I am a side and stomach sleeper. I had a memory foam mattress prior which was not comfortable to me at all. I needed an extra firm mattress and this Beautyrest Silver Extra Firm was just what I needed for a good night sleep. This mattress provides so much support I am sleeping better and not waking in the middle of the night trying to roll over like I was with my old mattress. I have woken in the morning well rested and NO BACK pain which is AMAZING! My husband also is sleeping better. We both are sleeping more soundly with no more restlessness at night. If you are looking for a firm mattress this is the ONE, look no further!
