Best Costco Mattress (2024)

Why the Kirkland Signature Lakeridge Earned Editor’s Pick

The Kirkland Signature Lakeridge mattress is what we’d consider a luxury-quality hybrid with coils and foam. This bed has features you’d expect from a luxury mattress but without the hefty price tag, which is why we chose it as our Editor’s Pick. 

This bed comes with a Tencel™ cover. This material is always a nice addition for hot sleepers because it’s moisture-wicking. Additionally, The Kirkland Signature Lakeridge has a medium firmness to it, which I think should work for most people since medium-firm beds usually do best at balancing support and comfort for the widest range of sleepers.

What’s the Kirkland Signature Lakeridge Made Of?

The Kirkland Signature Lakeridge mattress is 14.5 inches tall and features memory foam and coils for a balance of pressure relief and support. 

What We Liked

• White glove delivery – This mattress comes with white glove delivery, which includes old mattress removal. This means that professionals will install your mattress for you. However, the delivery coverage is within 50 miles of a Costco warehouse, so make sure to check that you’re close enough.
• Versatile firmness – A medium firmness is often a good choice for many people as it has a more universally accommodating feel. The Signature Lakeridge mattress is not too firm or soft, so you should be able to enjoy proper weight distribution, adaptive support, and pressure relief across its surface.

Potential Drawbacks

• Only available in large sizes – The Kirkland Signature Lakeridge is only available in Queen, King, and California King. This means you’re out of luck if you’re after a smaller size such as Twin or Twin XL. 
• It’s heavy – One thing about this bed-in-a-box mattress is that it’s heavy, according to customers. It comes with white glove delivery, so you don’t have to think about setting it up, but its weight can be an issue if you ever decide to move or change bedrooms. 

Customer Reviews of the Kirkland Signature Lakeridge Mattress

The Kirkland Signature Lakeridge has an average rating of 4.3 out of 5 stars on Costco’s website, with over 7,000 reviews. Overall, reviews of this mattress are positive, those some people have expressed that the bed felt much harder to them than they expected.

Why the Leesa Legend Earned Best Costco Mattress for Back Pain

The Leesa Legend is a medium-firm mattress with two layers of coils for support and responsiveness, both of which are important to people with back pain. While the supportive coils help keep the body lifted and in a healthy alignment, the responsiveness they offer can help those with back pain move around on the mattress more easily. 

As mentioned, the Leesa Legend has a medium-firm feel to it. This is great news for those with back pain as systematic research points to medium-firm mattresses¹ as the best choice for comfort, sleep quality, and spinal alignment.

What’s the Leesa Legend Made Of?

The Leesa Legend is 12 inches tall. The construction starts with a sustainable cover made from organic cotton, Merino wool, and fiber from recycled water bottles. It feels soft and gentle on the skin, but it’s also moisture-wicking and resistant to bacteria, mildew, and mold.

What We Liked

• Luxurious materials – The Leesa Legend has organic cotton and Merino wool, both of which add a touch of luxury to this mattress. Not only that, but these materials help with temperature regulation, which is helpful if you run hot at night. 
• Pressure relief – The Leesa Legend includes memory foam in its construction. Memory foam is exceptional at relieving pressure, which should help you feel even more comfortable on this bed.

Potential Drawbacks

• Might not be firm enough for stomach sleepers – As it’s a medium-firm mattress, it may not be firm enough for stomach sleepers with back pain. The reason for this is that stomach sleepers generally need firmer beds to keep their hips lifted and their lower back from curving. 
• Too soft for heavier sleepers – Similar to stomach sleeping, the Leesa Legend’s medium-firm feel might not be enough for some heavyweight sleepers over 230 pounds.   If you’re a plus-size sleeper with back pain, a supportive mattress specifically designed for heavy sleepers might be better to help ensure you’re as comfortable as possible.

Customer Reviews of the Leesa Legend

Costco’s Leesa Legend rates at 4.4 out of 5 stars on the retailer’s website. Multiple customers have pointed out the bed’s quality design. However, several customers mentioned how heavy the mattress was,

Why Simply Modern Earned Best Affordable Costco Mattress

Simply Modern is a hybrid mattress with three layers of foam and a unit of innerspring coils. While the coils should deliver plenty of bounce and support, the plush memory foam can give plenty of cushioning to ease pressure in the hips, knees, and shoulders. 

This bed has up to 975 coils in the support layer to ensure your body stays aligned in various sleeping positions. However, what stands out the most to us is that it’s not as expensive as other hybrids, so that’s a plus if you’re a budget shopper. 

What’s the Simply Modern Made Of?

The Simply Modern mattress is 12 inches tall, featuring four layers that combine foam and coils. The construction starts with a breathable soft stretch knit cover. 

What We Liked

• Affordable price – Hybrid mattresses are often more pricey because it’s an advanced mattress design. However, the Simply Modern mattress is reasonably priced, making it great for hybrid fans who are on a budget.
• CertiPUR-US® certified foam – The foams in this mattress are certified by the CertiPUR-US® program, which is a third-party tester. This is an important certification for poly foam and memory foam materials as it signals you’re buying a safe, quality-made product.

Potential Drawbacks

• Questionable edge support – Some customers have expressed that this mattress doesn’t have the best edge support, even with the reinforced perimeter. You might feel alright lying near the edge, but sitting here may not feel as secure.
• Not for lightweight sleepers – The Simply Modern mattress is labeled as medium-firm, but some people might feel like it’s firmer than it actually is. If you’re lightweight and prefer sleeping on your side, you might be better off with a softer bed.

Customer Reviews of the Simply Modern

The Simply Modern has a 4.2-star rating on Costco’s website, with over 2,300 reviews. Multiple customers have said that it’s a good value and a lot of bang for your buck. However, some people have mentioned the edges are too soft.

What’s the Helix Midnight Made Of?

The Helix Midnight is 11.5 inches tall, so there’s only a half-inch difference compared to the Simply Modern mattress. What sets it apart is that it comes with a breathable knit cover, but there are another two options available for more cooling: a GlacioTex™ cooling cover and a GlacioTex™ pillow top. 

Customer Reviews of the Helix Midnight

The Helix Midnight rates 4.5 stars out of 5 on Helix’s website. The main negative is that reviewers tend to find it too soft for their liking and feel as though they’re sinking. But overall, users say they’re getting a great night’s sleep and some pain relief.

Why the Sealy Posturepedic Earned Best Costco Mattress for Couples

The Sealy Posturepedic is a 12-inch tall hybrid mattress that should fit many people thanks to its medium firmness, pressure-relieving materials, and support system. This is also why we feel it should work well for couples since it can accommodate more body types and sleep styles.

As mentioned, the Sealy Posturepedic has coils for strong support, but this also gives the bed some bounce sexually active couples usually appreciate because it makes it easier to reposition. On top of that, it has memory foam for pressure relief and motion isolation. The motion isolation is helpful because it means movements shouldn’t transfer across the mattress and as such, you shouldn’t feel so much of your partner’s tossing and turning.

What’s the Sealy Posturepedic Made Of?

This Sealy Posturepedic mattress has a high-quality construction with multiple layers. It starts with a ComfortLoft™ cover featuring SealyChilly™ and Surface-Guard Technology™ for cooling and mattress protection. 

What We Liked

• Hybrid construction – Don’t get me wrong, I love a good all-foam bed. However, there’s something about hybrid mattresses that makes them slightly more suitable for couples, particularly because they can give couples some bounce without sacrificing so much on motion isolation. Plus, they’re often better for edge support, which means more useable surface space for spreading out.
• Cooling features – The Sealy Posturepedic has a cooling cover, gel memory foam, and coils for more breathability. All of this makes it worth considering if you or your partner sleep hot. 

Potential Drawbacks

• No King-size option – At this time, this Sealy mattress is only available in Twin, Queen, and California King, which means you’re out of luck if you want a King. However, they may be temporarily out of stock so I suggest checking with Costco to see if they’ll have a King size available soon.
• Motion isolation may not be as good as all-foam beds – The company did a good job of ensuring as much motion isolation as possible; it has multiple foam layers on top of encased coils, all of which should help absorb movements. However, couples with particularly different habits might prefer an all-foam bed for even stronger motion isolation.

Customer Reviews of the Sealy Posturepedic

The Sealy Posturepedic 12″ is rated 4.4 out of 5 stars on the Costco website. One customer shared she didn’t even notice when her spouse rolled over and got out of bed. Another couple did mention how heavy the mattress is, though they still enjoyed it.

Why the Sleep Science Bamboo Cool Earned Best Cooling Costco Mattress

Cooling is a big factor for mattress shoppers who often struggle to sleep because they either run at night or their current bed space doesn’t provide enough cooling for them. If you often find yourself overheating, sweating, and looking for a cool spot in your bed, you probably know what I’m talking about. 

When it comes to Costco mattresses, the Sleep Science Bamboo Cool is designed with cooling in mind, as the name suggests. This memory foam mattress has air channels, a cooling cover, bamboo, charcoal, and gel memory foam, all of which promote breathability and cooling.

What’s the Sleep Science Bamboo Cool Made Of?

This 12-inch mattress has a cooling cover that’s removable and washable. This is always a plus for hot sleepers because it lets you clean the cover easily if you sometimes sweat too much.

What We Liked

• Machine-washable cover – We don’t often come across mattresses with a washable cover, so it’s a nice addition. More so, if you’re a hot sleeper, you’ll appreciate being able to remove and wash it for a refresh.
• Firm feel – This bed is labeled as Firm. This should be fantastic for stomach sleepers and anyone who needs more sturdy support from their bed. That said, lightweight side sleepers may want to steer clear of it since it’ll probably be too firm for them and could wind up creating more pressure buildup.

Potential Drawbacks

• Limited bounce – This bed is only made from foam so don’t expect much bounce from it. Although this might not be a bad thing for everyone, it leaves a little to be desired if you want more buoyancy for repositioning. 
• No smaller sizes – This Costco bed is only available in large sizes including King, Queen, and California King. Therefore, if you need a smaller size, you may want to check out a different Costco bed or our Sleep Science Bamboo Cool alternative below.

Customer Reviews of the Sleep Science Bamboo Cool

The Sleep Science Bamboo Cool has a 4.4-star rating, with over 1,300 reviews on the Costco website. Multiple people have loved how firm this mattress is and have mentioned that it does a good job of keeping cool. However, there was some criticism about the bed’s off-gassing smell.

What’s the Bear Elite Hybrid Made Of?

The Bear Elite Hybrid is 14 inches tall, featuring a hand-quilted cooling cover with PCM fabric and Celliant® fibers. The cover is gentle on the skin and makes the bed feel luxurious. 

Customer Reviews of the Bear Elite Hybrid

According to Bear’s website, the Bear Elite scores about 4.5 out of 5 stars. Some customers find the Bear Elite Hybrid mattress too firm for their liking, but it receives praise in its reviews for its advanced cooling technology and pressure relief.

Why the Beautyrest Silver Earned Best Luxury Costco Mattress

If you thought Costco doesn’t offer top-of-the-line mattresses, then it’s time to put those thoughts to bed. The Beautyrest Silver offers a premium design that should appeal to those looking for the best of the best. 

The mattress has four foam layers and an innerspring base for some added bounce that makes it easier to get in and out of the bed. Additionally, it has a cooling cover and cooling foam to help hot sleepers stay cool and comfy all night long.

What’s the Beautyrest Silver Made Of?

The Beautyrest Silver is a hybrid mattress with five layers measuring 12 inches tall.

What We Liked

• Temperature-regulating features – If you tend to overheat when you sleep, the Beautyrest Silver mattress might help you feel more comfortable with its multiple cooling features. These include the cooling cover, cooling foam, and the coils.
• Reasonable price point – Although I’d call the Silver mattress a luxurious one, its price point is still reasonable. In other words, it gives that luxury feel without breaking the bank.

Potential Drawbacks

• It takes some getting used to – According to some customers, the Silver mattress takes a while to break in. This means the initial feel of the bed might change within the first few weeks. 
• Not for the lightest sleepers – This bed has a medium-firm feel, according to most of its customers, so I assume it might feel a little too firm for those under 130 pounds. This is especially the case for side sleepers. 

Customer Reviews of the Beautyrest Silver Mattress

The Beautyrest Silver has been reviewed nearly 6,000 times and has a 4.2 out of 5 rating. One customer noted that this bed even has that hotel feel. However, a few people have mentioned depressions in the mattress areas where they slept showing up earlier than expected.

Why the Sleep Science 14” Earned Best Firm Costco Mattress

If you have ever searched for a firm Costco bed, you probably came across the Sleep Science 14” mattress. This all-foam bed was specially designed to provide a firm feel. Firmer mattresses are often more beneficial to stomach sleepers, heavyweight sleepers, and those who want to sleep on top of their bed more than in it. 

This memory foam model features copper, a patented edge support system, and a 14-inch profile that should look good with any bed frame. The copper should help keep the mattress cool, but if you’re an extra-hot sleeper, you may prefer something that also has coils for added airflow.

What’s the Sleep Science 14” Made Of?

The Sleep Science 14” mattress is a memory foam model with a firm feel designed to provide continuous support without sagging.  

What We Liked

• Copper-infused memory foam – Copper is often used in memory foam mattresses to make them more cooling. Although it’s not as significant as, for example, a cool-to-the-touch cover, it does help with temperature regulation. 
• No sagging – This mattress should be firm enough to ensure you stay elevated on the surface without sinking more than necessary for pressure relief. This firm design can be especially helpful for stomach sleepers, who need to keep their hips level so the lower back doesn’t curve too much.

Potential Drawbacks

• Limited size options – Like many other Costco beds, this Sleep Science mattress is only available in Queen, King, and California King sizes. If you’re after a smaller bed, you’ll have to look elsewhere. 
• No bounce – This bed has virtually no bounce due to its firm memory foam layers. Sexually active couples and people with mobility issues might want more responsiveness than the Sleep Science 14” can give.

Customer Reviews of the Sleep Science 14”

On Costco’s website, the Sleep Science 14″ mattress has 4.3 out of 5 stars for its overall rating. Customer reviews are mostly positive, with some people saying that even though it’s a firm bed, it’s still comfortable for them. However, some customers have said it’s not as firm as they were expecting. 

Why the Novaform Earned Best Costco Mattress for Pressure Relief

You can get the Novaform Serafina Pearl mattress in a Plush, Medium, and Firm feel, depending on your preferred sleeping position and body weight. Regardless of the firmness level, the Novaform’s memory foam should do a good job of cradling the body and relieving pressure while also supporting a healthy spinal alignment. 

Although it features memory foam, this bed is unlikely to overheat thanks to its Smart cooling cover and gel beads infused in the comfort layer. 

What’s the Novaform Made Of?

The Novaform mattress is 14 inches tall, featuring all-foam layers that give it a cradling feel with plenty of pressure relief. The Smart Cooling Cover is enhanced with 37.5® technology to regulate temperature in both summer and winter. 

What We Liked

• Good motion isolation – All-foam mattresses often have good motion isolation, and the Novaform should be no exception. This means that movement from your partner isn’t likely to disturb you on your side of the bed, which can translate to more restful sleep.
• Three firmness levels – This Novaform bed is available in Plus, Medium, and Firm. Having options is always nice as it makes it easier to pick a firmness that suits your needs the most. 

Potential Drawbacks

• Not the best edge support – Some customers have mentioned the Novaform mattress doesn’t have the best edge support, which is not unusual for memory foam beds. However, this is mostly an issue if you’re often sleeping or sitting near the edge. For example, couples who like to spread out might prefer better edge support, whereas it probably isn’t as crucial to solo sleepers.
• Large sizes only – The Novaform Serafina Pearl is another Costco model that’s only available in larger sizes. As such, it’s probably not the best option if you’re looking for something more compact for a kid or teen.

Customer Reviews of the Novaform Mattress

The Novafoam Serafina Pearl has a 4.3 out of 5-star rating on Costco’s website and over 7,000 reviews. Multiple people have mentioned how comfortable and cozy the Novafoam is, though several people said the Medium model was too soft for them.
