Sleepy's use independent contractors for delivery services to our customers and during this time we want to support these small business owners and our customers to ensure safety for all. This may mean some interruptions to our normal delivery service and Free Old Mattress Removal which will be based on advice obtained from the Australian Government and the precautionary measures our delivery contractors determine necessary. If you are purchasing in one of our Sleepy’s showrooms or online, our staff will confirm the current status and keep you updated until your order has been delivered. If you are unable to accept the delivery due to illness or quarantine, you can arrange an alternative delivery time with the store. We are committed to continuing Sleepy’s amazing customer experience from the start of your mattress selection through to post purchase, delivery and beyond.
