13 June 2024 4 min read

In this Millbrook Wool Luxury 4000 Pocket Mattress review, we're going to see whether this luxury mattress has what it takes to help you sleep like a log every single night!

Hybrid mattress has been one of the most popular, if not the most popular type of mattress on the UK market for some time now. If you cut one hybrid mattress in half, you would find layers of memory foam and some type of springs in most of them.

So we decided to test Millbrook Wool Luxury 4000 pocket premium mattress which is a real refreshment because instead of memory foam, it contains wool.

And if you have any questions after reading our Millbrook Wool Luxury 4000 Pocket Mattress review, ask away in the comments!

Who is Millbrook Wool Luxury 4000 pocket mattress for?

Millbrook Wool Luxury 4000 pocket mattress is a medium firm mattress and our tests have shown that it is suitable for all types of sleepers. On a firmness scale of 1 to 10, it is somewhere between 6 and 7, depending on your body weight. 

This gives enough firmness and support for the back and front sleepers, and the side sleepers will be satisfied with the necessary sinkage for that sleep position. Of course, it's a superb for combination sleepers because the springs adjust quickly improving their sleep quality.

It is very breathable, so it is great for hot sleepers. It is also good for people who have allergies, unless they are allergic to wool.

What do we use this product for?

We use Millbrook mattress for an additional support and comfort. Thanks to its structure, it will provide a comfortable night's sleep, and will not compromise spinal alignment. We also use it for sleeping in cool and pleasant environment. 

Features you should know about Millbrook Wool Luxury 4000 pocket mattress

As Millbrook Wool Luxury 4000 pocket mattress is not another generic mattress on the UK market which is essentially no different from many others in the same price range, it is important that you know more about each of the most important features of this product.

a close up image Millbrook Wool Luxury 4000 pocket mattress
Luxury Hampshire fleece wool

This mattress has two blissfully comfortable layers of wool. The top and bottom layers are made of high quality Hampshire fleece wool. When you think of wool, your first associations are usually hats, scarfs and sweaters, so you wonder if this mattress will be too hot for you. However, this will not be the case because wool is one of the best temperature regulating materials in the sleep industry, both natural and synthetic.

Hampshire wool is a premium British wool that has been obtained from Hampshire sheep for almost 200 years. It is thicker, fuller and more resilient than standard wool. Wool is naturally breathable, so you will always be cool and dry, which is pleasant and hygienic. If you are wondering what the role of the bottom wool layer is, it is practically the same as the top layer. And that is to improve air circulation on all parts of the mattress. Wool provides additional support too, not just temperature control. We have to mention wool is naturally fire resistant as well.

4000 individually-nested pocket springs

Between the two woolen layers, there are 4000 individually-nested springs. That number does not vary depending on the size, so whatever size you buy, your mattress will have 4000 individually-nested pocket springs.

There are many benefits of individually-nested pocket springs. First of all, they provide fantastic support and adapt very quickly to your movements during the night, which is why this mattress is a great choice for combination sleepers. Since each spring is wrapped in a cloth pocket, this means that each spring acts independently and provides a different level of support in different places. Motion isolation is another benefit of this type of springs and that is why it is considered to be the best type of spring system.

Traditional hand tufting & reinforced edges

Hand tufting is a manual labour process where the layers are joined to make the mattress completely stable and durable. The manufacturer opted for this traditional method, which is the best, but more expensive and complicated, so some other manufacturers just decide to avoid it.

Also, this mattress has reinforced edges, which further improves durability as well as edge support that is usually problem at mattress border.

Soft viscose-cotton fabric cover

Just like wool, English cotton is world famous for its quality. Soft viscose-cotton fabric cover has several roles on this mattress. It is there to give you a soft sleep surface, although since the cover is not removable, we assume you will use bed sheets for cleanliness. Also, the cotton cover is highly breathable, to complement the breathability of this mattress. Lastly, the luxurious viscose-cotton fabric cover is visually appealing, so mattress will stand out in the room.

Double-sided

We always like when the mattress is double-sided because it prolongs its service life more than when it is one-sided so you can just rotate it. When it is double-sided every couple of months you can flip it and get a completely rejuvenated sleep surface. Millbrook Wool Luxury 4000 pocket mattress has high-quality built-in turning handles, which is very important because this is a heavy mattress, so lower quality handles would probably be unusable after a few moves.

60 night trial & 10 year warranty

It takes about a month for your body to fully get used to the new mattress and for you to know if you should keep it or not. This means that 60 night trial is enough, but to be honest, we think that the manufacturer should offer a longer trial period than that, since this is a premium product.

The 10 year warranty is great for a piece of mind and it is the industry standard for products of this level. In order to benefit from this warranty, please ensure that you register your new mattress within 60 days of your purchase date.

Review of Millbrook Wool Luxury 4000 pocket mattress

an image of of Millbrook Wool Luxury 4000 pocket mattress in a bedroom

Millbrook Wool Luxury 4000 pocket mattress is a hybrid mattress that is 28 cm deep. It has three layers that are hand tufted for maximum stability and durability. The top and bottom layers contain wool, and the middle layer consists of 4000 individually-nested pocket springs.

All this together makes this mattress highly supportive and breathable. Edge support is equally good due to reinforced edges. It is great for couples as there will be no roll-together or roll-off during the night. Soft viscose-cotton fabric cover is comfortable, attractive and breathable too.

It comes with 60 night trial and 10 year warranty. It is significantly more expensive than the average mattress, but the price is completely justified. The only way to maintain it is spot cleaning, so it is best to use bed sheets.

KEY FEATURES:

  • Type: Hybrid
  • Firmness: 7/10
  • Thickness: 28 cm
  • Sizes: Single, Small Double, Double, King, European King, Superking
  • Warranty: 10 years

Check the alternatives to Millbrook Wool Luxury 4000 pocket mattress

We singled out two alternatives to Millbrook Wool Luxury 4000 pocket mattress and we didn't want to list other Millbrook mattress, but rather two from other manufacturers that are both also made in the UK.

Tennyson 4000 Pocket Sprung Orthopedic

a product image of Tennyson 4000 Pocket Sprung orthopedic mattress

The Tennyson 4000 Pocket Sprung orthopaedic mattress and our reviewee have many similar features. Firmness is very similar, and the depth is identical – 28 cm.

Therefore, it is suitable for all sleep positions. It is finished with a hand-tufted pattern for added durability.

Air vents make this mattress super breathable. The soft cotton cover is not removable.

This is an orthopaedic mattress which, along with 4000 pocket springs that give you support, also contains an abundance of wool and cashmere, which are premium temperature-regulating materials.

Edge support is not that good, but motion isolation is great. It comes with a 5-year warranty which is fine but we expected a 10-year warranty considering the price tag.

Check our Tennyson 4000 pocket sprung orthopaedic mattress review.

Signature 3000 Pocket Crystal Pocket Sprung

a product image of Signature 3000 Pocket Crystal Pocket Sprung mattress

If you want a more affordable pocket sprung mattress that has all those plush fillings, like wool and cashmere, in it, then Signature 3000 Pocket Crystal pocket sprung is a great choice.

It is 3 cm thinner, which implies it is 25 cm deep, and it also has a smaller number of pocket springs.

All this does not significantly affect performance, so this is also a highly supportive orthopaedic mattress.

Top-class breathability and temperature regulation provided by natural materials will make night's sleep very pleasant and cool.

Unlike the previous mattress, this mattress is firm, on a firmness scale from 1 to 10, it is around 8, which means that it is too firm for side sleepers. It gives ideal support for front sleepers.

Consider Snuggledown Goose & Feather Down pillow if you are buying Millbrook Wooln Luxury 4000 pocket mattress

a product image of Snuggledown Goose & Feather Down pillow

This pillow is very affordable, especially when we know it is filled with a blend of 85% goose feather and 15% goose down. 

This is an ideal combination because the pillow is then equally comfortable and supportive.

Feather gives firmness and support, and down is added for softness, so you'll be very comfortable sleeping on it.

Snuggledown Goose & Feather Down pillow is medium firm so it is suitable for side and back sleepers.

It is very breathable both because of the filling and because of the cotton cover. The cover is soft and cosy. It is machine washable and tumble dryer friendly.

What makes this product better than some other similar ones?

When we test such a fantastic product as Millbrook Wool Luxury 4000 pocket mattress, it is hard to single out what makes it better than some other similar ones. So we will mention only a few of the best things, while this mattress essentially has no significant flaws. 

Breathability and temperature regulation are the most important features for hot sleepers, and this mattress excels in these categories. Support and motion isolation are great thanks to individually-nested pocket springs. 

This is a very durable mattress, and there is also a 10-year piece of mind warranty. Soft cotton cover is skin-friendly and you can flip it over time to time to prolong its service life even more.

How did we test the product?

An image of a a couple laying down on Millbrook Wool Luxury 4000 pocket mattress

When you order Millbrook Wool Luxury 4000 pocket mattress you have the option to choose any day during the next two months to have the mattress delivered to you, a convenience we have never encountered before when ordering mattress online. If you choose a working day, there is no delivery costs, and if you choose Saturday or Sunday you have to pay 17.5 pounds.

Testing of this mattress took almost a month. Since this is a high-priced product that you will use for the next 10 years, maybe more, it was out of the question to miss anything.

When it arrived, we first checked every part of the mattress, where of course we did not notice any damage or bad craftsmanship. We then registered the mattress to qualify for a 10-year warranty. The roller test showed a high level of durability, and after that, we started overnight testing.

For more than two weeks, members of our test team slept on it, in different sleep positions and changing sleep positions during the night. We also tested it in a room with central heating to check breathability and temperature regulation. Couples tested King size to make sure of motion isolation. All of this was necessary so that we could present this review to you. And we'd say that Millbrook beds live up to the price tag!
