Not just filler

Not Just Filler: The Difference Between Springs, Latex, and Foam

With a surge in mattress options, it can be a challenge to understand the difference between all of the different types of beds out there. Truth be told, not every mattress is perfect for every sleeper, so we’ve compiled the pros and cons of the most common materials used in beds today.

From your grandma’s innerspring mattress to more modern options like latex and memory foam, each of these comes with their own set of advantages and drawbacks. Taking into consideration qualities like durability, comfort, and convenience of purchase, here’s the run down of how the top beds compare to one another.


This is one of the most common mattress types, and typically represents the majority of the inventory that you would encounter while shopping at a traditional brick-and-mortar mattress store. These mattresses have been around for decades, and are characterized by an internal structure of steel coils that provide firmness and a “springy” resistance.


Firmness: These beds are known for their firmness and bounce and many options that can be tailored to sleepers’ individual preferences.

Availability/Cost:  Innerspring mattresses are widely available and can be purchased at almost any big-box mattress store.  With a range of different options, these mattresses start at very affordable price-points.


Durability/Longevity: According to Sleep Like the Dead, within three years of ownership, over a quarter of owners report sagging and deterioration of their mattress.

Pressure-point relief: Innerspring mattresses lack the conforming quality of memory foam and latex beds, resulting in noticeable pressure-points and uneven distribution of sleepers’ weight.


These beds have been gaining popularity, especially as products have been introduced that claim to be “green” or environmentally friendly. Latex beds are not widely available in stores, and come in a variety of options with varying claims around support, breathability and longevity.


Comfort/pressure-point relief: According to Sleep Like the Dead, Latex beds score well in their conforming ability, and typically provide a positive combination of softness and support.


Cost: The average price of an all-latex mattress runs for about $1,900, which skews considerably higher than other beds with similar features.

Assembly: Most Latex beds require in-home assembly, which involves stacking layers inside a cover and then zipping closed.

Heat-retention: Latex mattresses have been reported to sleep warm, causing discomfort for some consumers.

Misinformation: Latex mattress vendors often lack transparency to consumers when explaining their products. For example “all natural” latex beds only require to be made of 50% natural materials, which is rarely cited by manufacturers and can create confusion for consumers.

Memory Foam

Like latex beds, memory foam mattresses are available in multiple configurations and can be composed of different combinations of materials. Increasingly, memory foam is becoming a top choice among young consumers that want the convenience of mattress delivered to their doorsteps, and warrantees to protect their investments into the distant future.


Comfort/pressure-point relief: Sleep Like The Dead research cites that owners of memory foam beds report high overall satisfaction, as these beds have optimum conforming and support qualities, proven to reduce tension and back-pain, and provide relief to pressure points. 

Convenience: These beds are available to consumers through a variety of different channels. Somzi mattresses can be purchased online and are delivered in one day with a 100 night trial period.  

Lifespan/Durability: Memory foam mattresses have an average lifespan of 7 years, considerably longer that spring and latex beds. Somzi mattresses are engineered to last for at least 10 years, and are backed up with a warranty to cover that amount of time.


Heat Retention:  While Somzi beds are engineered with a proprietary BluWave gel  layer that keeps sleepers cool at night, other memory foam mattresses have been reported to retain heat and sleep warm.
