Origins Pocket 1000/1500 vs Hypnos Premier Inn Mattress

Hi, I was looking how your Origins 1000 or 1500 would compare to the Hypnos Premier Inn Mattress that offer via the hotel for sale to the public, price wise there is not much in it with all of them inside the 400-500 mark for a double.
I currently have a Sleepeezee 800 pocket sprung which is about 5 years old, I am for my sins a stomach sleeper and feel like its starting to droop in the middle as I find myself putting my hands under my hips to bridge the gap in the night, I am about 85kg and the only person in the bed.
