Comfort IQ™ · Scored on what actually matters
SPRINGWALL® Chiropractic® 11″ Plush Tight-Top Mattress — Performance & Feel
Comfort IQ™ scores eight dimensions 0–10 from National Mattress's in-house testing + construction — the same scale on every model, so two beds compare on what actually matters. Results vary by body type, base, and room temperature.
The SPRINGWALL Chiropractic 11″ Plush scores a perfect 10/10 for cooling — peaking near 29°C, one of the coolest results in our entire field. Running this cool on a bed branded plush is a real engineering win, built on 1,800 pocketed coils (the most in this lineup) with a micro-coil layer and a Cold PE Technology cover. The honest surprise: despite the plush name, its measured feel lands at a balanced medium 4/10, so it rests more supportive-on-top than deep-sinking. True deep-cradle seekers should know it sleeps firmer than its name suggests.
Performance Scores
A high-coil-count plush hybrid that leads the field on cooling, with strong responsiveness and motion control. Its most modest axis is edge support — still solid, just its lowest performance number.
Cooling10.0
Peaks near 29°C — one of the coolest beds in the field.
Responsiveness9.4
1,800 coils give it real life — resets quickly and moves easily.
Motion Isolation9.0
The most contact points in the lineup localize a partner's movement.
Spinal Support8.6
Zoned lumbar band over a heavy coil count keeps the spine level.
Durability8.3
A thin firm comfort layer over heavy coils — strong long-term support.
Pressure Relief7.7
A medium feel with even contour — supportive rather than deep-cradling.
Edge Support7.6
Dense pocketed coils hold the perimeter — no sudden roll-off.

Best For
Hot sleepers cooling tops out at 10/10, peaking near 29°C — one of the coolest beds we test, and rare on a plush model.
Combination sleepers responsiveness scores 9.4/10 on 1,800 coils, so moving around is easy and the surface never traps you.
Couples motion isolation scores 9.0/10 — with the most contact points in the lineup, a restless partner won't jostle you awake.
Back sleepers who want a softer surface spinal support scores 8.6/10 with a zoned lumbar band and chiropractic-college endorsement.
Buyers who want cooling and support in one bed a true premium hybrid with the highest coil count in the lineup.
Considerations
Firmer than its plush name suggests the measured feel is a medium 4/10 with sinkage in the 1.79-2.81 inch range — supportive-on-top, not a deep sink. True deep-cradle seekers should set expectations.
Edge support is its softest performance axis (7.6/10) still genuinely solid and roll-off-free, just the lowest number on an otherwise high-scoring bed.
How It Performs — The Measured Detail
Feel & Firmness · 4/10 Plush
Despite the plush branding, the Springwall Chiropractic 11″ Plush measures at a balanced medium 4/10 — it rests more supportive-on-top than enveloping. An inch of conforming gel foam softens the shoulders and hips, but with 1,800 pocketed coils and a micro-coil layer doing the work under only a thin comfort layer, you ride on the springs rather than sinking into foam. The result is a lively, easy-to-reposition feel.
Cooling 10.0
Cooling is the strongest trait of the Springwall Chiropractic 11″ Plush: peak surface temperature stays in the 28.9-31.7 °C range, near the floor of it, and the rise over baseline holds to the 6.9-9.7 °C range — one of the coolest results in the entire field. Three things stack to get there: an inch of gel-infused foam draws heat off the surface, a breathable tempered-steel micro-coil layer sits just below to keep air moving, and the Cold PE Technology cover pulls warmth out of the comfort layer itself. For a bed branded plush — usually more hugging foam and more trapped heat — running this cool is a real engineering win.
Pressure Relief 7.7
Measured firmness lands at a medium 4/10, putting the Springwall Chiropractic 11″ Plush in a balanced sweet spot. Sinkage settles in the 1.79-2.81 inch range, at the shallow end, so the feel is more supportive-on-top than deep-cradle despite the plush branding. An inch of conforming gel foam softens the shoulders and hips while the zoned coils flex under the heaviest points. It is a comfortable middle ground for back sleepers and lighter side sleepers; those wanting a true deep-sinking hug should know this one rests firmer than its name suggests.
Motion Isolation 9.0
Movement stays well managed across the Springwall Chiropractic 11″ Plush, with peak transferred motion in the 2.90-6.20 m/s² range and a settle time of 0.95-1.16 seconds. A double spring system does it: 1,800 pocketed coils that each move on their own, plus a micro-coil layer above for a second tier of fine isolation. With 1,800 coils, this bed has more independent contact points than most, which helps localize a partner's motion — good isolation for a responsive hybrid, so a restless sleeper next to you will not jostle you awake.
Edge Support 7.6
The perimeter holds firm on the Springwall Chiropractic 11″ Plush: edge sinkage measures in the 2.65-4.71 inch range, toward the strong end of the field, so the edge stays supportive whether you are perched on the side or sleeping near the rim. The dense pocketed-coil structure means no sudden roll-off and full use of the mattress corner to corner. For a couple who spreads out, or anyone who sits on the bed to get dressed, that dependable edge is a genuine plus.
Responsiveness 9.4
The Springwall Chiropractic 11″ Plush has plenty of life to it. Bounce total travel reaches the 7.92-12.65 inch range, near the top of that band, and the surface springs back in under 2.53 seconds to full and under 1.26 seconds to mostly settled — it resets quickly and makes moving around easy. With 1,800 pocketed coils and a micro-coil layer doing the work and only a thin gel comfort layer on top, you ride on the springs rather than sinking into foam. It is a lively, easy-to-reposition feel that suits combination sleepers.
Off-Gassing 9.0
Off-gassing is minimal on the Springwall Chiropractic 11″ Plush — any odor clears in under 12 hours, well short of the typical mattress. The foams are CertiPUR-US certified, independently tested for low VOCs, and the bed is built in Ontario and delivered flat instead of tightly compressed, so there is less trapped-foam smell to release than a boxed bed. A couple of days of fresh air in the room after unpackaging and any faint smell is gone. It is fiberglass-free as well.
Sleep Position & Body Weight Fit
The medium 4/10 feel makes the Springwall Chiropractic 11″ Plush a flexible fit for back sleepers and lighter-to-average side sleepers, who get even support with a touch of cushion. Combination sleepers benefit from the springy, easy-to-move surface. Heavier sleepers get strong, even support from the 1,800-coil base. The one mismatch is the dedicated deep-cradle seeker — this bed sits firmer than its plush name implies, so anyone after a true sink should weigh that.

Frequently Asked
Does the Springwall Chiropractic 11″ Plush sleep hot?
No — it scores a perfect 10/10 for cooling, one of the coolest results in our entire field. Peak surface temperature stays near 29°C, helped by gel-infused foam, a breathable micro-coil layer, and a Cold PE Technology cover. Running this cool on a plush bed is rare.
Is the Springwall Chiropractic 11″ Plush actually plush?
It is softer than the firm model but rests firmer than its name suggests. The measured feel is a balanced medium 4/10 with sinkage in the 1.79-2.81 inch range — supportive-on-top rather than a deep sink. If you want a true deep cradle, set expectations accordingly.
Is the Springwall Chiropractic 11″ Plush good for couples?
Yes. It scores 9.0/10 for motion isolation. With 1,800 individually pocketed coils — the most in this lineup — plus a micro-coil layer, it has more independent contact points than most beds, which localizes a partner's movement so it won't jostle you awake.
Can I try the Springwall Chiropractic 11″ Plush at home?
Yes. It comes with a 365-night sleep trial, so you have a full year to be sure through every season before committing. If it ends up not being right after testing it, send it back for a refund or arrange an exchange. Delivery is free on orders over $199.
How many coils does the Springwall Chiropractic 11″ Plush have?
It has 1,800 individually pocketed tempered-steel coils — the highest coil count in this lineup — plus an added micro-coil layer. That dense coil base drives its strong motion isolation, responsiveness, and chiropractic-college-endorsed spinal support.
