8. Video: Why should I measure my mattress?

There are many variations to standard mattress sizes. You may think you have a standard size mattress, but you will get our Better Bedder and your sheets won't fit tight because your mattress is several inches smaller than a standard and you never knew it. Our Better Bedder will work if your mattress is within an inch or two of these measurements:

Twin 38" x 75"
Twin XL 38" x 80"
Full 54" x 75"
Full XL 54" x 80" (See Custom RV)
Queen 60" x 80"
Short Queen 60" x 75" (See Custom RV)
Short King 72" x 75"
King 76" x 80"
Cal King 72" x 84" 
Split King (Twin) two 38" x 75"
Split King (Twin XL) two 38" x 80"
Split King (Cal King) two 36" x 84"


The Better Bedder® should be tightly gripping the corners of your mattress but should be loose along the sides. Ideally, the Better Bedder® should sit at least two inches below the top of the mattress. If you have a removable mattress topper, the Better Bedder® should sit two inches below it. If you have a sturdy permanent topper, the Better Bedder should sit just below the topper.

The Better Bedder® fits all mattress heights. If your mattress is 17 inches in height or less, you’ll tuck the excess of the Better Bedder® under your mattress.  If your mattress is over 17 inches in height, you simply won’t have any excess Better Bedder® to tuck under your mattress. If you have a thin mattress, it needs to be firm for the Better Bedder to work. If your mattress is under 7 inches, then it must be very sturdy for the Better Bedder to work. If your mattress is soft and flimsy, the Better Bedder won’t grip the corners of your mattress like it should. Instead, your mattress may bend from the Better Bedder.

We also offer a custom-made Better Bedder® tailored to your precise dimensions. So even if your mattress is not a standard size, there is a Better Bedder® for you.
