Hi there, The World Class collection was first released in 2010, and the Cypress Latex Plush Firm model came out sometime in the first couple of years after that. It was a quilted tight top with a medium-soft feel that contained a little bit (~3/4") of medium firmness Talalay latex near the top, together with a relatively thick layer of softer transition foam, and a somewhat forgiving pocket spring support unit underneath. It was discontinued around 10 years ago and is no longer available, but you can still see some information about it here: https://www.goodbed.com/mattress-model/simmons-beautyrest-world-class-cypress-latex-plush-firm/

Since we haven't compiled a formal list of the most equivalent options for this particular mattress (if we had, you would see them on the link above), the first place I would look is our mattress search tool, which lets you filter the universe of available mattresses by whatever criteria you want. Applied to the details I provided about the Cypress Latex Plush Firm, there are currently 14 models that are similar. You can see those here:

Narrowing this a bit further, the ones that stand out to me that are of at least comparable quality (in this case, these options are actually better quality) and are likely to feel most similar to the Cypress Latex Plush Firm, I would focus on these options from Serta Perfect Sleeper Pro and Nest Bedding:

1. https://www.goodbed.com/mattress-model/serta-perfect-sleeper-pro-dublin-medium/
2. https://www.goodbed.com/mattress-model/serta-perfect-sleeper-pro-kensington-medium/
3. https://www.goodbed.com/mattress-model/nest-bedding-hybrid-latex/
4. https://www.goodbed.com/mattress-model/nest-bedding-natural-latex-hybrid-plush/

I suspect the Nest options might be a slightly closer match to what you're looking for, but these are all pretty close in feel. You can see that more clearly in this side-by-side comparison: https://www.goodbed.com/compare/?mod=serta-perfect-sleeper-pro-dublin-medium&mod=serta-perfect-sleeper-pro-kensington-medium&mod=nest-bedding-hybrid-latex&mod=nest-bedding-natural-latex-hybrid-plush

The last thing I'd mention is that all of the models above can be purchased online no matter where you live. If you're only interested in purchasing from a local store, this type of mattress can be a bit harder to find, but you can check our local mattress search tool to see if any of the stores in your area carry this type of mattress: https://www.goodbed.com/mattress-brands/?surface-type=1&support-type=53&comfort-type=5

If the local search page guesses your location incorrectly, you can enter your correct zip code using the "Distance & Location" filter.

I hope that's helpful.
