Better sleep

Sleep research at the heart of our development

Our long‑term work with sleep researchers has taught us exactly what contributes to proper recovery. These insights shape every detail of our beds, ensuring that materials and ergonomic features work together for truly restorative sleep. Our goal is clear: to give you sleep that truly improves your life.

Check this when trying a new bed

Do you have a favourite position when falling asleep? Try the bed in that same position. If you prefer to sleep on your side, the soft shoulder zone should help your shoulder to sink into the mattress, and the firmer should give the right support for your hips. With Wonderland’s adjustable hip zone you can fine-tune the firmness and personalize the support entirely to your needs.

What happens when we sleep?

Good sleep is one of the most important factors for both physical and mental health. When we fall asleep, the body initiates processes that affect everything from concentration and memory to the immune system, muscle tension, and stress levels. Research also shows that sleep works like a “washing machine” for the brain. Waste products that accumulate throughout the day are flushed out, allowing both the brain and the body to prepare for a new day.

Which sleeping position is most common?

For several years, we have conducted large sleep surveys, and the results are clear.
96% have a preferred sleeping position, and 75% choose to sleep on their side. Side-sleeping also becomes more common with age. With knowledge about sleeping positions and how the body recovers best, we can develop beds that keep the body in an optimal position throughout the night.

How much sleep do we need?

Sleep needs vary from person to person, but general recommendations state that adults need 7–9 hours of sleep, while adolescents need 8–10 hours each night. Some manage with slightly less, while others need more to wake up refreshed and ready for a new day.

Do we sleep deeply all night?

Sleep consists of several stages that repeat throughout the night. When we fall asleep, we quickly enter deep sleep, the most restorative phase where the body recovers, renews itself, and strengthens the immune system. After this, we transition into lighter sleep and REM sleep, where the brain processes impressions, emotions, and learning. The interaction between these stages helps us wake up feeling more rested – both physically and mentally.

Sleep research as a foundation for better beds

To understand the importance of sleep and how it can be improved, Wonderland has collaborated with leading sleep researchers for over 20 years. Our product development is based on insights into:

• How the sleep stages affect sleep quality.
• How the body can remain as still as possible during the first deep sleep stage.
• What level of comfort, support, and pressure relief the body needs for better recovery.
• How ventilation, moisture management, and materials influence recovery and sleep quality.

Sleep that improves your life

Since 1969, Wonderland’s vision has remained the same: to contribute to a world that sleeps better. For us, sleep is about far more than a good bed. It’s about quality of life, energy, presence – and about being able to stand stronger in everyday life. That’s why we make our beds with one clear goal: to give you sleep that truly improves your life.

Why we choose to sleep on our side

Sleeping on your side is perceived by many as calming. It’s a position that can resemble the fetal posture and creates an intuitive sense of security. At the same time, lying on your side offers better ergonomics. The spine maintains a more natural, pressure‑relieving alignment that reduces muscle tension. Recent research also shows that the brain’s “washing system” – the mechanism responsible for clearing out waste and toxins – works more efficiently when we sleep on our side. These findings suggest there may be a biological reason why so many naturally prefer this sleeping position. Quite simply, the body chooses what feels best on its own.

What your body needs from your bed

When you sleep on your side, your body needs a bed that allows your shoulder to sink naturally into the mattress while the heavier hip area receives the right amount of support. When the spine stays aligned, you achieve a more relaxed and ergonomic position – and a deeper, more restorative sleep.

Why Wonderland is the perfect match

Since most of us prefer to sleep on our side, we have designed an optimal combination of soft and supportive zones to give you maximum comfort and improved sleep quality. Several of our models also feature an adjustable hip zone, allowing you to fine‑tune the firmness and personalize the support entirely to your needs. And with our unique zoning and suspension system in several layers, Wonderland’s beds will provide even better sleep.

How many zones are ideal?

It’s not about the number of zones, but about the right zone design. Wonderland’s ergonomic zone system gives you deeper relief, better sleeping posture, improved sleep quality and a personalized comfort – exactly where you need it most.

Perfect for side sleepers

Since 75% of us prefer sleeping on our side, all our beds feature a soft shoulder zone that allows the shoulder to sink naturally and avoid pressure points. The shoulder area accounts for only about 25% of your body weight and therefore needs help to sink deeper into the mattress to achieve proper relief. This supports better relaxation in both the back and neck, creating the ideal conditions for deep, undisturbed sleep.

Wonderland’s adjustable hip zone allows you to fine‑tune the bed’s firmness and personalize the support entirely to your needs.

The hip area makes up about 55% of your body weight, making it the heaviest part of the body. With the adjustable hip zone, you can refine the support exactly where you need it, ensuring your hips stay aligned and don’t sink too deeply into the mattress. When everything is in balance, your spine remains straight, your muscles relax – and you enjoy deeper, more restorative sleep.

Easy adjustment for perfect comfort

You’ll find the hip zone adjustment underneath the bed. You can fine‑tune the firmness both during assembly and at any time after the bed is set up.

Softer

Place the sliders towards the middle. The bed gets softer and your hip will sink further down.

Firmer

Place the sliders towards the edges. The bed gets firmer and your hip will be placed further up.
