Question 1

Extra firm vs firm mattress — what is the difference?

Accepted Answer

A firm mattress rates 7-8 on a 10-point firmness scale. It provides solid support with minimal sinkage but still includes a measurable comfort layer that provides some cushioning. An extra firm mattress rates 9-10 and has little to no comfort layer — you are sleeping directly on a rigid support system with almost no give. Most people who say they want "extra firm" are actually well-served by a 7-8 firm. True extra firm (9-10) is appropriate only for dedicated stomach sleepers, very heavy individuals, or those with specific therapeutic requirements.

Question 2

Who needs an extra firm mattress?

Accepted Answer

Extra firm mattresses are appropriate for a narrow but specific group: dedicated stomach sleepers who require maximum hip support to prevent lumbar hyperextension; very heavy sleepers (250+ lbs) who find firm mattresses compress to a medium feel under their weight; individuals with specific spinal conditions where a maximally firm surface has been recommended by a healthcare provider; and those transitioning from floor sleeping who need a firm, flat surface. For most back sleepers, a 7-8 firm is sufficient.

Question 3

Is extra firm good for back pain?

Accepted Answer

Extra firm is beneficial for back pain only in specific circumstances. For stomach sleepers, extra firm prevents the hip sinkage that causes lumbar hyperextension — a genuine source of back pain. For some very heavy back sleepers where firm mattresses still compress too much, extra firm may help maintain spinal alignment. However, extra firm is not a universal back pain remedy. For most back pain sufferers who sleep on their back, a firm (7-8) or medium-firm is more appropriate. For side sleepers with back pain, extra firm is typically the wrong choice.

Question 4

Is extra firm mattress good for heavy sleepers?

Accepted Answer

Yes — for sleepers in the 250+ lb range, an extra firm mattress often delivers what a firm mattress cannot. At higher body weights, the compression force on a mattress is significantly greater. A mattress that rates firm (7-8) may compress to a medium feel for a 280-lb sleeper, while an extra firm (9-10) provides the actual resistance needed to maintain proper support and spinal alignment. Extra firm hybrids are particularly well-suited for heavier sleepers.

Question 5

Will an extra firm mattress hurt my shoulders or hips?

Accepted Answer

It depends on your sleep position. For stomach and back sleepers, no — extra firm distributes body weight across the flat support surface without creating significant pressure points. For side sleepers, yes — extra firm does not contour to accommodate the shoulder and hip protruding from the side profile, which creates hard pressure points. If you sleep on your side, extra firm is not the right choice and will likely cause shoulder and hip pain.

Question 6

How long does an extra firm mattress last?

Accepted Answer

Extra firm mattresses tend to have the longest lifespan of any firmness tier because their dense materials and minimal comfort layers are the least prone to wear-related softening and body impressions. A quality extra firm hybrid from a major brand can last 10-15 years with normal use. The coil system remains functional far longer than the comfort layer on plush or pillow top mattresses. Using a solid foundation (not an old box spring) extends mattress life further.

Question 7

Is an extra firm mattress uncomfortable?

Accepted Answer

It depends entirely on whether it matches your needs. For a dedicated stomach sleeper or 280-lb back sleeper, an extra firm mattress is the most comfortable option available — it provides the support they need to sleep pain-free. For a side sleeper or a 150-lb back sleeper, an extra firm mattress will feel hard, unforgiving, and likely cause pressure point pain. Firmness is not universally "comfortable" or "uncomfortable" — it depends on matching the right firmness to the right sleeper. Our in-store specialists can help determine if extra firm is right for you.

Question 8

Can I return an extra firm mattress if it is too hard?

Accepted Answer

Yes. Every mattress at LA Mattress Store comes with a 120-night sleep trial. We ask that you sleep on it for at least 30 nights before making a final decision. If after 30 nights the extra firm mattress is too hard for you, contact us for a free exchange or return — no restocking fee. Extra firm is a specific preference, and we would rather help you find the right firmness than leave you uncomfortable.
