Hi, we are looking at changing our mattress, and the choice is bewildering! We currently have a Sealy posturpedic pillowtop (it actually has a pillow on both sides, so can be turned over) on a divan base, which we bought in the USA 18 years ago! It is Dtill fine, but we are conscious that we should look at changing after all that time. Our concern is that we may spend a lot of money and end up with a less comfortable mattress! We both want pocket spring, not memory foam. We recently tried (in store) a Staples pure indulgence mattress in Bensons and loved the feel of it (firmness level 3). Based on your review, what is your equivalent mattress? And can we try it out anywhere? I can’t imagine spending hundreds of pounds on a mattress I have not even tried! Thanks in advance for any advice you can give us!
