Firm-leaning support with a cushioned finish: the 12 inch 7-zone orthopaedic hybrid mattress in 5ft king is built for couples who want a supportive, deep king.

Orthopaedic feel, king-size space

Orthopaedic styling generally means a firmer, more supportive feel that helps keep the spine aligned. Seven zones vary support across the mattress, while the hybrid construction adds spring airflow and a comfort layer on top, all in a deep 30cm build.

Who it suits

Back sleepers, couples who prefer a firmer surface, and people replacing a soft or sagging mattress who want something more supportive.

Practical points

At about 30cm deep, check the frame headboard height and use deep fitted sheets. The mattress is heavy, so plan for two people.

Specification

  • Size: 5ft king (approx. 150 x 200cm)
  • Depth: 12 inches (approx. 30cm)
  • Support: 7 zones, orthopaedic style
  • Construction: hybrid

Frequently asked questions

Does orthopaedic mean medically approved?

No. It describes a firm, supportive style of mattress, not a medical certification. If you have a health condition, speak to a healthcare professional.

Is it too firm for side sleepers?

The comfort layer softens the surface, but side sleepers who prefer a plush feel may want a softer option.

What does the zoning do?

It adjusts support through different areas of the body, such as the shoulders, hips and legs.

What bedding fits?

Deep fitted king sheets of 30cm or more.

Should I rotate it?

Usually rotate head to foot every few months rather than flipping; check the care label.

Frequently Asked Questions

What is a 12 inch 7-zone orthopaedic hybrid mattress in king size?
It is a king size hybrid mattress about 12 inches deep with a seven-zone spring unit and a firm, supportive orthopaedic-style feel. Orthopaedic here describes the comfort level of the mattress. Check your frame and headboard clearance and the firmness on the product page before ordering.
How wide and long is a 5ft king size orthopaedic hybrid mattress?
A 5ft king is about 150cm wide and 200cm long. That gives two people a generous sleeping area and is a good size for master bedrooms where a king size hybrid mattress will not crowd the room.
Will this king size orthopaedic mattress fit my bed frame?
It suits frames with an internal sleeping area of about 150cm by 200cm. Measure inside the frame rather than the outside edges, and make sure the room has space to manoeuvre a king size mattress into place.
Who should choose an orthopaedic-style hybrid king mattress?
It suits sleepers who like a firm, supportive surface and find soft mattresses too yielding. Back and stomach sleepers often prefer this type of feel. As with any mattress, it is a personal comfort choice, so check firmness and depth on the product page before you order.
How do the seven zones shape the support of this mattress?
The spring unit is divided into seven zones that respond differently along the length of the body. The result is firmer support in the heavier central area and slightly gentler support near the shoulders and legs.
How firm is an orthopaedic 7-zone hybrid?
Orthopaedic-style hybrids are made to feel firm and supportive, with a flatter and more upright feel than plush mattresses. Check the exact firmness listed on the product page, and consider your sleeping position before ordering.
Does a spring hybrid king mattress keep cooler than all-foam?
Generally it does. Spring layers allow air to circulate around the mattress, while all-foam mattresses can retain more heat. A king size hybrid mattress with a spring core is therefore a sensible pick for sleepers who run warm.
Does a 12 inch deep king mattress work with my headboard?
A 12 inch mattress is about 30cm deep, so it sits fairly high on the bed. Measure the height of your headboard and frame sides to make sure you keep enough clearance behind your pillows.
What bedding is right for a 5ft king hybrid mattress?
Use king size bedding, including fitted sheets with a deep pocket suitable for a 12 inch mattress. A standard sheet may not reach around the corners, so check the stated depth on the packaging.
How do I handle delivery and compare it with pocket sprung or memory foam?
King size hybrids are heavy, so arrange help to carry yours and unwrap it flat. Compared with memory foam it is more responsive, and compared with plain pocket sprung it adds foam comfort. Rotate it every few months.
