Foam? Springs? Why not both?

  • Foam Mattress

    Soft but sinky

    Responsive and comfortable but can be too soft and hot.

  • The Simba Hybrid®

    The best of both worlds

    Cloud-like comfort
    Cooling airflow
    No motion transfer
    The right support

  • Spring Mattress

    Firm but bouncy

    Supportive and breathable but can be too firm and bouncy

Five layers of perfect comfort

Each layer is uniquely designed to work in harmony with the others - and with you.

Simba mattress layers
Breathable sleep surface

Our zip-off, washable and hypoallergenic sleep surface is soft to the touch and easy to clean.

Cooling comfort layer

Our open cell Simbatex foam tackles overheating by increasing airflow, while also layering on comfort.

Supportive pocket springs

Our conical springs cradle your body from top to toe and minimise disturbance between couples.

Edge to edge support

Our Edge Lift technology means no matter where you lie on your mattress you'll feel fully supported.

Responsive memory foam

We’ve added a layer of Visco memory foam which moulds to your body for more restful sleep.

Zoned base

Our durable base has been engineered to give you pressure relieving support in all the right places.

Press & awards

"For quite some time now, our favourite mattress has been the excellent Simba hybrid memory foam pocket spring mattress."

"Good Housekeeping testers found it a complete 'dream to sleep on' and are all Simba converts."

"If you're in the market for a 'bed-in-a-box' mattress, I can wholeheartedly endorse the Simba Hybrid."

"If you prefer to be cosseted by a cloud-like mattress but your partner yearns for one that's on the firm side, then this 'fits-all' mattress, might well be the answer."
