frequently asked questions

Where are Herdysleep mattresses made?

All Herdysleep mattresses start life in the Lake District but are handmade in Yorkshire by luxury bed manufacturers Harrison Spinks. They even design and make our pocket springs and weave the unique chemical-free sleeping fabric all onsite in their workshop.

Tell me more about what’s inside my Herdysleep mattress!

At Herdysleep we care about the detail, and we’re passionate about making things by hand right here in Britain, using as many British-born materials and British-nurtured skills as we can. As Herdysleep began in the Lake District and wool makes for an excellent mattress filling, responsibly sourcing fleece from friendly local Herdwick sheep was the obvious choice. Herdwick fleece goes into every Herdysleep mattress, so each night, as you doze off, you can count the sheep, and the farmers, that you’ve helped support. With all our natural materials in place, including the finest cashmere and cotton, we turned to expert bed makes Harrison Spinks, to handcraft a superior mattress that’s traditionally stitched, tufted, and bursting with over 7,000* bouncy Herdysleep pocket springs.

Why do you only sell one mattress?

Our mattress maker have been crafting mattresses for nearly 180 years, so they know a thing or two about making mattresses. We’ve designed the Herdysleep mattress so that it suits the majority of the population. With over 7,000 innovative pocket springs, the mattress will mould to your individual sleeping profile and provide you with the correct level of support for your body.

Of course, don’t forget we offer a 100 night sleep trial so if you are not 100% satisfied with your Herdysleep mattress, you can return it free of charge.

What’s the firmness of the mattress?

The Herdysleep mattress is a medium-firm feeling mattress.

What is our 100 night sleep trial?

Let’s be honest, you can’t really know for sure if a mattress is absolutely right for you after just a few sleeps. It’s a big investment and we want you to be 100% satisfied that you’ve made the right choice. So, sleep on it for up to 100 nights, and if at any point during that time you do not feel it is right for you, we’ll send a courier to collect your Herdysleep mattress free of charge and refund you in full. All we ask is that you give your mattress a chance for at least 30 nights, because if you’ve been sleeping on your previous mattress for the last 10 years it always takes a little time to get used to something new. If you’re still not sure, just contact us on to arrange a pickup that’s at a time convenient to yourself.

How does our 10 year guarantee work?

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 problem with your mattress construction, we’ll repair it or replace it, free of charge.

Will a courier deliver if I am not at home?

The courier will require a signature so someone will need to be at home to sign for the delivery.

Do I need to turn or rotate my Herdysleep mattress?

A Herdysleep mattress has been perfectly designed, layered with bouncy Herdysleep pocket springs and resilient Herdwick wool, so it doesn’t need to be flipped. However, we do suggest that you rotate your mattress to help the fillings settle evenly. For your added convenience, mattress handles are sewn to the border to assist you when rotating.

For the first three months, try to rotate once a month, and after that, twice a year should do the trick. We tend to remember when the clocks go forward and back.

Will my Herdysleep mattress smell?

Just like with any new product, don’t panic if you detect a slight odour when opening the product. It’s completely normal with natural fibre mattresses and will fade away in no time at all.

What type of bed base can I use with my Herdysleep mattress?

Just like you, your mattress wants to lie down somewhere comfortable and deserves a good quality bed base. If your bed slats are weakened or your frame has seen better days, it can compromise the support of your Herdysleep mattress. Therefore, treat it well, and in return it will reward you with a good night’s sleep so that you can take on the world.

Tip: if you are using a slatted base, make sure the slats are no more than 75mm apart to support your mattress properly.

How deep is the mattress – will standard sheets fit?

A Herdysleep mattress is all about being convenient for you and so although it’s packed with a full Herdwick fleece and 7,400 individual Herdysleep pocket springs it is just 26cm deep so standard sheets should fit just fine.

Would you recommend a mattress protector?

A mattress protector is a worthy investment - it provides your mattress with an extra layer of protection to ensure it stays spick and span. Always opt for a mattress protector with natural fillings so your bed can breathe, such as the Herdysleep wool mattress protector.

How do I clean my Herdysleep mattress?

Even with a mattress protector and sheet in place, dust and fluff will always find a way into your bed, so every few months, grab yourself a brush and sweep it all away. Steer clear of using a vacuum as it dislodges the natural fillings. If there are any accidental spillages on your mattress, just dab them with a dry cloth. If you need something a little more thorough, use mild soapy water and let it air dry fully before you remake your bed.

Can I use an electric blanket with a Herdysleep mattress?

Of course you can, however, a Herdysleep mattress has a wonderful natural sleeping surface which will help to regulate your body temperature and using an electric blanket means that you are unlikely to feel this benefit when the electric blanket covers this surface.

Do Herdysleep mattresses pass all of the safety standards?

All of our mattresses have been rigorously tested both in-house by our expert mattress maker and by the UK mattress regulatory body to pass UK fire regulations, which are the strictest in Europe. Of course they are also a National Bed Federation (NBF) approved member, having been approved by the NBF’s strict code of practice ensuring processes and procedures are in place for supply chain scrutiny and compliance with regulatory requirements, including flammability, cleanliness of fillings and trade descriptions. Our mattress makers were even presented the Bed Manufacturer of the Year Award 2015/2016 by the NBF, so we really are working with the very best.

All components comply with UK fire regulations BS7177 Low hazard for domestic use - the most stringent in the industry.

Will you take my old mattress away?

If you have an old mattress that your new Herdysleep mattress is replacing, you can select our free mattress removal service at checkout for no extra charge. Our delivery team will provide a bag with your mattress delivery and take it away to ensure it is recycled and disposed of in an environmentally friendly manner – see our delivery page for more details.
