Eva vs. Koala

Eva's strength is its hybrid design. The combination of foam and springs creates a "comfy" feeling unmatched by all-foam mattresses. While some customers worried the springs would be too bouncy or uncomfortable, their fears were replaced with sweet dreams. Eva's innovative design is perfect for customers afraid to commit to an all-foam or all-spring mattress.

It's not easy choosing which Koala feature customers love best. The quick delivery service, seamless returns, and good customer service are just a few strengths. However, we were amazed at how many customers said their back and neck pain disappeared after sleeping on the Koala.

Eva's micro-springs are small enough to prevent major motion transfer. However, a spring design will always allow more movement than a full foam mattress. While several customers say their partners are not disturbed when getting out of bed, the motion will depend on your sleeping habits, total weight, and partner.

While many customers love the Koala, there are complaints about durability and firmness. Some customers say adjusting to the mattress takes time, but others found it too firm after several weeks. Others say the lack of edge support makes it difficult to get in and out of bed. Before buying this mattress, see if the company's 120-day trial period applies to your area.
