When shopping for a new full-size spring mattress, firmness is one of the most important factors to consider. The right firmness level can provide you with the support and comfort you need for a good night’s sleep. Here’s a comprehensive guide to help you choose the ideal firmness for your full-size spring mattress:

Factors to Consider

Sleeping Position:

Side Sleepers: Medium-soft to soft mattresses provide optimal pressure relief for shoulders and hips.

Back Sleepers: Medium-firm to firm mattresses offer proper lumbar support and spinal alignment.

Stomach Sleepers: Firm to extra-firm mattresses prevent the hips and shoulders from sinking too deeply.

Body Weight:

Light Sleepers (under 130 lbs): Medium-soft to soft mattresses cradle and support the body.

Average Sleepers (130-230 lbs): Medium to medium-firm mattresses offer a balance of support and comfort.

Heavy Sleepers (over 230 lbs): Firm to extra-firm mattresses provide ample support for increased body weight.

Medical Conditions:

Back Pain: Medium-firm to firm mattresses provide lumbar support and spinal alignment.

Neck Pain: A pillow-top mattress or a medium-soft mattress with a pressure-relieving top layer can alleviate neck pain.

Shoulder Pain: Medium-soft to soft mattresses offer pressure relief for shoulders.

Firmness Levels

Soft (1-3 on Firmness Scale): Provides a plush, enveloping feel, ideal for side sleepers and individuals who prefer a soft, cozy sleep surface.

Medium-Soft (4-6 on Firmness Scale): Offers a balance of softness and support, suitable for side and combination sleepers.

Medium (7-9 on Firmness Scale): Provides moderate firmness, suitable for back and combination sleepers who desire both comfort and support.

Medium-Firm (10-12 on Firmness Scale): A firmer option, ideal for back sleepers and individuals who prefer a more supportive sleep surface.

Firm (13-15 on Firmness Scale): Offers maximum support, suitable for stomach sleepers, heavier individuals, and those with back problems.

Extra-Firm (16-18 on Firmness Scale): Provides the highest level of firmness, typically used for heavy individuals or those with severe back pain.

Tips for Choosing

Visit a mattress store and test different firmness levels in person.

Lie down on the mattress in your preferred sleeping position for at least 10 minutes.

Pay attention to your body’s response and choose the firmness that feels most comfortable and supportive.

Consider your sleep habits, body weight, and any medical conditions before making a decision.

Remember that firmness is subjective and can vary from person to person.
