Perfect Day iSeries


Perfect Day® iSeries® utilizes Serta’s new iSeries® technology combines our revolutionary Cool Action™ gel memory foam with our most advanced innerspring, the Duet™ Coil Individually Wrapped Coil-in-Coil support system. 25 years limited warranty.

Perfect Day® iSeries® models come in 2 different top/cover designs: flat tight knit cover (true hybrid version) or puffy quilted top cover. Flat tight knit cover models will feel similar to memory foam mattress, since memory foam will be closer to the top of the mattress. Quilted top cover models will feel similar to the standard innerspring mattresses. Each design comes in several softness options - extra fim, firm, plush firm, plush, firm pillow top, plush pillow top. Top of the line models will feature a combination of Cool Action™ gel memory foam and KoolComfort memory foam.

Some retailers have their "exclusive" collections with minor modification in type and thickness of padding layers. When comparing models always focus on coil type and coil amount, and also presence and thickness of premium materials - memory foam, gel foam, latex. Many retailers will have different names for the same mattress in this line, so you need to focus on an actual line not a single product.
