Hi pattycake,
Thanks once again for sharing your comments.
Just for reference and for the sake of others that may be reading this … there are many coil systems that use innersprings with a higher gauge than 13 that would be suitable for those that are over 200 lbs. I would be very cautious using wire gauge (or coil count) as a way to determine the quality, durability, or value of a mattress because the foam layers above the innerspring are usually the weakest link in a mattress, not the innerspring itself, and the gauge of the wire is only one of many variables that determines how a particular innerspring will feel and perform inside a specific mattress design and can be more misleading than helpful. The total amount of steel in an innerspring would probably be a much more important spec that could be used to compare innersprings (although this would also be somewhat misleading) but unfortunately this isn’t a spec that mattress companies normally provide. There is more about the different types of innersprings in this article and in post #10 here.
