ConstructionPocket sprung

In shortIf you're a lighter side sleeper, I'd consider this Soft Medium pillow top: pocket springs give it support, while wool and cotton sit in the filling. If you sleep hot or prefer a firmer feel, I'd look elsewhere. Read the review

What our reviewers found

Pros

  • The Harrison Spinks Harewood 4250 Pocket Pillow Top Mattress offers excellent support with its individually cloth-encased pocket springs which expertly adapt to the movements of your body, ensuring personalised comfort.
  • Constructed with natural wool and cotton fibres, this mattress offers temperature regulation properties and wicks away moisture, facilitating a fresh and snug sleeping environment all year round.
  • The mattress employs a traditional and elegant tufting design, mitigating the risk of fillings shifting, shape loss, or sagging, while promoting added stability, thereby ensuring the durability of the construction.
  • With turning handles stitched into the mattress border provided for ease of use, this mattress is not only comfortable to sleep on, but is also convenient to manage and maintain.
  • This UK-handcrafted mattress holds the promise of a five-year guarantee and constitutes a fire-resistant build, adhering to BS7177: 2008 standards, confirming its safety and reliability in domestic settings.

Cons

  • The soft/medium label did not match one owner’s experience: they found it “a lot firmer than I was hoping for and expecting from the soft/medium description”, and “way too hard” on a solid ottoman base. The base underneath changes how it feels.
  • Single-sided, so it cannot be flipped. The listing asks for weekly rotations for the first 12 weeks, then a rotation each season.
  • The pillow top gives the initial plushness, and those layers compress over time.
  • Not the pick for hot sleepers or anyone after a firmer feel.

There is something deeply personal about the mattress you choose to spend your nights on. It becomes your comfortable haven after a taxing day, catering to your body's need for rejuvenating rest. One such mattress offering luxurious comfort and exquisite craftsmanship is the Harrison Spinks Harewood 4250 Pocket Pillow Top Mattress. Made by the prestigious British manufacturer Harrison Spinks, this lavish mattress has been fashioned for an unrivalled sleeping experience. Promising enchanting nights of undisturbed slumber, the Harewood 4250 is more than just a mattress. It's a commitment to restful nights, conducive to sound health and a refreshed mind. Here’s a look at its features, comfort and suitability.

How we assessed it

The pillow top sits on three layers of pocket springs: 2500 high density springs at the top, 1000 Posturfil springs below them and Cortec™ springs at the base. In a mattress 28cm deep, that much springing should follow your shape closely and move with you when you turn, so I'd expect it to suit side sleepers best. The comfort layers are British wool with a blend of cotton, hemp and flax. Natural fillings sleep cooler than foam, but I still wouldn't pick a soft pillow top for a hot sleeper.

One owner wrote “Took only a couple of nights to get myself used to it”. Another found it firmer than the soft/medium description led them to expect, and I'd put some of that down to the tufting, which holds the fillings tight over the springs.

Design and features

The Harrison Spinks Harewood 4250 is no ordinary mattress. Expertly handcrafted in the UK, this mattress features three layers of substantial pocket springs - high density pocket springs, Posturfil pocket springs and, the award-winning, Cortec™ pocket springs. This array of springs is designed to offer unequalled support, pressure relief and adaptability. The Pillow Top layer beckons with the promise of added comfort, heightening the feeling of sleeping on a cloud.

The luxury fibres woven into the design too deserve a special mention. Alongside the springs, there's a layer of British wool known for its breathability and temperature-control abilities. This is complemented by a blend of cotton, hemp and flax fibres which contribute to maintaining an ideal body temperature while sleeping.

The mattress also deserves plaudits for its practical design elements. The addition of sturdy turning handles allows for simple and effortless mattress maintenance. The mattress comes with a luxuriously tufted surface for stability and a reinforced mattress edge that extends the sleeping surface almost to the brim.

Mattress comfort

This bespoke mattress ensures your sleep turns into a luxurious experience. Its medium-soft tension strikes an impeccable balance between firm support and cosy softness, wonderfully accommodating side sleepers and folks with a lower-than-average BMI. The Pillow Top contributes significantly to the initial feel of plush comfort, although these layers do tend to compress over time.

Suitability

The Harrison Spinks Harewood 4250 matches the requirements of side sleepers and those with a lower BMI profile incredibly well. Those with an hourglass physique will find the additional sinkage in the support layer considerably comfortable. Owing to its luxurious appeal and singular comfort, it is a brilliant investment for someone looking for a mattress that prioritises support, comfort and luxury.

What customers thought

Owners mostly rate it well, and comfort and quality are what they mention most. One owner wrote that “the mattress is very comfortable with the correct amount of support”, and another found it “Very comfortable good quality”. The build gets credit too, one calling it “Superb manufacture.” The one reservation is firmness. An owner who bought it on the soft/medium description found it “a lot firmer than I was hoping for”, and “way too hard” on a solid ottoman base, though on a fully sprung base it “works reasonably well”. Prompt delivery comes up as well.

The verdict

Looking at the Harrison Spinks Harewood 4250 Pocket Pillow Top Mattress, what emerges is a beautifully crafted, luxurious mattress teetering on the higher price range. It justifies its cost through its impressive spring structure, well-thought-through comfort layers and engrossing details such as the turning handles. In my view, the seemingly high investment required for this mattress could be its only deterrence. However, those who appreciate the fine art of well-crafted mattress technology will find themselves thoroughly satisfied with this exclusive mattress by Harrison Spinks.

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 3.5/5
  • 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 3.5/5
  • 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.

To be perfectly honest, I'm not convinced but I think the problem is me, not the product. The mattress is clearly very good quality, but it's a lot firmer than I was hoping for and expecting from the soft/medium description. On the spare bed, which is a fully sprung base, it works reasonably well, which is why I haven't yet engaged the 60 day return option, but on the bed I ordered it for originally, which is a solid Ottoman base, it is way too hard. I'm sure that with use it will soften up, but it's still way too hard for me personally to sleep on comfortably and I doubt it will ever be that soft. Indeed, in desperation I ended up going to a shop and buying a much cheaper (and far inferior quality), softer mattress because I simply couldn't do 30 days sleeping on that mattress. I am going to contact Mattress Online today and enquire about swapping it for something softer.
