iDealBed’s lineup mixes all-foam models with cooler-sleeping hybrids, then moves into thicker, more layered luxury builds. In our hands-on testing, the main trade-off was clear: the springier models carried more movement, while the foam-heavy option stayed quieter but slower to respond.

Testing Team Takeaways

How We Tested It
We used the same routines on all four mattresses: full-night sleep, pre-sleep reading, and morning edge-sitting. We scored Support, Cooling, Pressure Relief, Motion Isolation, Responsiveness, Edge Support, and Durability based on what we observed in our actual testing.
iDealBed: Our Testing Experience
G4 Nova Luxury Memory Foam Mattress
Our Testing Experience:
The G4 Nova felt calm and steady in our nightly movement checks. You sink in gradually, which helped with pressure relief, but it also makes turning slower. The edge is fine for sleeping near it, though sitting feels softer than on the hybrids.
What we liked
- Very low motion transfer in our partner-movement tests
- Consistent contouring through shoulders and hips
- Cooler first-contact feel from the cover
Who it is best for
- Sleepers who want a foam-hug feel
- Couples who are sensitive to movement
Where it falls short
- Slower response when changing positions
- Softer edge for sitting
Pros & Cons:
| Pros | Cons |
| Strong motion dampening | Slower to respond when rolling |
| Cool-to-touch cover feel | Softer edge than coil-based beds |
| Comfortable contouring for joints | Less lift for people who prefer bounce |

S4 Nebula Luxury Hybrid Mattress
Our Testing Experience:
The Nebula felt cooler and more immediately supportive under the hips than the all-foam option. In our edge-sitting routine, the perimeter stayed stable. You still feel more coil lift and more movement than on the Nova, which is typical for hybrids.
What we liked
- Cooler, airier feel in our overnight tests
- Coils helped keep hips level
- Steady perimeter for sitting
Who it is best for
- Hot sleepers who want cooling plus lift
- Back sleepers needing stronger hip support
Where it falls short

iQ5 Luxury Hybrid Mattress
Our Testing Experience:
The iQ5 delivered the softest surface feel in this group without losing support underneath. In our side-sleep checks, it was the most forgiving through the shoulder and outer hip. You’ll still feel more motion than on the Nova, but it didn’t feel unstable in our tests.
What we liked
- Strong pressure relief for side sleeping
- Support showed up before hips could dip
- Steady edge feel for a plush hybrid
Who it is best for
- Side sleepers wanting a softer feel
- Back sleepers who need cushioning
Where it falls short
- Not the firmest for stomach sleeping
- More motion carry than all-foam
Pros & Cons:
| Pros | Cons |
| Luxury plush comfort with hybrid support | Can feel too soft for heavier stomach sleepers |
| 120-day sleep trial and 10-year warranty | Motion isolation not as strong as all-foam |

iQ7 Ultimate Luxury Pillow Top Mattress
Our Testing Experience:
The iQ7 felt taller and more layered, with a cushioned pillow-top surface that rebounded quickly. In our side-sleep checks, it eased pressure while still feeling supportive. We also measured more motion carry than on the foam-heavy model, which is expected with a buoyant hybrid build.
What we liked
- Plush pillow-top cushion with fast recovery
- Stable edge feel for sitting
- Strong pressure relief without feeling mushy
Who it is best for
- Combo sleepers who want plush comfort with rebound
- Fans of thicker, luxury pillow tops
Where it falls short
- More motion carry than all-foam
- Plush feel may be too soft for stomach sleeping
Pros & Cons:
| Pros | Cons |
| Approx. 17" pillow-top hybrid build | Less motion isolation than all-foam |
| Micro-coils, latex, and gel foams for layered support | Plush feel can be too soft for strict stomach sleepers |
| Full edge foam encasement and high coil counts by size | Higher price tier than the 4 Series |
Details:
- Price: $1,699.00–$3,799.00
- Type: Hybrid pillow top
- Height: Approximately 17"
- Comfort rating shown: Plush
- Warranty: 10-year manufacturer warranty

Compare Performance Scores of These Mattresses
| Mattress | Overall Score | Support | Pressure Relief | Cooling | Motion Isolation | Durability | Responsiveness |
| G4 Nova | 4.0 | 4.2 | 4.0 | 4.2 | 4.4 | 4.0 | 3.6 |
| S4 Nebula | 4.2 | 4.3 | 4.1 | 4.5 | 4.1 | 4.3 | 4.2 |
| iQ5 | 4.2 | 4.2 | 4.4 | 4.2 | 4.0 | 4.2 | 4.1 |
| iQ7 | 4.3 | 4.4 | 4.5 | 4.3 | 4.0 | 4.3 | 4.3 |
The S4 Nebula was the most even “cool + supportive” performer. The iQ7 led for pressure relief and edge stability, but carried more movement. The G4 Nova isolated motion best, but it was slower to reset. The iQ5 was the most forgiving on joints while still keeping alignment steady.
How to Choose the iDealBed Mattress?
If you sleep hot or want easier turning, start with the S4 Nebula. If you want the calmest, most motion-damped surface, choose the G4 Nova. For softer, shoulder-friendly comfort that still feels structured, the iQ5 is a strong fit. If you want a thicker pillow-top feel with stronger edges and faster rebound, the iQ7 fits best.
Limitations
The main trade-off is that the more buoyant hybrids (iQ5 and iQ7) carry more motion than the foam-dominant Nova. The Nova is quieter, but slower to respond. The Nebula’s coil feel is more noticeable, so people who want a deep, slow memory-foam “melt” may prefer the all-foam option.
iDealBed Vs. Alternatives
-
Why choose these models
- Cooling-focused covers and gel comfort layers across multiple price tiers
- Clear separation of feels: foam-quiet (Nova) versus hybrid-lift (Nebula and iQ line)
- Reinforced edge builds on the hybrids
-
Alternatives to consider
- Saatva Classic: traditional innerspring bounce and broad firmness options
- DreamCloud Classic Hybrid: value hybrid with a familiar medium feel
- Nectar Classic: all-foam option for deeper contouring
Pro Tips for iDealBed
- Give foam-heavy models a few nights before judging firmness.
- If you sleep hot, pair the Nebula with breathable sheets to support airflow.
- If you sit on the edge daily, you’ll likely prefer the hybrids’ more stable perimeter.
- Rotate the mattress on a schedule that matches your usage pattern.
- If motion bothers you, keep your foundation stable; frame wobble can amplify movement.
FAQs
Which iDealBed model isolates motion the best?
In our partner-movement tests, the G4 Nova felt the calmest and most motion-damped. The hybrids carried more movement because of their spring structure.
Which model felt coolest over a full night?
The S4 Nebula stayed consistently cooler and more breathable in our tests, helped by its cooling cover and airflow-focused hybrid build.
Which is the best choice for side-sleeper pressure relief?
The iQ5 gave us the most reliable shoulder-and-hip comfort without losing support underneath. The iQ7 delivered similarly strong cushioning, but with a more buoyant pillow-top feel and more movement carry.
