The Seventh Heaven Clio 1000 pairs a cushioned medium/soft surface with the steady lift of a pocket-spring mattress. Its natural fillings and two-sided, hand-finished construction give it a traditional feel that is increasingly hard to find at this price. It was most comfortable for back and side sleepers; the softer perimeter was its clearest weakness.

The Clio 1000 at a Glance
| Mattress | Overall Score | Pros | Cons | Best For |
| Seventh Heaven Clio 1000 | 4.1/5 | Medium/soft comfort; responsive pocket springs; breathable natural fillings; two-sided construction | Soft edge when sitting; limited cooling features; too forgiving for many stomach sleepers | Back/side combination sleepers; couples who want moderate motion control without losing bounce; fans of traditional mattresses |
Is the Clio 1000 Worth It?
The Clio 1000 is a strong choice for sleepers who want genuine cushioning without the slow, enveloping feel of thick foam. Shoulders and hips settled comfortably during side sleeping, while the pocket springs kept the pelvis steadier on the back. It also changed position easily and softened most partner movement without feeling flat or lifeless.
The edge is the deciding trade-off. Sleeping close to it felt secure enough, but sitting there for more than a few minutes produced much deeper compression than the center. Choose this mattress for pressure relief and a classic spring response—not for a rigid perimeter or firm stomach-sleep support.
-
Who It’s For
- Side and back sleepers who want cushioning over responsive support
- Couples who prefer some bounce but do not want every turn to cross the bed
- People willing to follow a regular turning schedule for more even wear
-
Who It’s Not For
- Heavier stomach sleepers who need firmer support beneath the hips
- Anyone who regularly sits on the side of the bed and wants a hard, stable edge
- Shoppers seeking the specialized covers or foams found in an actively cooling mattress

How We Evaluated the Clio 1000
We assessed support, temperature control, pressure relief, motion isolation, responsiveness, edge support, and surface consistency. The process combined full-night sleep notes with repeatable measurements, including alignment checks in back and side positions, a 30-minute heat test, partner entry and turning drills, weighted sink measurements, and center-versus-edge compression checks. We used the same base and pillow setup throughout our mattress evaluation.
Our Testing Experience
The 25-cm sample felt soft as soon as we lay down, but the pocket springs engaged before the comfort layers became overly deep. We rated the firmness at 4.5 out of 10. A 44-pound weight sank 1.8 inches at the center, which matched the noticeable shoulder and hip cushioning during side sleeping. On the back, the surface still held the lumbar area evenly instead of letting the pelvis drift too far below the ribs.
Repositioning was easy. The surface recovered 90% of its height in 1.2 seconds after the weight was removed, so turning from side to back did not require an extra push. Partner movement produced a short spring ripple, but the measurable vibration faded in about 1.3 seconds. That is not foam-level isolation, yet ordinary turns and careful exits were rarely disruptive during our couple sleep checks.
Temperature control was adequate rather than exceptional. After 30 minutes, the surface rose 6.2°F in a warm room and remained 2.1°F above its starting temperature ten minutes after we got up. The natural-fill construction allowed some airflow, but hot sleepers should not expect an actively cool surface.
The weakest result came at the perimeter. Under the same seated load, the edge compressed 4.1 inches compared with 2.7 inches at the center. It remained usable for sleeping near the side, but prolonged sitting created a clear slope toward the floor.
-
What we liked
- Pressure relief at the shoulders and hips without a trapped feeling
- Quick rebound that makes position changes easy
- Moderate motion control while preserving a familiar spring response
-
Who it is best for
- Back/side combination sleepers who want a soft top with noticeable support underneath
- Couples who value easier movement more than foam-like motion isolation
- Shoppers who prefer a two-sided mattress and will turn it regularly
-
Where it falls short
- The perimeter compresses substantially during sitting
- The medium/soft feel allows too much hip sink for many stomach sleepers
- The natural fillings breathe, but they do not create an actively cool sleep surface

Where It Excels—and Where It Doesn’t
| Pros | Cons |
| Comfortable medium/soft feel with responsive support | Perimeter compresses under sustained sitting |
| Strong pressure relief without excessive sink | Too soft for many stomach sleepers |
| Two-sided construction allows more even wear | No specialized cooling cover or foam |
| Easy movement and moderate motion control | Residual bounce may bother very light sleepers |

| Overall | 4.1/5 | A comfortable traditional spring mattress for back and side sleepers who can accept a softer edge |
Who Should Choose the Clio 1000?
Choose the Clio 1000 if you want a medium/soft mattress that cushions the body but responds quickly when you move. Its balance works especially well for back-to-side switching. Dedicated stomach sleepers and many heavier sleepers will get better hip support from a firmer model. If temperature is your main concern, treat the Clio as breathable, not actively cooling.
Also consider how you use the edge. The mattress is comfortable across most of its sleep surface, but people who dress, read, or transfer from the side of the bed every day may find the perimeter too soft. The two-sided design also suits owners who are happy to turn a mattress regularly; shoppers who want a no-maintenance sleep surface should look elsewhere.

What to Know Before You Buy
The same softness that relieves pressure can let the hips dip too far during stomach sleeping. Edge support is also below average for prolonged sitting, even though sleeping near the side feels stable enough. Finally, the mattress relies on breathable materials rather than cooling fabric or gel foam, so people who regularly overheat may need a more specialized option. The made-to-order wording deserves attention as well: confirm cancellation and return eligibility for your chosen size before paying.
How It Compares With Similar UK Mattresses
The Seventh Heaven Eros 1000 is the closest alternative. It uses the same 1,000-spring count in king size, natural cotton-containing fillings, 25-cm depth, two-sided construction, and 10-year guarantee. Its medium feel is the meaningful difference. Choose the Eros if the Clio sounds appealing but you want a little less hip and shoulder sink.
The Seventh Heaven Victoria sits in a nearby price range but changes the feel more substantially. Its medium/firm open-coil design is flatter and more resistant than the Clio's medium/soft pocket-spring surface. The Victoria makes more sense for stomach sleepers, frequent edge sitting, or a guest room; the Clio is the better fit for side-sleep pressure relief and reduced partner disturbance.
Getting the Best From the Clio 1000
- Allow several nights for the fillings and your body to settle before making a final judgment on firmness.
- Keep pillow height consistent when switching between back and side sleeping.
- Use a thin, breathable protector if you sleep warm; a thick waterproof pad can trap more heat.
- Add mattress turning to your regular care schedule so both sides wear evenly.
- Place it on a level, supportive base that meets the retailer's requirements.
FAQs
How does the firmness feel in everyday use?
It feels medium/soft, or about 4.5 out of 10 in our assessment. The top cushions the body immediately, then the pocket springs add support as weight settles.
Is the Clio 1000 a good choice for couples?
Yes, if both sleepers like a softer feel. It settles partner movement well for a spring mattress, although a brief ripple remains after larger turns.
Does the Clio 1000 sleep cool?
It sleeps temperature-neutral for most people rather than noticeably cool. The natural fillings breathe, but there is no dedicated cooling cover or foam layer.
Does the Clio 1000 need to be turned?
Yes. It is a two-sided mattress, so regular turning helps distribute wear and keep the surface consistent.
Who should avoid the Clio 1000?
Most dedicated stomach sleepers, people who need a very firm perimeter, and anyone seeking active cooling should consider another mattress.
