Romantica Bamboo Memory King Size Mattress
The Romantica Bamboo Memory Mattress pairs a 1.5cm layer of memory foam with traditional open coil springs, which means you get a little body-cradling softness over a firmer, familiar spring feel rather than the deep sink of an all-foam bed.
- Gentle cradling at shoulders & hips
- Bouncy, traditional sprung feel
- Double-sided, flip it to last longer

Layer Details
Memory Foam
A 1.5cm layer of memory foam sits at the surface, which means gentle cradling around your shoulders and hips rather than a deep hug. It takes the edge off the springs below without the sunken feeling thicker foam layers can create.
Traditional Open Coil Springs
Interlaced springs joined in a lattice design provide the support core. This gives the mattress a connected, slightly bouncy feel, though it also means movement can transfer across the bed more than with pocket springs.

Key benefits
- More room each than a double: You each get 75cm, which is 7.5cm more per person than a UK double, so elbows and knees meet less often during the night.
- Extra length for taller sleepers: At 200cm long, the UK king is 10cm longer than the UK double, which means a partner over six foot is less likely to have their feet hanging off the end.
- A little distance from a restless partner: The extra width lets you lie slightly further apart, which softens the bounce from the lattice springs when one of you turns over, although you'll still feel some movement.
- Room to shift and prop up: Pregnancy pillows, or a stack of cushions while you recover from surgery, fit more comfortably without pushing your partner towards the edge.
- The largest size in this range: Romantica makes this mattress up to a UK king, so it's the size to choose if you want the most space this model offers.
This size suits you if...
You share the bed every night and have started to feel squeezed in a UK double, or one of you is over six foot and keeps running out of length. It also suits you if one of you gets up hours before the other and you'd like a little more distance between you.
Consider another size if...
Your bedroom falls short of our suggested 2.7m x 2.9m once wardrobes are in. We'd recommend the UK double instead, which needs at least 2.6m x 2.8m.

FAQ's
Will a UK king Romantica Bamboo Memory Mattress stop me feeling my partner move?
It will help a little. You each get 75cm, compared with 67.5cm in a UK double, so there's more space between you. The interlaced open coil springs are joined together, though, and they pass movement across the bed more than pocket springs do. If your partner is very restless, the extra width alone won't cure it.
Is the Romantica Bamboo Memory Mattress UK king long enough if you're over 6ft?
It's 200cm long, or 6ft 6in, which is 10cm longer than the UK double. For a partner over six foot, that length is often the upgrade that matters most, because it gives room for your pillow and your feet without leaving you pressed against the footboard.
What size bedroom do I need for a Romantica UK king mattress?
We suggest at least 2.7m x 2.9m, and 3.2m x 3.2m is more comfortable. New build master bedrooms can feel smaller than their floor plan once fitted wardrobes are in, so measure the clear floor space first, then allow room to walk around both sides of the bed.
Should I get the Romantica Bamboo Memory Mattress in a UK king or a UK double?
Choose the UK king if you share and want more space: it's 15cm wider and 10cm longer than the UK double. The UK double makes more sense in a tighter room, since we suggest at least 2.6m x 2.8m for it, compared with 2.7m x 2.9m for the UK king.
Is a UK king Romantica mattress big enough for two people and a dog?
A UK king gives you 75cm each before the dog arrives, and a dog that sleeps across the middle will eat into that quickly. Romantica doesn't make this mattress in a UK super king, so if a pet regularly shares the bed, the UK king is the most space this model can give you.
