Marlborough Mattresses Details

For king-size comfort and a cool sleeping surface, the Marlborough 5000 uses foam and pocket springs to give independent support – with no ‘roll together’ – and strength across the whole mattress, even at the edges. Finished in a luxurious material that also helps regulate temperature with its capillary action, and you’ll be set for comfortable sleep.

Our mattresses will work with any bed frame of the right size, but we have over 20 ranges of king-size frames that the Marlborough 5000 will suit – in a style that will suit you.

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 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.
