Why our sleep experts loved it

Disclaimer: This review is written by your friendly sleep expert from a pile of product specs—because I haven’t actually tested the mattress in-store. Here, we’ll judge the M&S Collection 1500 Pocket Spring Medium Mattress based on its construction, listed features, and what sleep science says about medium-firm pocket coil beds.

Comfort and Feel

M&S promises “glorious comfort” from this medium-support, pocket-sprung design. The top layers are pure new wool and white fibre, giving the surface a soft, plush feel. As you lie down, you’ll notice a responsive “give” - more of a springy bounce than sinking in deeply. In short, it’s a balanced feel: neither rock-hard nor marshmallow soft, but nicely cushioned and supportive.

Support and Spinal Alignment

The mattress’s spring system is the backbone (literally) of its support. Up to 1500 individually wrapped coils in a king-size compress only under your body, so heavier zones (hips/shoulders) settle just enough while firmer spring stacks keep your spine level. In practice, this helps prevent sagging under your back or shoulders. The result is neutral alignment: your lumbar region stays lifted and your back is properly supported.

Suitability for Sleep Positions

  • Side: Soft hips and shoulders, medium firmness overall - this should be comfy for most side sleepers. The wool/fibre layers cushion pressure points, and the pocket springs adapt to your curves (similar to how zoned coils work). You get good pressure relief without the bed feeling overly hard.
  • Back: The medium support holds your hips up so your spine stays straight. You’ll sink just enough for comfort under your lumbar area without that hollow-back feeling. Essentially, it should keep you well-aligned when lying on your back.
  • Stomach: This is the riskiest position on a medium mattress. Lighter stomach sleepers will likely be okay, but heavier stomach sleepers may feel their midsection dip too low (arching the back). In general, heavy stomach sleepers often need a firmer bed to keep the hips lifted.

Suitability for Different Body Types

  • Lightweight (<130 lbs): May find the mattress on the firmer side (you won’t compress all the springs), but still cushioned by the wool top. You’ll mostly enjoy support with only moderate sinkage.
  • Average (130-230 lbs): This is the sweet spot. Your weight compresses the mattress enough to activate all the comfort and support layers, giving a balanced feel. In fact, most medium-pocket mattresses are designed with this range in mind.
  • Heavy (>230 lbs): Innerspring mattresses like this often support heavy weights better than pure foam. A heavy person will compress more springs, so the mattress feels softer to them, but the coils still push back. Heavy side/back sleepers should find it adequate, though a heavy stomach sleeper might want something firmer.

Motion Isolation

This is a couple-friendly mattress. Each spring moves independently, so when one person shifts, the motion stays local. M&S even notes it’s “ideal for couples” because of this. In practice, you could change positions at 3 AM and your partner would hardly feel a thing. It’s not 100% like memory foam at absorbing movement, but it’s very effective - most couples will find their partner’s tossing barely registers.

Temperature Regulation and Breathability

This mattress is built to sleep cool. The wool fibres and four side vents facilitate airflow and moisture-wicking. Because there’s no thick foam layer to trap heat, warm air can escape and moisture won’t accumulate. Compared to most all-foam beds (which often hold in heat), this M&S mattress should feel noticeably cooler. In short, you’ll be much less prone to night sweats on this bed.

Materials and Construction

  • Spring Core: Up to 1500 pocketed steel springs in a 27cm mattress. High coil count means precise, zoned support under your body.
  • Comfort Layers: Quilted pure new wool and luxury white fiber. These give a soft, breathable surface. (There’s no memory foam to cradle you; it’s more of a traditional spring feel with a woolly topper.)
  • Anti-Allergy Cover: The quilted cover is treated with ActiPro, resisting dust mites, odors, and allergens. It’s also treated with an antibacterial finish for extra hygiene.
  • Handles & Vents: Four side handles and four silver air vents. The handles make rotating and moving the mattress easier, while the vents keep air circulating through the mattress’s interior.
  • Stitching & Warranty: Three rows of reinforced side stitching for durability, plus a 10-year warranty. Such a long guarantee is rare and signals the mattress is built to last.

Durability and Long-Term Use

The build quality here should last. The sturdy pocket springs and triple-stitched edges mean it resists sagging, and the 10-year guarantee shows M&S stands by its product. If you rotate the mattress periodically (using those handles) as recommended, you should get many years of consistent support with minimal wear.

Ease of Setup and Use

Very straightforward. It arrives ready-made (no assembly required), just unpack, let it expand, and put it on a bed base. You never have to flip it - only rotate it every few months. The only caveat is weight: a king is around 31 kg, so moving it usually takes two people. On the plus side, those four handles make lifting and adjusting it much easier.

Value for Money

At about £499 (single) up to £699 (king), this mattress is reasonably priced for its specs. Given the natural wool filling, 1500 pocket springs, anti-allergy cover, and a 10-year warranty, it’s competitive. It works out to roughly 20p per night over an expected lifespan. You’re getting premium features (like wool and vents) that budget mattresses often skip. Overall, it offers solid value for a midrange budget.

Conclusion: Who Is This Mattress Ideal For?

This medium-firm pocket-spring mattress is a great match for:

  • Combination sleepers (side/back mix) who need both cushioning and support.
  • Allergy sufferers, thanks to the ActiPro cover and natural wool.
  • Couples or anyone who hates partner disturbance, due to excellent motion isolation.
  • Hot sleepers, since the breathable wool and vents keep it cooler than typical foam beds.
  • People who value durability and warranty, as the 10-year guarantee and sturdy build provide peace of mind.

It might be less ideal for:

  • A very heavy stomach sleeper (may need a firmer mattress).
  • Someone wanting an ultra-firm surface (this bed is confidently medium in firmness).
  • Anyone craving a plush memory-foam feel; this is more of a classic spring mattress vibe.

In short, this mattress occupies the “just right” middle ground - a dependable, breathable, medium-comfort bed backed by a decade of confidence. If that sounds like your sweet spot, the M&S 1500 Pocket Spring Medium could be a perfect fit.

Suitability

*Assuming average weight, suitability will vary dependant on body type, use the quiz above for a more tailored guide.
  • Back Sleepers
    ★★★★★
    ★★★★★
  • The amount of support offered from a mattress will vary depending on the firmness of the tension and the type of support layer used. Based on a person of average build.
  • Side Sleepers
    ★★★★★
    ★★★★★
  • If you sleep on your side you typically need a supportive tension that is not too firm, nor too soft. This is because your hips and shoulders need adequate sinkage.
  • Stomach Sleepers
    ★★★★★
    ★★★★★
  • Stomach sleepers need a reasonable amount of tension in the base support layer to adequately offer body contouring and help prevent aches and pains. Results will vary based on your build.

Performance

    ★★★★★
    ★★★★★
  • Mattresses that feature breathable materials help promote airflow and keep you cool making for a more hygienic night's sleep.

  • Certain materials like memory foam can make it difficult to move about on the mattress while you toss and turn. Same too for pillow tops which can create a cloud like sensation which can make manoeuvrability challenging.
  • Stability
    ★★★★★
    ★★★★★
  • Depending on the type of support layer in place can have an impact on stability, edge to edge support and roll together prevention. Pocket springs of a firmer tension will have better stability than open coil soft tension, for example.

Odour
