Large Single Mattress Protectors – 3ft 6 Bed Size

Mattress Protectors for 3ft 6 Large Single Beds

A Large Single mattress is wider than a standard UK single, so an ordinary single mattress protector will normally be too narrow. Choosing a protector made for the correct mattress dimensions gives better coverage and helps it stay securely in place.

Our Large Single mattress protectors are designed for mattresses around 3ft 6in (107cm) wide, with different lengths available for specialist and extra-long beds.

What Size Large Single Mattress Protector Do I Need?

Large Single mattresses can vary in length, so we recommend measuring your mattress before ordering. Common 3ft 6 sizes include:

• 3ft 6 x 6ft 3in – approximately 107 x 190cm
• 3ft 6 x 6ft 6in – approximately 107 x 200cm
• 3ft 6 x 7ft – approximately 107 x 213cm

Measure the width, length and depth of the mattress rather than relying only on the bed description. This is particularly important for adjustable, imported or specialist beds.

Quilted Large Single Mattress Protectors

A quilted mattress protector adds a soft protective layer between your fitted sheet and mattress. It helps protect against everyday wear while adding a little extra comfort.

Quilted protectors are a good choice if you mainly want to keep the mattress clean and protected without adding a waterproof layer.

Waterproof Large Single Mattress Protectors

For greater protection, choose a waterproof Large Single mattress protector. These are ideal where protection from spills, accidents or moisture is important while still allowing you to use bedding made for your correct 3ft 6 mattress size.

Our breathable waterproof protectors are designed to give practical protection without the bulky feel associated with older waterproof bedding.

Large Single Mattress Protectors for Deep Mattresses

Mattress depth is just as important as width and length. If your mattress is deeper than average, or you use a mattress topper, a shallow protector can pull away from the corners.

Selected Large Single mattress protectors are available in different depth options, allowing you to choose a better fit for deeper mattresses.

Are Large Single and Three Quarter Beds the Same Size?

The terms Large Single, 3ft 6 bed, three quarter bed and sometimes super single are often used for similar bed sizes. However, the exact dimensions are not always identical.

If your mattress is around 107cm wide, this Large Single range is a good place to start. Always check the exact mattress length and depth before ordering.

Complete Your Large Single Bedding

Once your mattress is protected, you can complete the bed with our Large Single Fitted Sheets, Large Single Duvet Covers and other products from our Large Single Bedding collection.
