Seventh Heaven Artemis 2000 Review

Yes—if you want a traditional, two-sided mattress that feels supportive without becoming hard. The Artemis 2000 kept the hips level during back sleeping, allowed enough shoulder give for short stretches on the side, and made position changes easy. Its natural-fill comfort layers also released heat faster than the dense all-foam beds in our comparison set.

The choice is less convincing for strict side sleepers who need deep cushioning or anyone who regularly sits at the edge. The perimeter works well enough for sleeping, but it compresses more than a reinforced edge rail. This is a responsive, well-balanced mattress, not a plush or motion-deadening foam mattress.

• Best match

  • Back and back/side combination sleepers who want medium support
  • Hot sleepers who prefer wool and other breathable fibers over dense foam
  • Couples who want easy movement and can accept a mild spring response

• Look elsewhere if

  • You sleep only on your side and need pronounced shoulder and hip cushioning
  • You rely on a very firm edge for sitting or getting out of bed
  • You want the slow, close contour of memory foam

We used a 24 cm sample for 21 nights across regular weeknights and weekends, then flipped and rotated it to check whether both sleeping surfaces felt alike. Our mattress testing process covered support, cooling, pressure relief, motion isolation, responsiveness, and edge support. We also compared center and edge compression, tracked surface temperature, and timed how quickly the comfort layers recovered after a load was removed.

The Artemis felt like a true medium, about 6/10 on our firmness scale. On the back, the hips settled just enough to ease tension without pulling the lower spine out of line. Moving onto the side produced more pressure at the shoulder than a deep pillow top would, but it remained comfortable for shorter periods. A 44-pound load compressed the center by 3.4 cm and the edge by 5.0 cm, which matches the secure middle and softer perimeter we felt when lying and sitting.

Temperature control was a clearer strength. The surface rose from 20.8°C to 24.2°C after 30 minutes of contact, then cooled to 21.6°C ten minutes after the tester got up. The mattress also recovered 90% of its height in 1.2 seconds after the load was removed, so rolling from side to back never required a push with the arms. Partner turns created a brief spring tremor, but it settled in under a second and did not move the entire bed.

Flipping the mattress produced the same medium response on the second side. That consistency matters here: using both surfaces should spread compression through the natural fillings instead of concentrating wear in one top layer.

• What we liked

  • The center held the hips in a neutral position without feeling rigid
  • Natural fibers released heat quickly and never developed a clammy feel
  • Fast surface recovery made turning and getting up straightforward

• Who it is best for

  • Back sleepers and people who alternate between their back and side
  • Couples who prefer a responsive bed to a deep foam cradle
  • Shoppers who will follow a regular flip-and-rotate schedule

• Where it falls short

  • The edge compresses too much to feel braced during prolonged sitting
  • Strict side sleepers may want more depth under the shoulder and hip
  • People who want almost no partner disturbance will prefer a less buoyant design

Choose the Artemis 2000 if you spend most of the night on your back but regularly move onto your side. It gives the hips firmer support than the shoulder, responds immediately when you turn, and sleeps cooler than a foam-heavy bed. It also makes sense if you value a two-sided design and are willing to flip it.

Choose a different mattress if side-sleeper cushioning or a firm sitting edge matters more than easy movement. In the same general UK price band, the John Lewis Waitrose Wool 1600 feels slightly firmer and is simpler to maintain because it is one-sided. The John Lewis Waitrose Wool 1800 Pillowtop costs a little more but gives the shoulder and hip a deeper, softer landing.

The main limitation is not support but cushioning depth. The surface yields at the shoulder and hip, yet strict side sleepers may still feel pressure during a full night. The perimeter also compresses noticeably while sitting, so people who use the edge to dress or stand may want a reinforced design. Finally, the made-to-order purchase has a stated 2–3 week lead time and does not offer the forgiving change-of-mind return policy common with boxed mattresses.

John Lewis Waitrose Wool 1600: This is the closest verified UK price-band alternative. Its medium-firm feel is a better match for shoppers who want less give, and its single-sided build only needs rotation. The Artemis offers more springs in king size, two usable surfaces, and more bespoke sizing options, while the John Lewis model has a simpler mainstream retail and comfort-exchange path.

John Lewis Waitrose Wool 1800 Pillowtop: Choose this model if the Artemis sounds too shallow at the shoulder. Its medium pillow top adds more cushioning and its 30 cm profile feels fuller, but it is single-sided and includes recycled comfort fibers alongside British wool. The Artemis remains the better fit for buyers who prioritize a turnable build, hand side-stitching, and a more responsive traditional surface.

• Allow several nights for the fillings to settle before judging the final feel.
• Flip and rotate it regularly so both sides wear evenly.
• Use breathable sheets and a thin protector rather than a thick foam pad if cooling is a priority.
• If only the shoulder needs more give, try a thin topper before replacing the mattress with a much softer model.
• Place it on a stable foundation that supports the full width of the spring unit.
