Firstly, regarding the mattress. We are both very pleased with it, particularly as the previous mattress was a very well known and expensive memory foam one which had not only become uncomfortable but in warm to hot weather caused you to overheat. Our Drift mattress has solved both those issues and at a fantastic price. I am around 95kg and find it very comfortable. When we need a mattress for another bedroom it will definitely be a Drift one. Secondly, the service. This was excellent and a minor issue was resolved promptly and reasonably and my 7 yr old daughter appreciated the gift. 10 out of 10 to Drift Sleep.
