Stearns & Foster® Estate Collection is an upgraded line of its innerspring mattresses offering Intellicoil iD™ support - double tempered, individually wrapped titanium coil-in-coil design innerspring for more durable and less disturbing sleeping. Tricky part is figuring out the coil count for this type of innerspring, you would need to multiply each coil by 2, where smaller coils is inside of the bigger coil, but we think both coils should account for one. S&F markets these springs as made from Titanium Alloy, but they are actually steel spring with a miniscule amount of titanium. All models have foam encasement all around the mattress for sturdy edge support. There are handles on both sides of the mattress for easier manipulation. More expensive models will feature a layer of memory foam or a layer of Smart Latex. 10 year limited warranty.

Estate Collection models come in several softness options: Firm, Ultra Firm, Plush, Plush Pillow Top, Firm 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.
