The name My Side pictures the concept of these mattresses by Kingsdown. A branch-off from the Sleep to Live Collection, My Side Collection mattresses are customized for the customer by the computerized bedMATCH diagnostic system. BedMATCH uses "18 statistical measurements and over 1,000 calculations" to match customers to mattresses and foundations meeting their needs.
With the My Side Collection, this goes a step further, customizing one side of the bed for one sleeping partner and the other side for the other person (a concept known elsewhere as "dual comfort"). Retailers listing Kingsdown My Side mattresses online list sizes down to Twin (Single in Australia). However, Twin size has to be seen as an exception, since formatting the two sides separately is obviously impractical. The dual comfort configuration is barely manageable in Full (Double) size, and is better suited for Queen size and up.
There are a few notable differences between My Side and Sleep to Live mattresses. Those in the Sleep to Live Collection are dual innerspring mattresses. The primary innerspring has steel pocket coils, and the secondary innerspring has foam springs (foam coils). My Side models may be innerspring or foam core mattresses. the foam core models have a 6½" foam support core (one retailers lists only the foam core models). Mattresses in both collections are vertically zoned, with each layer down responding progressively.
All My Side mattresses feature gel. This is reflected by the G in the series' names. They have a gel pad which is contour-cut for tailored support distribution, especially in the lumbar region.
Another common feature is the Cool Wave Foam. This is ventilated gel-infused memory foam with a sculpted surface to foster horizontal airflow. The simplest My Side mattresses (3G) have the gel and the support core with the Cool Wave and the quilted cover and pillow top.
Also, they all feature Kingsdown's foam encasement, Full Body Surround® Edge Support with Airflow.
Some model series feature memory foam, and some feature latex, which means the My Side Collection includes innerspring mattresses, memory foam mattresses and latex mattresses. No doubt, some may be classified as hybrid mattresses.
Some of the mattresses in the Kingsdown My Side Collection are two-sided (flippable), some are one-sided (no-flip).
An upholstered wood base is the default foundation for My Side mattresses. But they are also compatible with platform beds, European wood slats (if the slats are close enough), adjustable beds (a.k.a. "motion bases"), and advanced-design box springs (such as Leggett & Platt's torsion bar Semi-Flex).
Kingsdown does not list a warranty period for the My Side Collection. However, one retailers lists different warranty periods for different models, ranging from 10 to 25 years.
