Sealy Harlow Ortho Plus Mattress

FirmnessFirm

In shortNow sold as the Sealy Harlow Ortho Plus, with soft white fibres where the memory foam was. Back sleepers who like firm support get a softer touch from those fibres. I'd pass if you sleep on your side, and reviewers mention softer edges. Read the review

What our reviewers found

Pros

Firmness: People who prefer a firm mattress will like this product as it provides good support for their back.

Comfort: Owners mostly find it comfortable, and a few say they're sleeping better, one calling it "So comfortable best sleep in years".

Fibre comfort layer: The listing now shows soft white fibres as the comfort filling over PostureTech Core Support Springs, in place of the memory foam layer.

Good value: Value comes up regularly in the reviews, with one owner calling it "Lovely and comfortable, brilliant value".

Quality:From a manufacturer as good as Sealy, the quality and durability of the product is very high.

Cons

Limited sleep positions: It suits back sleepers better than side sleepers. One owner put it bluntly: "Not suitable if you sleep on your side."

Feeling springs: One owner wrote that you "can feel the springs through it as well" and asked for thicker padding.

A good night's sleep can send you through loads of mattress options, each with their own specs and potential benefits. Today, we set our sights on the Sealy Harlow Ortho Plus Mattress. This particular model is touted for its orthopaedic support and strong structure, optimised to provide restful nights for those who need a bit more strength in their sleep surfaces. As someone with a decade-long love affair with everything 'mattress,' I find it fascinating to look into the details of a product like this.

Design and Features

The Sealy Harlow Ortho Plus Mattress comes with unique PostureTech Core Support Springs, an intelligent design element from Sealy providing full-body support and pressure relief.1 The mattress is firm and thoughtfully conceived for those requiring orthopaedic assistance. The damask cover gives it a soft touch without heat retention, adding to its allure.

One interesting feature is its single-sided construction, which removes the need to flip the mattress. Instead, rotating it every few months does the trick in terms of maintenance. At 26 cm deep, it hits a comfortable median in terms of mattress thickness, ensuring it plays well with most bedding, toppers, and bed frames.

Perhaps, one of the more notable aspects of the Sealy Harlow Ortho Plus Mattress is that it's handcrafted in the UK, helping support the local industry and bring down the overall environmental impact. The mattress is also fire-resistant, in line with BS7177: 2008, the UK standard for items intended for home use.

Mattress Comfort

The Sealy Harlow Ortho Plus Mattress, being orthopaedic in nature, provides strong support and a firm sleep surface. These types of mattresses are designed for those needing enhanced spinal alignment, joint support, and improved posture. These are important considerations for sleepers suffering from back issues, recurring aches, or pains. The mattress also features a tufted sleep surface, which results in a sturdier, firmer feel, delivering a night of truly restorative sleep.

Sealy has filled this model with soft synthetic fibres, striking a balance between comfort and resilience. It's clear this mattress was designed with a foot firmly planted in the pursuit of the ideal firm mattress.

Suitability

Based on its specifications, the Harlow Ortho Plus Mattress has an unmistakeably firm tension, pegging it as best suited for back sleepers. Those with specific requirements for orthopaedic features or persons advised by a medical professional to opt for this degree of firmness should find this mattress beneficial. That being said, it may not be ideal for side sleepers, though some stomach sleepers might benefit. As always, suitability is subjective, and personal comfort and needs should be a decisive factor.

What Customers Thought

Owners who wanted a firm, supportive mattress mostly got one. One owner with back trouble wrote that "this mattress is nice and firm. Perfect and comfy", and another said it gave them "all the comfort and support for a good night's sleep".

The most common complaint is that it's softer than the Firm label suggests. "Quite a soft mattress, certainly not as firm as I had expected," wrote one owner, and another found it "quite bouncy for what is meant to be a firm mattress." Some say it doesn't spring back, with one writing that "it doesn't recover after getting of mattress very well". The edges get a mention too: one owner found the sides "so soft that when I reached over to put something on the night table I fell off."

The Verdict

The Sealy Harlow Ortho Plus Mattress certainly takes a stronghold among firm, orthopaedic support options. However, the reviews aren't one-sided: most owners are happy with the support, while others found it softer than expected or slow to recover. It underlines the significance of personal preference when it comes to firmness and comfort.

While customer feedback and property analysis can guide us, there always lies a blind spot in terms of individual preference and comfort requirements. The main takeaway here is that the Sealy Harlow Ortho Plus Mattress is evidently a value-for-money proposition for those seeking a firm, orthopaedic mattress, provided they're comfortable with the notion of it being firmer in the middle and softer around the edges.

Another point to highlight is the mattress's sustainability and recyclability. Eco-consciousness plays a big role for a lot of people, and Sealy's push towards sustainability gives this mattress an added edge.

Ultimately, the decision to invest in this mattress should be made with careful consideration of the person's specific sleep pattern, comfort preferences, and medical recommendations. It would also be advisable to weigh the complaints about softness and slow recovery before jumping into a purchase decision.

Considering the current circumstances, I personally see a rising trend in the number of people seeking firm, orthopaedic mattresses and it's highly satisfactory to see manufacturers like Sealy cater to such needs. However, the Sealy Harlow Ortho Plus Mattress may be a tad too specialist for the regular customer, who may prefer a compromise between firmness and softness.

Ultimately, the mattress market remains persistent in its diversity. In my decade-long experience with mattresses, I have seen a lot of offerings designed for specific preferences and needs. It's absolutely key that the choices we make match our individual requirements for the ultimate pursuit of the perfect good night's sleep.

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.

Great firm mattress. You can tell the structure is high quality, judging by the material that the mattress is covered in and the useful handles on the sides to ease manouvering the product and turning it.I was a little concerned about the memory foam aspect, as previously a full memory foam mattress didn't suit my partner, it made him sweat quite a lot. However, we have had no problems with this.Overall, we have found this to be very comfortable and great value for money.

My former mattress was a cheap one by dreams, it was like sleeping on stones. This one on the other is another story. It's quite firm but very supportive. This is also my first memory foam mattress. I have sciatica flare ups which happen in random places and this mattress really helps me get comfy without feeling any pressure in the bad areas. I got this mattress while on offer so it was super expensive.

Not being able to compare, without trying loads of mattresses, you have to go with 'description and instinct'.It doesn't disappoint: it's firm, but not 'bone hard', very supportive and comfortable. I was a little concerned that the 'memory foam' top might be too warm, but I needn't have worried; it's fine. So, if like me, you prefer a firm mattress at a bargain price, then this is for you.

Firmer than I expected it to be. It is a very firm mattress. You don't sink into it. I like this and my back has been better. Feels like a quality product that will last. I was worried that I wouldn't like the memory foam but I can't really feel it, it just feels soft. Great mattress if you like a firm one ?

It's completely not supportive to the back. I'm just 100 pounds. But the bed is simple sank when I slept on it. I can't imagine that they said the firmness is at level 4. I have a back pain after I slept for a week.
