Yes, you can get an extra long bed or mattress in Ireland. While standard mattresses are usually around 6’3″ (190cm) long, custom size mattresses and extended-length beds can be made for taller sleepers. These longer beds provide better comfort, proper leg support and improved spinal alignment during sleep.

For taller individuals, standard bed sizes don’t always provide enough length for comfortable sleep. If your feet hang over the edge or you find yourself curling up during the night, it may be time to consider an extra long mattress.

The good news is that custom and extended-length beds are available, so you’re not limited to standard sizes.

What Is the Standard Mattress Length?

In the UK and Ireland, most standard mattresses measure 6’3″ (190cm) long, with Kingsize and Super Kingsize slightly longer at 6′ 6″ (200 cm).

While this suits many sleepers, anyone over approximately 6 feet tall may benefit from additional length for proper support and comfort.

What Is an Extra Long Mattress?

An extra long mattress is typically longer than the standard 6’3″ – 6’6″ length.

These additional inches can make a noticeable difference in comfort, particularly for taller sleepers who need full leg and foot support.

Custom sizes can also be made to match specific room layouts or bespoke bed frames.

Why Mattress Length Matters

Sleeping on a mattress that is too short can lead to:

  • Poor spinal alignment

  • Increased pressure on hips and shoulders

  • Restless sleep

  • Reduced overall comfort

Ideally, your mattress should be at least 4–6 inches longer than your height.

Can You Get a Custom Size Mattress?

Yes. Custom size mattresses are available in Northern Ireland and the Republic of Ireland, including non-standard lengths and widths.

Custom mattresses can be made to:

  • Extra long dimensions

  • Fit antique or bespoke bed frames

  • Suit unusual room layouts

  • Match adjustable or specialist bed bases

At Dalzells Beds, we offer custom size mattresses designed to meet specific length requirements without compromising on support or comfort.

Bed Bases

What About the Bed Base?

If you order a longer mattress, the base must also match the length. Reinforced divan beds and custom-built frames can be manufactured to accommodate extended dimensions.

For taller sleepers, it’s important that both mattress and base are properly aligned to maintain durability and performance.

What Mattress Type Works Best for Extra Long Sizes?

Most mattress constructions can be made in extended lengths, including:

Brands such as Respa, King Koil, Kaymed and others, are able to produce custom size mattresses, allowing taller sleepers to benefit from structured support and Irish craftsmanship in non-standard dimensions.

Try Before You Order

Because custom mattresses are made to specification, it’s important to test the support level in-store before ordering. While the length may change, the comfort feel remains consistent with the model you try.
