What size is a cal king mattress topper?

A California king mattress topper measures 72″ wide by 84″ long. This is 4″ thinner and 4″ longer than a standard king size mattress. A cal king topper will fit perfectly on a California king mattress but will not work for a standard king size mattress. 

How much does a cal king mattress topper cost?

A Cal king mattress topper is going to cost between $150 and $500 for a quality mattress topper that will provide proper support and last. While a quality memory foam topper will cost in the $250-$350 range, a latex topper will generally be on the higher end due to the simple fact that it it a naturally made material and costs more to produce. You will find less expensive mattress toppers on the market that may look the same as some of the more expensive toppers and you may be tempted to purchase one of those, don’t do it. Cheap toppers are made with cheap low density foam that will not support your body and will break down quickly. 

What to look for when buying a cal king topper

Here are a few factors that are important to consider when buying a mattress topper and deciding which is right for you. 

Density – In general the higher the density of the foam within your topper the more support it will provide and the more expensive it will be. For an every night sleeping option we generally do not recommend a topper that has less than a 4lb density. 

Material – Decide what you need out of your topper and which material will provide that for you. Memory foam has unbeatable pressure relief while latex foam is natural and has hypoallergenic properties as well as great support and bounce. 

Thickness– Mattress toppers vary in thickness from 1-4. A 1″ topper will obviously be much cheaper than a 4″ topper but do not let that coax you into purchasing a thin topper, as this will likely not achieve the comfort goals that you are looking for from your topper. We usually recommend at least a 3″ topper to feel any sort of benefits, while. 2″ topper may be sufficient for lighter individuals

Price – Price can vary drastically form mattress toppers and in general it is important to follow the golden rule. “You get what you pay for”. his is especially true with mattress toppers as they are all foam and the difference between a high priced topper and a low priced topper is usually just the quality of foam that they are providing, even though they may look exactly the same.

Manufacturing location- We always recommend purchasing sleep products that are made in the USA. Some of the foams coming out of Asia do not meet the quality standards that companies have here in the US. 


Latex vs memory foam cal king mattress toppers:

If you are trying to decide between latex and memory foam you may be wondering what the difference is. Here is an explanation of each that can give you an idea of what benefits they each provide. 

Memory foam: Memory foam is going to be best for anyone looking for additional comfort that provides pressure relief while also supporting and cradling the body. Memory foam conforms to your body and its curves in a way that no other foam can. If you have never tried memory foam before it can take a little getting used to as it feels different than any other foam on the market. 

Latex: Latex has world class rebound and is great at support and bounce-back. Latex also provides top of the line pressure relief and is a natural material, made without any chemicals or artificial materials. Latex is hypoallergenic and usually comes with an organic cotton cover, which is great for anyone who may be sensitive to different fabrics or materials. 

What is the most supportive cal king mattress topper for a heavier person?

If you are a heavier individual who is looking for a mattress topper that will support your body weight and not break down then you will want to ether choose a memory foam or latex topper. Make sure the topper you choose has at least a 4lb density and is 3-4 inches in thickness. Since you are sleeping on a cal king it probably means there are 2 of you, which makes the weight load even heavier and is all the more reason to get a topper that can support higher weight loads. 

Is a thicker mattress topper better?

In general a thicker mattress topper will provide more support for your body, however, the most important factor to look at is foam density and ILD. This will let you know the quality of foam and how supportive it really is. In general, we suggest purchasing a topper form an American made company, as many of the Asian manufactured products are lower quality foams with lower densities and occasionally chemical additives. 

What to do with your old mattress topper?

When you purchase a mattress online you are left to find a way to get rid of your old one. Luckily “A Bedder World” has mattress disposal services throughout the country.
