I needed a new mattress, but knew I was going to find it hard to decide which one to get, so I thought if it wasn't suitable for me, then my daughter & her fiance could have it for a bedroom in their new home. Well I couldn't believe how comfortable it was, despite my back problems. I now understand why you are happy to allow people to have a 100 day trail, because you are so confident about your product. Ordering & delivery were so efficient. There was a definite odour from the mattress, which was mentioned & by airing the room well, it soon subsided. Thank you for taking the stress out of researching about different types of mattresses.
