Frequently Asked Questions

Will an 11 inch king size mattress fit my 5ft frame?
A 5ft king size is the standard UK king dimension of 150 x 200cm. Measure inside your frame to confirm it matches, and allow only a small gap. At 11 inches deep, also check the headboard and sheets are suitable.
Who is this medium firm pocket sprung king size mattress for?
It suits couples and individuals wanting extra space with a supportive medium firm feel. Medium firm sits between soft and hard, so it can work for different sleeping styles. If you like very soft or very firm, consider other options.
What do pocket springs do for two sleepers on a king size?
Each spring sits in its own pocket and works independently, so one person moving causes less disturbance on the other side. On a 150cm wide bed this separate action helps the surface adapt to each sleeper rather than dipping across the bed.
How firm is a medium firm pocket sprung mattress?
Medium firm leans a little towards supportive while still offering some give. You should feel the springs holding you up without the surface feeling hard. Comfort is personal, so think about how firm you generally like your bed to be.
Does a spring mattress let air flow through the bed?
Yes, space around the coils lets air move through more freely than a solid foam core. This helps the mattress feel fresher. Warmth overnight still depends on your bedding, the room temperature and your own preferences.
How deep is an 11 inch mattress in centimetres?
Eleven inches is about 28cm, a fairly deep mattress. It suits most modern frames, but check your headboard height and that fitted sheets have deep pockets. Always confirm the exact depth in the listing before you order.
How does a king size sprung mattress compare with memory foam or hybrid?
A pocket sprung mattress feels more responsive and breathable than memory foam. Hybrid mattresses mix springs and foam layers. If you want springs as the main support with a medium firm feel, this sprung mattress is a natural choice.
How do I get a king size mattress into my bedroom?
Measure stairs, corners and doorways before delivery day, and arrange for two people to carry it. Unwrap it in the bedroom, lift it onto the base and allow a few hours for it to settle into full shape before you sleep on it.
How often should I rotate a king size pocket spring mattress?
Rotate it head to foot every few weeks in the first months, then roughly every two to three months. This spreads wear evenly. Use a firm, well supported base and keep the surface clean with a light vacuum.
What should I compare when buying a pocket sprung mattress in king size?
Compare the size, depth, firmness and construction against your frame and how you sleep. This 11 inch medium firm option is a supportive choice. Check the full listing details so the mattress suits your bed and your bedroom.
