Sleep Science Mattress 14
The Copper Infused Memory Foam mattress from Sleep Science has a solid shape and a copper infused foam top sheet. Despite the fact that this feature is meant to enhance ventilation and temperature control, some sleepers have complained about warm sleeping surfaces.
What if you could sleep better and feel more rested without having to worry about the time of night, how long its been since your last nap or what kind of diet youre on? The answer is Sleep science copper infused mattress. Copper has an anti-inflammatory property that reduces pain from arthritis, swelling and even heart disease. It also helps with improving sleep quality by regulating temperature and reducing excess sweating during the night. Overall, this means less tossing and turning throughout the night for improved REM cycles that lead to feeling more refreshed in the morning!
What Is A Split King Size Mattress
A split king mattress is a king size mattress split in half, with each side equal to a twin XL size mattress. Split king mattresses let couples personalize their side of the bed to their preferences, preventing sleep disturbances. If one partner is a side sleeper who needs a soft mattress and the other a stomach sleeper who needs a firm mattress, a split king lets them prioritize their sleep health while still sharing a bed.

Can You Feel The Split In A Split King When Youre Sleeping
While there is a gap in a split king mattress because it is two mattresses joined together, most sleepers cant feel it because the mattresses are designed to fit so closely together. If you prefer not to feel the gap at all, options include:
- using a bungee cord to strap the legs together
- purchasing a gap filler, which is typically a piece of foam you put between your mattresses
- using a king-sized mattress topper on top
Keep in mind that some of these solutions, such as using a king-sized topper, may impact the functionality if youre using an adjustable base. That is, you wouldnt be able to raise one side of the bed up if youve got a split king adjustable underneath the mattresses.

Why Would You Need A Split King
Split king mattresses are most often used by couples. Partners dont always have the same sleeping needs. Body size, position, and personal preference affect what feels comfortable. A split king allows each partner to choose their own distinct sleep surface while still sharing a bed.
Differing Firmness Needs
Body weight and sleeping position are two of the biggest factors when choosing an appropriate firmness level. Couples needs can vary widely in this regard. For instance, a stomach sleeper over 230 pounds is likely to need a much firmer mattress than their partner who weighs under 130 pounds and sleeps on their side.
Motion Isolation
When a person tosses and turns or gets out of bed, vibrations may travel across the mattress surface and disturb their partner. Since a split king is two separate pieces, movement on one side of the bed does not transfer to the other.
For Use on an Adjustable Base
Sleepers may use an adjustable base for a wide variety of reasons, including comfort, mitigating snoring, and preventing acid reflux. Combining an adjustable base with a split king allows each partner to customize the position of their bed.

NEEDS GOOD FOUNDATION – dont use bunky board!
We bought this mattress over a year ago…had no idea that they sold a separate foundation. Spent months replacing the bunky board we got from Crate and Barrell 2 times and dealing with back pain, even called the mattress mfr. The mattress mfr said they recommend their foundation instead of bunky board. Ordering it today, hopefully it will take care of the problem but paying $50 more than if I bought them together from the start. They need to update the description and recommend the foundation if they don’t buy it separately OR don’t even sell the mattress alone. Description said it needs a ‘solid’ foundation…what does that even mean? I had a hard time trying to find a bunky board that is solid wood from many retailers. Crate and Barrel’s new bunky board is made of compressed cardboard! A painful process, but I like the mattress.
Works well for us
The mattress is definitely on the firm side but we both find it about right. After 11 months, the bed seems to be wearing very well… no signs of change in feel or shape. The adjustable bed is used in zero gravity every night for one of us and not used at all for the other. The adjustable bed works well for back sleepers but not side or stomach sleepers.
Six years later, we still love it!
Not so great!!
very good customer services
Super Comfortable great support
Helps with my back
L-O-V-E IT!!!!!!!
Wonderful Bed!

Should You Buy A Mattress From Costco
There are undoubtedly some pros and cons to weigh out when deciding if you should buy a mattress at Costco. The pros of buying a Costco mattress include the convenience, the wide range of selections, and competitive pricing compared to other retailers. If youre already planning a trip to this wholesale store, it makes sense to consider purchasing your next mattress from here. Its also nice that you can consider many mattresses from multiple brands all from one retailer.
Of course, there also are some downsides with purchasing a mattress from Costco, the main one being that its better to purchase directly from the brand. When you purchase a mattress directly from the brand, it makes the process more seamless, especially when it comes to dealing with sleep trial periods, returns, and warranty claims. You will also almost always save money by shopping directly with the brand

Pairs Perfectly With An Adjustable Base
To really kick your sleeping arrangements up a notch, your best bet is to put your split king mattress on top of a split king adjustable base.
Heres why: with an adjustable base, you and your partner can also position your mattress any way you like, at any time. Is your spouse going to bed early, but you want to stay up and watch TV? Do you want to sit up to read, but your partner wants to zone out in zero-gravity mode? With a split king adjustable base, you can each relax in style. When youre ready to snuggle, sync your settings and cozy up.
Neutrality Of Temperature Of Sleep Science Mattress
How much body heat is stored influences the temperature of a mattress during the night. Temperature neutrality is influenced by a number of variables, including substrate structure, layer thickness, and heat dissipation by airflow.
Memory foams hugging properties can render these mattresses really cosy, but they can also make people sleep heavy. This is particularly true since as memory foams temperature rises, it becomes more sensitive, potentially the the amount of sink or embrace experienced while sleeping. Many of the Sleep Science models mention increasing air flow or regulating temperature, but its difficult to know how powerful these interface features are. Although the manufacturer has invested in designing their mattresses to attempt to reduce the phenomenon of sleeping heavy, many consumers also find heat retention to be a problem, similar to that of other memory foam mattresses.

What Other Problems Are Common With Split King Adjustable Beds
The most common problem that people face with a split king is the gap in the middle, as we mentioned in the last FAQ. Beyond that, some people worry about the mattress sliding down when youre elevating your head. To combat this, look for an adjustable base with a retainer bar at the foot and non-skid material beneath each leg.
Another common complaint to note: as you raise the head of some adjustable bases, the entire bed moves forward and can leave you far from your nightstand or anything else by the side of your bed. Some companies add wall-hugging or wall-aligning technology to their base to help with this others are simply designed to keep you close even as the bed adjusts.
In my experience, theres not a huge difference between bases with wall-hugging features and without. Its typically about a 4 difference, so its not a lot! Even with wall-hugging features, you may not end up as close to your side table as you might think.

Great mattress at a great price – Matthew S.
I received ghost mattress promptly as well as my foundation. I was thrilled I did’nt have to go to a mattress store and everything was delivered at my convenience. I sleep great and I love the ghost pillows as well.
Not what I dreamt – Mark N.
Though the Ghost bed is way better than what we had, it is not as comfortable as we expected. The first week was great. But after that, the back and hip pain was back,though not as bad. The Ghost bed is much too firm for me.
Love it! – Taylor H.
Ive had my Ghost Bed for a little over a month and its been a great experience! I had forgotten to apply my promo code and checkout, and the customer service team was an incredible help at getting it applied and getting me refunded for the additional amount. The bed is incredibly comfortable and feels like laying down on a cloud at the end of a long day. I got two pillows as well and theyre great at keeping me cool throughout the night.

Pros Of A King Mattress
- At 6080 square inches, a king size mattress offers couples plenty of personal space. Theres even enough room to co-sleep with a child.
- King mattresses are compatible with adjustable bed bases. However, you must set up the base to move the mattress as a whole otherwise the base will try to move each half independently.
Durability Of Sleep Science Mattress
The Sleep Science mattresses have little hard evidence, and reliability can differ from model to model due to the varying nature of materials used in each. Models with lower-quality comfort foams are more prone to have long-term longevity issues, but alas, Sleep Science and Costco do not disclose the density of any of their mattresses layers.

Best Suited To Combination Sleepers Sleep Science 12
The iFlip Sonoma Dual Comfort Memory Foam Mattress features an interesting reversible design, with a medium-soft side and a medium-firm side that can simply be flipped to suit your preferences.
If you find that your firmness preferences tend to change, or you change positions a lot in the night, the versatility of this mattress is a strong contender. This bed is advertised as a California King size, but it should be noted that the beds come in two split mattresses, allowing you to customise your side of the bed without affecting your partner.
Sleep Science Mattress Review
The Sleep Science line of mattresses is manufactured by South Bay International, and most of these models are built with memory foam. These mattresses are sold in Costco and through Costcos website and offer many potential values for those seeking this type of mattress.
Some of the key strengths of the Sleep Science mattresses include
- Many size and price options: with numerous mattress models and price points, sleepers can identify the Sleep Science mattress that best fits their firmness preference and budget.
- Costco return policy: the warehouse store has a strong reputation for service and returns, which gives customers an opportunity to test out the mattress for an extended period.
- Strong motion isolation: most of the Sleep Science mattresses have a top comfort layer of high-density memory foam, and one of the biggest strengths of this type of material is its motion isolation. For people sharing a bed, motion isolation helps ensure that one persons movements dont disturb the other.
Potential drawbacks for the Sleep Science mattresses include
- Only available through Costco: because these mattresses are only available through Costco, they are not a viable option for people who arent Costco Warehouse members.
- Negatives of memory foam: memory foam mattresses arent right for all sleepers as some customers find them to have too much sink and be too hot and, too restrictive of movement.
