Single Mattresses (3ft)

Standard 3ft Single Mattress dimensions ( 190cm x 90cm explained)

While a single mattress might be on the small end of the mattress size scale, this doesn’t mean they’re not suitably big enough for sleepers of all heights. Measuring 6ft3” by 3ft (or 190cm x 90cm), a 3ft single mattress is more than roomy enough for a single adult, and provides plenty of extra room if acting as a kids mattress.

To put it another way, a single mattress is the optimum bed choice for when space is tight or your budget is limited, ensuring you can still get a great night’s sleep, regardless of your bedroom size.

Finding the Right 3ft Single Mattress for Your Needs

Not all single mattresses are created equal. Depending on who the sleeper is, your priorities for support and durability will change:

• For Children & Teenagers: Growing bodies need consistent support. Our Kids Mattresses are often designed with breathable materials to regulate temperature. If you are shopping for a bunk bed, ensure you choose a bunk bed mattress with a depth of no more than 16cm for safety.

• For Adults: For a primary bed, we recommend a high-quality pocket sprung single mattress. These provide individual support for your pressure points and greater longevity than basic open-coil models.

• For Guest Rooms: A hybrid mattress is often the best choice here, as it provides a "crowd-pleasing" feel that suits both side and back sleepers.

Expert Advice: Pocket Sprung vs. Memory Foam

As industry specialists since 2003, our Sleep Experts have helped thousands of customers navigate these choices:

• Pocket Sprung: Ideal for those who prefer a traditional, responsive feel with plenty of airflow.

• Memory Foam: Perfect for joint relief. The foam contours to your shape using body heat, which is excellent for those with aches and pains.

• Firmness Guide: Generally, side sleepers should opt for Medium-Soft, while back or front sleepers require a Medium-Firm to Firm feel to maintain spinal alignment. See our full Mattress Firmness Guide for more details.

Can I use my existing bed frame?

Yes, as long as it is a standard UK 3ft Single size and in good structural condition.

Expert Tip: Check the slats. If the gaps between your slats are wider than 75mm (3in), it can cause the mattress to sag and may void the manufacturer’s warranty. If your base is aging, browse our Single Divan Bases or Single Bed Frames for a fresh start.
