What size mattress cover do I get if my mattress is in between you sizesUpdated 8 months ago
We recommend buying the larger-size mattress cover. It is best if the cover fits loosely. Having the cover bigger does not hurt its effectiveness. You are still completely protected. Also, If the cover fits snugly, the mattress may feel stiff, and the seams and zippers will be stressed.
You can tuck the excess material between the mattress and box springs.
Here is additional information on how to measure your mattress.
