Deep, cushioned and still supportive: the 12 inch memory foam spring hybrid mattress in 4ft6 double is for couples and solo sleepers who want a mattress that feels as good as it looks.

Two technologies, thirty centimetres

At around 30cm tall, there is room for a real spring core and generous memory foam layers. The springs give lift, airflow and a little bounce, which many people prefer to the stuck-in feel of all-foam beds. The foam above relieves pressure at the shoulders, hips and knees.

Who it suits

Sleepers who find all-foam mattresses too warm or slow to respond, couples who want a plush main-bedroom bed, and anyone upgrading from a thin spring mattress.

Practical points

A 30cm mattress needs deep fitted sheets and a frame with a suitably tall headboard. It is also heavy, so plan for two people when moving it.

Specification

  • Size: 4ft6 double (approx. 135 x 190cm)
  • Depth: 12 inches (approx. 30cm)
  • Construction: memory foam and spring hybrid

Frequently asked questions

Why choose a hybrid instead of all-foam?

Hybrids add spring airflow and responsiveness, which many people find cooler and easier to move on than dense foam.

Will it be too tall for my bed frame?

Check the headboard height and any frame depth limits. At about 30cm it sits taller than standard mattresses.

What sheets should I buy?

Fitted sheets with a deep pocket of 30cm or more.

Is it comfortable for two?

Yes. The foam layer absorbs movement and the 135cm width suits most couples.

How long should it last?

With a protector and regular rotation, a hybrid like this typically lasts several years.

Frequently Asked Questions

What is a 12 inch memory foam spring hybrid mattress?
It is a mattress about 12 inches deep, which is roughly 30cm, that pairs a spring unit with memory foam. The springs supply support and airflow while the foam adds contouring comfort, giving you the benefits of both constructions in a hybrid double mattress.
What size is a 4ft6 double hybrid mattress in centimetres?
A 4ft6 double is a standard UK size of about 135cm wide by 190cm long. This hybrid mattress double suits couples who like a compact bed and is a very common size for main bedrooms and guest rooms alike.
Will a 4ft6 double hybrid mattress fit my existing double bed?
If your frame has an internal space of around 135cm by 190cm, it should fit. Measure the inside of the frame, not the outside, and allow a small gap so the double hybrid mattress can be laid flat without forcing.
Who should choose a memory foam and spring hybrid double?
It suits sleepers who want the cushioning of foam without losing the lift and bounce of springs. Couples, side sleepers and anyone moving on from an old spring mattress often like this blend, as it feels familiar yet a little more comfortable.
How do the springs and memory foam work together here?
The springs form the supportive base and respond to movement, while the memory foam layers above soften the surface and contour to your shape. This stack is why a hybrid often feels both supportive and comfortable compared with all-foam or all-spring designs.
How firm will this hybrid mattress feel?
Comfort is personal, but hybrids of this type usually sit around a medium feel, firmer than pure memory foam yet softer than a bare spring bed. The product page lists the stated firmness, so check it against how you like to sleep.
Is this hybrid more breathable than all-foam mattresses?
Typically it is. The open spring layer lets air circulate through the mattress, which helps dissipate heat, whereas a solid memory foam block tends to trap it. If you sleep warm, that airflow is one of the main reasons to choose a hybrid.
Will a 12 inch deep mattress clear my headboard?
At about 30cm deep it is a taller mattress, so it rises higher above the frame. Check that your headboard and frame sides are tall enough, and that you can still get into bed easily, before you order a 12 inch hybrid.
What bedding size do I need for a 4ft6 double?
Buy double bedding, which is the standard size for a 135cm wide bed. Because this mattress is deep, choose fitted sheets that state a deep or extra deep pocket so the corners stay in place and the bed looks tidy.
How is it delivered, and how should I look after it?
Hybrid mattresses are heavy, so have a second person help carry it and unwrap it flat in the bedroom, letting it settle for a day. Rotate it head to foot every few months, and air the room regularly to keep it fresh.
