12 inches deep, or 30cm. It fits a UK king bed frame with matching internal measurements. Check your frame before buying and allow for the mattress height.
What does orthopaedic mean on a king size mattress?
We use orthopaedic to describe a firm, supportive style of mattress, and it makes no health claim. Check the firmness notes on the product page and compare with medium and soft options to decide what suits the way you sleep.
How do the 7 zones help support different parts of the body?
Zoned support divides the mattress into sections, such as head, shoulders, hips and legs, with the springs arranged to support each area differently. Seven zones is meant to give a more targeted feel than a mattress with the same support everywhere.
What does a firm orthopaedic hybrid feel like to sleep on?
Expect a stable, supportive surface with limited sink, backed by a springy core. It is firmer than medium models, but a hybrid still has some top-layer cushioning. It may suit those who prefer feeling held up rather than wrapped.
Is a 12 inch hybrid king size mattress warm to sleep on?
The spring section lets air pass through, so hybrids tend to sleep fresher than all-foam designs. A firmer surface also means you sit on top more than sink in. Warmth is still affected by your duvet, pyjamas and room temperature.
Do I need a special frame for a firm king size mattress this deep?
No special frame is needed, but it should have a sturdy base, with slats not too far apart, or a solid platform. Check the side height for a 12 inch mattress and make sure the mattress will not sit awkwardly against the headboard.
What fitted sheet depth is right for a 12 inch king mattress?
Look for king size 150 x 200cm fitted sheets with a pocket of 30cm or more. A shallower sheet can ping off the corners as you move. A deep, snug fit keeps the sheet flat and makes bed-making much quicker.
Can I move a firm orthopaedic king size mattress around easily?
Firm hybrid mattresses are heavy and do not fold well, so lifting needs two people and planning. Measure corners and stairs first. Once in the bedroom, remove the packaging and give it time to reach full shape before you sleep on it.
How do I make a firm hybrid king mattress last?
Rotate it regularly so wear spreads evenly, keep the base supportive and air the mattress whenever you change the sheets. Try not to sit on the very edge for long periods, since this can wear the perimeter more quickly.
Is a firm hybrid better than an all-foam firm king size mattress?
It depends on feel. A firm hybrid has a springy, breathable character, while an all-foam firm mattress is quieter and more cushioned. If you like support with airflow, a hybrid suits well. If you want silence and contouring, foam may appeal more.
