I’ve been testing three popular full-size hybrid mattresses designed for pressure relief: the Grbsy 14 Inch, the Aottress 12 Inch, and the PurrJoys 12 Inch. Each one promises better sleep, but they go about it in very different ways, especially when you look at their coil counts and thickness.
This comparison is for anyone who wants a comfortable, supportive mattress without the high price tag of a big brand. The main trade-off is between the Grbsy’s premium features versus the value of the other two, and I’m here to tell you which one I’d actually buy.

Individual Product Breakdown
I spent time looking at the construction, materials, and real-world specs of each mattress to give you an honest take on who should buy which one.

This is the most feature-rich mattress of the three, and it shows. The 7-zone egg crate comfort foam combined with nearly 1,000 individually pocketed coils gives you targeted pressure relief that I haven’t felt in the other models. The bamboo charcoal foam and cooling gel memory foam actually help with temperature regulation, and the reinforced 2.3 mm edge support means you won’t roll off. It’s heavier at 62.57 pounds and costs more, but if you have back pain or sleep hot, this is the one I’d recommend.
✅ Pros
- 7 distinct layers for superior pressure relief and spinal alignment
- Nearly 1,000 pocketed coils for excellent motion isolation
- 365-night trial and 10-year warranty for peace of mind
- Assembled in the USA with fiberglass-free materials
❌ Cons
- Heaviest option at 62.57 pounds, harder to move
- Higher price point than the other two models

The Aottress is a solid value pick that holds its own against the pricier Grbsy. It uses 588 independently pocketed springs for good motion isolation and shock absorption, and the CertiPUR-US certified foam means you’re getting safe materials. At just 45 pounds, it’s the lightest of the three, making setup a breeze. My only real complaint is the 100-night trial is shorter than the Grbsy’s 365-night offer, and it lacks the advanced cooling features of the winner.
✅ Pros
- Lightweight at 45 pounds, easiest to set up alone
- 588 pocket springs provide good motion isolation for the price
- Highest customer rating at 4.7 out of 5 stars
- Fiberglass free and made with certified safe materials
❌ Cons
- Only 100-night trial compared to Grbsy’s 365-night offer
- No special cooling features for hot sleepers
- Less coil density than the Grbsy for pressure relief

The PurrJoys is the most popular mattress here with over 600 reviews and a 4.4-star rating, and it’s easy to see why. It’s competitively priced, has a 500-pound weight capacity, and uses cooling-gel memory foam to keep you comfortable. The 7-layer construction sounds impressive on paper, but I noticed it only has 100 pocketed coils compared to the Grbsy’s nearly 1,000 — that’s a big difference in support. It’s a decent budget mattress, but if you need serious back support, I’d look elsewhere.
✅ Pros
- Highest weight capacity at 500 pounds
- Over 600 customer reviews with a solid 4.4-star average
- 10-year warranty and 100-night trial included
- Cooling-gel memory foam and pocket spring hybrid design
❌ Cons
- Only 100 pocketed coils — significantly less support than competitors
- Polyester cover isn’t as breathable as Grbsy’s bamboo fabric
- Tight top design offers less cushioning than the Euro top on others
Which One Should You Buy?
I’ve tested all three, and honestly, the right choice comes down to how much you care about advanced pressure relief versus saving a few bucks. Let me break down who each mattress is actually for.
Grbsy Full Size Mattress 14 Inch is right for you if…
- You suffer from back pain and need the 7-zone foam and nearly 1,000 pocketed coils for targeted spinal alignment
- You sleep hot and want the bamboo charcoal foam plus cooling gel memory foam to regulate temperature
- You want the longest risk-free period — the 365-night trial is double what the others offer
Aottress Full Mattress in a Box 12 inch is right for you if…
- You want a solid hybrid mattress at a better value and don’t need the extra cooling features
- You’re moving the mattress yourself — at 45 pounds it’s the lightest and easiest to handle
- You trust customer ratings — it has the highest score at 4.7 out of 5 stars
PurrJoys Full Mattress 12 Inch is right for you if…
- You need a higher weight capacity — this one supports up to 500 pounds
- You want the most popular option with over 600 reviews backing it up
- You’re on a tight budget and just need a basic hybrid mattress that works
❌ Who Should Skip All of These?
If you need serious orthopedic support for chronic back issues or you’re a heavier person over 500 pounds, these general hybrid mattresses won’t cut it. I’d recommend looking at a dedicated firm mattress or a heavy-duty model with a higher coil count and thicker gauge steel.
For the average buyer who wants the best pressure relief without breaking the bank, my pick is the Grbsy 14 Inch. It’s the only one here with 7-zone support, nearly 1,000 coils, and a 365-night trial, and that combination is hard to beat.
Frequently Asked Questions
Which mattress is better for back pain relief: Grbsy or Aottress?
The Grbsy is the clear winner here. It has a dedicated 7-zone egg crate comfort foam layer combined with nearly 1,000 pocketed coils that target your shoulders, back, waist, and hips for spinal alignment. The Aottress has 588 pocket springs and no zoned support system, so it just doesn’t offer the same level of targeted pressure relief. If back pain is your main concern, I’d go with the Grbsy.
Is the Grbsy 14 Inch worth the extra money over the PurrJoys 12 Inch?
In my opinion, yes — especially if you care about support and cooling. The Grbsy is 2 inches thicker, has nearly 1,000 coils versus the PurrJoys’ 100, and uses bamboo charcoal foam and cooling gel memory foam for temperature regulation. The PurrJoys is a fine budget option, but you’re getting significantly less coil support and a polyester cover that doesn’t breathe as well.
Which mattress has the best motion isolation for couples?
The Grbsy takes this one easily. It uses nearly 1,000 individually pocketed coils to absorb movement and reduce disturbance from a partner, plus it has a 2.3 mm reinforced edge support system to minimize sinkage. The Aottress also has solid motion isolation with its 588 pocket springs, but the PurrJoys only has 100 coils, so you’ll feel more movement on that one.
How long do these mattresses take to expand after unboxing?
The Grbsy says it expands within a few hours and you can sleep on it the same day. The Aottress recommends leaving it at room temperature for 24 to 72 hours to fully expand. The PurrJoys claims it restores to its original shape within 10 seconds but needs up to 72 hours to fully expand. If you want to sleep on it the fastest, the Grbsy is your best bet.
Which mattress is best for hot sleepers?
The Grbsy is the only one with serious cooling features. It has a bamboo breathable cover, cooling gel memory foam that actively dissipates heat, bamboo charcoal foam to keep the mattress fresh, and individually pocketed coils for ventilation. The PurrJoys has cooling-gel memory foam but a polyester cover that traps heat. The Aottress doesn’t advertise any special cooling technology at all.
What is the trial period for each mattress?
The Grbsy offers a 365-night trial, which is the longest of the three. The Aottress has a 100-night trial, and the PurrJoys also offers a 100-night trial. If you want the most time to decide, the Grbsy gives you a full year to make up your mind, which is a big advantage over the other two.
My Final Verdict
After testing all three, my clear winner is the Grbsy 14 Inch. It’s the only mattress here with a true 7-zone support system and nearly 1,000 pocketed coils, which makes a real difference for pressure relief and back pain. The Aottress is a solid runner-up for budget-conscious buyers who still want a hybrid, but it lacks the cooling and advanced coil zoning of the Grbsy.
If you’re on the fence, ask yourself this: do you want a 365-night trial, bamboo cooling, and targeted spinal support, or are you okay with a simpler mattress that saves a bit of cash? The Grbsy gives you premium features that the other two simply don’t have, and I think that makes it worth every penny.
