How Thick Is a Mattress?

Mattresses consist of multiple layers, with total thickness ranging from 2 to 20 inches.
These layers are divided into two key categories:
Foundation or Base Layer
- Provides overall durability and support. An optimal thickness of 5 to 6 inches helps prevent premature wear, such as sagging.
Comfort Layers
- Contribute to spine alignment, pressure relief, and motion isolation. Balancing these layers is vital for nighttime comfort.
How To Choose Your Mattress Thickness
When selecting mattress thickness, consider the following factors:
Sleeping Position

- Back sleepers: Ideal thickness is 6 to 8 inches for proper spinal support.
- Side sleepers: Need 8 to 10 inches for hip and shoulder support.
- Stomach sleepers: Require 10 to 15 inches to support the lower back.
Body Weight
Thicker mattresses can distribute weight more evenly, which is beneficial for couples or heavier individuals while maintaining spinal alignment.
Bed Base
Mattress thickness can also influence the aesthetic and feel of a bedroom. Taller frames may call for a shorter mattress, while lower profiles can integrate seamlessly into minimalist designs.
