Key benefits
- Fits a typical bedroom: We suggest a room of at least 2.6m x 2.8m, so the UK double suits most British bedrooms while still leaving space to walk around the bed.
- Room for bedside tables: In a room around 3m x 3m, a UK double usually leaves space for a bedside table on each side, so neither of you has to keep your phone on the floor.
- Steady support for two: The firm comfort grade gives you both a solid, even surface, which suits couples who sleep on their backs, although a lighter partner who sleeps on their side may want more cushioning.
- Easy bedding: Double sheets are sold almost everywhere and a 200 x 200cm double duvet fits, but check that fitted sheets are deep enough for a 33cm mattress.
- A proper guest bed: In a spare room, the UK double gives visiting couples a real shared bed with natural wool filling, without taking over the whole floor.
This size suits you if...
You share the bed with a partner in a typical UK bedroom of at least 2.6m x 2.8m, you'd like bedside tables on both sides of the bed, or you're setting up a guest room where couples come to stay.
Consider another size if...
You and your partner each want more than 67.5cm of width. We'd recommend the UK king instead, which gives 75cm each; allow at least 2.7m x 2.9m for the UK king.

FAQ's
Is the Flaxby Woolcroft 3500 double big enough for two people?
For most couples, yes. The UK double gives you each 67.5cm of width, the traditional amount for sharing in Britain. If one of you sprawls, or you're both broad-shouldered, you might find it a little snug: the UK king gives 75cm each, so the UK double gives 7.5cm less per person.
What size bedroom do I need for a UK double mattress like the Woolcroft 3500?
We suggest at least 2.6m x 2.8m. That lets the 135 x 190cm mattress fit with room to get in and out. Around 3m x 3m is the comfortable norm, and gives you a better chance of fitting a bedside table on each side plus a wardrobe or chest of drawers.
Will a 33cm deep double mattress fit up narrow stairs?
The Woolcroft 3500 is 33cm deep and 135cm wide in a UK double, so turning stairs in older terraces and tight new build landings can be awkward. Measure the narrowest turn and any low ceiling over the stairs first, then compare the retailers listed on this page and ask how the mattress arrives.
Should I get the Woolcroft 3500 in a UK double or UK king?
The UK double is 15cm narrower and 10cm shorter than the UK king. Choose the UK double if your room is closer to 2.6m x 2.8m. If you have at least 2.7m x 2.9m and either of you is tall or a restless sleeper, the UK king gives more space.
What bedding fits a Flaxby Woolcroft 3500 UK double?
Standard double sheets fit the 135 x 190cm surface, and a 200 x 200cm double duvet covers it. The one thing to check is fitted sheet depth: the mattress is 33cm deep, so look for a deep fitted sheet that grips the corners rather than a shallow one that pops off overnight.
