Price is a con for some people, because pillow top mattresses are generally more expensive than regular mattresses. However, if you are spending money on mattress pads for added comfort, it may be wise to invest in a pillow top with the softness already attached, as it may save money in the long run. Also, consider some regular mattresses are pricey as well and do not offer the added comfort.
Pillow top mattresses require sheets with deeper pockets, so if you are trading a traditional mattress for a pillow top, you will need to purchase new sheets. This can be a con because of the inconvenience, and a point to consider before switching to a pillow top.
Comfort is a pro. The pillow top is widely known for its comfort and for people who prefer a soft mattress, the pillow top is good choice. Those who toss and turn, don't get a good night's sleep or wake with an aching back may consider this type of mattress to help alleviate these problems.
This is a con if you have small children and allow them to sleep next to you for breastfeeding or other reasons, especially for infants under 1. The pillow top is soft, and a person's body sinks into the mattress. For an infant, this can result in accidental suffocation. For some, an infant sleeping with the parent on any type of mattress poses a suffocation risk. Parents should consider the dangers before buying a pillow top mattress.
One of the cons for the pillow top mattress is it is not made to flip. Flipping the mattress is supposed to help the mattress keep its shape and keep the internal stuffing evened out. If flipping is important, there are two-sided pillow tops that can and should be flipped to maintain the quality of the padding and keep the mattress comfortable.
