Tight Corners? No Problem.


You may want to change the layout of your room, relocate to another room, or even move to a new home. Because each piece of a split king is half the size of a traditional king mattress, you can maximize maneuverability through doorways, around tight corners, or even up and down the stairs.

  • Under normal conditions, the beds will not separate — particularly if they are used within a piece of furniture that surrounds the bed to help define the space.

    Even without a piece of furniture, it's rare that the beds will separate as the weight of the bases and the mattresses will require a decent amount of force to move. Additionally, one of the benefits of TEMPUR® material is that it provides a great edge-to-edge sleeping surface that will minimize any feeling of the “split” as long as the mattresses are the same height. If you choose to customize one side or the other, there will be a feel difference when you move from one side of the bed to the other.

  • If the mattresses you choose for your custom Split King/CA King are of different heights, our Sleep Experts can help you understand how our adjustable bases may be able to help offset differences in mattress height. You can speak to a Sleep Expert by calling (888) 811-5053.

  • All Tempur-Pedic beds have a model identifier i.e. Cloud, Luxe, Adapt, or ProAdapt. As long as you choose a mattress with the same model identifier, the mattress will be manufactured to have the same profile height.  

    For example:

    • TEMPUR-Cloud® has a mattress height of 10"
    • TEMPUR-Adapt® Medium and TEMPUR-Adapt® Medium Hybrid have the same 11” height
    • TEMPUR-PRObreeze° and TEMPUR-ProAdapt° have the same 12” height
    • TEMPUR-LuxeAdapt® and TEMPUR-LUXEbreeze° have the same 13” height

  • A split king allows for two people to have their own sleep space that is customized to their wants and needs.

    Each sleeper can have a mattress that's their ideal feel without compromising.

    Plus, with an adjustable base, you can individualize your sleeping position by elevating your head and/or legs separate from your bed partner. This can also help with snoring and make reading, watching TV, or working in bed easier—separately or together.

  • The mattress edges are rounded therefore there may be a slight gap, but most owners do not feel it or have issues with it.  

    Additionally, one of the benefits of TEMPUR® material is that it provides a great edge-to-edge sleeping surface that will minimize any feeling of the “split” in the mattress as long as the mattresses are the same on both sides (i.e. both are TEMPUR-ProAdapt® Medium). If you choose to customize one side or the other, there will be a feel difference when you move from one side of the bed to the other.

  • Yes, all of our bases can be programmed to work independently. Each person would have his or her own remote allowing to change positions independently.
