If actions speak louder than words, what does your sleep position say?

Experts theorize that sleep positions hint at your true personality. These revelations bring intimacy in the bedroom to new heights.

Sleep Positions and What They Say About You

First of all, it’s important to note that the science of bedtime personality tests isn’t black and white.

While experts are looking into the subject, the studies do not use standardized experiments. Even the terms they use might be different. Because of this, there is no existing body of science on sleep positions.

And it’s also possible that sleepers subscribe to different sleeping positions throughout the night.

That said, it’s still interesting that our personality bleeds into whether we sleep with our hands splayed across the bed or glue to our sides.

Are you ready to learn more about your true personality?

Professor Chris Idzikowski determined six personality types based on your sleep positions.

1. The Fetus or Fetal Position

Do you like to curl up into a ball when you sleep? Do you find this as the most comforting stance?

It’s one of the more popular positions, characterized by bent knees and curled torsos. And it’s a sign of a need to protect yourself—only at first.

According to the study by Professor Idzikowski, this position might be related to introversion. If you sleep in a fetal position, you might be someone with a hard shell but soft on the inside. But once you get to know someone, you may be more open and friendly.

Side sleepers will benefit from a softer mattress. It has enough give to allow your shoulders and hips to sink into a mattress. This may contribute to a straightened spine.

Cuddle with a medium or high pillow. It could keep your neck from sagging and prevent neck and shoulder pain.

Ironically, this is also the ideal sleep position for expecting mommies. Sleeping on your side can support a growing belly and may improve the flow of nutrients to your baby. A bolster between the knees can provide added comfort.

2. The Log

Asleep like a log—steady, friendly, easy-going, over-trusting.

The log sleep position is the straightened version of the fetal position. Your posture from head to toe should be as straight as a log.

Those who sleep like a log are said to be sociable, open, and popular. You might be everyone’s friend, drawing everyone’s attention with your charm.

But like a round log, you might be easily moved and swayed. Gullible.

Sleeping on your side may bring you restful and uninterrupted sleep. It may also benefit those dealing with back pain. On the other hand, it might not be ideal for those with shoulder pain.

Side sleeping may also be more comfortable for older adults. But in the same vein, it might lead to the appearance of wrinkles. Many recommend using silk or satin sheets to reduce the friction between your skin and the fabric.

Because side sleepers have higher pressure points (shoulders and hips), the best mattress would be one with multiple contouring features.

Responsive coils will adjust to your body’s natural contours. These will hold you up where you need support, and compress in areas with more weight.

3. The Yearner

Yearners sleep with their arms outstretched as if they are trying to reach for something—yearning after something.

They’re said to be open-minded, though maybe not as outgoing as those that sleep like a log. Yearners are also often described as cynical and suspicious.

And like someone that truly yearns for something, while indecisive, they stick to their decisions.

As side sleepers, yearners might yearn for a medium-soft mattress with a luxurious pillow-top layer.

Sleeping on your side might stress your shoulder muscles and lead to sore muscles in the morning. A cushy pillow top layer will envelop your pressure points in a superior support.

When it comes to firmness, softer mattresses are generally recommended. These will absorb your shoulders and hips enough to support correct spinal alignment. But it will come down to your preference.

Some like the solid support of a firmer mattress. Others prefer to be cradled in a plush haven.

4. The Soldier

Soldiers are marked by stiff postures, arms positioned at their sides. Exactly how a soldier would stand.

And true to their namesake, soldier sleepers are believed to be reserved and hold themselves and everyone else to high standards.

Soldiers might be stiff, but nothing about their muscles and mattress should be tense.

Mattresses for back sleepers should finely contour your spinal curve.

A mattress that is too firm might not cradle the lumbar area, so choose mattresses with latex layers or memory foam.

Heavier sleepers (over 130 lbs) may benefit from firmer mattresses. These can support their movements and will not sag under their weight.

Lighter sleepers (below 130 lbs) might find softer mattresses more comfortable. Being more lightweight, lighter sleepers are less likely to sink into soft mattresses.

Medium-height pillows can support the natural curve of the neck, maintaining spinal alignment from end to end.

5. The Freefall

A freefall stomach sleeper sleeps with arms spread out and legs fully extended.

Someone daring enough to freefall might be known as someone self-confident and sociable, yet jumpy and sensitive. Unlike the thrilling sport this sleep position is likened to, a freefall stomach sleeper might not be able to handle extreme situations.

Sleeping on your stomach offers the least support and forces you to awkwardly twist your neck. And sleeping on a too-soft mattress could push your neck back and lead to poor posture.

Lying on your stomach is also thought to contribute to wrinkles.

Choose a firmer mattress if you prefer to sleep on your front. It can provide support for your hips and support spinal alignment.

Some stomach sleepers opt to sleep without a pillow. It can be uncomfortable since a thick pillow raises your neck and applies pressure to your back and shoulders.

6. The Starfish

A starfish back sleeper sleeps with arms and legs splayed out on the mattress.

Just like the openness this sleep position suggests, the starfish sleeping position is often associated with friendliness and generosity.

But starfish sleepers do not like to be the star of the show, choosing to avoid too much attention.

Choose a mattress that provides shoulder, lumbar, and hip support. The best mattress for back sleepers promotes a straightened posture and cradles all the natural curves of the body.

If your mattress is too stiff and does not let your pressure points sink deep enough, it could literally leave your lumbar area hanging. Tense muscles may end up working the night shift and give you back pain in the morning.

If side sleepers especially require shoulder and hip support, back sleepers will note the importance of lumbar support.

How do sheep sleep? They sleep standing up or lying down—on a Serta mattress. Prancing around while you count them can be taxing.

Because we at Serta do not discriminate based on sleep positions, we offer some advice on how to get the best possible sleep based on your preferences.

The best mattress can support perfect posture even in your slumber. Accessories like pillows and bolsters can help support your neck and shoulders.

Your weight also comes into play when deciding on the most supportive mattress. Heavier sleepers will benefit from firmer mattresses. Lighter sleepers may appreciate the cradling support of medium-soft firmness.

On the other hand, heavy sleepers may enjoy undisturbed sleep with temperature-regulated mattresses. Light sleepers place motion isolation as the top priority.

But ultimately, the best mattress is a personal preference.

And definitely, Serta ticks all the boxes.
