12 vs 14 Inch Mattress: Which Thickness Is Right for You?

Choosing between a 12-inch and 14-inch mattress? A 14-inch mattress usually comes with a higher price. But are the 2-inch differences really worth it for the price? In this article, we'll give you a detailed comparison of these two models and help you make the right choice.

Where Do the Extra 2 Inches Go?

A mattress's total thickness is the combined height of its different layers. Depending on the design, a mattress may include a cover, comfort layers, transition layers, a support core, and a base layer.

That means the extra two inches in a 14-inch mattress can be used in different ways. A manufacturer may add more cushioning to the comfort system, increase the thickness of a transition layer, build a more substantial support structure, or combine several of these changes.

For example, a thicker comfort system can provide more room for your shoulders and hips to sink into the mattress. A thicker transition or support system can change how deeply you sink and how the mattress responds to your weight.

So, mattress thickness should not be viewed on its own. Two 14-inch mattresses can have very different constructions and feels, just as two 12-inch mattresses can.

12-Inch Mattress Pros and Cons

Pros of a 12-Inch Mattress

• A good balance of comfort and support: A 12-inch mattress has enough room for comfort and support layers without becoming excessively tall, creating a balanced feel without feeling too firm or cushioned.
  
• A versatile choice for many people: At 12 inches, a mattress can accommodate a wide range of constructions and firmness levels, making it a common choice for different types of sleepers.
  
• Easier to move and store: Compared with a 14-inch mattress, a 12-inch model is generally less bulky and easier to handle during delivery, setup, or a future move.
  
• Create a comfortable bed height: A 12-inch mattress is tall enough to add a good amount of height to the bed without making the sleep surface too high.
  
• More affordable: When comparing mattresses from the same brand, a 12-inch model will often cost less than the corresponding 14-inch version.
  

Cons of a 12-Inch Mattress

• Less room for comfort system: A 12-inch mattress has a limited amount of space for its comfort, transition, and support layers. Compared with a 14-inch mattress, there may be less room for multiple or especially thick cushioning layers.
  
• May not provide as much deep contouring: Sleepers who prefer a pronounced "sinking in" sensation may find a 12-inch mattress less enveloping than a thicker model with a more substantial comfort system.
  
• May offer less support for some heavier sleepers: A 12-inch profile can work well for many adults, but heavier sleepers may benefit from a thicker comfort system and a more substantial support core, depending on the mattress construction.
  

14-Inch Mattress Pros and Cons

Pros of a 14-Inch Mattress

• More room for cushioning and support layers: A 14-inch profile gives manufacturers more space to use thicker comfort layers, transition materials, or a more substantial support core.
  
• Deeper pressure relief: The additional space can be used in the comfort layer, providing more cushion on your shoulders and hips, which is particularly useful for side sleepers.
  
• More room for substantial support: When those additional inches are allocated to the support core or transitional layers, they can provide more structural depth. This can be useful for sleepers who place more load on the mattress.
  
• A more plush feel: When the additional height is used for thicker comfort layers, a 14-inch mattress gives you a more cushioned, enveloping feel that appeals to sleepers who prefer a plush sleep experience.

Cons of a 14-Inch Mattress

• Heavier and harder to move: More material generally means more weight. A 14-inch mattress can be more difficult to lift, rotate, move between rooms, or take with you when relocating than a thinner mattress.
  
• Usually costs more: A taller mattress may require additional foam, coils, padding, or other materials, which can increase its manufacturing cost and, ultimately, its retail price.
  
• Can make the bed too tall: When combined with a tall bed frame or foundation, a 14-inch mattress can push the overall bed height higher than expected. This may make getting into and out of bed less convenient for some sleepers.
  
• May require deeper-pocket sheets: The thicker profile can make sheet fit more important. Depending on the mattress and sheet dimensions, standard sheets may not provide enough room around a 14-inch mattress, so deep-pocket sheets may be necessary.
  

12 vs. 14: Which One Makes More Sense for You?

Haven't decided on which mattress thickness yet? Here's a quick guide that might be helpful:

Your Situation	12-Inch	14-Inch
Back sleeper	✓ Better fit for balanced support	Consider if you prefer a plusher feel
Stomach sleeper	✓ Better if you need firm support and limited sinkage	Consider only with a supportive construction
Side sleeper	✓ Good with sufficient comfort cushioning	✓ Better if you want deeper cushioning
Combination sleeper	✓ Easier balance of cushioning and responsiveness	Consider if you prefer a plusher feel
Under 230 lbs.	✓ Often sufficient	Consider if you want more cushioning
Over 230 lbs.	Consider if construction has adequate support	✓ More room for comfort and support layers
Sleeping with a partner	✓ Works for many couples	Better when combined weight or cushioning needs are higher
Prefer medium to medium-firm	✓	Can work, but thickness alone doesn't determine firmness
Prefer plush/deep contouring	Can work with the right comfort system	✓ More room for thicker cushioning
Tall bed frame/foundation	✓ Easier to keep total bed height manageable	May make the bed too tall
Low-profile bed frame	May feel relatively low	✓ Can create a more substantial overall bed height
Limited mobility/difficulty getting into bed	✓ Easier to control total bed height	Consider only if the resulting total height remains comfortable

Bottom Line

A 12-inch mattress and a 14-inch mattress can both be excellent choices. The two-inch difference matters, but it does not tell you everything about how a mattress will feel or perform.

A 12-inch mattress can offer plenty of room for comfort and support while keeping the overall profile more manageable. A 14-inch mattress gives manufacturers more space to add cushioning, transition material, or other layers, which can be useful if you want a deeper or more substantial feel.

In the end, the best thickness is not necessarily the one with more inches. It is the one whose construction, feel, and overall height make sense for the way you sleep.
