Your 100-night trial begins on the day your Herdysleep mattress is delivered.

Not at all. We want you to sleep on your mattress exactly as you normally would, so there’s no need to keep it wrapped in plastic during the trial. We recommend you use a mattress protector during the trial to ensure it stays in suitable condition if you decide to return it.

If you prefer to see our mattresses before purchasing, you are very welcome to visit either the Herdy Kendal or Herdy Ambleside showrooms. Even if you try in-store first you still have the reassurance of the 100 night sleep trial. 

If you'd like to try in person first, you can visit the Herdy Kendal Shop or our Herdy Ambleside Shop

The 100-night trial applies to the Herdysleep mattress in all standard mattress sizes. It does not apply to bespoke items or made to order items.

No receipt is needed. Simply contact our customer service team and provide the details of your original order.

If you decide during the 100-night trial that your Herdysleep mattress isn’t right for you, we work with the British Heart Foundation to collect it. They take care of safe collection and professionally clean the mattress before it’s resold in their stores.

Herdysleep mattresses are proudly made in Britain, using as many British-sourced materials and home-grown skills as possible.

As Herdysleep was born in the Lake District, using responsibly sourced Herdwick fleece from friendly local sheep was an obvious choice. Herdwick wool goes into every mattress, so each night as you drift off, you’re also supporting British farmers and traditional rural livelihoods.

Alongside our natural materials, including fine cotton fibres, expert bed makers Harrison Spinks handcraft each mattress using traditional techniques such as stitching and tufting, and fill it with over 6,750 supportive Herdysleep pocket springs.

Our mattress maker has nearly 180 years of experience, so they know a thing or two about great sleep. We’ve designed the Herdysleep mattress to suit the majority of sleepers, rather than overwhelming you with endless options.

With over 6,750 innovative pocket springs, the mattress adapts to your individual sleeping profile and provides the right level of support for your body. And of course, we offer a 100-night sleep trial, so you can try it properly at home, risk-free.

The Herdysleep mattress has a medium-firm feel, offering a balance of comfort and support that works well for most sleepers.

We are so confident that your Herdysleep mattress won’t let you down, we guarantee it for 10 years. In the unlikely event that there is a manufacturing defect with your mattress, we will repair it or replace it, free of charge.

We offer free preferred-day delivery to most areas of the UK*. Your Herdysleep mattress will be delivered by a trusted two-person delivery team and taken into the room of your choice and take away all the packaging. They will also remove your old mattress if you have paid for this service. We work with the UK’s leading home delivery specialists to make sure everything arrives safely and smoothly.

*Please see our Delivery & Returns page for further details.

A signature is required on delivery, so someone will need to be at home to receive your mattress.

Herdysleep mattresses are designed with a single sleep surface, so there’s no need to flip them. We do recommend rotating your mattress to help the fillings settle evenly. Handy stitched-in handles make this nice and easy.

For the first three months, rotate once a month. After that, rotating twice a year is plenty, we find the change of the clocks is a good reminder.

Like most brand-new products, your Herdysleep mattress may have a very slight natural scent when it first arrives. We double-wash our Herdysleep wool to keep this to a minimum. Simply ventilate your bedroom for a few days and any scent will quickly fade. This is completely normal for mattresses made with natural fibres.

Your Herdysleep mattress will work well with any good-quality bed base, as long as it’s in solid condition. If slats are weakened or your frame has seen better days, it can affect how well your mattress is supported.

Top tip: If you’re using a slatted base, make sure the slats are no more than 75mm apart to give your mattress the support it needs.

We design Herdysleep mattresses to be practical as well as luxurious. Despite being packed with a full Herdwick fleece and up to 6,750 individual Herdysleep pocket springs, the mattress is just 27–30cm deep (measured from base to crown and depending on whether you choose a standard or pillowtop). Standard flat sheets should fit perfectly. If you’re using fitted sheets, just double-check the depth to be sure.

Yes – a mattress protector is a great investment. It adds an extra layer of protection to help keep your mattress clean and fresh. We recommend a wool-filled mattress protector, as it allows your bed to breathe and means you’ll still enjoy all the natural benefits of sleeping on wool.

Even with a protector and sheets, a little dust and fluff can build up over time. Every few months, gently brush the surface with a soft brush to remove it. Avoid vacuuming, as this can disturb the natural fillings.

For accidental spills, dab the area immediately with a dry cloth. If a deeper clean is needed, use mild soapy water and allow the mattress to air dry completely before remaking the bed.

Yes – absolutely. Every Herdysleep mattress is rigorously tested, both in-house by our expert mattress maker and independently, to meet UK fire regulations. These are the strictest in Europe, so you can sleep easy knowing your mattress meets the highest standards.

Our mattresses are made by a National Bed Federation (NBF) approved manufacturer, which means they adhere to the NBF’s strict code of practice. This covers everything from supply chain checks to compliance with regulations on flammability, cleanliness of fillings and accurate trade descriptions.

Our mattress maker was also awarded NBF Bed Manufacturer of the Year 2025, so you really are in expert hands.

All components comply with UK fire regulations BS7177:2008 Low Hazard for domestic use – the most demanding standard in the industry.
