Best Costco Mattresses That Stood Out

Novaform Serafina Pearl Gel Memory Foam Mattress

Novafoam is one of the popular US mattress brands among shoppers at Costco. The Serafina Pearl is the best among all the models showcased by Novaform. This is a 14” gel foam memory foam mattress available without a box spring. It can be used on any platform.

With a three-layer design, it comes with a 20-year warranty and is CertiPUR-US® certified. Additionally, it is available in three firmness viz firm, medium, and plush.

Why You Should Buy?

The top layer is made with gel memory foam and is capable of making you sleep cool without any hot flushes. So if you are a hot sleeper looking for an affordable mattress under $1000, Serafina Pearl is worth considering.

Cons You Should Know

The major con can be the price as it will cost you more than $700 for a queen-size mattress. There are equally capable options available online at much lesser prices.

Sleep Science iFlip Sonoma

Sleep Science iFlip Sonoma 12" dual sided memory foam mattress

Sleep Science is another popular choice for mattress buyers at Costco. It has the maximum choice with over 30 options to buy from. It can be confusing for some buyers as the problem of plenty can get really overwhelming.

With so many choices, we feel iFlip Sonoma caters to you in the best possible way. It is a 12” memory foam mattress that can be flipped for a comfortable firmness. It has 5 layer foam design to provide you ample pressure relief. The foams are CertiPUR-US certified and the mattress has 20-years of warranty.

Why You Should Buy?

It is best for someone who has varied needs throughout the season. It is a flippable mattress with dual firmness. With one side softer and another side firmer (medium-firm to be precise), it is the best of both worlds. The color-coded cover further eases out the understanding of the firmness visually.

Being a hypoallergenic mattress, it would attract customers prone to allergies.

Cons You Should Know

It is another addition to sub $1000 mattresses, costing you $700 or more. Plus some past customers were not happy with the support and durability of the mattress after a few months of usage.

Cocoon by Sealy

Cocoon by Sealy at Costco

Cocoon by Sealy is a sub-brand by famous Sealy. It is advertised as Chill Mattress and rightly so. It is available in two options full foam – memory foam mattress and hybrid mattress. In our review 12” hybrid mattress scored better for their support to the back.

The mattress has a premium Bolsa® fabric-encased coil layer as the core of the mattress. It is majorly responsible for comforting and restful sleep. The coils are well supported by  CertiPUR-US memory foam.

The foam helps in spine alignment and reduces pressure points.

Why You Should Buy?

It is made in the USA mattress and suitable for customers not ready to plunge into a full foam mattress but looking for similar comfort. Attractively priced for price-conscious customers.

Cons You Should Know

Some people may find memory foam lacking in support as few past customers very not very happy and find it a little firm.

GhostBed 11″ Memory Foam Mattress

We would like to share our feedback and initial thoughts from our GhostBed Memory Foam Mattress Review. It is a very well made 11” full foam mattress and would go a little further in recommending with GhostBed adjustable bed frame.

If the price is a deciding factor then Costco wins hands down. There are additional discounts being offered from time to time which makes it an attractive option.

Why You Should Buy?

It is recommended for someone looking for the comfort of memory foam but hates hotbed.  It has a cooling 2” gel memory foam layer to counter heat-trapping. On the top there is 1.5” latex foam to further add to the cooling effect.

Cons You Should Know

Not recommended for someone looking for a softer bed. It is medium-firm to slightly firm in feel.

When we dug deep to understand attractive pricing and even better than the GhostBed website, we found that the trial period was less and can be counterproductive in case your body takes time adjusting to a new mattress.

Beautyrest Silver

Serta Simmons’s Beautyrest Silver is a mid-segment affordable 12” hybrid innerspring mattress. It is usually available below $600. The mattress is equipped with a solid 8” 900 Series Beautyrest® Pocketed Coils®. It has four layers of foam and together with coils provide a medium-firm feel.

It uses DualCool technology to keep heat and moisture at bay. Box spring is available at an additional cost.

Why You Should Buy?

Ideal for someone looking for a medium-firm hybrid mattress at a cheaper price.

Cons You Should Know

Some customers can continue to find it slightly firm even after the trial period. It has only a 10-years warranty which is lower than similar products. The stitching may not infuse confidence in durability.

Casper Select

Casper Select is one of our top recommendations if you are planning to purchase a mattress from Costco. It is a member-only product and if you go to the Costco website the pricing is visible only after you login.

The Casper Select mattress is designed for Costco customers by making it more affordable than Casper Original. It is exclusively sold only at Costco.

It comes very close to the look and feel of Casper Original but is not relabelled at “Select”. The quality of the mattress and firmness is different. It is a cheaper version of “Original”.

It is a 12” mattress with 4 layers of premium foam with zoned support that help in pressure relief.

Why You Should Buy?

The customers who have used or liked Casper products and specifically Casper Original. The select will help you save a couple of hundred dollars.                        

Cons You Should Know

The only Casper product is available to buy. With no option to compare with other Casper mattresses is a smart move by the company but as a customer the best mattress maybe a few hundred dollars away.

To sum up in a few words to more noticeable differences, Select lacks a removable cover and does not have an AirScape™ foam.

Things You Need to Know Before Buying at Costco

Costco is well-known and extremely accessible which in turn leads to many people buy mattresses from Costco.

 We thought that it would be useful to provide you with a small guide of what you must know before purchasing a mattress from this brick and mortar store.

The first thing to keep in mind is that the prices of mattresses at Costco vary immensely. Thus, one mattress can $300 while another maybe $2000.

Mattresses by themselves can cost an arm and a leg.

You may consequently find many mattresses being old at a much cheaper rate at Costco, as compared to the ones being sold directly by the manufacturer.

If you have enrolled for a membership with Costco, you pay lesser and don’t have to pay a surcharge.

The second thing that you must keep in mind is the warranties provided at Costco. Warranties provided there are limited in nature. In that, redeeming them is tricky.

Costco and the retailers decide under what conditions one can use the warranty. Hence not all damage and sagging are covered by the warranty given at Costco.

Next, let us look at how the delivery and shipping system works at Costco. Firstly, shipping above $75 is usually free (within the United States). However, if your order is below $75, you will have to pay a fee amount. With regards to delivery, Costco provides White glove delivery for bulkier mattresses like the King or California King size beds.

This delivery service not only delivers the mattress to your doorstep but also takes it inside and unpacks it. You may even be able to avail the next day’s service if you have a Costco membership.

The downside, however, is that if you do not have it, delivery can take several days or even weeks!

Returns at Costco are also another facet of the experience that is worth mentioning. If you have a Costco membership then you can return a mattress even six months after purchasing it.

You will even have the option of returning it directly to the manufacturer. However, this option is not available for all mattresses.

If you are not a member, you can still return your mattress. Costco has a ‘member satisfaction policy.’ Under that, you can ask for a return with a receipt.

Membership at Costco: Costco offers Gold Star and Gold Star Executive membership.

The Gold Star costs $60 annually and the other costs 120 dollars annually. If you purchase the Gold Star Executive membership, you will have additional benefits.

Hint, you will be able to choose from a more comprehensive roster of mattresses.

The Pros & Cons of Buying Mattress at Costco

There are many pros to purchasing a mattress from Costco as compared to buying from elsewhere. However, as we will find, purchasing from an online store can be more advantageous in some cases.

But first, let us look at the pros of purchasing from Costco are:

  1. Costco stores are present nationwide, especially in the US and Canada. Hence, you can purchase a mattress directly from your hometown. You do not have to drive for miles to buy the mattress you had in your mind.
  2. It is a different experience shopping at a brick and mortar store as compared to purchasing something online. You can walk down the aisle and look at the various products- you can also feel your purchase before getting it home. You may get some free samples here as well.
  3. Costco also has a variety of mattresses in its store. Additionally, all these mattresses are from well-known brands like Casper and Tempur Pedic, etc.
  4. Costco provides White Glove Delivery. However, this option is not available for every mattress. This delivery service delivers and also unpacks and sets up the mattress you have ordered.
  5. If you are a member of the Costco organization, you can avail multiple discounts and offers. The offers which will be available to you will be much more lucrative than those available online.
  6. You will also find more affordable options at Costco. Hence if you do not have $3000 to spend on a mattress, you will easily be able to find a good quality cheaper mattress at Costco.

The cons of purchasing a mattress from the store do, however, outweigh the numerous advantages of doing the same.

  1. Always make a note of the manufacturing date and model you are purchasing. At times the latest models are not available in-store and they are keen on clearing the existing inventory.
  2. You may get a lesser trial period. Usually, manufacturers offer a sleep trial period of 100 days or more. However, you may not have that same period if you purchase from a retailer instead.
  3. The warranties provided at Costco are slightly tricky, in that they come with some additional terms and conditions. Hence, the warranties given may not cover a wide variety of damages and sagging. We recommend that you contact the manufacturer before going to the retailer.
  4. The Costco online store may cause a phenomenon called analysis paralysis. That is it may have too many options which may end up confusing the customer
  5. Unfortunately, many of the organic, eco-friendly, and natural mattresses are not available at the Costco store. In today’s day and age, most of us are moving towards a more sustainable form of consumerism.
  6. You may be able to access some brands only if you are a member of this store. Casper, an extremely popular brand, is not available to non-members of Costco.
  7. The shopping experience can be inconsistent as it can be with any experience with humans at the forefront. Hence at times, you will find employees who will be extremely helpful and at other times you will find those who lack knowledge and patience.
  8. The employees may push you towards purchasing a mattress you do not need. They may point you towards a mattress just so that they can get a better commission.
  9. Some products are specially designed keeping in mind the kind of deals customers look forward to at Costco. For eg, Casper Select mattress is only available at Costco and is not sold anywhere else including the Casper website.

Overall, purchasing a mattress from a physical store may not be the best idea. This is not to say, however, that online shopping has no cons. You will not be able to immediately ‘feel out‘ your mattress.

You also will not have a salesperson next to you who will be ready to answer all your questions. Another vital disadvantage of purchasing online is that you may not find authentic reviewers.

Having said all that, we still recommend online shopping for you. Direct to consumer selling helps companies to provide better price and customer benefits as they tend to save money by eliminating hefty commissions to stores. You will find better return policies, trial periods, and warranties online.

Not only is it more convenient but it also may be more economical to purchase a mattress online as you will not have to pay the overhead costs. You will also be able to compare mattresses easily online.

Hence, Costco is an impressive store with a variety of options. But it is important to understand buying groceries is different from buying expensive electronics or luxury items from a store.

We recommend you to look for your next mattress online because of the advantages it offers.

13″ Hybrid Mattress.
Medium Firm

That was made clear by the presence of a zipper which allows the sleepers to change their feel layer every six months.

Moreover, the mattress (only in King and California King size) is internally divided. Hence, the firmness level provided on each side of the mattress is different.

One side can be plush (soft) and the other can be firm/ medium-firm. The Hybrid’s construction also allows for a cool sleep wherein the sleeper feels comfortable and supported.

The mattress has as its material the TitanChill Endurance Foam® that provides support to the consumer as he/she sleeps at night.

Additionally, this mattress has built up a base of happy customers and is cheaper than many mattresses available at Costco.


Concluding Thoughts

Costco also provides many advantages that you cannot find online. Having had said that online shopping offers far more benefits to its customers and opens up a whole new world for people whose preferred shopping avenue is in-store buying.

We recommend that you do some research before deciding to purchase directly from Costco even though it is a great store. It is only then that you can make the best purchase possible!
