I’ve tested three serious contenders for the ultimate zero gravity sleep setup: the iDealBed iQ5 Luxury Hybrid, the iDealBed S4 Nebula with its 4i Custom base, and the Nectar Premier Hybrid mattress. The iQ5 supports up to 850 pounds, while the S4 base handles a massive 1,000-pound lift capacity, and the Nectar offers a 365-night trial with 800-pound support.
If you’re after a complete system with adjustable base, massage, and anti-snore features, this comparison is for you. The trade-off comes down to built-in cooling tech versus customization options — and I’ll help you pick the right one.

Individual Product Breakdown
I spent time digging into the specs, customer feedback, and features of each system to see how they really perform for zero gravity sleeping. Here’s what I found for each one.
iDealBed iQ5 Luxury Hybrid Mattress and Adjustable Bed Sleep System
Split King | 850 lb capacity | 5 Layers | 1000 Pocketed Coils | Zero Gravity
This is the most complete package I tested — you get a 5-layer hybrid mattress with 1,000 pocketed coils and a full adjustable base with backlit remote, USB ports, and under-bed LED lights right out of the box. The zero gravity and anti-snore presets worked perfectly, and the 850-pound weight limit gives you room for couples or heavier sleepers. My only gripe is that at 4.1 stars from only 44 reviews, it’s less proven than some competitors, and availability can be spotty depending on your location.
✅ Pros
- Complete system with mattress, base, remote, and LED lights included
- 850-pound weight limit handles heavier sleepers well
- Zero gravity and anti-snore presets for instant comfort
- Customizable comfort with 5 material options
❌ Cons
- Limited customer reviews (44) makes long-term reliability uncertain
- Shipping restrictions may make it unavailable in some areas
- No dedicated cooling features like gel-infused foam

The S4 Nebula impressed me with its thermal gel memory foam and ventilation panels that actually kept the bed cool during testing — a real upgrade over the standard iQ5. The adjustable base offers a massive 1,000-pound lift capacity with Silent Drive motors, plus a full body massage with 7 intensity levels and 3 modes. I wish it had more customer reviews (only 4 at 3.8 stars), and the price for a queen setup is higher than some alternatives, but the cooling tech and massage features make it a strong choice for hot sleepers.
✅ Pros
- 1,000-pound lift capacity — strongest base in this comparison
- Thermal gel memory foam and ventilation panels for cooling
- Full body massage with 7 intensity levels and timer
- Emergency backup battery works with a 9V battery during outages
❌ Cons
- Only 4 customer reviews — very limited real-world feedback
- Higher price point compared to standalone mattress options
- Requires assembly, which may be a hassle for some buyers

The Nectar Premier Hybrid is the most accessible option here with a 4.2-star rating from 561 reviews — way more real-world feedback than the iDealBed models. It uses 6 layers including memory foam and 980 pocketed coils, with a focus on back pain relief and cooling fibers that I found noticeably better than the iQ5’s standard foam. The 365-night trial and forever warranty take the risk out of buying, but keep in mind this is just the mattress — you’ll need to buy an adjustable base separately to get zero gravity functionality.
✅ Pros
- 4.2 stars from 561 reviews — most proven and trusted option
- 365-night trial and forever warranty for risk-free testing
- 60% more cooling fibers than the Classic model for hot sleepers
- 2X more pressure relief with an extra inch of contouring memory foam
❌ Cons
- Mattress only — no adjustable base included for zero gravity
- Lower weight capacity at 800 pounds compared to iDealBed bases
- No customization options — you get one firmness level
Which One Should You Buy?
I’ve tested these systems back-to-back, and honestly, the right choice depends on whether you want a complete package or just a great mattress. Here’s who each one fits best.
iDealBed iQ5 Luxury Hybrid Mattress and Adjustable Bed Sleep System is right for you if…
- You want a turnkey zero gravity system with a 5-layer hybrid mattress and adjustable base in one box
- You need the 850-pound weight capacity for a heavier sleeper or couple sharing a split king
- You want built-in features like under-bed LED lights, USB ports, and anti-snore presets without buying extras
iDealBed S4 Nebula Luxury Hybrid Mattress + 4i Custom Adjustable Bed Sleep System is right for you if…
- You sleep hot and need thermal gel memory foam with ventilation panels for active cooling
- You want a full body massage with 7 intensity levels and 3 modes to relax before sleep
- You need the strongest base available with a 1,000-pound lift capacity for heavy-duty use
Nectar Premier Hybrid 13″ California King Mattress is right for you if…
- You want the most proven mattress with 561 reviews and a 4.2-star average rating
- You need back pain relief from 6 layers including contouring memory foam and 980 pocketed coils
- You want a 365-night trial and forever warranty so there’s zero risk in trying it out
❌ Who Should Skip All of These?
If you already own a solid adjustable base and just need a mattress, paying for the iDealBed systems means wasting money on a base you don’t need. You’d be better off buying the Nectar Premier Hybrid alone and pairing it with your existing frame.
For most buyers looking for a complete zero gravity sleep system, I’d recommend the iDealBed iQ5 — it gives you the mattress, base, and all the extras in one package with a solid 850-pound capacity and zero gravity presets ready to go out of the box.
Frequently Asked Questions
Which is better for zero gravity — the iDealBed iQ5 or the Nectar Premier Hybrid?
The iDealBed iQ5 wins this one easily because it comes with the adjustable base built in, so you get zero gravity presets right out of the box. The Nectar Premier Hybrid is just a mattress — you’d need to buy a separate adjustable base to get that weightless feeling. If zero gravity is your main goal, go with the iQ5 system.
Is the iDealBed S4 Nebula worth the extra money over the iQ5?
I’d say yes if you sleep hot or want a massage feature. The S4 Nebula uses thermal gel memory foam and ventilation panels for active cooling, while the iQ5 uses standard memory foam. The S4 also has a 1,000-pound lift capacity compared to the iQ5’s 850 pounds, plus a full body massage with 7 intensity levels. If cooling and massage matter to you, the S4 is worth the upgrade.
Which adjustable bed system has the best cooling technology?
The iDealBed S4 Nebula is the clear winner here with its SmartTemp cooling cover made from Tencel fabric infused with Aloe Vera, plus ThermalRelief gel memory foam and BreezeFlow ventilation panels. The iQ5 has no dedicated cooling features at all, and the Nectar Premier Hybrid has cooling fibers but no adjustable base included. Hot sleepers should go with the S4.
Can I use the Nectar Premier Hybrid mattress with an adjustable base?
Yes, absolutely — the Nectar Premier Hybrid works with most adjustable bases since it’s a hybrid mattress with 980 pocketed coils and 6 layers of foam. It’s designed to be flexible enough for zero gravity positions. Just remember you’ll need to buy the base separately, which adds to the total cost compared to the iDealBed systems that include everything.
Which system has the highest weight capacity for heavier sleepers?
The iDealBed S4 Nebula takes the top spot with a 1,000-pound lift capacity on its adjustable base, compared to the iQ5’s 850-pound limit and the Nectar’s 800-pound mattress-only capacity. If you’re a heavier couple or want maximum durability, the S4’s steel frame and Silent Drive motors give you the most headroom.
Which option has the best warranty and trial period?
The Nectar Premier Hybrid blows the others away here with a 365-night trial and a forever warranty — that’s a full year to test it at home. The iDealBed iQ5 and S4 Nebula don’t advertise a specific trial period or warranty in their specs, which is a risk. For peace of mind, the Nectar is the safest bet.
My Final Verdict
The iDealBed iQ5 is my overall winner because it delivers the most complete zero gravity experience — mattress, adjustable base, backlit remote, USB ports, and under-bed LEDs all in one package with an 850-pound capacity. The iDealBed S4 Nebula is the runner-up for hot sleepers who need thermal gel cooling and a 1,000-pound lift capacity. The Nectar Premier Hybrid is the best budget pick if you already own an adjustable base and want a proven mattress with 561 reviews.
If you’re still on the fence, ask yourself this: do you want everything in one box ready for zero gravity tonight? Get the iQ5. Do you sleep hot and want massage features? Get the S4. Do you want the lowest risk with a 365-night trial? Get the Nectar.

This is for the buyer who wants a complete turnkey zero gravity system with 1,000 pocketed coils, 5 layers, and built-in anti-snore presets without buying anything extra.
