How to choose a Sealy Sanctuary mattress?

There are a total of four mattresses that are part of the Sealy Sanctuary collection (Haven, Senses, Oasis, and Spa).

  • Their price ranges from £799 – £1,199 (for a single size).
  • The first thing you’ll notice is that their comfort level varies from medium, firm to extra firm. There is no “soft” option, but as an alternative you can check out the Staples and Co Artisan mattress collection
  • Also, the mattress depth ranges from 30cm to 39cm.
  • Lastly, another factor you should consider is how many pocket springs you want the mattress to have. The Sanctuary Haven and Senses have 1,500, while the Oasis has 2,300 and the Spa has 2,900. Generally the more pocket springs, the better body support they offer. 

Now let’s look at the similarities between the four Sealy Sanctuary mattresses. All of them use Sealy’s exclusive Posturepedic Technology, a layer of Innergetic Latex® (for pressure relief), a layer of Quantum Edge® pocket springs (with edge support) and are treated with Purotex®, to fight off dust mites and other allergens. All of them come with a 10 year guarantee.

Shopping Tip: Make sure you also check out the Sealy PostureLux Mattress collection. Inside there is PostureTech Core Support Plus™ springs with six turns for increased height and support and Latex Comfort Layer.

Sealy Sanctuary vs. Tempur Mattress

Before you decide if the Sealy Sanctuary mattress is right for you, it’s good to compare it to other competing brands. For example, the TEMPUR CoolTouch Sensation Mattress also has a firm feel. It’s an all memory foam mattress (without any springs inside), but has a special Dynamic Support Technology layer, which creates a feeling of bounce. The TEMPUR CoolTouch Sensation Elite Mattress is 25cm deep and is priced at £1,299 for a single size, making it the more expensive option. 

There is also the Tempur One mattress, which comes in soft, medium or firm. It distributes body weight evenly and creates a sense of weightlessness when you lay down on the mattress. It’s 20cm deep and is priced at £999 for a single size, which is more expensive than the Sealy Sanctuary Heaven and Senses mattress.

Sealy Sanctuary Mattress Reviews

When opting to buy a top-of-the-range product that comes with a high price tag, it’s important you first do your homework and find out what people who have already purchased it think of the mattress. The great news about the Sealy Sanctuary collection is that the mattresses boast a range of extremely positive reviews from customers on Trust Pilot. The highest rated mattress is the Sealy Sanctuary Spa with 4.9/5 stars from 40 reviews, but is also the most expensive. 

Pros:

Although several reviewers mention the fact that they considered their mattress to be expensive, they all agree that it was worth the money they paid. This is sufficient proof that the mattresses justify their tag and are worthy of your consideration.

Universally, the vast majority of reviewers have commented that their Sealy mattress is extremely comfortable and has greatly enhanced their sleeping experience. Given the high-tech features described above, this is hardly a great surprise.

Cons:

There aren’t many negative reviews of the Sealy Sanctuary collection to choose from, but a couple of customers have mentioned that both the Oasis and Senses mattresses were firmer than they expected when delivered. Even after lying on them in-store, they were surprised that they felt too firm after sleeping on the mattress at home for a while. Also, keep in mind that the Sealy Sanctuary Spa mattress is 39cm high, which is a bit higher than some customers expected and needed time to get used to it.

Overall, if the Sealy Sanctuary range is within your budget, they should be well worth your consideration. Being handmade in the UK and comprising high quality, patented materials, each of the four mattresses we’ve introduced in this guide will significantly improve your night’s sleep.
