Key benefits

Key Benefits of the Millbrook Sovereign Natural Pillow Top Single Mattress

  • Leaves space in a small bedroom: At 90 x 190cm, we suggest allowing at least 2.1m x 2.8m, which leaves floor space for a desk or wardrobe in a child's room.
  • Zoned support for one person: The seven-zone springs shape support to different parts of your body, which means a solo sleeper gets the same targeted support as the larger sizes offer.
  • The easiest size to get upstairs: Yes, it arrives flat rather than rolled, but the UK single is the narrowest version, so a tight staircase or loft conversion is usually less of a problem.
  • A proper bed for guests: Two UK singles side by side let a spare room sleep friends or siblings separately, each on their own cushioned pillow top.
  • Everyday bedding fits: Standard single sheets and a single duvet (135 x 200cm) fit, so you won't need to hunt for anything specially sized.
  • Simple to look after: It's single-sided with turning handles, which means the occasional rotation is a quick one-person job on a UK single.

Who should buy the Millbrook Sovereign Natural Pillow Top Single Mattress?

This size suits you if...

You're furnishing a child's or teenager's room where a desk and wardrobe still need their share of the floor, or you're setting up a spare room that doubles as a study and want guests to sleep on something properly cushioned.

Consider another size if...

You share the bed, or simply want room to spread out at night. We'd recommend the UK double instead, which is 45cm wider; we suggest at least 2.6m x 2.8m for the UK double.

FAQ's

Frequently Asked Questions About the UK Single

Can I use the Millbrook Sovereign UK single on a bunk bed or mid sleeper?

Check your frame first. The Sovereign is 31cm deep, which is deeper than many mattresses designed for raised frames. Bunk and mid sleeper makers usually set a maximum mattress depth so the guard rail stays high enough above the sleeper. If 31cm exceeds your frame's limit, a slimmer mattress would be the safer option for that bed.

What size room do I need for a UK single Millbrook Sovereign?

We suggest allowing at least 2.1m x 2.8m of floor space. That gives you enough room to walk around the bed and open drawers or a wardrobe, which matters most in a child's bedroom or a box room where every bit of floor is already spoken for.

How big is the Millbrook Sovereign Natural Pillow Top single in feet?

The UK single measures 90 x 190cm, which is 3ft x 6ft 3in. It's the standard UK single size, so it should fit any frame sold as a UK single, although the 31cm depth is worth checking against bunks and cabin beds.

Will a single Millbrook Sovereign fit up narrow stairs to a loft conversion?

It arrives flat rather than rolled and boxed, so it won't fold into a small parcel. Even so, the UK single is the narrowest version at 90cm wide, which makes tight landings and steep loft stairs much easier than with a larger size. Measure your stairwell and any turns before ordering.

Is a UK single Millbrook Sovereign long enough for a tall teenager?

At 190cm long, the UK single suits most teenagers and adults. If your teenager is already tall, or still growing fast, their feet may reach the end. The UK king is 10cm longer, although it needs far more room: we suggest at least 2.7m x 2.9m for the UK king.
