I got this first in a king size to add a plus feel to our good mattress. It made our bed heavenly. So I decided to get it in a full for our guest bed as well. However, that mattress is not comfortable and even with this pad it's still uncomfortable. So if you have a good mattress and just want an extra bump up in softness, this is great. If you have an uncomfortable mattress already, this isn't going to help much.
