Key benefits

Key Benefits of the Jay-Be Ryze Memory Comfort Quilted e-pocket 1000 King Size Mattress in a Box

  • Proper space for two: At 75cm each for two people sharing, you get room to change position in the night without nudging your partner awake.
  • Less partner disturbance: If one of you gets up hours before the other, the extra width means an early alarm and a quiet exit are far easier to sleep through.
  • Length for taller sleepers: The UK king is 10cm longer than the UK double, which matters more than width if one of you is over six foot.
  • Boxed delivery in a big size: It arrives compressed and rolled, so getting a king size mattress up a narrow staircase is a one-trip job rather than a wrestling match.
  • Room for a bed-sharing pet: If the dog treats the bed as its own, the extra 15cm over a UK double gives everyone back some territory.

Who should buy the Jay-Be Ryze Memory Comfort Quilted e-pocket 1000 King Size Mattress in a Box?

This size suits you if...

You share the bed every night and a double has started to feel cramped, you and your partner keep different hours and want to stop disturbing each other, or one of you is tall enough to appreciate the 200cm length. Your bedroom should measure at least 2.7m x 2.9m for the bed to sit comfortably.

Consider another size if...

Your bedroom falls short of the 2.7m x 2.9m we suggest for a UK king, which is common in newer builds once wardrobes go in. We'd recommend the UK double instead, which needs at least 2.6m x 2.8m.

FAQ's

Frequently Asked Questions About the UK King

Is the Jay-Be Ryze e-pocket 1000 UK king big enough for a couple?

Yes, comfortably. At 150 x 200cm you get 75cm each for two people sharing, noticeably more than a UK double offers. Across the sizes this mattress comes in, the UK king is the one built for couples who want to stop negotiating over space.

What room size do I need for the Jay-Be Ryze in a UK king?

We suggest at least 2.7m x 2.9m, which leaves enough space to walk round the bed and open drawers. That figure is our own guidance rather than the manufacturer's, so measure your room before ordering, particularly in a new build where wardrobes eat floor space quickly.

Does the Jay-Be Ryze e-pocket 1000 come in a super king?

No. The UK king, at 150 x 200cm, is the largest size this mattress is made in. If you need more width than that, you'd have to look at a different mattress altogether, but for most couples the king's 75cm each is generous.

Is the UK king Jay-Be Ryze long enough for a tall sleeper?

At 200cm, the UK king is 10cm longer than the UK double, and that extra length is often the real reason taller people size up. If one of you is over six foot and wakes with feet hanging off the end, this is the size to pick.
