Posturepedic® Classic Series is an of the most popular and well recognized mattress lines around. It has been in production for decades with updates periodically every 2-3 years. The traditional Posturepedic® Classic Coil innerspring provides great support, but it is rather bouncy, since the spring are connected. Sealy markets these springs as made out of Titanium, but they are actually standard steel spring with a miniscule amount of titanium. Some of the models offer CoreSupport™ Center as an extra support in the central third of the mattress. Another main difference among different models is addition of memory foam layer. The foundation used called StayRight Foundation has rubberized top to prevent mattress from sliding off. There are handles on both sides of the mattress for easier manipulation.
Classic Series models come in several softness options: Firm, Cushion Firm, Plush, Pillow Top these will vary in type and thickness of the comfort layers
Some retailers have their "exclusive" collections with minor modification in type and thickness of padding layers. When comparing models always focus on coil type and coil amount, and also presence and thickness of premium materials - memory foam, gel foam, latex. Many retailers will have different names for the same mattress in this line, so you need to focus on an actual line not a single product.

The best deals on some Sealy models are available in Costco warehouses or on Costco.com website. If you don't have a warehouse membership you can try to use their advertised prices for a price match with your local store.
