Frequently Asked Questions
What is the difference between a King mattress and a California King Mattress?
The main difference between a standard king mattress and a California king mattress is the measurements of the width and length. California kings are longer and narrower than standard kings measuring 72 inches by 84 inches. A standard king bed measures 76 inches by 80 inches.
What are the benefits of purchasing a California King Mattress?
If a standard size king bed does not fit well in your bedroom, a California King is a good option. California King mattresses are also appealing for very tall individuals.
What is the difference between a latex mattress and memory foam in a mattress?
Natural latex mattresses are made from the sap from a rubber tree, while memory foam is a synthetic material made from a petrochemical product.
Memory foam is made from a dense material that conforms to your body. Memory foam can off-gas chemical odors and compounds which may pose concern and have less heat disbursement than natural latex. Natural latex is more responsive and comfortable for most people. Some mattresses are made from 100% latex, some have a layer of latex, some are made from memory foam and others are constructed with a combination of these materials in different layers.
Do latex mattresses smell?
Like with many new products, latex mattresses do have a particular smell that some people may notice. 100% natural latex does have a short-lived small that is the natural scent of the hevea milk (rubber tree sap) that some describe as “sweet”, “nutty,” or “somewhat like vanilla”.
