Sleep Number beds are popular among those seeking adjustable firmness options, but their adjustable bases are only available for Queen-size mattresses and above, and they come at a high price. This has led many to consider pairing a third-party adjustable base with their Sleep Number mattress. Sleep Number bases are designed to work with any mattress suitable for an adjustable base, and some users have successfully used their Sleep Number bases with non-Sleep Number mattresses. However, a traditional box spring won't work with a Sleep Number mattress, and the slats on the bed frame should be no more than 2 inches apart.

Traditional box springs won't work with Sleep Number mattresses
Sleep Number mattresses are designed to work with adjustable bases, and the company offers its own adjustable bed frames. However, these adjustable bed frames are only available for Queen-size mattresses and above. Sleep Number bases are also quite expensive, so some customers opt for third-party adjustable bases.
It is important to note that traditional box springs will not work with Sleep Number mattresses. If you plan to use a Sleep Number mattress with a third-party base, there are a few things to keep in mind. First, ensure that the slats on your bed frame are no more than 2 inches apart. It is also recommended to place a bunkie board on top of the slats to create a durable, flat surface to support your Sleep Number mattress properly.
The Sleep Number FlexFit base is designed to fit inside most standard furniture, with the exception of platform furniture or furniture with under-bed storage. The base has seven adjustable height settings, ranging from 13.75" to 18.25" from the floor to the top of the base. The weight limit for the FlexFit base is 600 lbs per side.
When attaching a headboard to your Sleep Number base, you will need to use headboard brackets. If you have a narrow staircase, narrow entry to your home, or bedroom, Sleep Number recommends choosing a split queen integrated base over one solid piece.
In summary, while traditional box springs will not work with Sleep Number mattresses, there are several options for adjustable bases that can be used with these mattresses, including Sleep Number's own bases and third-party alternatives. It is important to carefully consider the measurements and specifications of your furniture and mattress to ensure a proper fit.
