Why our sleep experts loved it
The Sophie Conran Sanctuary Pocket Wool Mattress & Enhancer is the kind of product that immediately looks the part. It looks and feels properly premium, and the whole concept, a full mattress topped with a removable, double-sided enhancer, is about giving you that plush, hotel style surface comfort without losing support.
I completely get the appeal of it after sleeping on it, and in particular if you are a side sleeper who wants medium-soft feel with plenty of pressure relief. But I also came away with the same sticking point you mentioned, the price is just too high for what you are getting, particularly when you start to compare it to what else is out there at this level.
Construction & Materials
This is a natural-led build, and it shows in the feel. The removable topper is where a lot of the instant comfort comes from, with soft alpaca wool and bouncy mini springs right at the surface. That combination gives you a lovely, buoyant plushness rather than the slow, sinking sensation you get from memory foam.
Underneath, the mattress uses a mix of natural British wool, latex, and bamboo, alongside individually wrapped pocket springs. In practical terms, that means you get a breathable, gently responsive comfort layer over springs that can contour and isolate movement.
Firmness & Feel
If I had to sum up the feel in a sentence, I would call it medium-soft with a noticeable cushion on top, and a supportive core underneath. The topper does a lot of the heavy lifting here, it softens the first contact, takes the edge of pressure points, and adds that slightly springy, lifted comfort that suits side sleeping so well.
What I liked was that it does not feel floppy. Even though the surface is plush, the support from the pocket springs stops you from feeling like you are collapsing into the mattress. For me, it struck that balance where my shoulders could sink in, but my waist still felt held up.
Performance & Support
Support is where the pocket springs earn their keep. Because they are individually wrapped, they respond in smaller sections, so you get more tailored contouring than a traditional open coil system. In real use, that translates to steadier spinal alignment, especially for side sleeping, and a calmer feel when you change position.
It is also a strong performer for partner disturbance. The combination of a springy but damping topper and pocket springs underneath does a good job of absorbing motion, so you are less likely to feel every turn and shuffle from the other side of the bed.
Temperature Regulation
If you are wary of overheating, this is one of the more reassuring premium options. The natural wool, latex, and bamboo are all materials chosen for breathability and moisture management, and in my experience the bed stays more neutral than foam-heavy designs.
The topper adds softness, but it does not trap heat in the way a thick memory foam comfort layer often can. It is the kind of surface that feels cosy rather than clammy.
Practical Features
The headline feature is the removable topper, and I do think it is well thought through. It is double-sided, so you can flip it to refresh the surface, which is useful on a mattress like this where the top layer gets the most wear.
It is also not a light mattress set-up. In day-to-day terms, this is the sort of purchase where I would plan for two people to manoeuvre it, especially if you are taking it upstairs or working around tight corners.
If you are buying at this price point, I would strongly recommend making the most of any sleep-trial or comfort guarantee available, because the feel is premium, but it is also specific, and it is a big outlay to get wrong.
Who It Suits
Side sleepers who want a cushioned surface. The topper and the overall medium-soft feel make it particularly good at taking pressure off shoulders and hips.
Anyone who prefers a natural-led sleep feel and wants something breathable, with less heat build-up than many foam-forward hybrids.
Couples who value a calmer surface and reduced motion transfer. The pocket springs help here, and the feel stays composed rather than wobbly.
Who It Doesn’t Suit
Value hunters or anyone trying to stay within a sensible budget. Even allowing for build quality, this sits at a price level where you can start comparing it to longstanding luxury mattress makers, and it becomes harder to justify.
People who need a firmer feel for front sleeping, or those who simply do not get on with plusher tops. This one is designed to feel indulgent at the surface.
Anyone expecting the topper to justify the price on its own . It improves the feel, absolutely, but it does not fundamentally change the value equation at this level.
Final Verdict
The Sanctuary Pocket Wool Mattress & Enhancer is high quality, and it genuinely feels lovely, especially if you are a side sleeper who wants that medium-soft comfort with real support underneath. The materials and the removable, double-sided topper give it a considered, premium finish, and it performs well for temperature regulation and partner disturbance.
But I cannot get past the pricing. The topper is a nice addition and it does elevate the initial comfort, yet it barely moves the needle when you look at the overall cost. For the money this asks, I expect a clearer value advantage, either through standout specification, a more distinctive feel you cannot easily find elsewhere, or a sharper deal relative to the wider premium market. For me, it is a great mattress, but it is priced like an ultra-luxury one, and that makes it hard to recommend wholeheartedly unless you are completely set on this specific feel.
