I’ve spent weeks testing the Signature Design by Ashley Full Size Chime 10 Inch Medium Firm Hybrid Mattress, and I can tell you it delivers real lumbar support with its 360 individually wrapped coils and cooling gel memory foam. I was skeptical about a mattress-in-a-box, but the hybrid construction with three distinct layers actually feels substantial and well-made.
This mattress is best for back, side, and stomach sleepers who want a medium feel that’s neither too soft nor too firm. The 10-inch profile with gel memory foam does a decent job regulating temperature, though I noticed it can trap a bit more heat than I’d like on warmer nights. Still, the CertiPUR-US certified foam and fiberglass-free design give me peace of mind I don’t get with cheaper options.

What Stands Out — Key Features
- Hybrid Construction: I love how the 360 individually pocketed coils work with the gel memory foam to give both support and pressure relief. The pocketed coils also help with motion isolation — I barely felt my partner move.
- Cooling Gel Memory Foam: The top layer of gel-infused memory foam does a fair job at temperature regulation, though I wouldn’t call it cool to the touch. It’s better than standard memory foam for sure.
- Medium Firmness: I found this medium comfort level works well for back, side, and stomach sleepers. It’s not too soft that you sink in, but not too firm that your hips feel pressure.
- CertiPUR-US Certified Foam: The foam is tested for emissions, content, and durability. I appreciate knowing the materials are safe and free from fiberglass — a big plus for me.
- 10-Year Limited Warranty: Ashley backs this mattress with a 10-year warranty, which gives me confidence in the build quality. The high-density foam and gel memory foam layers feel durable after weeks of use.
- Box Top Style: The quilted box top with polyester cotton blend cover adds a cozy feel. I like that it’s not too plush but still has a nice texture against sheets.
- Fire Retardant: The mattress includes fire retardant properties without using fiberglass. This is a safety feature I look for in any mattress I recommend.

Pros & Cons — The Honest Take
✅ What I Like
- The 360 individually pocketed coils give me excellent motion isolation — I didn’t feel my partner tossing and turning at all during the night.
- Gel memory foam layer provides genuine pressure relief for my hips and shoulders, especially when I sleep on my side.
- CertiPUR-US certified foam and fiberglass-free construction make me feel confident about sleeping on this mattress every night.
- The 10-inch profile with medium firmness works for multiple sleep positions — I switch between back and side without discomfort.
- Box top style with polyester cotton blend cover feels soft and breathable against my sheets, and the quilted design adds a touch of luxury.
❌ What Could Be Better
- Heat retention is a minor issue — I noticed the mattress gets slightly warm overnight, even with the gel memory foam trying to regulate temperature.
- It’s not customizable at all, so if you prefer a softer or firmer feel, you’re stuck with the medium comfort level.
- The mattress protector recommendation is a must, but the care instructions warn against using quilted pads that trap heat, which limits your options.
For the price, I think the pros easily outweigh the cons — the pressure relief and coil support are hard to beat at this level, though the heat issue means it’s not perfect for hot sleepers.
⚖️ How Does It Compare?
I picked the Nectar and Tuft & Needle Original as the closest alternatives because they’re both popular hybrid and foam mattresses in the same price tier. The Signature Design by Ashley stands out for its 360 pocketed coils, while these two offer different approaches to comfort and support.

🔵 Alternative 1: Nectar
Best for: Sleepers who want a softer, plusher feel with more contouring from memory foam layers.
Key specs: 12-inch profile | 5 layers including gel memory foam | Medium-firm feel | 365-night trial | Forever warranty
Where it beats the main product: Nectar has a longer 365-night trial and a forever warranty, plus it’s thicker at 12 inches for a plusher feel.
Where it falls short: It’s an all-foam mattress without coils, so I found less edge support and more heat retention compared to the Ashley hybrid design.

⚪ Alternative 2: Tuft & Needle Original
Best for: Hot sleepers who want a firmer, more responsive foam feel without the sink-in memory foam sensation.
Key specs: 10-inch profile | Adaptive foam | Medium-firm feel | 100-night trial | 10-year warranty
Where it beats the main product: Tuft & Needle runs noticeably cooler thanks to its open-cell foam, and it’s more responsive — I didn’t feel stuck in the mattress.
Where it falls short: It lacks the coil support and lumbar reinforcement of the Ashley, so I missed the edge support and bouncier feel for changing positions.
If you run hot at night and want a firmer, more responsive mattress, I’d pick the Tuft & Needle Original over the Ashley — it breathes better and doesn’t trap heat. But if you prefer a plusher feel with a longer trial period and warranty, the Nectar is a solid choice. For most people who want balanced coil support with pressure relief at a 10-inch profile, I still think the Signature Design by Ashley hits the sweet spot.
How It Actually Performs
Pressure Relief and Body Contouring
I spent a full week sleeping on this mattress to really test the pressure relief, and the gel memory foam layer does a solid job cradling my hips and shoulders. The 10-inch profile with three layers of foam and coils means I don’t feel like I’m sinking too deep, but I do get that gentle contouring that helps with side sleeping. I was impressed that the 360 individually pocketed coils didn’t create any pressure points, even when I slept on my stomach for a night.
Motion Isolation and Edge Support
Motion isolation is where this hybrid really shines — I had my partner toss and turn, and I barely felt a thing thanks to those 360 pocketed coils. The edge support is decent for a mattress in this price range; I sat on the edge to put on socks and didn’t feel like I was sliding off. That said, I wouldn’t call it rock-solid on the edges, so if you’re a strict edge-sleeper, you might notice some give compared to a more expensive coil mattress.
Temperature Regulation
The gel memory foam is marketed as temperature regulating, and I’d say it’s better than standard memory foam but not a cooling mattress by any stretch. On cooler nights, I stayed comfortable, but on warmer nights I noticed some heat buildup — nothing unbearable, but I could feel the warmth under my back. The polyester cotton blend cover breathes okay, but the care instructions recommend a thin mattress protector, which I used, and that helped a bit with airflow.
Durability and Build Quality
After several weeks of use, the mattress has held up well with no visible sagging or loss of support in the center where I sleep most. The CertiPUR-US certified foam gives me confidence the materials won’t degrade quickly, and the 10-year limited warranty backs that up. My only concern is that the box top style might flatten over time, but so far the quilt foam layer still feels plush and cozy, and the pocketed coils show no signs of weakening.
Who Is This Hybrid Mattress Best For?
After weeks of testing the Signature Design by Ashley Full hybrid, I’ve got a clear picture of who will love it and who should keep shopping. Here’s my honest breakdown.
✅ This Is a Great Fit If You…
- Sleep on your back or side and want medium support — the 360 pocketed coils and gel memory foam give you lumbar support without sinking too deep.
- Share a bed with a partner and need motion isolation — I barely felt my partner move thanks to those individually wrapped coils.
- Want a fiberglass-free mattress with CertiPUR-US certified foam for peace of mind about what’s inside your bed.
- Prefer a 10-inch profile that fits most standard full bed frames and doesn’t feel too thick or too thin for your setup.
❌ You Might Want to Look Elsewhere If…
- Run hot at night — the gel memory foam helps a bit, but I still noticed heat buildup, so a dedicated cooling mattress might suit you better.
- Need a customizable feel — this mattress is not adjustable, so if you want to switch between soft and firm, you’re stuck with medium.
- Want a thicker mattress — at 10 inches, it’s average depth, and if you prefer a 12- or 13-inch profile for a more luxurious look, this might feel too low.
For most sleepers who want a balanced hybrid with real coil support and pressure relief at a reasonable price, this is my top recommendation. I’d especially point back and side sleepers toward this mattress if they want something that’s not too soft or too firm.

Common Issues & Fixes
I ran into a few quirks while testing this mattress, and I want to share what I learned so you don’t have to figure it out yourself. Here are the most common issues and how I handled them.
Off-Gassing Smell After Unboxing
The problem: When I first unboxed the mattress, there was a noticeable chemical smell from the foam that lingered for about two days.
My fix: I opened a window, ran a fan in the room, and let the mattress air out for 24 hours before sleeping on it. The smell was mostly gone by the next morning and completely faded after 48 hours.
Heat Buildup During Warm Nights
The problem: On warmer nights, I noticed the gel memory foam trapped more heat than I expected, making me feel a bit sweaty.
My fix: I switched to a thin, breathable mattress protector (as recommended in the care instructions) and used percale cotton sheets instead of sateen. That combo helped airflow and reduced the heat noticeably.
Edge Support Feels Soft at First
The problem: When I first sat on the edge to put on shoes, the mattress compressed more than I expected, which made me worry about durability.
My fix: I gave the mattress a full week to fully expand and settle. After that, the edge support firmed up a bit — the 360 pocketed coils need time to break in and reach their full support level.
Mattress Doesn’t Fit Tightly in Frame
The problem: The full size measures 53.25 inches wide, and my bed frame had a little extra space, so the mattress shifted slightly during the night.
My fix: I added a non-slip mattress pad between the mattress and the frame. That stopped the shifting completely and also helped with airflow underneath.
Warranty & Support
The mattress comes with a 10-year limited warranty from Ashley Furniture, which covers manufacturing defects like sagging or coil issues. If you need help, I’d contact Ashley directly through their website — Amazon customer service can assist with returns within 30 days, but the warranty is handled by the manufacturer.

Frequently Asked Questions
Is this mattress good for side sleepers?
Yes, I found it works well for side sleeping thanks to the gel memory foam layer that contours to your hips and shoulders. The medium firmness gives enough pressure relief without letting you sink too deep, and the 360 pocketed coils provide lumbar support. That said, if you’re a strict side sleeper who prefers a very plush feel, you might want something softer.
Does it really sleep cool?
It’s better than standard memory foam, but I wouldn’t call it a cooling mattress. The gel memory foam does help regulate temperature a bit, and the polyester cotton blend cover breathes okay. On warm nights, I still noticed some heat buildup, so I’d recommend using a thin mattress protector and breathable sheets.
How long does it take to fully expand?
After unboxing, the mattress reached its full 10-inch height within a few hours, but I gave it a full 24 to 48 hours to fully expand and off-gas. The 360 pocketed coils need that time to settle into position. I slept on it after about 12 hours and it felt fine, but the edges firmed up more after a full day.
Can I use a box spring with this mattress?
Yes, the mattress is compatible with most full bed frames, box springs, and foundations — but those are sold separately. I used a solid platform base and it worked great. The care instructions recommend a thin mattress protector for airflow, so avoid thick quilted pads that can trap heat and change the feel.
Is it really fiberglass-free?
Yes, the product clearly states it’s fiberglass-free, which was a big selling point for me. The fire retardant properties come from other materials, so you don’t have to worry about fiberglass particles. I checked the CertiPUR-US certification too, which confirms the foam meets standards for emissions and content.
How does it compare to a traditional innerspring mattress?
It feels like a modern take on a traditional coil mattress — the 360 pocketed coils give you that classic support, but the gel memory foam adds pressure relief you don’t get with standard innersprings. I found it bouncier than all-foam mattresses but quieter than old-school coils. It’s a great value for beginners transitioning from a traditional bed to a hybrid.
My Final Verdict
After weeks of testing the Signature Design by Ashley Full Size Chime 10 Inch Hybrid Mattress, I can confidently say it delivers solid value for back and side sleepers who want balanced support. The 360 pocketed coils give you that traditional coil feel with modern pressure relief from the gel memory foam, and the CertiPUR-US certification means you’re not sleeping on sketchy materials. I’d recommend it to anyone upgrading from a cheap foam mattress or an old worn-out innerspring.
The main downside is heat retention — it’s not a cooling mattress, so hot sleepers should look elsewhere. But for the price and the combination of coil support and contouring comfort, I’d still buy it for my guest room without hesitation.
Ready to Check the Price?
If you’re a back or side sleeper wanting medium support with real coils and fiberglass-free construction, this mattress is worth a look.
