10. Video: Will it hold my mattress pad in place?
Yes, it will help hold the mattress pad in place. The Better Bedder® is put on an empty bed and then stays there "forever" as you put sheets on and off the bed. When you have a mattress pad that stays on the bed, the pad could be put on either before the Better Bedder® or after the Better Bedder®.
If you frequently wash your mattress pad, then you may choose to put the Better Bedder® on first and not tuck the pad under the mattress. If you don't wash the mattress pad frequently, then you may choose to put the mattress pad on first and tuck it under the mattress. Both the mattress pad and the Better Bedder® stay on the bed as you put sheets on and off the bed.
And yes, even with a mattress pad, all the bedding will stay snug!
