Kirkland Signature (Stearns & Foster) Lakeridge 14.5″ can still make sense if you specifically want that brand, its retailer policy, or its lowest sale price. It is not our top buy-button recommendation. For most shoppers, we would compare it against Saatva Classic first, then use the cheaper options below if the budget is tighter.
Kirkland Signature (Stearns & Foster) Lakeridge 14.5″
7.8/10
- IntelliCoil HD coil-within-coil system delivers genuine Stearns & Foster construction quality
- Tencel and PrimaCool cover wicks moisture and runs noticeably cool
- PrecisionEdge perimeter support keeps the full sleep surface usable
- Costco's return policy is essentially unlimited in-store
- Queen pricing around $849-$1,099 is 30-40% below comparable retail S&F models
- Pillow Top version can develop body impressions for heavier sleepers within 12-18 months
- Runs firmer than the "medium" marketing suggests; some buyers add a topper
- Motion isolation is decent but weaker than all-foam competitors
- Requires a Costco membership ($65-$130/year); not sold direct
- No sleep trial window equivalent to online brands (return is in-store or by arrangement)
In our assessment, the Kirkland Lakeridge earns its place as one of the better-value hybrid mattresses sold through a retail club. The IntelliCoil HD construction is the same system Stearns & Foster uses in its pricier department-store line, and the Tencel cover keeps sleeping temperature reasonable for most people. The main watch-outs are the pillow-top durability concern and the slightly firmer-than-labeled feel, which led a meaningful share of reviewers to add a soft foam topper.
What the Kirkland Signature mattress is actually made of
The Kirkland Signature Lakeridge is manufactured by Stearns & Foster under a Costco private-label agreement. The construction runs from the surface down:
- PrimaCool cover with Tencel fiber: a moisture-wicking quilted fabric layer that keeps the sleeping surface cooler than standard polyester covers.
- Indulge Gel Memory Foam comfort layer: roughly 2 inches of proprietary S&F memory foam that conforms to body contours and distributes pressure around the lumbar and shoulder zones.
- Gel foam transition layers (soft + firm): additional foam strata that bridge the comfort layer to the coil core and prevent the "hammock" sinkage common in thinner hybrids.
- IntelliCoil HD support core (18.4 cm / approx. 7.25″): the hallmark of the Stearns & Foster line, a coil-within-coil (or "dual-stage pocketed") system that responds independently to each body zone. The inner coil manages initial compression; the outer coil provides firm base support.
- PrecisionEdge perimeter: reinforced border coils along all four sides so the usable sleep surface extends to the edge, useful for couples who share the full width.
- AirVent system (side vents): lateral ventilation channels in the coil layer that promote airflow and help dissipate heat that accumulates in the foam layers above.
The total profile is 14.5″ tall (Pillow Top version) or 14″ (Tight Top). Both sit on the firmer side in practice, with many reviewers describing the Pillow Top as "firm with a plush surface layer" rather than the "medium cushion firm" label.
Comfort and firmness: what to expect
Stearns & Foster markets the Lakeridge as medium or cushion firm, but in our experience with comparable S&F construction and in line with the weight of Costco customer feedback, the real-world feel lands closer to a true firm for most adults. The Pillow Top adds a surface softness that takes the edge off pressure points at the shoulder and hip, but the IntelliCoil HD system underneath is designed for support, not sink.
Averaged-sized back sleepers between 130-230 lbs will find the lumbar support straightforward and the sleeping position easy to maintain. Side sleepers in that same weight range can work with the Pillow Top version, particularly if they sleep with a quality pillow and keep shoulders aligned. Sleepers over 230 lbs often report the IntelliCoil core provides excellent support but the pillow-top layer compresses more quickly over time.
Stomach sleepers should approach cautiously. The Pillow Top's surface softness can allow the pelvis to dip into a slight anterior tilt for lighter-weight stomach sleepers, which increases lumbar pressure. The Tight Top version is firmer and a better structural fit for stomach sleeping, but it is less widely available through Costco at any given time.
Performance: cooling, motion isolation, and edge support
The Tencel-covered PrimaCool surface performs well for a hybrid in this price range. The AirVent system and the open coil core allow reasonable airflow, and in our testing of comparable S&F construction, surface temperatures stay meaningfully lower than what you get from a dense all-foam mattress. Hot sleepers will likely find the Kirkland Lakeridge acceptable, though it does not match the active cooling of gel-foam alternatives like the purpose-built cooling hybrids.
Motion isolation is the Lakeridge's biggest weakness relative to online mattress brands. The IntelliCoil HD system is individually pocketed, which helps, but the coil-within-coil geometry transmits more cross-bed movement than an all-foam or foam-heavy hybrid does. This is a standard trade-off for innerspring construction and is not specific to the Kirkland version.
Edge support is a genuine strength. The PrecisionEdge perimeter system keeps sinkage at the edges controlled. Both sitting on the edge when getting up in the morning and sleeping near the edge are comfortable, and the usable sleep surface extends close to the perimeter, which matters for couples who use the full width of the bed. See our motion isolation guide and medium-firm mattress roundup for comparison context.
Durability and the sagging question
The most consistent complaint across Costco reviews for the Lakeridge Pillow Top is premature body impressions. A meaningful minority of owners report that the pillow top develops permanent indentations within 12 to 18 months, particularly for sleepers over 200 lbs who sleep in the same position nightly. This is partly a function of the pillow-top construction: the fiber-fill and foam layers in the top panel compress with repeated use faster than the IntelliCoil core underneath degrades.
Stearns & Foster's 10-year limited warranty covers manufacturing defects including indentations of 1.5 inches or greater, but the standard warranty threshold is often just above what visible softening looks like in practice. If durability is a primary concern, the Tight Top version, with its lower-profile firm top, shows fewer complaints on this front. Rotating the mattress 180 degrees every three to six months also extends the pillow top's useful life.
For buyers who want long-term durability, the foam-over-coil build with a reinforced perimeter is fundamentally sound. Most owners report the IntelliCoil core itself holding up well past the warranty window.
The Costco value equation
Retail Stearns & Foster mattresses in comparable configurations start around $1,799 for a queen and run above $3,000 for premium models. The Kirkland Signature version sells in the $849 to $1,099 range for a queen depending on the current Costco promo, which represents a substantial saving for the same IntelliCoil HD construction. Factoring in an annual Costco membership ($65 to $130), the net saving over a directly comparable retail S&F remains significant for most buyers.
Costco's return policy is a meaningful added benefit. Unlike the 30-to-100-night sleep trial windows offered by online mattress brands, Costco's satisfaction guarantee allows returns without a fixed cutoff in most cases, which reduces the risk of being stuck with a mattress that turns out firmer than expected.
The trade-off is that you are buying a mattress you cannot easily compare side-by-side with online alternatives, and the Costco-only distribution means resale and trade-in options are limited. For context on policy comparison, see our Costco mattress return policy guide.
Sizing and price
| Size | Approx. price (Costco) | Notes |
|---|---|---|
| Twin XL | ~$599-$749 | Pillow Top available |
| Full | ~$699-$849 | Pillow Top available |
| Queen | ~$849-$1,099 | Most popular size; both versions available |
| King | ~$1,099-$1,349 | Very heavy (approx. 165 lbs); plan for two people for setup |
| California King | ~$1,099-$1,349 | Availability varies by warehouse and online stock |
Prices fluctuate with Costco's periodic "Costco Direct" promotional events, where bundles (mattress plus adjustable base, for example) can drop per-item pricing further. The mattress is not available through any other retailer, and prices are not typically negotiable in-warehouse.
Trial, shipping, and warranty
- Trial period: No fixed sleep trial. Costco's standard return policy applies, which allows returns without a set deadline in most cases, subject to local warehouse discretion and condition of the product.
- Shipping: Costco offers white-glove delivery with setup and removal of your old mattress for an additional fee, or in-warehouse pickup for the Pillow Top. Delivery timelines and availability vary by region.
- Warranty: 10-year limited warranty covering manufacturing defects and indentations of 1.5″ or greater. Claims go through Stearns & Foster directly; documentation requirements apply.
The Kirkland Signature by Stearns & Foster delivers genuine IntelliCoil HD construction at 30-40% below retail S&F pricing. It fits back and side sleepers in the 130-230 lb range who want a firm-leaning innerspring feel and value Costco's return flexibility. The main caveats are weaker motion isolation than foam alternatives and Pillow Top durability concerns for heavier sleepers.

Frequently asked questions
Is the Kirkland Signature mattress made by Stearns & Foster?
Yes. The Kirkland Signature Lakeridge is manufactured by Stearns & Foster (a Tempur Sealy International brand) under a private-label arrangement with Costco. The construction uses the same IntelliCoil HD coil system found in Stearns & Foster's retail line, at significantly lower pricing.
How firm is the Kirkland Signature mattress?
Despite the "medium / cushion firm" label, most owners describe the Lakeridge as feeling firm to quite firm in practice. The Pillow Top version adds a plush surface layer that softens the initial feel, but the IntelliCoil core underneath is built for support. If you typically sleep on a medium (5-6 out of 10) mattress and find it comfortable, expect to land closer to a 6.5-7 on the Kirkland.
Can you return a Kirkland Signature mattress to Costco?
Costco's general return policy has no fixed cutoff, and most members report being able to return mattresses they are not satisfied with, though warehouse discretion and product condition apply. This is not the same as a structured 100-night sleep trial, but it is meaningfully more flexible than most retailer policies. See our full Costco mattress return policy breakdown for details.
How does the Kirkland Signature compare to a standard Stearns & Foster mattress?
The core IntelliCoil HD construction is comparable to retail S&F models, but the Kirkland version strips out some of the premium finishing and fabric treatments found in department-store configurations. The result is a meaningfully lower price for largely the same mechanical support. For buyers who primarily value the IntelliCoil system and are not focused on top-panel materials, the value trade-off is clear.
Is the Kirkland Signature good for back pain?
The IntelliCoil HD base provides consistent lumbar support, and most back sleepers in the average-weight range report adequate spinal alignment. The gel memory foam comfort layer adds pressure relief at the lumbar and hip. That said, the firmness level can be too aggressive for some back pain sufferers who need a softer pressure-relief layer. If you have active lower back pain and prefer a medium-soft feel, consider the AS3 above or check our back pain mattress guide for more options.
What mattresses are similar to the Kirkland Signature but available without a Costco membership?
Each trades the Kirkland's Costco pricing advantage for a proper sleep trial, direct-from-brand support, and in some cases stronger motion isolation.
