These sheets have deep enough pockets to fit a thicker mattress with no problems. Additionally, the 24 ounce weight of the fabric is much higher in quality. If you are dealing with a thicker mattress, or you're just tired of poorly-made, low-grade hospital sheets, definitely buy these--they are worth the extra expenditure! These sheets fit very well and stay in position. They wash well and feel nice on skin. The fabric feels like a HEAVY weight T-shirt in thickness. White is a good easy to wash color (if you like to use bleach) and it goes with ANY color or design of top sheet that you would buy. Comfort, durability and value --- good combination. Machine wash on cold, tumble dry low. No ironing needed
