How thick of a mattress do i need?


When it comes to choosing a mattress, one important consideration is its thickness. The thickness of a mattress can greatly impact your comfort and sleep quality. But how thick of a mattress do you really need? In this article, we will explore the factors that influence mattress thickness and help you determine the ideal thickness for your specific needs.

Factors Influencing Mattress Thickness

1. Sleeping Position: Your sleeping position plays a significant role in determining the ideal mattress thickness. Different sleeping positions require varying levels of support and cushioning. For example, side sleepers often prefer a thicker mattress to provide adequate pressure relief for their hips and shoulders, while stomach sleepers may opt for a thinner mattress to maintain proper spinal alignment.

2. Body Weight: Your body weight also affects the ideal mattress thickness. Heavier individuals typically require a thicker mattress to prevent sinking too deeply into the mattress, which can lead to discomfort and inadequate support. On the other hand, lighter individuals may find a thinner mattress more comfortable as it provides sufficient support without excessive firmness.

3. Personal Preference: Ultimately, personal preference plays a crucial role in determining mattress thickness. Some people prefer the plush feel of a thicker mattress, while others prefer the firmer support of a thinner one. It’s important to consider your own comfort preferences and sleep needs when choosing the thickness of your mattress.

Common Mattress Thickness Options

1. 6-8 inches: This is the thinnest mattress option available and is often found in budget or children’s mattresses. While these mattresses may be suitable for occasional use or for individuals with lighter body weight, they may lack the necessary support and durability for long-term use.

2. 10-12 inches: This is the most common mattress thickness range and offers a good balance of comfort and support for the average sleeper. These mattresses typically provide adequate cushioning and support for various sleeping positions and body weights.

3. 14-16 inches: These mattresses are considered thicker and are often preferred by individuals who enjoy a plush, luxurious feel. They offer extra layers of cushioning and are suitable for those who prefer a more substantial mattress.

4. 18 inches or more: These ultra-thick mattresses are less common but can provide exceptional comfort for those who prefer a high-profile bed. They often include additional layers of foam, pillow tops, or Euro tops for maximum cushioning and support.

Considerations for Special Cases

1. Adjustable Beds: If you have an adjustable bed, it’s important to consider the mattress thickness that will work best with your bed’s mechanisms. Thicker mattresses may limit the bed’s flexibility, so it’s essential to choose a mattress that can bend and adjust without compromising its structural integrity.

2. Platform Beds: Platform beds typically have slats or a solid base that supports the mattress directly. In this case, the thickness of the mattress is less critical as long as it provides adequate support. However, you may want to consider the overall height of the bed when choosing the mattress thickness to ensure it aligns with your desired aesthetic.


The ideal thickness of a mattress depends on several factors, including your sleeping position, body weight, and personal preference. While there are common thickness options available, it’s crucial to consider your specific needs and comfort preferences when making a decision. By taking these factors into account, you can choose a mattress that provides the right balance of support and comfort for a restful night’s sleep.
