Measuring Mattress Depth for Dust Mite Encasings
Our dust mite encasings come in two depths: 9" deep and 15" deep. If your mattress is 10-15" deep you will use a 15" encasing. Queen and King
sizes are also available in an 18" deep version. Any extra fabric can be easily and harmlessly tucked in-between the mattress and box spring.
How to Measure Mattress Depth:
- Remove comforter, blankets, sheets, and mattress pad
- Use a tape measure or ruler to measure mattress depth from seam to seam.
- If the mattress has a sewn in pillow top, measure in several places to get an accurate measurement.
How to Measure Mattress and Box Spring Size:
- Remove comforter, blankets, sheets, and mattress pad
- Measure the length and width of the mattress with a tape measure or yard stick.
