We have created the Lori Mattress, which will be the perfect fit for the Lori Bed! The Lori Mattress is the first mattress designed from scratch to be comfortable and long-lasting when stored in a Murphy bed. The support throughout the mattress, as well as the edge support, ensures that it will not sag or slump when being stored on its side.

If you would like to use a different mattress, that is totally fine as well. Just be sure that the mattress is 12" thick or less and is not too heavy. We recommend a max of 80lbs for the Queen and 50lbs for the Twin, as you and a partner will be using your own strength to lift and lower.
