Key benefits

Key Benefits of the Relyon Hand Crafted Serenity King Size Mattress

  • Real space for two: At 75cm each for two people sharing, both of you get room to turn over without negotiating for it.
  • Less disturbance across a wider bed: Pocket springs compress independently, which means a partner getting up at 5am registers far less, and the extra width of a UK king adds physical distance too.
  • Extra length for taller sleepers: At 200cm long, the UK king gives 10cm more than the UK double, so anyone approaching 6ft stops sleeping diagonally or hanging off the end.
  • Sleep right to the edge: Two rows of hand side stitching firm up the sides, so the full 150cm width is usable rather than a soft border you avoid.
  • A sensible footprint: The UK king fits most main bedrooms, we suggest at least 2.7m x 2.9m, without the floor space a UK super king demands.

Who should buy the Relyon Hand Crafted Serenity King Size Mattress?

This size suits you if...

You share the bed every night and a double has started to feel cramped, especially if one of you keeps different hours and the other feels every exit and entrance. It also makes sense if one partner is approaching 6ft and needs the 200cm length, or if a dog has quietly claimed a strip of the mattress and you want your share back.

Consider another size if...

Your bedroom falls short of our suggested 2.7m x 2.9m minimum, or you sleep alone. We'd recommend the UK double instead, which needs at least 2.6m x 2.8m of room space.

FAQ's

Frequently Asked Questions About the UK King

Is a UK king Relyon Serenity big enough for a couple?

Comfortably, for most. Two people sharing get 75cm each, which is 7.5cm more per person than the UK double offers. Combined with pocket springs that move independently, it suits couples where one person shifts around or gets up earlier. If you both sprawl, the UK super king gives 90cm each, but it needs a bigger room.

Will the Relyon Hand Crafted Serenity king suit a tall sleeper?

The UK king is 200cm long, 10cm longer than the UK single, small double and double. For anyone approaching 6ft, that added length is often the real upgrade, more so than the width. Relyon doesn't publish a depth for this mattress, so check bedding fit with the retailer before buying.

What room size do I need for the Serenity in a UK king?

We suggest at least 2.7m x 2.9m, with 3.2m x 3.2m feeling comfortable once wardrobes and bedside tables are in. New build master bedrooms can be tighter than they look on the plan, so measure with furniture in place. If you're short of space, the UK double needs at least 2.6m x 2.8m.

Should I choose the king or super king Serenity?

The UK super king is 30cm wider than the UK king, at 90cm each for two sharing rather than 75cm, and both are the same 200cm length. The UK king is the better fit for most rooms; the UK super king needs at least 3m x 2.9m. If your room takes it and you both spread out, size up.

Where can I buy the Relyon Serenity in a UK king?

Compare the retailers listed on this page; the prices shown are updated as retailers change them. Do check the small print wherever you buy, because extras like sleep trials are set by the retailer rather than Relyon, so terms can differ between listings for the same UK king mattress.
