After sleeping on a sleep number bed for 15 years I was nervous about buying a new mattress but after laying on the Serta brand my fears went out the window. Once I spoke to a salesman and was directed to the type of mattress I needed for being a side sleeper, it was a match made in heaven. The Visby Lake Plush is a great mattress and the quality of the stitching is incredible. I would recommend buying a Serta to any one who is looking for a great sleep experience.
