All of our mattresses are compressed, rolled, vacuum packed, boxed, and delivered to our customers door-to-door. We have invested heavily in the most advanced automated moving systems. Our compressed and high-quality mattresses allow our customers to easily move and install mattresses whilst reducing the risk of damage during transportation. The roll packing will not affect the quality of the mattress. Customers can easily take the mattress out of the box and unwrap the plastic wrap to allow air to enter the mattress.

Installing the Sleep Happy mattress is easy:

  1. Bring the mattress to the room where you would like to install it. 
  2. Place the box flat on the floor and gently take the rolled up mattress out of the box 3.Carefully cut the outer plastic layer, ensuring that the scissors do not touch the mattress
  3. On your bed or the base of your mattress, slowly roll out the mattress and cut off the second layer of plastic. Be sure to keep this plastic in case you intend to return the item. 

Our Sleep Happy mattress will be ready for you to use in 5 minutes. However, it can take up to 24 hours to fully expand. Please see the additional video below for detailed instructions on how to unpack your mattress.
