Incredible Review Image


We moved back to Oz after two years in the UK and needed a bed. Saw the Choice reviews and they weren’t wrong. It’s absolutely great and the service has been quick and amazing.

My nights are more comfortable with sleeping duck! Review Image

My nights are more comfortable with sleeping duck!

Enjoying much better nights sleep with sleeping duck, the absence of aches and pains in the morning is also a big benefit from the change of mattress. Would highly recommend.

It’s been a god send to be able to adjust the firmness during each trimester and after birth.

Sleeping Duck is cool Review Image

Sleeping Duck is cool

Sleeping Duck is really cool, less heat coming from the mattress provides the opportunity for a deeper sleep.

Couldn't be more impressed Review Image

Couldn't be more impressed

The mattress has been great from the day it arrived. Sooo comfortable. I got a firm but it stills feels nice and plush.

Best decision ever made Review Image

Best decision ever made

I bought 2 x single mattresses for my kids (teenagers) as their existing ones were so old. It was the best decision we ever made.


Amazing Edge Support! Review Image

Amazing Edge Support!

My daughter jumps into the queen size bed with my husband and I every night - I sleep right on the edge and it feels like I’m in the middle of the mattress!
