Back be Nimble

Back be Nimble offers two models of their Nimblepedic™ memory foam mattresses, the 8-inch high Traditional Nimblepedic and the 11-inch Deluxe Nimblepedic.
The Traditional Nimblepedic has a 3⅝-inch top layer of 4-lb. density memory foam with a slightly lower ILD than Tempur-Pedic and a bit less on the mattress cost. The base is 4” of a high resilient 32-ILD foam with edge support. As mentioned previously, we do not feel that edge support is necessary in a well-built memory foam mattress. The cutaway view shows a ⅜” poly-foam air barrier. This would stop any airflow to the lower layer, which limits cooling the mattress, even with open-cell memory foam.
The memory foam layer on top of the Deluxe Nimblepedic is 4” high with 5.7-lb. density. The ILD is not given by number, but is called “Plush Touch Advantage.” Back Be Nimble says this lower ILD then Tempur-Pedic gives the mattress a feel that is “softer” and “luxurious.” Beneath the visco memory foam is a 3” later of latex. It has the same support core as the Traditional Nimblepedic. Since the top layer is ⅜” higher than in the Traditional model, it appears that it does not have the air barrier. This would allow the memory foam to breath into the latex, providing some cooling. But without positive horizontal airflow, it would not have the same degree of cooling as a Tri-Pedic mattress with the Airflow Transfer System option,
The cover fabric of both Nimblepedic models is a silk blend velour labeled as breathable and cooling. Back Be Nimble offers a 60-day trial period and a 20-year limited warranty.
