Silverdale Mattresses Details

The Sealy Silverdale super king-size mattress will make any master bedroom into a luxurious sleep sanctuary and is especially well-suited to sleepers who are prone to overheating.

This mattress helps to regulate body temperature throughout the night, thanks to a GelTex gel-infused layer. This also minimises the stress that common pressure points, such as hips and shoulders, are put under when lying down.

Sealy’s PostureTech design comprises a series of tempered springs that provide edge-to-edge support from deep within the Silverdale super king-size mattress.

Medium foam and a cosy quilted top layer provide ample cushioning, resulting in a cloud-like effect that will make any sleeper feel comfortably supported.

As an assurance of this mattress's quality, it comes with a 5-year guarantee.

Our mattresses are fully compliant with UK Flammability Standards BS7177

All of our mattresses have been designed to fit and complement our range of solid hardwood Super King-Size bed frames, browse the full range here.

Will It Fit?

Choosing the right piece of furniture for your home is a big decision. Not only does it need to look good and do the job it was made to do, but it also needs to fit.

To fit with your interior style, to fit with your home needs, and most importantly, to fit with the dimensions of your room. If the piece of furniture is near a doorway, which way does the door open? Is the item going to be restricting the route in and out of the room? Is there a radiator on the wall, or a windowsill jutting out that you need to factor in when measuring the item’s height?

Check what you can fit comfortably within your room by looking at the furniture measurements. You can find them in the Dimensions & Assembly section. Note them down and get busy with your tape measure.

The final important measurement to mention, is to ensure your new piece of furniture can fit through your front door when it gets delivered! Most items arrive assembled and boxed. The packaged item dimensions can also be found in the Packaging & Assembly section. Download our Will It Fit PDF, and follow our guide to a smooth furniture delivery.

Very comfortable. I like the top gel layer. I sleep much better than with my old foam mattress. Great value for a quality mattress.
