After returning home from a holiday where we slept in a number of quality hotel beds, we realised that we needed to replace our own (relatively new) mattress with something firmer. Using the "calculator" on the Sealey website we picked this high-end model and it was a very good decision.We have both slept more soundly than we have for years, my snoring has decreased, and any niggling back pain after a day gardening is gone by the following morning. It isn't a miracle device - just a very comfortable mattress that provides excellent support.

Best mattress I’ve ever purchased! I’ve had this mattress for 5 months now and it is firm, yet soft and supportive. It is the best feeling getting into bed every night! Buy it, you won’t be disappointed!

This is amazingly comfortable. I haven't slept this well in years. Very highly recommend.
good queen size mattress, however, it is deep I needed to get/buy deeper walled 50cm fitted sheets and a new super king donna and a couple of donna covers, very happy with mattress, sleeping so, so much better.
Lovely comfortable mattress, like sleeping in a cloud. Nice quality damask material, good solid mattress expecting to get many years use out of it. Happy with my purchase so far.
Very happy with the mattress. Paul was very helpful in selecting the mattress unfortunately when I went back to pay the lady that processed it was terrible it took over an hour
The best of the best mattress - great discount - prompt delivery. Very pleased.
Bought this bed for my mum. Needless to say she loves it. The best part is I bought it in sale. #winning
This is the second Crown Jewel Posturepedic mattress we’ve bought from Myer. So, we’ve put our money where our mouth is in terms of telling friends just how good Posturepedic mattresses are. Simply it’s the best bed we’ve ever had!
Medium firm still way too firm. Were talked in to this range by the Myer salesperson. Not comfortable withis purchase.
