Product Description

The Sealy Casoli 1200 Mattress is Now Discontinued.  Click here to view the current Sealy Range.

The Sealy Casoli 1200 is a superb Mattress in the Sealy Posturepaedic Pocket Collection. This excellent Mattress is a has won the Which? Magazine Best Buy Award, three years in a row! This 1200 Pocket Spring mattress is the best-selling mattress and divan in the Sealy range.

The Sealy Casoli 1200 mattress is the best-selling mattress and divan in the Sealy Pocket Collection and is available in a range of sizes – including single, double, king size and super king size.

It features 1200 pocket springs, each acting independently to support the body's contours exactly where required. This type of spring is set in its own cotton pocket, and will not affect its neighbouring springs as weight is applied. This simple yet effective detail means that the springs can concentrate on a specific area of the body, ensuring accurate and precise support. The mattress is also zoned which means that the areas that carry the majority of the bodyweight (lumbar region, shoulders) will receive more accurate support and will in turn help to reduce aches and pains. Unirail encases the spring unit to provide added durability and prevent the mattress from sagging over time.

The Sealy Casoli features natural Latex. Latex is designed to further enhance the level of support the body will experience, as well as offering an extremely luxurious sleeping surface. Latex also has anti-bacterial properties, offering a clean and fresh feel to the mattress.

Finished with a luxurious quilted fabric, the mattress features a combination of smart fibres. Tencel is an eco-fibre that works to create a cool, dry and irritation-free sleeping environment. Endorsed by Allergy UK, Purotex prevents the build-up of dust mites and allergens. It is also designed to keep your mattress clean, fresh and odour free- so that over time your mattress feels just as good as the day you placed it in your home. Adaptive technology absorbs moisture to regulate your temperature and keep you cool.

This top-selling Sealy mattress is a non-turn mattress for easy care but does have handles for easy movement when required. The Casoli 1200 Pocket mattress has a guarantee of 5 years as standard.

Who Is This Mattress Best Suited For?

The Casoli is a hugely popular mattress and is suitable for all sleeper types. We would recommend this mattress to people looking for a combination of great support and luxurious comfort. As this is a non-turn mattress, it is also perfect for those who want low maintenance or are physically unable to lift the mattress over. Remember, we do all the lifting and unpacking when we deliver to you!

    Disappointing
    This matress was comfy for the first 2+ years but once it began to sink that was not the case. Now, after exactly 3 years it's a mess.
    Come on Sealy, get your act together. If it's got a 5 year guarentee, it should last 5 years!

    Warranty replacement already sinking
    I'm on my second one of these (warranty replaced due to sinking). The We've had the replacement about a year and even though regularly turning it, it's sank where we lay again. I don't know if I'd be better with a standard pocket spring with no foam/geltex topping. It was very comfy when new though. Shame it didn't last.

Glossary

  • Foam Encapsulation

    Foam Encapsulation is a recent addition to the bedding market. An idea designed to offer greater edge-to-edge support as well offering greater Bedstead/Slatted base compatibility.

    The idea is simple; Create a spring unit and then sit it in a 'matchbox' of Foam. As you can see in the diagram below, the spring unit is surrounded on all sides by a layer of Memory Foam. This foam gives a solid, stable feel to the mattress and allows the spring unit to be completely separated from the mattresses fillings and cushion. 

    Once the spring unit is set in the foam and the foam glued together, it can be surrounded by fillings and fibre to create the traditional look for a mattress or can be given a Pillow Top for even more comfort.

  • Latex

    Latex is the ultimate in luxurious natural materials (but can be synthetic in other markets). Latex is actually found in more than 10% of flowering plants around the world. About 20,000 species from more than 40 families. The Latex used in the bedding industry is taken from sustainable sources. Latex is perfect for mattresses because it is soft, hypoallergenic, natural and moulds to the shape of the body. 

    Latex used in bedding also tends to be treated in such a way that it can be used by people who have Latex allergies! The technique used is to super heat the Latex unit, freeze it, super heat it and freeze it again. Once this process is complete, the harmful chemicals released can be chemically washed off, leaving it suitable for everyone. Latex is the material Memory Foam has tried to copy. Memory foam  requires heat to mould to the shape of your body and can therefore become too warm for some. Latex does not require heat and is soft at any temperature. As a natural material which requires time and various processes to be extracted, Latex can be more expensive that its rival materials, but the comfort levels achieved are well worth it.

  • Pocket Sprung

    Pocket Sprung units are an adaption of the traditional open coil/continuous spring unit. By placing each spring in its own individual 'pocket' (a fabric sock-like pouch), the spring is not joined to any other part of the mattress. The pocket that supports the spring is then joined to its neighbouring pockets and this effect creates a unique feel.

    By creating a spring unit in this way, it allows the springs to move independently, rather than sharing the pressure with surrounding springs. This effect allows for much more accurate contour following and a more comfortable feel overall.

    If you were to push your hand into a traditionally sprung mattress, the area around your hand would dip/sink too. With Pocket Springs, this sunken area is much more remote and therefore more accurately follows the contours of the pressure source. There are differences in the techniques used to create Pocket Springs, but more or less they remain the same.

  • Warranty

    Every mattress we sell comes with at least a 12 month manufacturers guarantee, though most come with much longer guarantees. To find out what mattress warranty is included with your purchase, look out for the rosette on the top right corner of the mattress page. All new goods are sold with a minimum 12-month manufacturers guarantee. Full details are available on request. In addition to the manufacturers guarantee MyNextMattress offers a limited extended mattress warranty. This warranty varies in length item by item. You must keep all your purchase records as they will be needed in the event of a claim. The warranty is applied as follows:

    • The mattress warranty is against faults in manufacture, not wear and tear or damage.
    • The mattress must always be used with a mattress protector, turned and cleaned as per the manufacturers instructions and must be unsoiled at the time that the claim is lodged.
    • The claim must be registered with MyNextMattress by email or in writing. All details of the claim must be lodged with MyNextMattress by email or in writing.

    If the claim is accepted the following process will apply:

    • We will arrange to collect the goods and return them to us for inspection.
    • The carrier reserves the right to refuse to collect items that are not packaged suitably or which is unhygienic.
    • We may require pre payment for the costs of the collection in some circumstances.
    • If we validate the claim we will contact you to arrange the replacement goods to be dispatched to you and delivered to you on a date that is convenient for you.
    • The replacement item can be any item from our then current range.
    • The difference in price from the warranty covered item is payable by you, along with the cost of collecting the original item.

    There will be an allowance granted against the replacement item according to the following scale.

    • If the claim is validated within the first two years - 40% of the original price will be credited.
    • If the claim is validated in year three of the purchase -25% of the original price will be credited.
    • If the claim is validated in year four of the purchase - 15% of the original price will be credited.
    • If the claim is validated in year five or (if warranty is for longer than five years then any subsequent year up to the warranty period) -10% of the original price will be credited.

    The warranty is only applicable to the original purchaser and is only valid if approved by MyNextMattress. It should be considered as extra peace of mind in case of manufacturing defects that arise after the manufacturers mattress guarantee has expired. It should not be regarded as a guarantee that any item will last for any particular period of time, or as a guarantee against deterioration in performance. It is in addition to your statutory rights. There is no entitlement to a cash payment in lieu of the replacement. The replacement item must be at the same or higher price than the original.
