Summer is when a lot of our customers are furnishing a spare room, a student let, or a smaller second bedroom, and the question we get asked most often at this time of year is whether a small double is actually big enough for an adult to sleep on comfortably. It is a fair question, and the honest answer depends on who is using the room and how often.
For comparison, our Artisan Naturals is £2,180 in king size, which shows the range available once you move up from a small double into something more substantial for a main bedroom.
A few things worth thinking through before you buy for a spare or second room:
📐 A small double suits a single adult sleeper well, but two adults sharing regularly will usually find it tight for long term comfort
🎓 For a student room or occasional guest use, a small double is often the sensible, space efficient choice
🛋️ If the room could eventually become a main bedroom, it is worth measuring for a full double or king size now rather than buying twice
🧹 Consider how the mattress will be used day to day too. A firmer feel tends to suit multi purpose rooms doubling as a study or sitting space
We have written an honest guide covering exactly who a small double suits and who should stretch to something larger.
