We recommend opening your Leesa mattress within 30 days of delivery.
While it is safe for your mattress to stay packaged for longer, leaving it in the box for an extended amount of time may not allow the mattress to fully decompress, altering the way the foams were intended to feel and perform.
Also, your 100 night trial will begin on the day your mattress arrives, so you won’t want to keep it boxed up for too long!
