A folding mattress — also called a tri-fold mattress — is a foam mattress divided into three equal sections that fold onto each other for compact storage and unfold flat for sleeping.

The tri-fold design makes folding mattresses a practical alternative to permanent guest beds in small spaces. The Lazyzizi folding mattress is available in a 4-inch and 6-inch profile: the 4-inch folds into a package roughly the size of a large carry-on, while the 6-inch folds slightly bulkier but includes a 1.5-inch memory foam layer over a 4.5-inch support base — enough structure to sleep closer to a standard mattress rather than a camping pad.

  • Lazyzizi folding mattress comes in two profiles: 4-inch and 6-inch thickness options.
  • The 6-inch model is built with 1.5 inches of memory foam over 4.5 inches of support base foam.
  • Both folding mattress profiles ship vacuum-packed and require 48–72 hours to fully expand.
  • Lazyzizi folding mattress foam is CertiPUR-US certified; the bamboo cover is OEKO-TEX tested.
  • The bamboo cover on the Lazyzizi folding mattress zips off and is machine washable.
