Beautyrest Silver BRS900 Medium matress is by far the very best mattress that I have ever had!! I have been married a long time and for the last five my husband and I slept in separate beds. Now we are able to sleep together again. This mattress doesn't creak or squeak at night. I can barely feel my husbands movement when he  tosses and turns. I am amazed at the high quality of the mattress itself. It is firm yet it still contours to your body. It is easy to get in and out of bed off of the mattress. I am truly amazed at how good this mattress truly is. I will never buy any other brand. Bravo!!!!!!!!!!!!!!! Thank you for creating the best mattress I have ever had!!!!
