Costco Novaform 13" Rhythm
Memory Foam Mattress

Of the eight Novaform mattresses listed by CostcoWholesale Corporation, 13" Rhythm is the second. These memory foam mattresses are designed and made for Costco by Sleep Innovations and are available both in the stores and online. Rhythm and Encore constitute Novaform's Acclaim collection.

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.

Rhythm 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.
