All of our mattresses are rolled packed and delivered to our customers. We have invested heavily in the state-of-the-art, fully automatic roll packing machine to compress our high-quality mattresses. This allows us to make it easier for our customers to set the bed up, plus improving transport efficiency that lowers the risk of damage during transit. The roll-packing will not affect the quality of the mattresses. Once the mattress has been taken out, please shake it well from the bottom and allow it to fully open up within 24 hours.

Setting up your King Koil mattress is simple:

1. Move your King Koil to the desired room

2. Gently tip the box over to its side and slide the compressed mattress out

3. Carefully cut the outer plastic. Make sure not to cut the mattress.

4. On your bed frame or foundation, unroll and carefully cut open the remaining plastic to begin the decompression. Keep this plastic in case of a return.

Your King Koil is ready to enjoy after just 5 minutes, but it may take up to 24 hours to fully expand. Watch our videos below for details (depending on what roll-packed mattress you have ordered:
