Sleep Number Split Top King Sheets

Who Might Not Want A Sleep Number

What Makes Sleep Number® Sheets Better?
  • People who love memory foam Depending on what is available, there are one possibly two Sleep Number models that offer a comfort layer made with memory foam. Those who love the feel of classic memory foam will be limited on Sleep Number beds, which are at their core adjustable air beds.
  • Couples who like to sleep close together One of the biggest complaints from couples is that a sagging/division is created in between the dual air chambers on the bed. Couples who like to sleep close or cuddle in the center of the bed feel as those they are sinking into the middle of the bed.

Construction And Materials Comparison

The construction of a mattress is of central importance to its feel, performance, and durability. The construction includes both the design of its layers and the actual materials used in those layers.

In general, a mattress can be understood as having two main sections:

  • The comfort system is the top part and offers the most immediate effect on feel. It is normally made of polyfoam, memory foam, latex, wool, cotton, and/or polyester.
  • The support core is the bottom part of the mattress. It affects the mattress feel and the performance of the comfort system. The support core also helps prevent against excessive sagging in the mattress. It can be made with polyfoam, latex, innerspring coils, or air chambers.

Both the comfort system and support core can be made up of one or more layers that can be the same or different materials. Quality components in each and every layer will help protect against a weak link that drags down the overall mattress performance.

The following sections give an overview of the construction and materials in the Tempur-Pedic and Sleep Number beds. While we know the basics about what goes into them, neither company discloses all the specifications of their mattresses, which can at times make it difficult to fully compare their models.

Can I Use Regular Sheets On An Adjustable Bed

You can, but then youd have to wrestle your sheets every time you place your adjustable bed in a different position. Regular sheets are designed for beds that remain flat, which is not something adjustable beds are for.

Using regular sheets on an adjustable base would cause the sheets to wrinkle and bulk up in the middle and slip off at the corners, making you lose sleep over it. That is why there are special sheets designed for adjustable beds.

In the hunt to find one of the best sheets for adjustable beds, otherwise known as split kings, you’ll have a lot of choices. But, as you already know, any old king-sized sheets won’t work on an adjustable bed. You’ll need sheets designed to fit each side of your mattress separately, giving you the flexibility to adjust the bed to suit your needs.

Consider first if you need a split king or a split California king. While most sheets for adjustable beds come in split king, there are fewer options if you need ones for a California-style bed. Then the name of the game with sheets is fabric and how it’s constructed. You can learn a lot about a set of sheets simply by looking at the fabric. And, as I combed through sheets available in split king sizes, I found that most options are made of one of three fabric styles. Here’s your guide.
