Our Experience with Plushbed’s Handmade Natural Wool topper
Plushbed’s Handmade Natural Wool topper is made with organic wool. The mattress is 3″ thick and made with certified materials that are free from any chemicals.
The topper cover is 100% GOTS certified organic cotton sateen which means it is very soft and airy. If you are looking to upgrade your existing bed, this mattress topper gives a plush and luxurious feel that instantly creates a visible difference.
The wool used in the Handmade Natural Wool is made up of 100% virgin ECOWOOL® fill. It is not only soft but also gives great pressure relief. These distinct qualities make it a great fit for people who are suffering from persistent body pain. The topper offers a responsive bounce to your existing bed and works great for combination sleepers.
We recommend this mattress topper to those who have an extra-firm mattress and want to add a soft touch to it. Using a soft mattress topper like Plushbed’s Natural Wool will do very well for this purpose. We found that this topper is a great fit for side sleepers as it won’t build pressure up on their hips which can result in long term hip pain.
We found that the Natural Wool topper is excellent in its heat wicking away ability and lets you sleep cool. If you live in a relatively warmer region or tend to overheat while sleeping, adding this mattress topper will provide a much cooler sleeping surface.

Our Experience with Bear Pro mattress topper
The Bear Pro is the most affordable mattress topper on our list. This mattress is a budget-friendly and convenient solution for if you are looking for a mattress upgrade.
The Bear Pro is a compact topper with one memory foam layer topped with a cover. Bear uses premium quality copper-infused memory foam which helps regulate temperature. Copper is a thermal conductor meaning it helps draw heat away to maintain an even temperature on the mattress surface. Copper not only has higher absorption abilities but is also naturally antimicrobial and keeps viruses, bugs and odors away from the mattress.
The cover of the Bear Pro is made with Celiant® fiber fabric, which also helps with ensuring temperature control. Celliant® Technology has been clinically proven to aid muscle recovery of the body. FDA has even declared Celliant® Fibers to be a medical device/general wellness product.
The Bear Pro is 2″ thick and could be too thin for heavier set individuals. However, it is particularly beneficial for gym enthusiasts, and athletes as they need a mattress that helps in muscle recovery.
The Bear Pro topper offers firm support to back and stomach sleepers. It helps to relieve chronic pain by providing support and ample firmness. It might look a little thin to some but we found that it does provide good pressure relief.

Our Experience with the GhostBed Memory Foam Topper
Next mattress topper for California King mattress toppers lineup is the Memory Foam topper by GhostBed. As the name suggests, Memory Foam topper of GhostBed offers the typical body hugging and targeted support you expect from a memory foam mattress.
The mattress topper is made with 3″ thick gel-infused memory foam encased in a waterproof cover. The cover of the mattress topper is made with proprietary Ghost Ice fabric which is not only water resistant but also has moisture wicking properties. This machine washable cover is very useful in case you have a family with small children. The mattress cover helps a great deal in preventing permanent stain marks to the foam.
The gel-infused foam has a convoluted structure to further aid in airflow and cooling. So, if you tend to sleep hot, adding this mattress topper might help you sleep a bit more comfortably. This mattress topper features five support zones that provide targeted pressure relief from head to toe.
We found this mattress topper to be primarily suitable for side sleepers who enjoy the conforming hug feel of gel memory foam. However, some back sleepers especially those suffering from chronic back pain might also like the pressure alleviating feature of this mattress topper. That said, this mattress topper is not a great fit for heavier-set people especially the ones who weigh over 230 lbs.
The GhostBed Memory Foam topper offers great motion isolation for people who are easily disturbed by the movement. If you sleep with a partner or a pet, you won’t feel any of their movements throughout the night.
The foam used in this mattress topper is CertiPUR-US certified for low VOC levels and zero heavy metals. Although there was slight off-gassing when we unboxed it, which dissipated after airing it out.

Our Experience with Tuft & Needle Mattress topper
The Tuft & Needle mattress topper is made by using hypoallergenic materials. The mattress topper adds a soft yet supportive feel to your existing bed. Like most mattress toppers, Tuft & Needle topper doesn’t radically change the feel of your existing bed but helps add extra padding and cushion.
The Tuft and Needle mattress topper cover is made with a breathable polyester blend removable fabric. It is not a machine washable cover so spot cleaning is recommended in case of any spills or accidents. We also recommend the use of mattress protectors to avoid stains.
The topper has a distinct silicone beading on the bottom layer that prevents it from sliding off the bed. The filling of the Tuft & Needle mattress topper is made of one solid block of open-cell foam.
The topper has a profile of 2″ and brings great pressure relief to pressure points. We found this topper to be a great match for people suffering from chronic back pain and are looking for an affordable fix for spinal alignment. The Tuft & Needle mattress topper is also the most economical choice on our list.
The topper is a great choice for back sleepers who are already using a medium-firm bed. Even side sleepers wanting to add little cushion for pressure relief to pressure points will find this topper to be comfortable.

What to look for when buying a Cal king topper
When you are looking for a topper for your Cal king mattress, there are a few elements that you need to consider. Multiple brands are offering different foam type, firmness, thickness, trial period, and guarantee for their Cal king toppers.
The filling of a topper can be of memory foam, latex and wool fillings. The mattress topper you choose should ideally have a thickness of 2-3 inches for a better sleeping experience. If you are sleeping on a cal king mattress then you must be sharing the mattress with a partner. You should also check the firmness level of the mattress and your preferred sleeping position. If you are a side sleeper, choose a plush topper and if back or stomach, go for a firmer option.
Different body types prefer different types of foam and firmness level. Similarly, brands offer varying sleep trial period and guarantee for mattress toppers. When ordering a Cal king mattress topper online, make sure you choose a brand that offers a sleep trial in case you are uncertain of the firmness and feel of the topper.
FAQs:
Will a king-size mattress topper fit a California king?

Is it worth getting a mattress topper?
Getting a mattress depends on your personal choice and existing bed condition. Sometimes adding a topper enhances the performance of your existing bed. In that case, it might be a great idea to add a topper. However, if the existing mattress is already in a poor condition, then even adding a mattress topper won’t make much of a difference.
Should a mattress topper be bigger than the mattress?
Mattress toppers are usually a tad smaller than a typical full mattress to avoid tearing of the edges while getting in and out of bed. Mattress toppers should not be bigger than the existing mattress.
