Product Questions

Does Kingaru sleep hot?

Kingaru mattresses are specifically designed to sleep cool. We put a lot of R&D into how Kingaru performs throughout the night. Our mattresses use a breathable comfort foam to offset the memory foam layered beneath it. This construction helps keep things nice and breezy and extremely comfortable.

Does the foam smell?

Any new product can have a mild scent upon unboxing. Should your Kingaru mattress have a scent, it will dissipate in a few hours in a well-ventilated room.

Are there chemical fire retardants in the mattress

The Kinagru mattresses do not contain any flame retardant chemicals. Our flame retardant is a proprietary woven silica sock that’s just under the cover. In the event of a fire, the sock melts on itself and suffocates the oxygen needed for the fire to burn.

How thick is the Kingaru Mattress?

The Kingaru mattress is 25 cm thick.

Do you produce custom size mattresses?

Yes, we do! The Kingaru is available in custom size. Prices are on request.

Does the Kingaru mattress transfer movement?

Kingaru mattresses provide more movement isolation than a traditional spring mattress — some customers have even said their Kingaru saved their marriage! We don’t suggest jumping on the bed with a glass of red wine on the other side, but we designed the sleep surface to strike a perfect balance between motion isolation and a comfortable bounce. If your partner is more than 15cm away, you won’t feel or hear their tosses and turns.

Can I roll up the mattress like an airbed?

Kingaru mattresses are intended for permanent use. Once out of the box, a mattress will not recompress back in or roll up like an airbed. If you aren’t using a Kingaru as your primary mattress, we recommend storing it fully opened, on the floor. It can also be temporarily stored on its side.

Will the mattress form a hole in the middle after a while?

Kingaru mattresses are not designed to form a hole — in fact, all the foam we use retains bounce and remains supportive night after night, so there won’t be a valley like other mattresses. To ensure that your Kingaru mattress performs as it should, we just ask that you set it up on a firm, flat surface. Still concerned? It’s actually covered in our 10-year warranty.

Can I use a metal frame?

With any foam mattress, you want as much firm support directly applied to the mattress as possible. Therefore, a simple metal frame with thin support beams will not hold up very well, but one with unyielding, thick wooden slats will work fine. If you are considering using a metal frame, we suggest placing a piece of plywood on the top of the metal to close up the unsupported surface. If you have any questions about a specific setup, our Customer Experience team is ready to help.

Payment and service

What is the return process?

If you decide that your Kingaru Mattress isn’t right for you within 100 nights, please contact us and we’ll process a full refund once we receive them back at our facility.

What happens to my returned products?

We never resell a used mattress. Returned Kingaru mattresses will be donated to a local charity.

What does the 100 nights trials mean?

Dream on your mattress for 100 nights from the day you receive them. This post-purchase, risk-free 100-night trial serves as our return policy. If you decide your Kingaru mattress isn’t for you, you can send it back: your original form of payment will be refunded 100 percent.

Company & service

Do you have a showroom?

Not currently. However, we are developing pop-up stores and experience centers.

Where can I test the mattress?

At this moment only after ordering. But because of our 100 night trial it's fully risk-free. We are working on getting pop-up stores up and running where people can test the mattress.

How are Kingaru mattresses reviewed and rated?

In one word: honesty. On kingarusleep.com our goal is to provide an authentic portrayal of ordering and sleeping on our products from the point of view of the customer. We ask our customers to rate our products on a scale of one to five. We don’t edit, block, or censor any of the reviews. The Kingaru reviews go further: in addition to a one to five rating, we ask customers their age and location, if they share the bed with a partner, and allow them to input how many hours of sleep they get per night. It adds some additional context to their experience, so potential customers can read the reviews of a similar sleeper. The only way to know if our products are right for you is to take advantage of our 100-night trial and sleep on it yourself. If you don’t love them, we’ll give you a full refund.

Can you explain the 10 year warranty?

Kingaru mattresses are covered by a 10-year limited warranty. In short, we’ll either repair any issue causing the mattress an indent . We also cover any physical flaw in the mattress that causes our foam layers to split or crack despite normal usage and proper handling.

How big is the box the Kingaru mattress ships in?

All Kingaru mattress sizes ship in our standard box of 50x50x110 cm and weights approximately 23kg.
