Firmness info–

The Koala Calm As mattress has a double-sided comfort layer that you access by unzipping the cover, and flip this layer over. You can choose between medium-firm support and firmer support. Koala recommend trying the medium-firm default side first. The Calm As mattress is the firmest, the Koala in the middle, and the Soul Mate is not quite as firm. The same order applies when using the softer side.

FAQs

Sealy Posturepedic

What are the different levels of Sealy mattresses?

The Essential line, the most affordable, delivers the basic comfort and support Sealy is known for. The Performance line upgrades this with Posturepedic Technology for enhanced support particularly in crucial areas. The Premium line builds on this, adding sleep-enhancing technologies to the mix for a deep, relaxing sleep. Finally, the Posturepedic Plus line takes comfort to another level with more targeted back and core support. It uses advanced engineering and high-quality materials to target support for each area of the body. Choosing the right line depends on personal comfort preferences, budget, and individual sleep needs.

Do Sealy Posturepedic mattresses have pocket springs?

No, Sealy Posturepedic mattresses do not utilise pocket springs. Instead, they employ an innerspring system, a network of interconnected springs. While this design offers traditional feel and robust edge support, it lacks the motion isolation quality provided by pocket spring systems, where each spring is individually encased. The ideal choice depends on an individual's sleep preferences and needs.

Can Sealy Posturepedic mattresses be flipped?

That's correct, Sealy Posturepedic mattresses are designed as one-sided or no-flip mattresses. To ensure even wear and prolong the lifespan of the mattress, you should rotate it 180 degrees periodically. This involves turning the mattress so that the head end becomes the foot end, helping to distribute the wear more evenly over the surface of the mattress. However, you won't need to flip the mattress over as its design includes specific layers for optimal comfort and support.

Koala Calm As

Is Koala calm as worth it?

The Koala Calm As mattress, known for its comfort, support, and cooling features, is competitively priced and could be a worthwhile choice if it aligns with your sleep preferences and needs. However, individual comfort varies, so consider your personal sleeping habits and any physical conditions before purchasing.

How long will a koala mattress last?

While it's challenging to provide an exact lifespan for the Koala Calm As mattress since it's a relatively new product, we can look at general guidelines and the quality of its construction. Mattresses typically last between 7-10 years, with high-quality ones potentially exceeding this range. The Koala Calm As mattress has been recognized for its quality, receiving the 'Product of the Year' award in the mattress category for 2022 and being CHOICE® recommended. It's a well-constructed product that should provide good durability, but actual lifespan can vary depending on factors such as usage and care. Regular rotation, for instance, can help extend the life of a mattress.

Can the Koala Calm as mattress go on slats?

Yes, the Koala Calm As mattress can be placed on slatted bed frames. However, it's important to ensure that the slats are not too far apart. As a general rule, the gap between slats should be no more than 3 inches (or about 7.6 cm) to provide adequate support and prevent sagging. If the slats are too far apart, it may affect the mattress's support and potentially its lifespan. Always make sure your bed frame is in good condition and provides sufficient support for your mattress.
