What our reviewers found

Pros

10 year warranty is market leading.

Thick and luxurious at a mid range price point.

Well established brand that serves their consumer base well.

Cons

Price point may still alienate some looking for something cheaper.

Turning and rotation of the mattress can be cumbersome given the weight and volume of the product.

We've got a Millbrook Smooth Tech Luxury 5000 Pocket Mattress on the cards today and what a fantastic offering from the popular and prestigious manufacturer. For those not in the know, Millbrook Beds are well established in the arena, selling primarily higher quality products in the mid-tier price point. They represent a great opportunity for those that are looking for a more premium nights sleep and the Smooth Tech 5000 Pocket takes that and dials it all the way up to 100. Let's jump into what this one is all about.

First, the support layer; 5000 premium pocketed springs that are housed in their own individual fabric pockets, all ready to contour to your each and every movement. Available in a soft-medium tension, these springs will best suit side sleepers and will allow you to fully sink your hips and shoulders into the depths of the mattress while you sleep. Back sleepers may be satisfied with this degree of tension also, though should consider something firmer if they are heavier than standard as the sinkage may otherwise be suitable.

Onto the comfort layer which sits at the top of the mattress and you get natural fillings of wool and cotton, available in a deep layer that proves to be both breathable and luxurious. This type of mix works well for many people that get too hot at night and require something more ‘all-season' that will allow them to sleep deeper and longer. It has been an industry trick for decades to not be specific about the exact GSM of the fillings in mattresses, to help create a bubble of uncertainty. This isn't changing with the Smooth Tech Luxury 5000 unfortunately, but, just look at the size of the thing, you can see the sheer volume of fillings from a mile away and it is clear that the quality and structure of the mattress will keep you comfortable for years to come.

You get a 10-year warranty, plus Mattress Online's 100-Night Comfort Trial if you buy their protector with the mattress. The trial lets you exchange the mattress rather than get a refund if the comfort isn't right.

Owners mostly describe it as comfortable, and several mention the support. One wrote "Great mattress very comfy but with plenty of support", and another praised the "Good solid construction, great medium firmness". One owner did find it a "bit firmer than expected". Another blamed the handle placement after they "had a really difficult time trying to turn it".

How it scores

Scored from the build: how this construction usually performs, compared with mattresses of a similar type and price.
Scored from the build: how this construction usually performs, compared with mattresses of a similar type and price.

Suitability

  • Back Sleepers 3.5/5
  • 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 4/5
  • 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 3.5/5
  • 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 4/5
  • Mattresses that feature breathable materials help promote airflow and keep you cool making for a more hygienic night's sleep.
  • Turning on mattress 5/5
  • 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 4/5
  • 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 5/5
  • 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 4.5/5
  • 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 5/5
  • 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 4.5/5
  • This is based on community driven customer reviews tied to product reviews and grouped together at a brand level to produce a score.

Such a comfy mattress, like sleeping on a cloud, just the right firmness for us, soft but not so much you sink. So you get support too.I'm a side sleeper and my partner is more of a front sleeper, it the cushioning works for us both.

Good Points: was comfortable from the first Improvement Points: Mattress need to be turned weekly but only has an end handle on one end so making it quite difficult. The two handle on each side are set so far apart that you cannot put a hand on both to lift, we had a really difficult time trying to turn it

The most comfortable bed you'll ever buy.. The best quality too. It was to replace my old Millbrook bed that I had for 30years! although sleeping on it did show signs of age, to look at it, it was as good as the day I bought it.. The best investment you'll ever make in a bed.
