Wool Mattress Topper Buying Guide
What is a Mattress Topper?
A mattress topper is a removable layer that sits on top of your mattress to enhance your comfort and support. It’s designed to help you fine-tune the feel of your bed and, in turn, improve your overall sleep experience. Whether that means adding softness to a firm mattress or providing extra stability to one that feels too plush, the right mattress topper can be totally transformative in delivering a better night’s sleep.
What Does a Mattress Topper Do?
Think of a topper as a comfort upgrade. It’s there to make your sleep surface better – whether you’re a hot sleeper looking for temperature regulation or someone affected by back pain who needs that firm support.
Many sleepers use a topper to breathe new life into a tired old mattress – that extra layer can make all the difference to your sleep experience. Others use one to enjoy an extra layer of indulgence when they lay their head to rest.
How Does it Differ from a Mattress Protector?
Why Use a Wool Mattress Topper?
We firmly believe wool is the secret ingredient to a better night’s sleep. They don’t call it ‘nature’s wonder material’ for no reason. Here are just some of the reasons why a wool mattress topper from the Woolroom can benefit your sleep health:
-
Temperature Regulating
Wool’s naturally crimped fibres create air pockets that help regulate your body temperature. This keeps you cool and dry during those hot summer nights, and comfortably cosy during the cold winter months. It’s the perfect material for anyone who sleeps hot or experiences temperature fluctuations during the night. This effect is even stronger when you combine a wool topper with a wool protector.
-
Hypoallergenic
Dust mites and allergens thrive in warm, humid conditions. Wool’s ability to absorb moisture (such as when you sweat) and release it into the air creates a dry environment - one that’s inhospitable to bacteria and dust mites.
-
Flame Retardant
Wool is one of the most flame resistant bedding materials – particularly when compared to polyester and nylon. In order to make these synthetic materials fire resistant, they have to be chemically treated. Wool can offer this same benefit without the need for any chemicals. So you can rest easy knowing your topper provides peace of mind.
-
Breathable
It’s normal to sweat during the night – it’s your body’s natural response to regulating temperature. Unlike synthetic materials that trap heat and capture moisture, wool wicks it away and releases it, keeping your sleep environment fresh and balanced.
-
100% Natural British Wool
All our toppers are filled with fully traceable British wool, sourced from sheep raised on a natural diet of grass, water and sunshine. Thanks to our Wool ID® programme, you can trace the wool in your topper right back to the farm it came from.
-
Made to Last
In an era of fast homewares, we’re proud to create products made to last. Wool is extremely resilient – its fibres bounce back to shape rather than flatten over time. With regular airing and the use of a mattress protector, your topper can provide up to 10 years of support. And when you need to replace it, it’s 100% biodegradable – leaving behind no harmful residues or microplastics.

Which Woolroom Mattress Topper is Best for You?
When you buy a Woolroom topper, you’ll get a product that’s filled with 100% British wool. So, you’ll enjoy all the same natural benefits – hypoallergenic qualities, temperature-regulation and breathability.
But they’re not all the same. The main difference lies in the depth, feel and the level of support you prefer. We’ve put together this quick guide to help you decide which one best suits your sleeping style.
| Topper | Best For |
|---|---|
| Deluxe Wool Mattress Topper | Everyday comfort and a subtle layer of softness. Ideal for side or combination sleepers who want to refresh a mattress without changing its overall feel. |
| Organic Wool Mattress Topper | Sleepers who prefer fully certified organic materials and a slightly deeper, more luxurious feel. Perfect for those seeking the cleanest, most natural sleep environment possible. |
| The Woolly Sprung Mattress Topper | Sleepers who prefer deeper cushioning and extra lift. Great for those with back or joint discomfort, or anyone looking to transform a firm or ageing mattress. |
Can You Wash a Mattress Topper?
No, you can’t wash our mattress toppers – but you don’t need to. Being the naturally breathable wonder material it is, wool effectively cleans itself. Any moisture it absorbs is released back into the air.
Instead, you can simply freshen it by hanging on the line outdoors to refresh the fibres and release any moisture. Do this once a month to keep it in the best condition.
Do not machine wash our toppers – as this can damage the natural structure of the wool, reducing the support it provides.
Where Does a Mattress Topper Go on Your Bed?
This is a common question and an important one – especially if you’re buying your first topper. Your bedding layers should be arranged as follows:
1. Mattress
2. Mattress Topper
3. Mattress Protector
4. Fitted Sheet
Placing your protector above your topper keeps both layers hygienic and helps to prevent any spills or stains seeping through. All while maintaining the breathability and loft of your topper.
Will a Mattress Topper Help with Back Pain?
The right topper can help to alleviate the discomfort caused by back pain.
The gentle, pressure-relieving support provided by our wool toppers won’t fix a sagging mattress. But they can improve spinal alignment and reduce the tension caused by overly firm or uneven surfaces.
We recommend the Woolly Sprung Mattress Topper for those who suffer with back pain. The additional lift provided by its micro coils can help maintain a neutral spine position throughout the night.
Why Does a Topper Work Better with a Protector?
Think of them as a sustainable dynamic duo – the topper enhances your comfort, while protector safeguards your sleep sanctuary. When combined they create a cleaner, more comfortable set-up that lasts longer. Using a wool mattress protector will:
- Keep your topper and mattress free from spills
- Reduce the need for any spot cleaning
- Extend the lifespan of both layers
- Enhance the brilliant natural benefits wool brings to your sleep environment – from temperature regulation to breathability to reducing the impact of allergens

FAQs
How Thick Should a Mattress Topper Be?
It’s all about personal preference. Our wool toppers range from 4cm to 10cm thick. Thinner options add a soft layer of comfort, while thicker designs can significantly alter the feel of your mattress.
How Long Should a Mattress Topper Last?
With the correct level of care, a wool topper can last between 5 and 10 years, which is far longer than synthetic, feather and down alternatives. Regular airing and using a protector will help to maintain its condition.
How Do You Stop a Mattress Topper from Slipping?
We know this is a common problem for sleepers. It's why our toppers feature elasticated straps that secure neatly around your mattress corners. Pairing it with a protector or fitted sheet also will also help keep it firmly in place.
Can You Put a Topper on a Hybrid Mattress?
Absolutely. Wool toppers complement all mattress types - including hybrid and memory foam models. We recommend going for a wool mattress, topper, protector and duvet combination for the very best night’s natural sleep. However, by adding the natural breathability and comfort of a wool topper, you can significantly enhance the quality of your rest.
Are Mattress Protectors Breathable?
Yes, ours are! Wool allows air to circulate freely, unlike plastic or fully waterproof synthetic membrane alternatives.
Can a Wool Mattress Protector Stop Bed Bugs?
A wool mattress protector can help reduce the risk of bed bugs reaching your mattress, but it won’t stop an infestation on its own. Wool fibres create a naturally clean, breathable environment that’s less attractive to pests like bed bugs and dust mites.
However, bed bugs can still hide in other areas of your bed, such as the headboard, frame, or nearby furniture. That’s one of the reasons we recommend choosing a complete wool sleep setup - to create the cleanest, healthiest sleep environment possible.
How Long Should My Mattress Protector Last?
With proper care, one of our protectors can last between 8 and 10 years – all thanks to wool’s natural strength and resilience. It really is nature’s wonder material!
