The most they tend to take off is around 15-20%, which could lead to massive savings if you are buying a luxury mattress. This means you could get a bigger bed for your money.

Can you Buy Mattresses at Costco?

It offers a whole spectrum of beds and bedding. You can buy a single, double, queen, or cheap king-sized mattress from Costco, and many for competitive rates compared to buying from a manufacturer direct.

However, bear in mind that not all mattresses are available to buy from Costco, and you should check to see whether you can get a better price from the manufacturer’s website. In particular, we recommend purchasing the Saatva- our favorite mattress– direct.

As with most of its stock, Costco buys its mattresses in bulk. This business model saves a lot of money, allowing it to charge lower prices. When you go wholesale, you can often get discounted deals on mattresses. This means they have lower prices on bedding than other stores can afford to offer at Costco.

Over the years, Costco has even managed to acquire some exclusive bedding. Mattresses bought here are not only as good quality as you would buy directly from the producer, but they are also occasionally only available through Costco and nowhere else. This adds some exclusivity to the brand, along with the savings it’s famous for.

So yes, you can buy a mattress on sale at Costco. Not only that, but it will be excellent in quality and covered by the generous returns policy. You have the assurance of knowing that you will get a good quality product from a reputable brand name and that you will get a bargain to boot.

The Pros of Buying a Mattress from Costco

There are numerous benefits to buying your mattress from Costco. Here are a few of our favorite reasons to bag a bargain with a mattress sale:

  • Affordability – when you buy a mattress from Costco, you are likely to pay less than you would at most outlets.
  • Choice – Costco has a varied mix of mattresses, even when they are on sale.
  • Simplicity – Buying a mattress can be as easy as adding it to the groceries you are getting delivered.
  • Style – Contrary to popular belief, Costco stocks plenty of sleek and luxurious models alongside its budget range.
  • Functionality – a Costco mattress will do exactly what you expect it to do.
  • Delivery – Costco will deliver your new mattress right to your door, so you don’t need to push it through the store in your basket.
  • Returns – Costco has its own returns policy and will accept the mattress if you have a genuine reason for taking it back.
  • Bedding and Pillows – Buying from this chain means you can access brilliant Costco mattress deals around the corner from excellent bedding supplies. You can get a mattress protector, sheets, pillows, and duvet sets, all from the same store.
  • Online Sales – If you don’t fancy browsing for mattresses along with your grocery shop, you can buy them online. Some beds for sale at Costco are only available online.

As you can see, there are many good reasons to take advantage of a mattress sale at Costco. However, it isn’t all sweetness and light. There are a few drawbacks to buying Costco mattresses on sale, too.

The Cons of Buying a Mattress from Costco

On the other hand, there are always those that don’t like buying their mattress from Costco, citing the following reasons:

  • It makes you look cheap – If you tell someone you have bought your mattress at Costco, they are likely to think it is a budget one. Perceptions will change when you reveal the actual brand of the bed. For example, Costco has some exclusive Silentnight mattress deals that you just can’t get anywhere else. If that’s not exclusive enough, we don’t know what is.
  • It might smell like the warehouse/supermarket – Depending on where your Costco mattress has been placed or stored, it may smell like it. Factory smells are often mistaken for off-gassing. If you are worried about this, opt for hypoallergenic mattresses or mattress protectors.
  • There is limited choice in hypoallergenic mattresses. Costco sells plenty of hypoallergenic bedding products but relatively few beds.

If you can get past these few negative points, then a Costco mattress deal is an excellent way to get more mattress for your money. It can save you cash compared to buying directly from the manufacturer, and that’s the big difference.

Costco Mattress Buying Guide

If you are considering buying one of Costco’s mattresses on sale, try and consider the following things.

Mattress Hardness

Mattresses come in different hardness levels to suit different sleepers. A bed that is up to 5/10 on the firmness scale is considered soft. A mattress for sale at Costco that has a rating of 6-7.5 is a medium-firm mattress. If you like them to be hard, then 8-10 are your numbers.

Mattress Temperature

If you are a hot sleeper, you probably don’t want a hot mattress. For this reason, it’s essential to consider the heat of the mattress. Costco mattress deals cater to the hot sleeper with cooling mattresses. They cater to the cold sleeper by providing full memory foam beds. Lastly, there are hybrid beds of neutral temperature to help you sleep. Consider this copper-infused bed if you want anti-microbial bedding.

Weight Transference

You want a mattress that doesn’t see you rolling into the center of it, should your heavier partner lie in it in the middle of the night. Memory foam and hybrid mattresses are better at spreading that weight around than a sprung mattress is.

Noise Reduction

Again, if your partner wakes up in the night to go for a glass of water, you don’t want to hear it. Sprung and hybrid mattresses make more noise than memory foam or latex ones, just because of the springs.

Warranties and Guarantees

As ever, that 100% return guarantee with Costco can help you to choose the best mattress for you without all the hassle. Bear in mind that returning a bed is a hassle for everyone involved, and don’t take advantage of them. Your average mattress takes 120 years to decompose. It is highly recommended to check our lifetime warranty mattress in 2023.


Costco offers a full range of mattress sizes. We don’t just mean normal sizes, either. It stocks Twin, Twin XL, Full, Queen, King, and California King mattresses, providing a competitive alternative to buying directly from the manufacturer.


If you regularly suffer from allergies, then bedding can be a bit of a sticking point. Be sure to pick out a hypoallergenic mattress to avoid any unpleasant reactions. Unfortunately for Costco shoppers, its range of hypoallergenic options is relatively limited, although it does stock allergen-free mattress toppers.

Memory Foam/Sprung/Hybrid

Foam mattresses feature memory foam of differing densities. Usually, they feature more rigid memory foam at the bottom of the bed, with softer material at the top. The design cradles you while you sleep and may cause overheating, although some have cooling gel-infused foams. Some of the best memory foam beds sold in Costco mattress sales include the Sleep Science Black Diamond foam mattress, the Ghostbed Luxe, and the Molecule 1.
A Sprung mattress features springs and no foam and is much like the mattresses you will be familiar with from the last few decades. Sprung mattresses are swiftly going out of fashion.

A Hybrid mattress features springs wrapped in foam, usually individually. Sections of the bed will be memory foam, and other parts will be mechanically sprung. A hybrid mattress is the best of both worlds. Great hybrid mattresses from Costco mattress sales include the Brentwood Home Tahoe and the Beautyrest Silver.
As an outside bet, Costco mattress deals sometimes include latex beds. These are the most likely to be hypoallergenic mattresses.

What’s the Costco Return Policy for Mattresses?

The Costco return policy on mattress deals is exceptional. Other mattress suppliers will only accept returns if something is defective with the mattress, while Costco will simply take the return because you no longer want it or because it didn’t suit you. The returns policy means that you can get your money back in almost any circumstance, including if the bed is damaged or you decide you

made the wrong choice.

Costco may ask you to process the return via its website when the product in question is something as significant as a mattress. While you may have to answer a few questions, you’ll almost certainly be able to return it.
In the world of mattress sellers, this is huge. We would always recommend that you opt for a mattress with a long sleep trial so that you can decide whether you really want it or not over a few seasons. Costco does not offer a blanket sleep trial (excuse the pun). Instead, the trial will vary by brand. There is no standard model to draw on within the chain themselves, but the industry standard for a good sleep trial is about a hundred days.
