The 13" high Novaform Rhythm
has three layers. Support and stability are provided by the 7" base of polyurethane foam. The 4" center layer of DuraTex
foam is described by Costco
as "dynamically responsive" to allow the sleeper to move easily (I did not find DuraTex
by name on the Sleep Innovations
website, but the description of their Luratex
foam is very similar; they say it has an elastic resiliency like that of latex
). The 2" top layer is gel-infused memory foam. The gel is a heat sink, drawing heat away from the sleeping surface. Its open-cell structure allows air to circulate for further cooling.
is the firmest of the Costco Novaform
models, with a firmness level of Very Firm (3 on a scale of 10). Its contouring level is only 2/5, and it is described as "responsive."
The matelassť cover fabric has a spiral quilted design and meets the federal flammability standards for bedding (16 CFR Part1633).
The Costco Novaform 13" Rhythm Memory Foam Mattress
carries the Sleep Innovations
20-year manufacturer's warranty. It is compressed and packaged for ease of shipping and delivery.
