Tests & Verdict

Here we collect tests, guides and product reviews so that you can create a picture of what others think about the product. This analysis and review is based on my experience and 12+ years of industry insight.

It's getting harder to find Sealy products at low and budget price points as the manufacturer aim to retake much of the premium segment and cut their losses downstream. The result is you likely won't find many at this price point that feature the Core Support system and if indeed you are looking for a firmer nights sleep, this could be the one for you.

Might not be around long depending on the direction that Sealy go in next, so consider buying now to avoid disappointment.

Why our sleep experts loved it

Sealy have redesigned their entire range recently, leaving chaos in its wake and leaving customers and retailers alike confused about what the new lineup looks like. The advantage range is carved up under different names across different retailers but the general comfort and support is fairly generic. The Advantage Classic utilises the Sealy Core Support spring system which offers a firmer tension than standard proving ideal for those looking for more orthopaedic support from their sleep.

So who exactly will benefit from this type of mattress? Back and stomach sleepers mainly. See, the firmer tension is a tough ask for average weighted people who sleep on their side as your hip and shoulder end up rolling rather than sinking so unless you are heavier than average, the firm should be for back and stomach sleepers.

Where does this mattress fit in the range? Sealy's new ambitions (and recent separation from the Silentnight Group) see the brand trying to establish itself once again as a premium-tier experience, dropping the majority of it's low-budget segment and pushing higher pricing via its unique support systems and strong legacy.  This particular model fits within the shrinking budget lineup, providing a great price for a well established brand, but does it live up to the hype? I think so. The support layer of Core Support is unique to Sealy and has long term reviews around its use, providing a firmer experience that gives sufficient body contouring at a reasonable cost. The comfort layer too has some impressive qualities, in this instance featuring a quilted sleep surface and reflex foam underneath, the combination provides adequate sinkage and protection from the springs while giving a fair amount of breathability for what amounts to a soft-meets-firm combination of comfort and support.

From a firmness perspective, we find the Core Support range and its orthopaedic properties sit at an 7 on the firmness scale, with some customers remarking that they expected it to be slightly firmer. We've tried the Core Support system before in other products in the lineup and the number tends to float between 7 and 8 depending on the comfort layer associated with the mattress. A 7 is a nice happy middle-ground, not so firm that you cannot appreciate the softness of the comfort layer, but not too soft that you don't get the orthopaedic properties and rigid back and neck support.

Customers love it too, with over 150+ reviews and a (to date) 82% 5 star rating, this is certainly one of the best options for those on a budget. Those same customers particularly enjoyed the value for money and the rigid and ortho support offered living up to expectations. Those who didn't enjoy it felt that it was too soft, or too firm. This sort of complaint comes up a lot and it is almost always down to subjectivity as one persons interpretation of firm is not the same as another. Body weight can also play a huge role in this and so to offset it, utilise the little tool below to see how firm, or soft the mattress might feel depending on weight.

  • 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

  • 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.

Because of an accident at home, I ended up needing a mattress urgently and got this one as it was next day delivery in lockdown and came highly recommended. So far so good, I am pleased with my mattress, it is value for money, however, I am a lil sad to know it isn't as environmentally friendly as I hoped. Please give it a thought before buying your next mattress if it isn't urgency.

I really love this mattress. I bought it to replace an old mattress that was causing stiffness and interrupted sleep every night. Since then I have slept soundly with no stiffness or soreness in the mornings! the mattress is medium and just the right feel. It is made to a high quality and I would recommend this mattress for its comfort, quality and price.

I struggle to sleep on 'memory foam' and even on just plain pocket sprung mattresses which are invariably on the soft side for me.The mulberry is a basic traditional sprung mattress with a soft top but firmer and more supportive inside, so it does feels as though you are sleeping on it rather than in it which suits me just fine.

Bought this to replace the existing mattress my daughter had and wasnt disappointed. Comfortable mattress that she said has been the cause of a fantastic nights sleep.Although we could have gotten it a few pounds cheaper, the company promised next day delivery and didnt fail on that. Thoroughly recommend!

The product is really good quality. The only thing is it would benefit from handles on the mattress to assist with turning as when you are on your own it can be difficult and handles would be great. My previous sealy mattress had handles and it made the job so much easier.

This mattress is very comfortable. It supports me well and is firm but not too much. From the first night I have slept so much better on this mattress. The best thing is that I no longer bounce around when my husband rolls over! I recommend this mattress

Trusted manufacturer and a quality mattress. Ordered 'medium' which at first felt very firm but have adapted to it and now find it extremely comfortable -- firm/soft in all the right places.

Looks well made, is as expected. Bought as a guest room mattress and therefore has not been slept on as yet, hence four stars. A quick test suggests it will be comfortable.
