What are the best mattresses for motion isolation?

Here’s a list of the best mattresses for motion isolation, covering what motion isolation is, how materials and construction affect it, and ways to test it yourself.

Koala Mattress

Why Koala Mattress is a good choice

• Kloudcell™ foam absorbs movement, reducing transfer across the bed.
• Zero Disturbance® technology limits partner disturbance at night.
• Partner Preference option allows custom firmness for each side.

The Koala Mattress is designed to reduce motion transfer, which is crucial for those who share a bed and want to avoid sleep disturbances caused by movement. Its all-foam construction, including Kloudcell™ foam and a 3-Zone Support Layer, helps absorb motion and distribute weight evenly across the surface. Foam mattresses and hybrids with individually wrapped coils generally provide better motion isolation than traditional innerspring designs. To evaluate motion isolation, simple tests like placing a glass of water on the mattress and observing for ripples during movement can be helpful, as can taking advantage of in-store or sleep trial periods.

TEMPUR PRO® Medium

Why TEMPUR PRO® Medium is a good choice

• TEMPUR® material adapts to your body, dampening motion instantly.
• Advanced pressure relief prevents movements travelling across the mattress.
• Ideal for light sleepers sensitive to partner movement.

Motion isolation describes how well a mattress absorbs movement, so one person’s motions aren’t felt on the other side—an important feature for those sharing a bed. Materials like memory foam, as used in the TEMPUR PRO® Medium, are known for effectively reducing motion transfer compared to traditional innerspring designs. The TEMPUR® Advanced Material found in this mattress adapts to body shape and weight, which can help minimise disturbances caused by a partner’s movement. To evaluate motion isolation, try placing a glass of water on the mattress and watch for movement while pressure is applied elsewhere, or consider a sleep trial.

SEALY Posturepedic Acclaim

Why SEALY Posturepedic Acclaim is a good choice

• AlignSupport™ coils respond independently, minimising motion transfer.
• Memory foam layers absorb energy from movement effectively.
• Edge support keeps the whole mattress stable, reducing disruptions.

Motion isolation describes a mattress’s ability to limit the transfer of movement, helping reduce sleep disturbances for those sharing a bed. Materials such as memory foam and hybrid designs with individually wrapped coils typically absorb and minimise motion transfer more effectively than traditional innerspring mattresses, which can transmit movement across the sleep surface. To evaluate motion isolation, practical methods include placing a glass of water on the mattress and observing any movement when pressure is applied elsewhere. In-store trials and retailer sleep trials also allow users to personally assess how well a mattress controls motion and supports uninterrupted rest.

ECOSA Pure Mattress

Why ECOSA Pure Mattress is a good choice

• Micro-coil and latex layers limit partner movement across the bed.
• Adjustable firmness lets you choose the most stable setting.
• Hybrid design offers both support and effective motion isolation.

The ECOSA Pure Mattress is a hybrid option designed with motion isolation in mind, which is beneficial for those sharing a bed, as it limits the transfer of movement across the surface. Its construction includes micro-coils and latex comfort layers, contributing to both breathability and support. While the micro-coil layer offers increased airflow and comfort, it may allow slightly more motion transfer than all-foam models, but remains effective for most sleepers. To assess motion isolation, practical tests such as the glass of water method, as well as in-store or sleep trials, can help determine performance for individual needs.
