Costco Mattress Reviews: A Comprehensive Guide

If you’re thinking of buying a new mattress, first you’ll want to check out our Costco mattress reviews. There are many things to consider before purchasing a mattress. You should consider the place you’re purchasing from, the manufacturer and the product itself.

Mattress retailers often have warranties and return policies that are different from their mattress manufacturers. You have to pay attention, follow the numbers and read reviews if you want to make sure you can consider yourself an informed consumer.

Costco doesn’t make mattresses themselves; they retail a handful of lines that include memory foam, latex, and innerspring options. The brands Costco currently offers include:

• • Spring Air – They have been making innerspring mattresses since 1926. Though they now sell latex and foam mattresses, most of their collections contain springs.
  • Novaform – This line is available exclusively through Costco. Sleep Innovations Inc., in business since 1996, manufactures all Novaform mattresses, and the brand also produces collections sold at Amazon and Walmart.
  • Sleep Science –  This is a low to middle-priced memory foam mattress brand manufactured for Costco by South Bay International, in business since 1993.

In this review, we selected a popular mattress from each of the five different brands available at Costco to sample for reviews. Keep reading to compare these lines on price, specifications, mattress type, and owner reviews. You can read our overall guide to the best mattress reviews here.

About Costco

You’ve probably heard of Costco, a well-known, nationwide warehouse club. You may even be a member. Costco is known for its cartoonishly huge boxes of food products and household items because most of the store’s goods are bulk-packaged, mattresses excluded.

You will need to become a member because this retailer only allows members to make purchases in their stores, or pay a 5% upcharge for items sold online. Members can bring up to two guests, but those guests cannot make a purchase. Memberships start at $55, so if you are not currently a member, you should add that amount to the purchase price of the reviewed mattresses, as you will incur it if you make a purchase.

The Costco Mattress Lineup

Costco may be the best place to buy a year’s supply of Cheerios, but is it a good place to get a mattress? We are here to answer that question for you. Our staff took a look at several of Costco’s best-selling mattresses and compiled our results in this easy-to-read review. Mattress shopping can be confusing and we’re here help make the process a little smoother.

The mattresses we reviewed range in price from $699 to $1,799 for queen sizes. Two are innerspring and foam hybrids, one is a latex and memory foam hybrid, and the other two are made from memory foam. Each of these types of mattress proves quite different from the others and possesses unique qualities. Costco also carries adjustable beds, but we wanted to focus on mattresses for this article.

In the following table we compiled information regarding mattress type, composition, price, and consumer reviews. Take a look at how these five popular Costco mattresses stack up:

Overview of Costco Mattress Reviews

The mattresses Costco offers are much like the rest of their products. They are all nearly in the middle in regards to price range in mattresses, with varying degrees of value. Costco offers familiar brands along with some brands which are exclusive to their store. For example, you can purchase the GhostBed Classic along with a selection of other GhostBed products through Costco.

On their website, you can find some really honest reviews. They don’t seem to delete negative comments to improve their image as some retailers do. Their customers have a fairly open forum to voice their concerns which provides the public with a legitimate view of their products. From their customers reviews and independent mattress review sites, we gleaned the following about their products:

• B- overall rating
• Below-average durability/longevity
• Average value potential
• Average pain and pressure relief
• Mostly firm and soft with few medium-firm options
• Above-average reports of off-gassing (foams)
• Average reports of sleeping hot

Costco Mattress Reviews: Pros

• Above-average consumer satisfaction
• Average pain and pressure relief
• Customer service is above average
• Return policy is excellent
• Little or no noisiness
• Available at many locations nationwide

Costco mattress ratings from consumers show a slightly above-average satisfaction rating. Several reviewers reported sagging or impressions not long after purchasing, but also said their pain was reduced from using the mattress, especially within the Novaform mattress reviews.

This retailer is a trusted name among consumers. Costco is known for treating their members well and having an excellent return policy. Many of the poor reviews on their site claimed the customer was still able to return the mattress or listed “return policy” as one of the product’s pros. As a store with a membership fee, you can expect some perks.

These mattresses are widely available at the chain’s many stores nationwide. They may not have a showroom at the Costco near you, but you can have mattresses shipped to the store’s location.

Costco Mattress Reviews: Cons

• Below-average durability/longevity
• Difficulty moving on mattress
• Firmness consistency issues
• Above-average reports of off-gassing
• Quality information may be limited

Costco mattresses score better than average overall compared to many other discount lines, but there are some things to look out for. Across several categories, there were some consistencies in the consumer reviews.

Many customers said their mattress was not the firmness level they expected. This can be an issue with memory foam and latex mattresses, and also a side effect of not being able to try the beds. The processes used to make some foam mattresses (particularly those imported from China, can create inconsistencies from one mattress to the next. The Novaform reviews consistently mentioned this as a problem, as did some of the other options.

Off-gassing was an issue with several of the memory foam mattresses. This is common for memory foam mattresses as a whole, but Costco mattresses receive slightly more complaints than average.

Another point to consider is that for many of the beds, information on quality proves fairly limited online. For example, it may be very difficult to find foam densities, material compositions, coil counts, and other important specifications that consumers should have when comparing mattresses. And, since many of the lines are exclusive to Costco, comparison shopping between retailers also can present a challenge.

Still, it might be easier to find information on some brands and constructive value if they’re independent of Costco. As we mentioned, GhostBed sells their mattresses through Costco. So even if you’re not satisfied with how much information Costco gives you on, for example, the GhostBed Luxe, it’s a simple matter to head over to GhostBed’s website and read the full details

Saving More on Costco Mattresses

While Costco is well-known for their year-round value prices, carefully choosing when you shop can enable you to save even more on a new mattress. The best times to buy a new mattress include the following:

• Presidents Day Mattress Sales
• Memorial Day Mattress Sales
• 4th of July Mattress Sales
• Labor Day Mattress Sales
• Columbus Day Mattress Sales
• Black Friday Mattress Sales
• Cyber Monday Mattress Sales

However, if you need a new mattress before one of the year’s big mattress sales is due to happen, we recommend you look into buying a new mattress as soon as possible. Costco and many other popular mattress brands tend to offer excellent prices year-round, so you can still find a good deal on a well-made bed.

Frequently Asked Questions

Are mattresses on display at Costco?

No, Costco does not have showroom models you can try out. However, they do have a generous return policy that lets you return a bed you aren’t satisfied with. Our online mattress guide has details on judging a mattress you haven’t seen or touched.

Can you return a mattress to Costco?

Yes, a mattress you bought from Costco falls under their return policy. You should have at least a few months to return it and should receive a full refund after you return the mattress. You can contact Costco’s customer support if you want more details on returning a mattress.

Can a mattress last 20 years?

It’s unlikely that a mattress will feel comfortable for 20 years if you use it every night. Even high-quality beds often last only 10 to 15 years. A guest room mattress may still feel comfortable after 20 years since it’s only used occasionally.

How often should you replace your mattress?

Many people find their beds don’t feel as comfortable after 7 or 8 years. However, high-quality mattresses may last more than 10 years.

Check the condition of your mattress for any visible sagging or lumps. Then, ask yourself how well you’re sleeping. If your mattress looks good and you’re waking up refreshed and pain-free, you don’t need to rush out and replace it.

Do you need a box spring with your mattress?

If you’re buying a traditional innerspring mattress, a box spring can increase your bed’s comfort and raise the bed height. However, a box spring shouldn’t be necessary for a hybrid or foam mattress. You can even damage a foam mattress if you keep it on a box spring.

Verdict from Costco Mattress Reviews

Costco mattresses rated on par with most mattresses in the same price range. One thing we learned is that with with Costco mattresses, price and owner satisfaction are not directly proportional. That is, as price increases, satisfaction won’t necessarily also increase. You should be wary of this while shopping for any mattress; don’t be fooled by clever marketing.

If you are going to buy a mattress from Costco, make sure you understand the issues many of their mattresses have with longevity. Their return policy is good, but you still may end up needing a new mattress sooner than you expect. And while their return policy is better than most, mattresses can still be difficult to return. You want to buy something you can keep and taking a look at Costco mattress reviews before buying can help you gain insight and avoid potential problems.
