Sealy Sanctuary Spa Mattress Review

The Sealy Sanctuary Spa Mattress is suitable for all types of people who are looking for a balanced mattress, which is not positioned at the extremes, but has the benefits of something that is both firm yet soft, that is why its medium firmness is ideal. Having the best of both worlds, enjoying softness and support at the same time, is something that only mattresses with this firmness can achieve.

The Sealy Sanctuary Spa Mattress offers you that perfect balance, since you will not suffer excessive sag from a very soft mattress, and you will not feel that you sleep on a stone, as is often the case with mattresses that are too hard. With a medium firmness you will be comfortable, on a smooth surface, but that continues to distribute and support the weight of your body and keep your back aligned during the night. The benefits of each side, but without its disadvantages. It is the perfect combination.

With a latex comfort layer, it offers you great pressure point relief, as well as being the one of the best materials if you find you sweat a lot, as latex is famous for its excellent ventilation and heat management. Additionally, latex is very soft to the touch and is easy to clean and care for. It is the type of material that adapts perfectly to the shape of your body regardless of the way you prefer to sleep.

Its support layer made of the well renowned and well-tested pocket springs, specifically 2900 of them, any more than 1000 already indicates excellent quality. This type of support layer offers end-to-end support for your mattress, making it stable and solid across its entire surface. There will be no part of your mattress that is not firmly held by a spring, this will help you to move comfortably within it providing even tension.

With a 10 year guarantee you get one of the best protections available for any mattress. Typically you only get one year of guarantee for many mattresses so the additional years help showcase the confidence and trust the supplier and retailer have in delivering this product to you.

The top layer gives a clean and sanitized environment with Purotex, which offers antibacterial and hypoallergenic properties that will take care of your health properly. 

Finally, it includes a cushion top, which according to user reviews, makes the Sealy Sanctuary Spa Mattress a comfortable, strong product that will give you from now on a total transformation to your nights, worth every penny.

Reasons to Buy

Reviews are beginning to flood in and there are other people with shared positive experiences. Customers report the comfort as the primary reason for what makes the mattress great, however others too seem to love the support and well-rounded tension which appears to be suitable for both partners while they sleep.

Price point is very reasonable considering the fantastic guarantee on offer.

Reasons to Avoid

At time of writing there is a small lead time on the product that may prove problematic if you need it in a hurry.


What Makes The Sealy Sanctuary Spa Mattress Great?

10-Year Guarantee

A 10-year guarantee is fairly unheard if within the mattress industry. Bear in mind that the average mattress has a lifespan of around 7 years before being replaced and you can soon realize why many suppliers do not offer this length of guarantee. When they do, however, like in this instance, you can be assured of a mattress of good quality because otherwise the retailer and supplier would lose money. As such, buy with confidence, if anything does go wrong, you'll be looked after

Headboard not included

The bed frame comes separate from the headboard for styling and aesthetic purposes. allowing you to pick the right bed frame and headboard for the style of your room.

Mattress height: 39cm

Innergetic Latex insert gives excellent pressure relief

Latex is a luxurious material of natural origins and is one of the better materials for mattress construction due to it's softness, breathability and resilience. You will find latex often used as a top comfort layer and occasionally used as a core/base layer due to it's additional supportive properties.

Firmness rating: Medium

A medium tension mattress is largely suitable for most people of average BMI. Not too soft, nor too firm this mattress has enough softness in the tension to allow you to sink, while providing enough support to contour to your body.

Customer Reviews For The Sealy Sanctuary Spa Mattress

Based on 25 reviews

Love the mattress its massive. A €˜Princess and the Pea mattress! It took a little bit longer than I expected for the €˜new smell to go. I hadnt realised that new mattresses emit gases once taken out of the sealed cover.


A Comfortable bed, although it has taken some time to get use to the height of the bed. Really happy with our choice particularly that it is a really good British make. Thank you.


Bed is super. Very high but comfortable. Not made for short people though, so be aware if your short you will need a very low base. We are tall and get frosty noses. Ah ah.


Was hesitant spending a-lot of money, weve had it a few weeks now and its so comfortable. Glad we got it.


Very comfortable, very cool to sleep on, just what we wanted. Best night's sleep for decades, straight away.


Probably the most comfortable mattress Ive slept on. Great sleep, like floating on air. Wake refreshed.
