Woolroom's Beulah 1000 No-Turn Mattress is a lovely, honest wool mattress built around a compromise. Wool lasts longest when both sides of a mattress get slept on, and this one has only one. Most of the price goes on that wool, not the springs. Buy it if natural fillings come first for you and lifespan second. Pass on it if you want a wool bed to go the full distance.
A wool bed you can't turn settles on the one side you sleep on
At its heart is a generous layer of Wool ID traceable British wool, with three rows of side-stitching round the border and no synthetic foam, glue or chemical fire retardants anywhere in it. That's a clean, breathable build, and I like it a lot.
The trouble is what wool does under a body. Natural fillings pack down where you lie, and on a two-sided mattress you share that out by turning it. On a no-turn bed every night lands on the same side, so the settling has nowhere else to go. No-turn is a saving the trade dressed up as a feature, and it costs most on a wool mattress, the kind that would otherwise last longest.
1000 springs is light for the money, so price a Hypnos you can flip
Woolroom counts 1000 pocket springs for a king, in one regular tension, and the mattress is about 24cm deep in a double or king. For this money that's a light count, though 1000 pocket springs still do a fair job.
So price it against the Hypnos Burford Ortho Comfort, which you flip and rotate with the seasons: 1200 pocket springs, natural fibre fillings, 27cm, medium to firm, with turning handles. If you want to stay with Woolroom's wool, the Woolroom Hebridean 3000 adds 2000 micro springs to 1000 pocket springs, and I'd count the micro springs as comfort rather than support. Compare them in the same size before you decide, and if natural fillings are the point, price Harrison Spinks too, whose natural-filled mattresses carry far more pocket springs.
Owners find it cooler, while a few feel it settling
Temperature is where owners are happiest. Several find it cooler than what they had, one of them coming off a Tempur, and one says it's the first mattress that hasn't made them overheat. One owner still couldn't get cool enough in summer. Wool suits a body like mine, cold feet in winter and hot everywhere else, because it copes with both. A couple call it on the firmer side, and one says it started soft and firmed up as it settled.
The complaints are the no-turn compromise showing up. One owner, five months in and rotating as told, found pressure at the hip and felt themselves rolling towards the middle. A topper fixed the pressure but not the roll. Another can see a dip forming and can't rotate it alone. One found the weekly rotating and airing in the first three months a bit of a faff.
Woolroom's sleep trial only applies if you buy one of its wool mattress protectors with the mattress, so put one in the basket if you want that way out.
What to buy instead
If you want wool that lasts, buy a two-sided mattress, and price the Hypnos Burford Ortho Comfort first. If no-turn suits your back and your routine, the Beulah is a nicely made bed, and I'd still wait for a good price on it.
