The 30-Second Verdict: Quick Summary
Worth a look if you already shop at Costco. Three outside sites scored a Lakeridge: NapLab gave 8.08 Overall Score, RTINGS gave 7.7, and Sleepopolis gave 4.5 / 5. Each site uses its own scale, so we do not add them up. A Queen Pillow Top costs $999.99, and the Tight Top costs $949.99.
Ask two things before you buy: how long you have to return it, and whether your size is in stock. Costco gives no trial length.

Key Strengths
Two clear choices. The Pillow Top is Medium and the Tight Top is Firm, so the pick comes down to feel.
Three outside test sites. NapLab, RTINGS and Sleepopolis each scored a Lakeridge and name the bed they tested.
Setup can be included. Costco's page lists White Glove delivery; room of choice, setup and haul away.
The warranty is stated. Costco lists a 10 year warranty.
Good to Know
No trial length is published. Costco's page lists this: Risk-free 100% satisfaction guarantee; refund of purchase price. It gives no number of days. NapLab lists Trial 365 nights, so get the return window confirmed by Costco before you rely on it.
Coil count and foam density are not published. Costco names its parts but gives no numbers, so you cannot compare them with rival beds.
Prices and stock change. The Pillow Top's page showed it out of stock when we read it, so check the listing before you plan a purchase.
Three things decide this page: how the Pillow Top and Tight Top differ, what outside testers found, and what Costco's return promise covers. The return promise has no day count.
Outside review scores
Review sites checked: NapLab, RTINGS and Sleepopolis. Their scores: 8.08 (NapLab), 7.7 (RTINGS), 4.5 / 5 (Sleepopolis). Model they tested: 14.5-inch hybrid, Medium firmness. Each site tests in its own way, so read each row on its own.
For Costco members who want a medium coil bed, yes. The outside scores are decent, and a Queen costs $999.99. Confirm the return window first, since Costco does not print one.
Fiberglass-Free Yes
Fiberglass-Free
NapLab lists the bed as fiberglass free. Costco does not say so on the pages we read.
reinforced edge support coils
pocketed coil support system
NapLab describes reinforced edge coils, which help if you sit on the edge of the bed.
Trial 365 nights
Shipping and returns are free
This is NapLab's figure. Costco's own page gives no day count, so the trial chapter explains the gap.
When Kirkland Signature makes sense
You are already a Costco member: you can use the store's return process, described in the trial chapter.
You sleep best on a medium bed: the Pillow Top is Medium and 14.5 in. tall.
You want a firmer feel: the Tight Top is Firm, with a price change of -$50.
When Another Mattress May Suit You Better
You want a written trial length: ask Costco for it before buying, since none is published.
You compare coil counts and foam density: Costco gives neither, so a maker that lists them is easier to compare.

Reading the scores
Why we don't average the scores
Each site tests its own way, on its own scale. We show each score next to the bed it tested and never blend them into one number. NapLab tested a 14.5 thick high-profile hybrid, RTINGS tested the Pillow Top Lakeridge, Medium firmness, and Sleepopolis tested a Medium-Firm 7/10 bed.
Use the dates and sources shown with each result. Prices, models and policies can change.
Chapter 02
Comfort and firmness: which mattress fits you
Why this matters to you: Feel words differ between brands, so your own body is the best test. Costco gives no fit chart by body weight for these beds.
Costco lists no weight ranges for this line. The guide below uses Costco's own feel labels, and your sleep position sets which one to try first.

Neck: on your side, your nose should line up with the middle of your chest, not tip up or down.
Shoulders: your bottom shoulder should sink in. Tingling or a numb arm means the bed is too firm for you.
Lower back: on your back, slide a flat hand under your waist. A big gap means too firm; no room at all can mean too soft.
Hips: ask someone to look from the side. Hips lower than shoulders means the bed is too soft for you.

Compare the mattresses
Why this matters to you: The two Lakeridge beds share a build but differ in feel, height and price. Pick the feel first, then look at the price gap.
The table puts both beds side by side. Both are listed as innersprings with memory foam on top.
Costco sells two Kirkland Signature mattresses made with Stearns & Foster. The choice is mostly feel: Medium for the Pillow Top, Firm for the Tight Top. The price chapter has the cost of each.

Mattress prices and value
Why this matters to you: Both beds sit close in price. The Tight Top's Queen price change versus the Pillow Top is -$50, so feel should drive the choice.
Prices below are what the Costco pages showed when we read them. Only the Queen has a price we checked, so other sizes say not yet researched.
A Queen Pillow Top costs $999.99, and a Queen Tight Top costs $949.99. Costco shows no list price, so we cannot say how much any sale saves.

Chapter 05
How well do the mattresses hold up?
Why this matters to you: A mattress is a long buy. Costco gives no lifespan and no durability test, so outside reviews are the best guide.
Costco gives no lifespan in years. The outside sites we read give scores, not a lifespan, so treat any age estimate as unproven.
RTINGS lists longevity among the things it tests, but we hold no longevity score. Press on the edges and the middle of the bed in a store, and ask about the warranty's sag rule.
What to watch for, and when:
Right after delivery: check the bed for damage before the crew leaves.
In the first weeks: sleep on it as you normally would. If it feels wrong, start a return while the option is fresh.
Later on: note any dip in the surface, and keep your receipt for the warranty.

Company History & Model Evolution
The story of Costco and its Kirkland Signature name, up to the Lakeridge mattresses sold today.
Kirkland Signature is Costco's own label, so the mattress carries the store's name, not a mattress maker's.

Each milestone comes from the brand's own pages, government and court records, or named news reports, each with the date we checked it. Factory suppliers may update minor parts over time.

VERIFIEDKirkland Signature, a Costco brand since 1995 We read Costco's product pages and its customer service pages.
NOT PUBLISHEDNo sag threshold or stain rule published for the Lakeridge mattressesNo sag depth or stain rule is in our research, so we cannot say what the warranty covers.
VERIFIEDKirkland Signature Lakeridge engineered with Stearns & FosterBoth Lakeridge beds are listed as engineered with Stearns & Foster.
NOT PUBLISHEDNo launch or retirement date published for the Lakeridge line Costco gives no launch or end date, so we cannot tell how old the design is.

NOT PUBLISHEDNo independent durability test of the Lakeridge published by CostcoOnly outside sites tested this bed. Their scores are in the first chapter.
Where sources disagree
Build type: Costco's listing says innerspring, while NapLab tested a 14.5 thick high-profile hybrid. Ask Costco how it labels the build.
Feel: Costco labels the Pillow Top Medium, NapLab rates it Medium, 5 out of 10, and Sleepopolis rated its bed Medium-Firm 7/10.
Trial: Costco prints no day count, while NapLab lists Trial 365 nights.
Chapter 06
Sleep trials, returns, exchanges and fees
Why this matters to you: Return rules decide what a home trial really costs. Costco prints no day count, so get it in writing.
The page names a satisfaction guarantee with a refund. It gives no number of days and no return fee, and NapLab reports free returns.
Costco's steps say: Refund processed once carrier confirms picked up and in transit. Keep the pickup confirmation.

What do the warranties cover?
Why this matters to you: Warranty years are only useful with clear terms. Costco's page names the years but our research holds no sag rule.
Costco lists a 10 year warranty for the Lakeridge line. The terms behind it are not in our research.
Costco names the warranty length on its product page. Read the full terms before you buy.
Sag rule: No sag threshold or stain rule published for the Lakeridge mattresses. Ask how deep a dip must be to count.
Ask about cost after the first years: we did not read a proration schedule, so we make no claim about one.
Covered when the dip is deeper than a depth we could not find, measured with nobody on the bed.
Strip the bed down to the mattress and wait a few hours so the top layers can recover.
Lay a straight edge (a broom handle or long level) across the dip, resting on the flat parts.
Measure from the edge down to the deepest point, then photograph the ruler for your claim.

Customer reviews and complaints
Why this matters to you: Star ratings depend on who posts where. Costco member reviews run high, and Trustpilot's page for Costco runs low, so know which is which.
Costco member reviews are far higher than Trustpilot's. The Trustpilot page covers Costco as a store, not this mattress.
How we read the reviews
We read two pools: member reviews on the Costco listing for the Pillow Top, and Trustpilot's page for Costco.
We never add the pools together. They measure different things.
Trustpilot rates the whole store. It says nothing about the mattress itself. The member pool covers one product page.
Read each platform on its own: who runs it, its rating scale, how many reviews it has, and the date we checked it.

We have not yet verified Kirkland Signature's certification claims with the certifiers themselves.
What these labels do and don't prove
No certification is verified here. That does not mean the bed has none. It means our research did not confirm one, so ask Costco if a seal matters to you.
Read your law tag
How to read the law tag in three steps
Why this matters to you: A sewn law tag lists what is inside a mattress. Read the tag on your own bed when it arrives.
Law tag guide
Law tag (no Kirkland Signature tag on file)
We have no copy of a Kirkland Signature law tag, so the card below stays blank.
The three steps
1
TENCEL Lyocell
Costco's label for this cover: "Designed to Wick Away Moisture". That is a brand claim, not a test result.
2
Indulge Memory Foam
Costco's label for this foam: "Engineered for Stearns & Foster at Tempurpedic". No density or firmness number is published.
3
IntelliCoil
Costco's label for these coils: "For Perfect Level of Support". The coil count and wire gauge are not published.
Full law tag guide, factory code decoding, and the certificate glossary live on our shared safety page.
How to read this: the law tag, the brand's own statements, and certificates each cover different things. A spec the brand doesn't publish isn't proof it's missing; it just isn't shared.

Where can you try and buy the mattresses?
Why this matters to you:Lying on a bed counts for more than any spec, and a visit costs nothing if you already have a membership.
Costco sells through its warehouses and its website. Check stock in the Costco app before you drive, since we do not know which warehouses carry this bed.
Costco says it runs 939 warehouses, 647 in the United States and Puerto Rico. Ask staff two things: whether the Lakeridge is on the floor, and how a return works.

Quick Answers
Quick Answers Before You Buy
Short answers to questions the chapters above do not cover. Prices and stock change fast, so check the listing first.
Safety and materials
Does the Kirkland Signature mattress contain fiberglass?
NapLab lists it as fiberglass free. NapLab's table reads: Fiberglass-Free Yes. The Costco pages we read do not say either way, so ask Costco if this matters to you.
What is inside the Lakeridge mattresses?
Costco names four parts: TENCEL Lyocell on the cover, Indulge Memory Foam, IntelliCoil coils, and an edge system. The brand does not publish coil count or foam density.
Does it have a safety certification?
We found none we could verify. That does not mean there is none. Ask Costco for the certificates if a seal matters to you.
Buying and policies
How long is the trial?
Costco does not publish a trial length. It names a satisfaction guarantee with no day count. NapLab lists Trial 365 nights, so get the window confirmed before you buy.
What warranty does it have?
Costco lists a 10 year warranty. No sag rule appears in the pages we read, so ask how deep a dip must be to count.
Does delivery include setup?
Costco's listing shows White Glove delivery; room of choice, setup and haul away. No delivery window is given, so ask when you order.
What is the price gap between the two beds?
The Tight Top's Queen price change is -$50 versus the Pillow Top. The Tight Top costs $949.99, and the Pillow Top costs $999.99.
