Put this on as soon as I received it. Suggest you follow directions and wait until it fills out, but Hubby was in a hurry and since it was king size, thought I better let him help me. We have Select Comfort bed - but is is an older one (with pillow top) This 3 inch mattress topper gave it a new life, I don't think we will ever need a new mattress!!!
