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.

Sealy have been on a bit of a frenzy to redo much of their range in 2022 and one of the victims of this was the previous Sealy Millionaire mattress. Now rebranded as the Alford Advantage, it comes with a few new tricks that might satisfy your needs.

One of Sealy's most popular mattresses which offers great orthopaedic support through the firm support layer in the product.

Well reviewed and highly recommended.

Unlikely to find equivalent orthopaedic support at this price point.

Impressive 5 year guarantee which rivals far more expensive products.

Standard sprung tensions don't perform as well as pocket springs and typically have poorer edge support. They can still provide good body contouring and often offer better value than pocket springs.

Why our sleep experts loved it

Your mattress needs to be comfortable, supportive and have a quality you can trust. That’s why so many manufacturers offer great beds that meet all your needs. If you’re looking for the best mattress to suit your lifestyle and budget, the Sealy Alford Advantage Mattress could be the right fit. These top-rated mattresses are made with quality components and feature unique spring systems and comfort layers that you won't find from other brands. These materials provide ultimate support and comfort at an affordable price.

The Sealy Alford Advantage is a medium depth, firm mattress designed to support the back and also to promote good posture. With a new PostureTech Core Support Spring system, this mattress reduces the pressure points that can cause pain in the shoulders and hips, and is double-sided so it can be flipped to extend its life. 

This mattress has been manufactured at Sealy's UK factory, which holds Good Manufacturing Practice and ISO9001 accreditation

.The mattress also benefits from PostureTech Core Support - a strong, resilient core of spring units designed to provide support to the natural contours of your body - and an Orthopaedic Support Rating. It is 28cm deep and has a firm feel which will suit buyers that need a bit more support and are primary back sleepers. Side sleepers should perhaps consider a slightly less firm product as the sinkage may not be suitable.

The mattress is made up of a Damask cover that is handcrafted in the UK using a traditional open coil spring system. It is finished with turning handles for easy rotation and a 5 year guarantee.

Reviews for the Sealy Alford are strong with over 700 reviews to date, although some of these were from when the product was known as the Millionaire which featured a slightly different cover and design. Component wise however, the Alford is the same and the customers love it with many commenting on the great back support and low price point. There were a few concerns from others that the product was a bit too firm, however we known firmness is subjective and will naturally vary customer to customer.

Suitability

*Assuming average weight, suitability will vary dependant on body type, use the quiz above for a more tailored guide.
  • 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.

Ease of Use

  • Turning handles
    ★★★★★
    ★★★★★
  • 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
    ★★★★★
    ★★★★★
  • 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
    ★★★★★
    ★★★★★
  • 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
    ★★★★★
    ★★★★★
  • This is based on community driven customer reviews tied to product reviews and grouped together at a brand level to produce a score.

Although with this mattress it took roughly around a fortnight to get used to the higher firmness level to what my former mattress was as initially I did think it was took firm I discovered that I know prefer this firmness level more. As a regular gym attender (around 5/6 times a week) I used to always suffer from aches and pains, this mattress has helped reduce those. I now very rarely wake up having had a bad night sleep due to discomfort/aches and pains. The support level provided on ones posture is so much more beneficial. The cost of the mattress was a little more than I would normally spend in a mattress but overall I am getting a better nights sleep which is a big plus :D I would highly recommend.

For under 300 including delivery, this mattress is real value for money. Great support for the back and the top is quite soft so good quality. Wherever you roll on the bed it doesn't seem to sag. Slept on so many bad mattresses in my time so very pleased with this purchase. This is one of those internet gems where you pay a good price and get quality. Not really knowing about Sealy beforehand and then speaking to family members, they have all voiced that Sealy are a very good brand so hoping it will last a number of years.

Very comfortable, especially now we've added a 2" silent night memory foam topper. It beats the 1,400 Millbrook mattress which it replaced, and had failed after less than five years.Don't let the bargain price put you off...This is a superb value for money mattress.Sealy are the chosen supplier to Holiday Inn in the USA, where we stay often, and always get good sleep. The extra charge for the 2 man delivery is worth every penny. Installed and took packing away. Well done!

I have had the mattress for about 5 weeks and have found it very comfortable from the start and have had a good night's sleep from the first night. It gives good support and helps alleviate any back ache that results from my work. The mattress is heavy and I would expect most people would need 2 to carry it, though my son did get it upstairs by himself.

Mattress appears to be OK.But when one has muscular problems around a right hip (complete joint replacement 12 year old),one tries anything to improve ones sleep. It's all in the mind, believing a different mattress would change things. Still get out of bed with pain, but subsides as the day wears on. So curing pain does not come from a new mattress.

The mattress is super supportive, and it is firm so if most of the time like me sleep on your side I would opt for medium firm mattress, unless you are heavy set person. This mattress is turnable not just rotates. It has turn handles to help with this. It is very thick which make my bed super high to get into (not complaining about that at all).

The springs provide what really is firm support but do have some give in them. Very good value for money for an orthopaedic mattress. Not sure what it's longevity is like as only owned it for 2 months. Would recommend to a friend with a bad back or preference for firm support over comfort.

Have experienced sciatica for several years, after switching to this mattress approximately a month ago I have not had a single recurrence. This is still early days to say it totally has resolved my issue but I am extremely pleased with this mattress and would not hesitate in recommending it.

Bought as an identical replacement for the one originally supplied with the Sealy bed we purchased about 8-10 years ago. The springs had lost their firmness especially with my 20st+ weight on them over time. It had proved to be of excellent quality hence the one for one replacement !!!
