Key Benefits of the Flaxby Platinum Lunar Single Mattress

  • Fits compact rooms comfortably: At 90cm wide it needs only around 2.1m x 2.8m of floor space by our guidance, leaving room for a desk or wardrobe alongside.
  • Sleep right to the edge: Three rows of hand side-stitching firm up the perimeter, which matters more on a 90cm mattress where every centimetre of usable width counts.
  • Natural temperature control for one: Wool, silk and cashmere fillings regulate warmth naturally, useful for teenagers and warm solo sleepers who cannot roll to a cooler patch on a narrow bed.
  • A tension chosen for the sleeper: Soft, medium and firm options mean a lighter child or teen can have a gentler feel than an adult would pick.
  • Easy, cheap bedding: Standard single sheets and a 135 x 200cm single duvet fit, and the 27cm depth works with ordinary fitted sheets.

Who should buy the Flaxby Platinum Lunar Single Mattress?

This size suits you if...

You're a solo adult sleeper who wants natural materials and traditional construction in the standard one-person size, or you're buying a long-term bed for a teenager and would rather pay once for something that lasts. It also suits a spare room that doubles as an office, where a 90cm footprint leaves the desk wall free.

Consider another size if...

You share the bed, even occasionally, or you're a solo sleeper who likes to sprawl. We'd recommend the UK double instead: it is 45cm wider than the UK single, the same length, and needs a room of at least 2.6m x 2.8m by our guidance.

FAQ's

Frequently Asked Questions About the UK Single

What size is the Flaxby Platinum Lunar UK single?

It measures 90 x 190cm, which is 3ft x 6ft 3in, the standard UK one-person size. That makes it the same length as the UK small double and the UK double, and 10cm shorter than the UK king.

Will the Flaxby Platinum Lunar single fit in a small bedroom?

Usually, yes. We suggest allowing at least 2.1m x 2.8m of floor space, which most box rooms, student rooms and loft conversions can manage. In a room under a sloped ceiling, the narrow 90cm footprint lets you tuck the bed along the low wall and keep standing height elsewhere.

Can I use the Flaxby Platinum Lunar UK single on a bunk or mid sleeper?

Check your frame's maximum mattress depth first: this mattress is 27cm deep, which is more than many raised frames allow for guard rail safety. It is also dual-sided and needs flipping to wear evenly, which is awkward on a bunk. For a child's raised frame, a shallower single is often the more practical choice.

Is a UK single big enough for an adult to sleep on every night?

It is the standard adult one-person size, and the firm side-stitched edges here mean you can use the full 90cm width without feeling perched. If you like to spread out, the UK small double is 30cm wider at the same length and needs a room of at least 2.4m x 2.8m by our guidance.

Does the Flaxby Platinum Lunar UK single suit a guest room?

It fits the role well, particularly where two single beds serve visiting family or friends better than one larger bed. Single bedding is the cheapest and most widely stocked of any size, which keeps a rarely used room easy to run. It is a premium spend for occasional guests, so weigh how often the room is slept in.
