Ghostbed Classic
This Ghostbed blends 3 different foam types to create an effective and budget-friendly mattress that is available at Costco for $650. Its cooling and sex performance could be better, but it is still a fantastic, affordable option with excellent pressure relief.

Costco mattresses are cheaper than many other mattresses for two primary reasons:
- Costco’s membership costs and limited options mean Costco can order mattresses in bulk and sell them at a lower margin. Costco caps the markup margin on most products at 14%.
- Costco works with mattress brands to create more budget-friendly models and special model versions. The mattress brand will then design and tune the mattress so that it can be sold at a lower price point (by using less expensive materials, meaning the total cost to manufacturer is lower). This is done by choosing material types, material quality levels, foam density levels, coil unit types, coil unit quality levels, coil gauge levels, more simple covers (IE, rare to see a cooling cover or phase change materials), and other material / design choices that allow for a lower mattress cost.
Costco’s approach to sell lower spec (lower spec compared to many others we’ve tested, in my opinion) mattresses does mean their prices are lower than average. However, based on our tests of 16 Costco mattress models, the weaker performance of these mattress designs is significant.
The average performance level of the 16 Costco mattresses we’ve tested to date is 7.85. For comparison, the average performance level of all mattresses we’ve tested to date is 8.54, quite a bit higher than the Costco average.

Based on the 16 Costco mattresses we’ve tested to date, I have been unimpressed by the level of mattress performance. While the prices are indeed excellent (as is the return policy), the mattress performance and material quality have been incredibly disappointing.
As such, for most sleepers, I think there are simply better mattresses sold elsewhere. For budget-friendly mattresses that I recommend highly take a look at our Best Cheap Mattress (Under $700) and Best Affordable Mattress (Under $1,000) guides.
Both of these are fantastic resources for highlighting affordable mattresses that don’t necessarily sacrifice performance.
In the interest of full disclosure – we do not currently have referral links for Costco. When you use our referral links to make a purchase, we may earn a commission. While Costco does have a referral link program, which we have applied to join, Costco has not allowed us into their program. My assumption is that Costco has seen that our reviews of their mattresses are less-than-stellar and as a result does not want us to participate in their referral program (please know, this is a guess, Costco has not communicated this to NapLab).

Total Number of Mattresses Tested
Each best list is put through a customized performance analysis with specialized consideration given to our objective & data-driven performance tests. In addition, we consider mattress type, design, materials, value, price, and more.
For our Best Costco Mattress list, we based our selections on the best-scoring mattresses, according to our battery of testing and formulaic-driven scoring.
Our tests analyze performance across 8 critical factors, including cooling, motion transfer, response time, edge support, sex, pressure relief, off-gassing, and company. In addition, we also test sinkage and bounce (though these are not scoring factors).
Our tests include objective and quantifiable data whenever possible. In addition, we use subjective assessment supported by data to round out our testing process.
Our scores are based on mathematical formulas and equations that utilize inputs from our data-driven testing.
In choosing the best Costco mattresses we looked at the totality of all of our tests, scores, data, and reviews to date. We analyzed this data alongside our established best mattress framework here.
In addition to achieving a high-performance score, all mattresses on this list had to be available for purchase at Costco.com (within the US).
When selecting the best Costco mattress, we’re looking at a combination of overall scoring performance, price, US availability, and Costco availability..
To be included within this list all mattresses:
- Had to have a performance score of 7.66 or higher.
- Had to be available for purchase at Costco.
- Had to be available for purchase within the USA.

Ghostbed Classic
Best For
- Use of latex is rare at this price point. Responsive, bouncy, and good for cooling.
- Satisfying comfort from balance of memory foam and latex
- Exceptionally low motion transfer
Considerations
- Cooling was good, but plenty of room for improvement
- This design provides more push back – may not be ideal for lighter-weight sleepers
- Subpar sex performance
Our Verdict
The Ghostbed Classic is an 11″ foam mattress made of a combination of latex foam, memory foam, and support foam. Latex is not often used outside of all-natural or organic mattress designs, so this design makes for a unique feel, especially at this price point.
The Ghostbed Classic is available in a single firmness level — medium-firm. It is a 6 out of 10 rating, where 10 is the most firm. This is a touch firmer than the more common 6 out of 10 rating.
This mattress has deep sinkage and low levels of bounce. The latex top layer restrains the type of contour and hug around the body. Initially, there’s a little more pushback, but sufficiently heavy sleepers can sink down to experience the memory foam middle layer for a pressure relieving feel.
In our performance tests, this mattress earned an overall score of 8.76, ranking the mattress in the top 41% of all mattresses tested to date.
The Ghostbed Classic is $650 for a queen-sized mattress, which is 56% less expensive than the average mattress price. For $650 this is an incredible deal. If cooling performance were just a bit better, the Ghostbed Classic would be truly exceptional. As it is, this is the best mattress available at Costco that we’ve tested to date.

Casper Cooling Select Hybrid
Best For
- Low levels of motion transfer
- Excellent cooling performance with poly foam comfort layer + pocketed coil base
- A hybrid mattress at $850 is a fantastic value
Considerations
- Takes longer than average to off-gas (15 days)
- Sitting edge support is good, but lying support is only fair
- Pressure relief is good, but also far from amazing
Our Verdict
The Casper Cooling Select Hybrid is an 11.75″ hybrid mattress and the 2nd best Costco mattress we’ve tested so far. It has a comfort layer of poly foam and memory foam with a pocketed coil base.
This mattress is available in a single firmness, 6 out of 10, with a medium-firm feel.
It has minimal sinkage and a moderate level of bounce. A feel like this would generally be suitable for a wide range of sleepers, but some side sleepers may prefer a bit more sinkage.
In our performance tests, the Cooling Select Hybrid scored an 8.71, ranking it in the top 47% of all mattresses tested.
Priced at only $850, the Casper Cooling Select Hybrid is 45% less than the average hybrid mattress. For a hybrid mattress with above-average performance and a below-average cost, the Casper Cooling Select Hybrid is a solid pick.

Avocado Organic Hybrid
Best For
- Excellent cooling from breathable, perforated latex + hybrid design
- Fantastic pressure relief from latex foam and a high-quality organic cotton cover
- Extremely fast response time
Considerations
- Fairly high motion transfer
- Very strong latex smell that lingers 17 days or more
- Edge support is somewhat lacking, but only slightly worse than average
Our Verdict
The Avocado Organic Hybrid is an 11.50″ latex hybrid mattress made of all-natural and organic materials. Its design includes an organic cotton cover (GOTS certified), 2.25″ of latex foam (GOLS certified), a pocketed coil unit (recycled steel), and a thin latex foam base layer.
The Avocado Organic Hybrid is available in a single firmness level — medium-firm. This is a 6 out of 10 firmness rating, where 10 is the most firm.
This mattress has deep sinkage and high levels of bounce. The feel is incredibly lively and responds quickly to changes in movement and getting in / out of bed.
When it comes to performance, this mattress earned an overall score of 8.42, ranking the mattress among the bottom 33% based on all mattresses tested to date.
The Avocado Organic Hybrid is available from Costco at $1,399 for a queen-sized mattress, which is a fair amount higher than others on this list but also 38% less expensive than the average latex hybrid price. Not only that, it’s $200 cheaper when buying from Costco compared to Avocado’s own website.
Ultimately, the score is the 3rd best Costco mattress by score, and is one of a few latex hybrids the store has ever offered. While not the best score from a latex hybrid mattress, it is one of the best deals we’ve seen for one.

Purple Renew
Best For
- Excellent cooling performance with limited heat retention
- Nearly instantaneous material response time
- Off-gasses slightly faster than average (5 days)
Considerations
- Pressure relief is lacking and the mattress has a bit of a “floating feel” overall
- Lacks edge support when sitting and lying at or near the edge
- Not available in smaller sizes (Twin, Twin XL, or Full)
Our Verdict
The Purple Renew is an 11″ specialty mattress that is made of support foam, poly foam, and the patented Purple gel grid.
This mattress is available in one firmness—6 out of 10 and with a medium-firm feel.
The Renew has minimal sinkage and a moderate level of bounce. Like other Purple mattresses we’ve tested, the Renew has more of a floating feel with generalized contour. I wouldn’t recommend this mattress for side sleepers, but some back or stomach sleepers may find it to be a nice option.
In our performance tests, the Renew scored an 8.14 overall, which actually puts the mattress in the bottom 20% of all mattresses tested to date. If we look exclusively at specialty mattresses, that rank is slightly better, being in the bottom 25%. Although the score is high enough to be considered one of the “best” from Costco, it’s still not impressive compared to all mattresses we’ve tested.
The performance is lower than average, but the price is also lower than average. The Renew is $1,399 for a queen mattress, which is 5% less expensive than the average mattress (notably, the Purple Renew is $1,899 if you buy from Purple.com).

Kirkland Signature Lakeridge
Best For
- Lower levels of motion transfer
- Good pressure relief with deeper sinkage and 6.25″ comfort layer
- Good edge support when sitting or lying
Considerations
- Longer off-gassing duration (8 days)
- Cooling struggles and the mattress has higher levels of heat retention
- Lower bounce is not ideal for sex performance
Our Verdict
The Kirkland Signature Lakeridge by Sterns & Foster is a 14.5″ thick hybrid with poly foam, memory foam, and a pocketed coil base. In total, it has a 6.25″ comfort layer, which is significantly thicker than the 4.27″ average thickness.
This mattress is available in a single firmness, 5 out of 10, which gives the mattress a medium feel.
In our tests, it had very deep sinkage and a low level of bounce. Especially for side sleepers, this deeper sinkage creates a comfortable level of contour when sleeping.
The Kirkland Signature Lakeridge has an overall performance score of 8.08, ranking the mattress among the bottom 18% of all mattresses tested to date. This isn’t the level of performance we’re looking for in a “Best For” pick, but for Costco, it’s pretty good.
Priced at $1000, the Kirkland can be an attractive option for sleepers on a budget who want a medium feel and deeper sinkage.

Beautyrest Silver
Best For
- Great edge support when sitting or lying near the edge
- Fast material response time
- Great for sex performance, given the higher bounce
Considerations
- Very high levels of motion transfer—nearly 2X the average
- Struggles with pressure relief
- Cooling is good, but not great
Our Verdict
The Beautyrest Silver BRS900 is a 12″ coil mattress. It is made predominantly of pocketed coils and has a thin poly foam top layer with a tufted cover.
This mattress comes in a single firmness—6 out of 10, which gives the mattress a medium-firm feel.
It has deep sinkage and very high bounce, creating a mattress that is engaging and with an active feel.
In our performance tests, the Beautyrest Silver earned an overall score of 7.93, ranking in the bottom 16% of all mattresses tested to date. That being said, for coil mattresses exclusively, the Beautyrest ranks in the top 29% (since this mattress type typically scores worse compared to other mattress types).
As an added advantage, the Beautyrest Silver is only $550 for a queen mattress, which is 63% less than the average mattress. If you’re on a very tight budget the Silver can be a reasonable option.

Sealy Posturepedic Plus RidgeCrest II
Best For
- Thick profile height at 14″ (2″ thicker than average )
- Highly supportive edge and moderately high bounce—great for sex performance
- Sex performance is better than average
Considerations
- High motion transfer level, not ideal for couples
- Pressure relief is lacking, especially for side sleeping
- Cooling is good but not great
Our Verdict
The Sealy Posturepedic Plus Ridgecrest II is a 14″ coil mattress offering a thick comfort layer made of poly foam paired with the traditional support of an innerspring coil unit.
The Posturepedic Plus mattress offers two firmness choices: Plush, with a medium feel (5 out of 10 firmness), and Firm, with a slightly firmer feel (7 out of 10), where 10 is the most firm.
The Ridgecrest II has moderate levels of sinkage and bounce, which gives it a balanced feel of a classic coil mattress.
This mattress has a performance score of 7.88, which ranks it in the bottom 15% of all mattresses tested to date. While this is a thick mattress, bigger doesn’t always mean better. The lower quality of materials really hurt its performance across many categories, including pressure relief.
Fortunately, the RidgeCrest II has an incredibly budget-friendly price at $700 for a queen mattress. This is 53% less than the average mattress price.

Tempurpedic Supreme
Best For
- Famously low levels of motion transfer
- One of the lowest-priced Tempurpedic mattresses on the market
- Excellent pressure relief with 3.0″ of quality memory foam
Considerations
- Sex performance suffers with low bounce and poor edge support
- Extremely long off-gassing duration (40 days!)
- One of the slowest resposniveness mattresses we’ve ever tested
Our Verdict
The Tempurpedic Supreme is an 11.25″ memory foam mattress sold exclusively at Costco. It is made of 2 layers of the brand’s special memory foam that sits atop 2 layers of support foam. The bottom-most layer is cut with air channels to aid in breathability.
The mattress is available in two firmness options — medium and firm. However, we found the medium to be more like a medium-firm (6 out of 10) while the firm is a solid 8 out of 10, where 10 is the most firm.
The Supreme offers sleepers moderate sinkage and one of the lowest levels of bounce on this list.
The Tempurpedic Supreme scored an overall performance score of 7.68, which ranks it among the bottom 12% of all mattresses tested to date. Looking exclusively at memory foam mattresses, the Tempurpedic Supreme ranks in the bottom 34% of all memory foam mattresses tested.
As far as price is concerned, this is one of the most affordable Tempurpedic models on the market. However, at $1,900, it is the most expensive model on this Costco list by a wide margin.
The special formulation of Tempurpedic’s memory foam provides sleepers a unique sensation, but we see it cause problems in many categories of our tests (response time, bounce, sex). But if you’re certain you want to try a Tempurpedic mattress, this is your most budget-friendly option.

Our Verdict
The Nofavorm Serafina Pearl is a 14″ thick mattress with an all-foam construction. Its design includes a 3.0″ gel memory foam layer, a 2.5″ convoluted memory foam layer, and an 8.5″ support foam as the base.
The Serafina Pearl is available in 3 distinct firmness options — soft, medium, and firm. These options are rated at 4, 5, and 8, respectively, on our firmness scale, where 10 is the most firm. All tests were performed on the medium option.
The Serafina Pearl combines a deep sinkage with high levels of bounce. The memory foam paired with the deep sinkage creates an enveloping feeling with a dramatic contour and hug around the body.
The Novaform Serafina Pearl earned an overall performance score of 7.66, which ranks it among the bottom 12% of all mattresses tested to date. However, this overall score was significantly affected by the super-low off-gassing performance. On the plus side, its pressure relief is among the best on this list.
Another benefit of the Serafina Pearl is its affordable price of only $750. Compared to the average model we’ve tested, this is 49% less expensive. In the end, the Pearl may be an excellent budget choice for those who don’t mind the extra wait for off-gassing and the subpar cooling performance.
