Testing team takeaways

To test the Flaxby Masters Guild 3450 Pocket Sprung Mattress we have people from our testing team take a closer look at the mattress and form their own opinions. Below is their observations.

I tried the Flaxby Masters Guild 3450 Pocket Sprung Mattress on the shop floor at a Dreams store, lying on my back, front and side to see how each position felt. At 66 kg, I found its medium-firm feel gave me ample support on both my back and stomach, with the springs adapting well to my body. The natural fillings added a soft surface, and it felt noticeably cool to lie on, which I appreciated as I tend to feel hot. On my side, though, there wasn't quite enough give around my shoulders and hips, so it felt a little firmer than I would choose for that position.

What our reviewers found

Pros

  • The Flaxby Masters Guild 3450 Pocket Sprung Mattress delivers exceptional comfort and support, providing an unmatched sleeping experience.
  • Made with natural fillings such as wool, hemp, and cotton, this mattress ensures excellent temperature regulation for comfortable sleep all year round.
  • Its unique, glue-free Cortec™ springs are recyclable, ensuring the mattress is not only durable but also eco-friendly.
  • The mattress offers adaptive pocket springs that provide individualised support, aiding in optimal spinal alignment and relieving pressure points for a restful sleep.
  • Handcrafted in the UK with locally-sourced materials, this mattress exemplifies premium quality and luxurious comfort.

Cons

  • The firm tension of this mattress may not provide the desired comfort for side sleepers or individuals with an hourglass figure due to lack of sufficient sinkage for the hip and shoulder area.
  • It is a single-sided mattress which requires regular rotation from head to foot to prevent formation of indentations, which might be an inconvenience for some users.
  • There is a small learning curve with the mattress' comfort due to the firm feel which may take a few nights to adjust.

Welcome! Today, we're looking into the fascinating world of mattresses, specifically the premium grade luxury Flaxby Masters Guild 3450 Pocket Sprung Mattress. This unique masterpiece of sleep science comes from one of the UK's most renowned bed manufacturers, Harrison Spinks. Combining opulent comfort and ethical sourcing, this mattress is a sign of their commitment to innovation, quality, and eco-consciousness. Strap yourself in for a delightful voyage into the myriad layers of this sublime creation.

How We Test

Our thorough, assembly of evaluations are the cornerstone in our crafting of in-depth, unbiased mattress reviews. Essentially, we concentrate on design, features, customer experiences, suitability, and all unique aspects of the item. Although our review doesn't house an at-home sleep trial, much of our exploration happens in person - including physically testing the mattress in-store, investigating the materials used and even talking to the people who sell the mattresses to gather as much data as possible. We pay extra attention to genuine customer reviews for a rounded perspective.

Design and Features

We start our journey diving into the clever design and structure of the Flaxby Masters Guild 3450 Mattress. The secret lies within its core that is stacked with 100% recyclable, glue-free Cortec™ springs, available in both medium and firm comfort grades, that adapt to your body with precision. Richly filled with a synergistic blend of naturally grown British wool, hemp, and cotton, this mattress doesn't just promise comfort; it commits to controlling your temperature too, regulating it throughout the year across all seasons. It's detailed with two rows of detailed side stitching that heighten its durability and enhance the edge support. The mattress takes solid strides as it sports a single-sided design, promoting low maintenance. However, regular rotation is recommended for optimal longevity.

Mattress Comfort

Comfort is what owners of the Masters Guild 3450 write about most. This attribute is probably one of the most critical factors when choosing a mattress. With its combination of soft, natural fillings, and robust pocket springs, the mattress promises superior comfort and support that can enhance the sleep quality of most individuals, regardless of body weight or favourite sleep position.

Suitability

Nevertheless, comfort often goes hand in hand with suitability. The firm tension of the Masters Guild 3450 caters primarily to back sleepers or even those who sleep on their stomachs, delivering precise support that keeps your spine in an optimal position through the night. On the downside, side sleepers or people with curvier body types may find this mattress a bit on the firm side, since they usually require more sinkage for their shoulder and hip area. Therefore, it's crucial that potential buyers deliberate on their personal needs and preferences before making a decision.

What Customers Thought

Customer reviews are a telling and useful source of information. Owners mostly write about comfort, and a good few say they are sleeping better on it. One called it "firm whilst still being comfy". Another found it "neither too firm or too soft", though that owner needed a few weeks to get used to it. Owners who moved over from memory foam say it sleeps cooler. Not having to flip it is welcome too: "no need to struggle overturning the mattress, just rotate", one owner wrote. Where price comes up, it is usually as expensive but "worth the investment". It doesn't suit everyone. One owner found it "too firm for us" and exchanged it, and one who chose the medium said it was "like sleeping on top of a rock".

The Verdict

The Masters Guild 3450 has a lot to offer - from its eco-friendly, clever design to its luxurious comfort and support. However, it might not be perfect for everyone. While back and stomach sleepers may find the firm tension ideal, side sleepers or those curvier body types might need a softer mattress. Its weight could be a challenge for some, coupled with an ambitious price tag that might deter the budget-conscious. Nevertheless, its merits largely outweigh its demerits, making it a worthy contender in the market of high-end mattresses.

The Flaxby Masters Guild 3450 Pocket Sprung Mattress - it's more than just a mattress. It's a commitment to quality, comfort, and a quest for a sustainable planet.

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.

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

This is far the worse mattress I have slept on . I choosing this mattress as my previous one was faulty declared by the insurance. I was so looking forward to a good night sleep with this mattress and I'm so disappointed . Even my faulty mattress was comfortable it's the 2nd fault mattress I get from Dreams ,and now I have a mattress I can't sleep on , I have got this mattress since the 25th of July yet I didn't had a good night sleep,it's like sleeping on top of a rock. The mattress it's a medium-comfort grade I want to get red off as soon as possible. I contacted Dreams on the chat for an exchange of the mattress I been told I need to wait 30 days . At the moment we are sleeping on the spare bedroom.

We've been extremely happy with the Flaxby Master's Guild 3450 Pocket Sprung Mattress. From the first night, it felt noticeably supportive while still being comfortable and luxurious. The mattress strikes a great balance between firmness and cushioning. The high pocket spring count provides excellent support, particularly for the lower back, while the natural fillings add a soft, breathable feel that prevents the mattress from feeling too hard or rigid. It's supportive without being uncomfortable, and you don't sink in too much. Motion transfer is minimal, which is a big plus for anyone sharing a bed - movements are hardly noticeable. The build quality feels premium throughout, from the stitched edges to the overall weight and structure of the mattress. It genuinely feels like a well-made, long-lasting product. Temperature regulation is another standout. The natural materials help keep the mattress cool and comfortable through the night, even during warmer conditions. Overall, this mattress feels like a real upgrade in terms of comfort, support, and sleep quality. It's ideal if you're looking for a supportive mattress with a touch of luxury, and it definitely lives up to the Master's Guild name. Highly recommended.

The Flaxby Master's Guild 3450 Pocket Sprung Mattress arrived well packaged and at the expected time and date. My husband sleeps well on it. I find it supportive and comfortable, neither too firm or too soft. However, it has taken me a few weeks to get used to. I understand this is to be expected with any new mattress. It's an advantage that it only needs to be rotated, not turned, as mattresses are heavy.

Really comfortable mattress. worth the money - it's made in the UK too so no airmiles! We are using a mattress protector too. We chose this initially for the height (I couldn't get on our old mattress as it was 34cm high and I have MS so was straggling to get on it - literally!). This soon became our favourite when we popped in to Dreams to try them out..

The mattress is super comfortable and the man in the shop was lovely and helpful. Unfortunately the delivery men were unhelpful- i paid for them to bring the bed inside I am 89 years old - they very reluctantly took the old mattress downstairs but said they would be done for fly tipping if they left it outside ( i arranged for council to pick it up),

The staff at Dreams were very helpful and the delivery guys were great, a very good shopping experience.

A great traditionally made, natural mattress. We had such a comfortable bed whilst staying in a holiday apartment, that we made a note of the name and found that Dreams stocked the very mattress. It's so comfy and now We Are On Holiday All The Time!

Very comfortable and cool mattress. Previous mattress was memory foam and didn't last very long even though it was a good quality / expensive mattress. This one is so much better. It's cooler and is more comfortable to lie on.

It is the most comfortable mattress I have ever used, and excellent quality and value. Much better than the previous mattress which wasn't comfortable but around twice the price of this one, so I am really delighted with it.

If you prefer a tradition non Foam Mattress this is the one. Now feel we are on the bed rather than trapped in foam getting hot and not in a hole. Its also a thinner mattress that you don't need steps to get on too!
