I have had this mattress 2 weeks now. Was a little too firm for me at first but is adapting. Is 5cm higher than my last mattress which I like. It gives the bed a nice height when sitting on (I probably should mention im only 5ft tall, but this is perfect for me). I also bought the Carshalton small double bed frame. The 2 go well together. If the firmness subsides a little more I would rate it with 5 stars.
