Frequently Asked Questions

What are the dimensions of a standard double mattress, and will it fit in my bedroom?

We offer a range of mattress sizes, from single to king, ensuring you can find the best fit for your bedroom layout. Our double mattresses are ideal for most standard bedrooms, but always check the width and length of your bed frame and available space before purchasing your new double mattress to prevent overcrowding. Consider checking our single mattress options when working with limited space, such as guest rooms.

How does the firmness level of a double mattress impact sleep quality, and which firmness is best for different sleeping positions?

Firmness plays a major role in sleep quality. Side sleepers generally benefit from a soft mattress that conforms to any figure, especially around the hips and shoulders. Back sleepers prefer a medium-firm mattress for spinal alignment, while stomach sleepers often prefer firmer options to maintain comfort and prevent sinking.

What are the warranty and return policies for your double mattress?

If you’re unhappy with the comfort level of your Koala mattress within 120 nights, you can return it and receive a full refund. And don’t forget, all our mattresses come with a 10-year warranty, so you can rest easy.
