In our experience, the materials and construction that go into this product can make it suitable for the following people.

What our reviewers found

Pros

  • Comfort is what owners praise. One wrote that they "actually wake up feeling refreshed", and another liked the "very comfortable pillow top".
  • The build is pocket springs with Comfonomic micro springs, and one owner called it "definitely not a flimsy mattress".
  • One owner found it "great for both side and back sleeping".
  • It can feel firmer than its soft to medium rating at first. One owner "Thought at first it was going to be a bit hard" and, a few weeks in, called it "lovely".
  • The comfort layer is a blend of wool, cotton, silk and cashgora. Mattress Online lists the finish as chemical-free.

Cons

  • Given the softer profile of this mattress, individuals with a higher Body Mass Index (BMI) or those who prefer a firmer sleeping surface may find it lacking in adequate support.
  • Despite the presence of natural materials, this mattress may run hot for some individuals due to its plush pillow-top construction.
  • While the comfort layer is composed of a blend of natural fibres, those with allergies or sensitivities could potentially react to the materials such as wool or cashgora.

An Introduction to the Millbrook Smooth Tech 5000 Pillow Top Mattress

Finding a perfect night's sleep often means wading through an ocean of mattress choices. One such option that might catch your eye is the Millbrook Smooth Tech 5000 Pillow Top Mattress. Its promise of a cosy, supportive, and technologically advanced design seems to beckon every sleep enthusiast.

How we assessed it

On paper this is a soft to medium mattress on a seven-zone pocket spring core, 32cm deep, with the layers tufted in place and the border braced by a flat frame, a rod frame and butterfly springs. That border should let you sleep right out to the edge, which counts for a lot on anything smaller than a king. It's single-sided, so you rotate it with the handles and never flip it. Check your fitted sheets are deep enough before it arrives. A few owners found it harder than the soft to medium label suggests, which is what I'd expect from tufted natural fillings while they're still tightly packed. That should ease as the fillings settle, and one owner said it had after a few weeks.

Design and Features

The Millbrook Smooth Tech 5000 is a mattress made with an ergonomic blend of pocket springs and Comfonomic micro springs. This pairing provides an impressive support structure, effectively managing pressure points and providing a sleep experience that could leave you waking up feeling refreshed.

Not all 5000 springs are full pocket springs. A significant percentage are micro springs, which, though offering a unique level of comfort and contouring, may not provide the same support as their full-size counterparts.

The Millbrook has a luxurious pillow-top layer that adds an extra layer of comfy cushioning. However, pillow tops can sometimes be a contentious feature. Some find that these extra layers can compress over time, slightly reducing their initial levels of comfort and support. So while the pillow top may initially seem an enticing plus, potential buyers should consider the long-term implications of this feature.

The mattress's comfort layer is a delicate blend of natural materials such as wool, cotton, silk, and cashgora. These natural fibres work in harmony to give a snug and sumptuous bounce, assuring your body feels caressed and cradled as you sleep. This blend also manages to strike a perfect balance of providing cooling relief during summer and comforting warmth during winter, making the Millbrook a versatile option for year-round comfort.

Mattress Comfort

Comfort is at the core of the Millbrook Smooth Tech 5000, offering a soft to medium firmness that is perfect for side sleepers or those with lower body mass indexes (BMIs). This level of firmness adequately supports the hips and shoulders, allowing a satisfactory level of sinkage from the support layer and providing relief from potential pressure points. The perfect firmness is, to some extent, subjective, and depending on the sleeper's comfort preferences, a softer mattress may not always be the ideal choice.

Suitability

The soft-medium tension, coupled with its robust ergonomic design, makes the Millbrook Smooth Tech 5000 Pillow Top Mattress a well-suited sleep companion for side sleepers or those with a lower than average BMI. This particular group often benefits from the optimal level of support and comfort provided by the mattress, thereby promoting an enhanced sleep experience.

It may also appeal to individuals with hourglass figures who require additional sinkage from the mattress' support layer for balanced body weight distribution and enhanced comfort. As with all mattresses, this product may not be suitable for all body types and sleep positions, so consider your personal comfort preferences when making your selection.

What Customers Thought

Most of the reviews are happy ones, and comfort is the word that keeps coming up. One owner wrote that they "actually wake up feeling refreshed". Another called it "Very comfortable just what I wanted". The build gets credit as well, with one owner saying it "is definitely not a flimsy mattress and has a very comfortable pillow top" and that it "has been great for both side and back sleeping". It is a deep mattress, which one owner noticed: "much higher than we had before, which is a bit strange getting in and out".

The complaints are about firmness. One owner found it "Very hard for a soft to firm Mattress". Another sent it back as "Too dense really bad for my arthritis". A third "Thought at first it was going to be a bit hard" and, a few weeks in, called it "lovely". Firmness, like comfort, can be subjective, and what feels soft to one person may feel firm to another. Also, since mattress firmness tends to adjust over time, keep in mind that a mattress will naturally become slightly softer with use.

The verdict: Millbrook Smooth Tech 5000 Pillow Top Mattress

The Millbrook Smooth Tech 5000 Pillow Top Mattress, built with ergonomic design and natural materials, offers an inviting promise of a wonderful and rejuvenating night's sleep. The use of pocket springs and Comfonomic micro springs combined with a luxurious pillow-top layer and natural fibre blend in its comfort layer presents a compelling choice for any sleep enthusiast.

However, be mindful of the pillow top layer feature, because despite the enticing allure of extra cushioning, it might compress over time, subsequently altering its initial level of comfort. Also, some owners found it harder than its soft to medium rating suggests, so keep in mind that your own comfort preferences matter a lot in choosing the right mattress.

Despite these considerations, the overall product quality and the mostly positive owner reviews, paired with its credible UK based manufacturing and generous 10-year warranty, make the Millbrook Smooth Tech 5000 a laudable contender.

Suitability

  • Back Sleepers
    ★★★★★
    ★★★★★
  • The amount of support offered from a mattress will vary depending on the firmness of the tension and the type of support layer used. Based on a person of average build.
  • Side Sleepers
    ★★★★★
    ★★★★★
  • If you sleep on your side you typically need a supportive tension that is not too firm, nor too soft. This is because your hips and shoulders need adequate sinkage.
  • Stomach Sleepers
    ★★★★★
    ★★★★★
  • Stomach sleepers need a reasonable amount of tension in the base support layer to adequately offer body contouring and help prevent aches and pains. Results will vary based on your build.

Performance

  • Breathability
    ★★★★★
    ★★★★★
  • Mattresses that feature breathable materials help promote airflow and keep you cool making for a more hygienic night's sleep.
  • Turning on mattress
    ★★★★★
    ★★★★★
  • Certain materials like memory foam can make it difficult to move about on the mattress while you toss and turn. Same too for pillow tops which can create a cloud like sensation which can make manoeuvrability challenging.
  • Stability
    ★★★★★
    ★★★★★
  • Depending on the type of support layer in place can have an impact on stability, edge to edge support and roll together prevention. Pocket springs of a firmer tension will have better stability than open coil soft tension, for example.

Ease of Use

  • Turning handles
    ★★★★★
    ★★★★★
  • Mattresses typically need to be rotated frequently and having turning handles can be massively beneficial, particularly in larger sizes which can become fairly heavy.

Odour

  • Initial Odour
    ★★★★★
    ★★★★★
  • Materials in mattresses, particularly memory foam and rolled bed-in-a-box mattresses can have an initial odour, this is typically short term and reduces considerably within 24 hours.
  • Long Standing Odour
    ★★★★★
    ★★★★★
  • Certain materials inside different mattresses can produce a small odour. Typically this is short term rather than long standing but there are minor exceptions.

Brand Rating

  • Overall Brand Rating
    ★★★★★
    ★★★★★
  • This is based on community driven customer reviews tied to product reviews and grouped together at a brand level to produce a score.

We got what we paid for, an expensive purchase that we hope will last for more than 20 years like our old mattress. The new mattress is much higher than we had before, which is a bit strange getting in and out, but we trust the pillow top will remain soft and comfortable.

The mattress is made of great materials and is very neatly and comprehensively put together. It is definitely not a flimsy mattress and has a very comfortable pillow top. It has been great for both side and back sleeping.
