Thanks for choosing the Simba Green!

(You've done something seriously good).

Because your new Green mattress features all the cooler comfort Simba is famous for, with just half the carbon footprint of traditional hybrid mattresses.

So great sleep needn’t cost the earth. Not any more.

Best wishes,
The Simba Team

About your mattress

The Big Unboxing

We know you’re desperate to try your new mattress, but please remember it needs 6 hours to settle and reflate, and up to 72 hours to regain its shape fully.

Take your time

Our experts estimate it takes about 30 nights to get used to a new mattress, so just relax; our 100 night, comfort-exchange will give you plenty of time to get to know your Simba.

Continuing comfort

You don’t need to turn your mattress over, but we recommend you rotate it regularly to prolong its life; spin it 180 degrees on its base every month for the first 3 months, then every 3 months thereafter. Oh, and always use a mattress protector.

Simba Sleep Tip

4 7 8

If you struggle to drift off at night, try 4/7/8 Breathing to help you relax:

  • Breathe in deeply through the nose for 4 seconds
  • Hold your breath for 7 seconds
  • Breathe out, huffing air through the mouth for 8 seconds
