Vi Spring Shetland Superb mattress questions

Hi John and Ryan, I left a comment on your site a couple of weeks ago, but now can't find it - so I thought I would email you instead. We spoke several times last year about soft mattresses. I am 5 foot 2, seven stone, and have arthritic hips. I am naturally a side-sleeper, but can't sleep on my side as my Vi-Spring medium mattress is too hard, despite having a goose-feather topper on it, with a memory foam topper on top of that (yes, I need a ladder to get into bed). I've been looking at your 6-pocket Laygel hybrids, but am not sure that they would feel soft to me if they feel soft/medium to people who are two stone heavier than I am. When we last spoke, you said you may well be producing something really soft in the future, so I was wondering if you have meanwhile developed something that might be suitable?

The one mattress I really liked when I tried it was a very well-used Vi-Spring Shetland Superb on display in a store in York - but when I tried another, less well used, one in ASTB, it felt much harder and less comfortable. Any advice would be very welcome indeed!

Kind regards, Helena
