Good afternoon,
Looks like one is gel foam and the other has latex. The latex mattress is pricier…more expensive materials.

Product Details for the S&F Elsie Luxury Plush Firm Ultra Pillow Top: An ideal choice for stomach sleepers, this luxury bed features a dreamy blend of Ultra Soft and HyperSoft® foams, plus the Indulge Quilt™, which all helps to relieve tension and cradle every curve & contour of your body. The addition of ClimaSense™ Gel Memory Foam guarantees temperature control and a cool sleep.

Product Details for the Estate Chasity: Cashmere infused cover that feels splendidly soft to the touch. Full layer of Latex that provides pressure relieving comfort through rich conformance or gentle support. Specialty formulated foams that are pre-compressed to ensure consistent long lasting comfort. Exclusive Indulge quilt which combines deluxe fibers with tension-relieving foams to cradle your body in indulgent comfort. Individually wrapped titanium alloy Intellicoil iD features a unique coil-in-coil design

These 2 beds should have very different feels. Stearns and Foster is a well-known brand. I've sold it in the past and haven't been terribly impressed with the value. Other brands you might consider: Aireloom, Naturepedic, FXI, Magniflex…they tend to be more eco-friendly. Thanks.

Hello -- it looks like the Cayla model at Macy's would be equivalent to the Chasity from Sears. These are both part of the Stearns & Foster Estate series.
