About your mattress

The Big Unboxing

It’s a good idea to unfold your new GO mattress and lay it flat on your bed frame before you cut the plastic wrapping; it springs back into shape quite quickly, so make sure you (and any fragile accessories such as lamps) aren’t in the way. Then be patient if you can; it takes about 6 hours to settle and reflate, and up to 72 hours to regain its shape fully.

How to recycle your mattress packaging:

The cardboard can be placed in curb side recycling, but the plastic wrapping should be placed in your normal refuse. We know this isn’t ideal, but using this wrapping allows us to deliver our mattresses boxed, resulting in efficiencies in the carbon footprints of both our delivery and warehouse logistics. We’ll be introducing a biodegradable alternative soon, but in the meantime the plastic wrap is still our most sustainable option.

Take your time

Our experts estimate it takes about 30 nights to get used to a new mattress, so just relax; our 200-night, risk-free trial 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.
