How soon can I sleep on the mattress once I get it?Updated 2 years ago

Great question! 

Once you have your mattresses unboxed and on your foundation, we suggest that you give it at least 30 minutes to 2 hours to expand before sleeping on it. 

The mattress will continue to expand over time and should be at its full size within 24 hours of unboxing, even with you sleeping on it!
