I am interested in purchasing a Simmons world class plush firm Paris mattress from sleep train. I was doing my research online about it and came across people saying that the spring Simmons use aren't tempered. Is this true? If so, should I be concerned? I would like to know how this would affect the life and quality of the mattress. Thanks for any feedback.

Simmons Beautyrest springs are carbon tempered.

I don't believe that carbon is a form of tempering. Tempering is when you heat the wire up to about 450 degrees through an oven or electric shocks. Once this is done, you have less of a set in the coil. Pocket coils can be tempered electrically before they are put into the pocket. The last I had heard Simmons did not use this procedure to manufacture their pocketed coil. In defense though, they will put a larger coil into the pocket and compress it down, so that over time it will not show much of a set, however, it will start to get softer. I don't know if it is still true but back in the old days, Simmons used a higher carbon wire then their competeitors because they did not heat treat.

The additional carbon content is called "carbon tempering" or "high carbon tempered".

The process eliminates the need for heat tempering.

Unless you're very light weight, Simmons springs are likely to break in (if not 'down) very quickly, as they are made from a thin gauge wire. Personally I'd avoid Simmons, but maybe I'm wrong. If you don't weigh a lot then they might be okay for you. Or if you don't mind replacing them in a year or two if they get too non-supportive... As to the warranty, forget it. Most mattress warranties are useless, in practical terms. They send a guy out to your house, he says it's only dipping 1.25" so even though it it killing your back there is nothing "wrong" with the mattress and your warranty does not cover it.  A 1.25" dip is HUGE!

Simmons does not have any higher warranty claim rate than the other major manufacturers.

Simmons plush and pillowtops are good choices if you and your partner are both under about 220lbs. The Simmons firm is a good choice if you like the individual coil feel but are over these numbers. The plush and pillowtops are 15.25ga. The firm is 13ga.

Currently myself and my partner have a combined weight of about 260 lbs.  Is this to much for the Simmons springs to handle?  If so, any suggestions on what I should be looking for in terms of spring quality to support that weight?  Brands/models?

That should be fine for either the 15.25ga or the 13ga versions.
