I've never suffered back problems before, but almost from the beginning this mattress had me waking up with a lower backache. It is really comfortable, and I tried to give it time, but now I'm at chiropracter and have heard that this type of mattress (latex foam) brings her lots of business because many (back sleeper) people need firmer support.
Date Purchased: winter, 2010/11 Price Paid: $0 Recommend: No
Very comfortable, my husband loves it and it agrees with his back!
As above, the Sultan Engenes was bad for my back, not enough support.
