The Serafina pearl has three layers. The second layer is 3 inches of CustomWave foam which helps in better support and ventilation. CustomWave foam responds and adapts to motion, so that you get the comfort and support you need.

Total Score
Good 79%

The Sleep Science 9’’ Natural Latex mattress by South Bay International manufacturer is an all-latex mattress currently sold only through Costco. The body material is pure latex.

Generally, commonly accepted usage would blend latex from rubber tree sap with synthetic latex, but no synthetic rubber is used here.

Sleep Science 9’’ Natural Latex mattress is highly resilient with great comfort, support, and conformity. It has superior natural latex breathability that helps to keep your body warm in the winter and cool in the summer.

What Is the Construction?

The construction is simple, with just two bonded layers and the cover. The layers are made of Talalay latex and bonded with a water-soluble adhesive. The bottom layer is 6 inches of support latex foam which provides basic support for the whole mattress, with a higher degree of resiliency than the comfort layer.

The 3rd upper layer is not as firm as the support core. The stiff bounce of support latex holds the body weight of the sleeper while the layer above it does the cushioning.

Latex does not leave the sinking feeling characteristic of memory foam and is pressure-relieving. The cover consists of 37% organic cotton and the rest is a blend of polyester with 2% spandex.

How Is the Support and Comfort?

Latex is obtained from rubber and rubber is flexible and elastic, translating to incredible flexibility and great comfort to the Sleep Science 9’’ Natural Latex mattress.

Latex is neither too soft nor too hard, and the natural resilience offers the perfect resistance to the weight of the body in every position. It won’t matter what position you sleep in, latex ensures you are in shape.

If you occasionally sleep hot, you would be uncomfortable sleeping on synthetic latex mattresses because they retain body heat and warm up.

Mattresses that don’t keep cool are uncomfortable and interfere with sleep quality. Sleep Science 9’’ Natural Latex as the name suggests, is pure latex, which has open cell structure which makes it highly breathable, keeping you cool throughout your sleep.

It doesn’t retain heat and manages to keep cool even on warm nights. Latex is one of the coolest beddings you can find today.

It also provides greater muscle relaxation and pressure relief, helping you sleep easily and improving circulation. Those suffering from back problems or certain aches and pains would ideally benefit from Sleep Science 9’’ Natural Latex mattress.

Highly resilient with great comfort, support, and conformity.

The Pros

The Cons

Overall Rating

This mattress had some of the coolest most comfortable sleep for us but at the price of $2399 you would expect to get more than 9 inches of latex so we give it 7.9 out of 10.

Some FAQs

Most frequent questions and answers

Yes, It depends on the mattress brand, but Costco offers returns on its mattresses.

You have to return the mattress to the local store yourself. Costco will not refund you if you donate the mattress, though that would help someone in need.

Costco’s stock fluctuates so its better to call first before you try to pick up from your local Costco.

Their U.S. warehouses are closed on the following holidays: New Year’s Day, Easter, Memorial Day, Independence Day, Labor Day, Thanksgiving, Christmas.

To purchase your membership online, browse your membership options. You can choose from Executive Membership, Business Membership or Gold Star Membership.

In most cases no. Costco would have the mattress in a box and you would have to pick it up to purchase it if you didn’t order it online. Some brands may have a display in some Costco stores like Tempurpedic.

Costco does not sell box springs on their website, but your Costco might have them (we never saw one that does). However, Costco does sell foundations like adjustable bases and metal platform beds.

Final Verdict

Costco offers an impressive selection of mattresses, which can be conveniently filtered by size, brand, material or type. Costco is not a company that focuses on mattresses so some bed-in-a-box companies may offer a more specialized sleep experience.
This means that when buying a mattress from Costco you have to put your trust in the brand of the mattress and not think that since it’s on the Costco website it must be good. Still, Costco is a very convenient place to get a mattress.
