What does a mattress with free trial mean?

This means that once you buy your mattress, you have up to 365 nights to sleep and test it out at home. Getting used to a new mattress takes a little bit of time, that’s why mattress companies are giving the option to try out a mattress for 365 nights (or 200 nights with Emma). This is a full year, so you can test it during all four seasons and see if it sleeps hot or not. 

If by that time you’re not satisfied with the mattress, simply contact the company and they’ll arrange a free pick up, and will then give you back a full refund. Just make sure you have kept the receipt, so you can show it as proof of payment.

The trial period starts on the date the mattress is delivered to your home. You don’t have to keep the box or any other packaging that came with the mattress.

Are the returns free?

The delivery and returns are free for UK mainland. However if you live in a remote UK postcode area, please double check with each company if they charge any delivery or return fee. 

What happens to the returned mattresses?

Every mattress company disposes of them differently, they might recycle them or give them away to charity. For example, Emma says that the very few mattresses that are returned as part of their 200 day trial are donated to the charity British Hearth Foundation. 

Some companies may choose to inspect and clean returned mattresses, and sell them again as refurbished at a lower price. However, if you buy a refurbished one their warranty will be much shorter (usually 1 year) and the sleep trial will be shorter as well (just 30 days).

Can you use 0% Financing?

All the companies on this list offer 0% financing. Emma and Simba have partnered with DivideBuy, while Nectar and Dreamcloud work with Klarna to offer 0% financing on all their mattresses. You can spread your payment across monthly instalments, and choose instalment options from 3 to 12 months. With Klarna you can pay for your mattress within 30 days of placing the order, or pay for your order in 3 installments. 

If you decide to return a mattress, which was bought with 0% financing and the trial period has not passed yet, you’ll be refunded the amount you have already paid. Your bill with be cancelled, and there won’t be any outstanding payments that need to be made.
