What kind of sheets do I need for my Beautyrest mattress?
The style of sheets you use for your mattress is completely up to you, but for the sizing, you want to look specifically at the pocket depth of the sheet set.
Most standard-size sheet sets will have a pocket depth to accommodate mattresses up to 14 inches in height.
Deep pocket sheets will fit mattresses up to 15 inches in height, while extra deep pocket sheets will fit mattresses anywhere from 16-22 inches in height. Bedsheet measurements may vary by manufacturer, so be sure to check the pocket depth measurement on the sheet packaging.
Keep in mind if you use any protectors or toppers that increase the height of the mattress, deeper-pocketed sheets may need to be used.
