Is the Lakeridge worth buying used?

Only if the price is well below new and the mattress shows no sagging or stains. Used mattresses carry no warranty, so inspect the coils and cover in person before paying.

How does it compare with the current Costco Stearns & Foster models?

Newer Kirkland Stearns & Foster mattresses use similar coil counts and foam layers but add updated covers and sometimes a plush option. The Lakeridge is cushion-firm only.

What foundation does it need?

A rigid foundation or box spring rated for a king, plus a frame with center support. A flexible or sagging base will shorten the mattress's life.

Is it good for side sleepers?

The cushion-firm feel is on the firm side for many side sleepers. Lighter side sleepers may want a softer topper.

The mattress only. Foundation, frame and bedding are sold separately.

Costco clearance and warehouse markdowns were the lowest new prices. Used listings now set the floor, and prices drop when sellers need it gone.

Our take on the Kirkland Signature by Stearns & Foster Lakeridge King Mattress

The Kirkland Signature by Stearns & Foster Lakeridge is a 14.5-inch king innerspring mattress sold through Costco. It pairs Stearns & Foster's IntelliCoil HD pocketed coil system, with over 1,700 individually wrapped coils, with Indulge memory foam and high-density foam layers in a cushion-firm feel. A gel-infused center layer adds lumbar support, and the TENCEL Lyocell knit cover wicks moisture. It is a discontinued Costco model, so current stock is mostly used or clearance units rather than new retail.

Pros

Firm, supportive feel that holds up over years
Good edge support from the coil perimeter
Less motion transfer than traditional innersprings

Cons

Firm feel takes getting used to
Heavy and awkward to rotate
