Why our sleep experts loved it
The Sealy Broadwood Ortho Firm is Bensons for Beds' house version of a traditional orthopaedic mattress. At its heart is Sealy's PostureTech Core Support spring unit, and the cover is a tufted damask cloth in the time-honoured British tradition. If you are looking for a proper, old-school firm bed, it is exactly that – and very much not a fluffy, cloud-like mattress.
I find it does what it says on the tin, albeit I only trialled this for half an hour in the local Bensons showroom. Strong in both overall firmness and, crucially, edge support. I love the ability to use every single centimetre of the surface and the secure feel of the perimeter, which is particularly stiff and stable on this mattress. On my back I find it holds my body and my spine in a gently supported position, but I do think the price is high enough to make pocket sprung Hypnos and Relyon options start to come into play, which makes that value-for-money conversation a little more complex if you are not catching it on a good Bensons sale.
Construction & materials The Broadwood Ortho Firm is 27cm deep, which puts it comfortably in the mid-height range that still works with standard fitted sheets and is not too tall for most people's taste. Inside is Sealy's PostureTech Core Support spring unit, a traditional interconnected system that has been tempered twice to enhance its resilience. It is designed to offer progressive resistance, with the springs firming up under increasing weight and providing more support the deeper you sink.
Sealy has included a reinforced zone through the central third of the mattress, which it calls the PowerPack. It is not immediately obvious to the naked eye, but it is effectively a firmer area built over the lumbar zone. This is intended to provide a bit more support under the hips and lower back, where we tend to carry more weight and sink further into the mattress. It is this zoning, combined with the overall tension of the surface, that stops the Broadwood feeling like a wooden plank and that helps to maintain your spine in a more neutral position when you sleep on your back.
Over the top of the spring unit you get layers of synthetic fillings, including Sealy's Smartex fibres, which are there to assist with heat and moisture management, and ReNew eco-fibres made from 76% recycled PET plastic. Again, the layers are relatively shallow and are there more to boost breathability and provide a little loft than to offer a sense of plush comfort. That is entirely in keeping with an orthopaedic approach.
Finishing off is a luxury Belgian damask cover that feels more robust than silky-smooth, and the entire surface is hand-tufted, with the tufts pulling the layers together and creating that distinctive, slightly dimpled traditional look. The cover has been treated with ProShield, a skin-safe anti-allergy treatment certified by Allergy UK, which should offer a little extra peace of mind if you suffer with dust mites.
Sitting around the perimeter is Sealy's EdgeGuard, a reinforced edge system that runs in tandem with the main spring unit. On this model in particular it feels very solid. It keeps the structure square and flat, reduces the sensation of rolling off and, most importantly, lets you sleep all the way up to the edge without the mattress collapsing away beneath you.
Firmness & feel I would say the Sealy Broadwood Ortho Firm is a true firm, maybe edging towards extra-firm if you are a lighter weight. There is an initial thin layer of padding from the fibres, but you are quickly on to the spring unit and the overall sensation is of a supportive, slightly bouncy surface that is very dense, rather than a deeply cushioned, sink-in feel.
The zoning does a good job on my back, with my pelvis anchored by the firmer PowerPack area while my upper back and shoulders can sink a few millimetres lower. This encourages a straighter spine, and the overall sensation is very much held in place. It is a bit like having a mattress that is on guard duty for your posture, and if that is what you like, the Broadwood Ortho Firm will probably appeal to you.
Side sleeping is another matter. The comfort layers are relatively shallow and the mattress is tufted quite firmly, so there is very little give around the shoulder and hip. If you are a lighter or slimmer side sleeper, you may well feel some pressure building up in those areas, especially after a few hours. I would not call it all-night, every-night side sleeper friendly, unless you are planning to team it with a fairly plush pillow and perhaps a thin topper to add some extra softness.
On your front the firm, level surface works well to prevent your hips from sagging too much, which in turn helps to reduce stress and strain in the lower back. If you roll between back and front as you sleep, the Broadwood does a good job of keeping you perched on top of the bed rather than allowing you to sink in and get stuck.
Where it really excels, I think, is at the perimeter. EdgeGuard is very effective on this mattress, so you can sit on the side to get dressed without dramatic compression, and it feels almost as solid as the middle when you are sleeping near the edge. If you are a couple on a double and find you tend to push each other out towards the sides over time, that is genuinely useful.
Performance & support There is no doubt that support is the Broadwood Ortho Firm's headline feature. The PostureTech Core Support springs provide a consistent level of support and bounce along the length of the mattress, and the PowerPack adds additional rigidity in the central third to counteract the weight of the midsection. What this means in practical terms is that your hips do not slump into the mattress as they might on a softer or more foam-intensive design, which can be a real plus if you have lower back niggles and struggle to feel like you are being adequately lifted.
If you are an average to heavier-weight back sleeper, that combination of support and central stiffness works well to keep the spine reasonably neutral with minimal muscle effort. Lighter-weight sleepers will probably find it veers towards hard, especially in the first couple of weeks before the top fibres relax a little.
It is worth saying that this is a traditional linked spring unit rather than a pocket sprung core, and there are some consequences to that choice. The upside is a slightly livelier, more responsive feel and strong central support. The downside is that there is a greater potential for movement to travel across the surface, so if your partner is restless or likes to get up and down at different times, you are going to feel more of their movements on this mattress than you would on a well-specified pocket sprung or hybrid design. The tufting does its best to quell some of the bounce, but I would not put this at the top of the list if you are particularly motion-sensitive.
Edge performance, as noted above, is another big plus. EdgeGuard really holds that perimeter firm, so you can make full use of the mattress's width without feeling like you are perched on a cushion the whole time. For couples on a double, or anyone who likes to stretch out a bit, that additional usable space is genuinely a luxury and one that not all mattresses in this price range can match.
In terms of long-term resilience, the twice-tempered springs, the tufted construction and the overall firm specification should, in theory, mean the mattress wears quite slowly, as there is not a lot of ultra-soft foam in it that will compress and break down over time. Sealy backs the Broadwood with a 5-year guarantee and Bensons has a 40-night comfort guarantee, so there is some reassurance and a bit of leeway if you are not sure after a while that the firmness is right for you.
Temperature regulation Firm, fibre-topped sprung mattresses like this one tend to be a good starting point if you are worried about overheating, and the Broadwood Ortho Firm leans into that. The open spring unit offers plenty of airflow through the core of the mattress, and both the Smartex and ReNew fillings are there to help wick away moisture and dissipate heat.
The Belgian damask cover is on the firmer, more breathable end of the spectrum rather than thick and backed with foam, so you do not get the slightly clingy, cocooned sensation you can experience with some deeply quilted or memory foam designs. In practice it feels neutral to slightly cool; for average and mild warm sleepers I would happily recommend it. Very hot sleepers may still want to team it with a lightweight duvet and a breathable protector, but it is a better bet than most fully memory-foam mattresses by some margin.
Practical features This is an easy-care, non-turn mattress, so you do not have to flip it over. Instead you simply rotate it head-to-foot from time to time as per the care instructions to even out wear and usage. That is a helpful tip given its firmness and depth, especially if you are doing all the manoeuvring single-handed.
The 27cm depth is sensible and sheet-friendly; it will accommodate most standard deep fitted sheets and will not look too tall or bulky on most divan bases or bed frames. As a traditional, non-rolled mattress it also arrives flat, which means there is no need to wait for it to expand or off-gas and no chance of accidentally unrolling part of the mattress in your haste to get it set up. Bensons will deliver it to a room of your choice, with optional recycling of your old mattress for a fee.
One other point on the health and hygiene side is that the ProShield treatment on the fabric is a useful extra if you are allergy-prone, and the overall firm edge created by EdgeGuard makes it easier to get in and out of bed if you have any mobility concerns.
Finally, we come to pricing. Bensons does have promotions, and they do run from time to time on Sealy ranges including percentage discounts. They also have 0% APR finance available on qualifying orders, which can help with the cost spread out over a year or so. Even with those factors in the mix, the Broadwood Ortho Firm is at a price point where, if you shop around, you start to see entry-level Hypnos or Relyon pocket sprung mattresses coming into the frame, where the entry cost brings with it a more natural-feeling filling palette and a slightly more luxurious specification.
Who it suits Back sleepers who like a genuinely firm feel to their mattress are going to get the best out of the Broadwood Ortho Firm. The PowerPack zoning gives real reinforcement directly under the lumbar area, and the overall level of tension and support is strong enough to hold your spine well aligned without you having to think about your posture every time you get into bed.
Front sleepers and combination back/front sleepers are also well catered for, as the firm surface helps to prevent your hips from sinking too far, which in turn reduces the strain on your lower back. If you occasionally roll onto your side for short periods of time, it is manageable, but this is not a mattress I would choose primarily for side sleeping unless you know you like a firmer-than-average surface.
Heavier sleepers who find medium or soft mattresses too yielding may appreciate the firmer, more resilient feel and the fact that the springs have been designed to increase in resistance the more weight you place on them. There is a sense of structural integrity to this mattress that some cheaper orthopaedic models lack.
Couples who want to use every inch of the mattress surface will love the edge support. If you tend to end up on the very edge of the bed regularly, the Broadwood Ortho Firm feels supportive and secure, which is a real plus in a double or even a king.
Allergy-conscious shoppers might also put this on their shortlist because of the ProShield fabric treatment and the overall synthetic-fibre construction, which tends to be easier to keep fresh with a decent protector and regular airing.
Who it does not suit Predominantly side sleepers , especially those with narrower frames or sensitive shoulders, are likely to find the Broadwood Ortho Firm simply too firm for all-night comfort. The tufts and relatively shallow comfort layers do not offer much cushioning to allow shoulders and hips to sink into the mattress, and for many people that will be a problem.
Anyone craving a plush, hotel-bed feel should look elsewhere. This is the opposite of a pillow-top or deep memory foam mattress; there is almost no sink-in and barely any hug. If you are looking for that cocooning sensation, this is not the mattress for you.
Light sleepers sharing with a restless partner might also be better served with a pocket sprung or hybrid build. Because the springs in the Broadwood Ortho Firm are all linked, rather than individual, they share movement across the mattress more than a well-specced pocket sprung alternative. You are both going to feel more of each other's tossing and turning on this mattress than you would if one of you is particularly active.
Buyers who want to prioritise premium materials at this price point might find the Sealy Broadwood Ortho Firm a little disappointing in comparison with its rivals. For a similar outlay you can get into entry-level Hypnos or Relyon pocket sprung designs, and those come with more natural fillings and often better motion isolation as well. Unless you particularly want Sealy's very particular firm, orthopaedic character and strong edge, I would be cross-shopping quite hard on that basis.
Those who simply do not like very firm beds should avoid it. There is nothing you can do with the right duvet or bedding tweaks to make this a soft or medium feel mattress; its identity is resolutely, unapologetically orthopaedic.
Final verdict The Sealy Broadwood Ortho Firm is a well-built, well-specced orthopaedic mattress that delivers on its central promise: decent support, a genuinely firm feel and solid edge stability. The PostureTech Core Support springs, the central PowerPack reinforcement zone and the robust EdgeGuard perimeter all work in the same direction, giving you a bed that is disciplined, cool and reassuringly solid from the get-go.
It is a no-nonsense bed for back and front sleepers who like a firmer, traditional mattress and want to maximise the amount of usable surface they have on offer. I like the zoned support under the lower back and I like the fact that you can use the full width without ever feeling on the brink of rolling off.
Where I am less convinced is on price versus competition. This feels to me a touch expensive for a Sealy built around an open-coil-style spring unit and a relatively simple fibre comfort system, in a market where pocket sprung Hypnos and Relyon start to bring more luxurious and natural fillings in, often with slightly better motion isolation as well. If you can get it on one of Bensons' regular Sealy promotions, the equation is much healthier; at full ticket I would personally be inclined to shop cross rather than deeply on value.
If your priorities are orthopaedic support, strong edges, a cooler, more traditional sleeping surface and you know you like that held-on-top-of-the-bed feel, the Sealy Broadwood Ortho Firm is worth a look. If you are a side sleeper, motion-sensitive or just looking for plush comfort and luxurious materials, you will probably be better off spending the same money, or perhaps a bit more, on a well-specced pocket sprung alternative instead.
