This plush mattress was advertised as a medium in comfort level. It is actually pretty firm. I put a plush fiber mattress pad on top, which helped a lot, but will add a plush latex or memory foam topper before long. The bed is guaranteed 25 years and I can see why. The workmanship is very good, the bed is substantial, and I trust the Lucid brand, however, I would like it much better if it were softer. It may be truly a medium in comfort and that IS what I ordered. I think I have just gotten older and more achy, and have changed from preferring a firm bed to an ultra soft bed. Arthritis will change one's perception of comfort. If so, that's not the fault of the bed. Hence the 5 stars. Just be aware, I would not call it plush.
