Why Trust Us

Ultra plush and plush mattresses might draw you in with their soft to the touch feel, but does that mean they are the best choice for a full night’s sleep? If you lie down for any considerable length of time on a soft mattress, you will likely find yourself sinking into its plush surface, and that might not be great for your body. For sleepers who wake up with more aches after spending the night on a pillow-y mattress, it might be worth exploring a medium, firm, or extra firm mattress to give you better support.

In this guide, we will explain seven reasons not to get a soft mattress, plus recommend four of our favorite firm mattresses.

7 Reasons Not to Get a Soft Mattress

 A woman sleeping on her side on a mattress

The debate between firm vs soft mattress benefits is ongoing, but here are some reasons not to choose a soft mattress. It is important to keep in mind these potential disadvantages of memory foam mattresses. For instance, memory foam is soft and contours to your body, which can offer support for your joints, but there are plenty of memory foam mattress pros and cons. One major pro is motion isolation. If you or your partner tend to toss and turn, foam is a great option.

With that in mind, here’s the not-so-good news when it comes to plush mattresses.

❌ Reason 1: Soft mattresses do not last as long

The softer materials that make up ultra plush mattresses break down more quickly. That’s because mattresses experience a lot of compression, and when a mattress’s structure is soft, it tends to compact quicker than other materials such as latex or coils. If you’re looking for a mattress that will last you for years, avoid extra soft mattresses.

❌ Reason 2: Soft mattresses tend to trap more heat

Because foam and other contouring materials fill in close to your body, there is not as much airflow between the surface and the body. As a result, heat gets trapped. If you tend to be a hot sleeper, look for a mattress that prioritizes temperature control and air circulation.

❌ Reason 3: Some soft mattresses aren’t so healthy

Memory foam mattress health concerns include off-gassing. Look out for mattresses with safety certifications, like CertiPUR-US. On the other end of the spectrum, foam mattress side effects include varying quality and sinking. This is a concern because irregularities in the surface of a mattress can cause spinal misalignment, resulting in back, hip, and shoulder pain.

 Because memory foam mattresses are so widely available on the internet, there is bound to be a varying level of quality on the market.

❌ Reason 4: Soft mattresses are not ideal for couples

“Which type of mattress is best?” is a question to consider not just as an individual, but for you and your partner to answer together. A medium or firm mattress is going to be the best medium. You and your partner may not share the exact same preferences, but you are more likely to find common ground if you avoid the extremes of an extra soft or extra firm mattress.

❌ Reason 5: Soft mattresses are not ideal for back or stomach sleepers

One of the benefits of a firm mattress is that the surface is ideal for back and stomach sleepers. Again, this goes back to spinal alignment. The less a mattress sinks, the lower the chance your body’s posture will become misaligned. This is particularly important for stomach sleepers since the sleep position is the most vulnerable to bad posture.

What about a firm or soft mattress for side sleepers? Side sleepers lighter in weight might find a soft mattress comfortable because they aren’t as likely to sink into it. Side sleepers can also benefit from the support of a firm mattress.

❌ Reason 6: Soft mattresses sink easily

Stomach and back sleepers should avoid soft mattresses at all costs. Even for side sleepers, you might feel like your mattress is swallowing you up. Softness sounds comfortable in theory, but your body likely needs more support. Sinking into your mattress can worsen snoring. Also, keep in mind your and your partner’s weight. Heavier sleepers are not suited for soft mattresses.

❌ Reason 7: Soft mattresses can lead to improper spinal alignment, back or joint pain, and stiffness

Sleepers in every position need support for their spine, but back and stomach sleepers need a firmer surface to ensure their hips and lower back stay at the same level as the rest of the body. Look for mattresses that combine different material types to offer ergonomic comfort and support.

Firm Mattress Benefits

For all of these reasons, we recommend exploring the possibilities of a firm mattress. With the motion control of a firm mattress, you don’t have to worry about bothering your partner when you stir during the night, and you also get to enjoy the support and comfort of your mattress without sinking into it.

Mattresses that are extra firm offer very similar advantages, but make sure to ake the time to test out an extra firm mattress first. It is a good rule of thumb to avoid extremes with mattress comfort.
