Comfort IQ™ · Scored on what actually matters
SPRINGWALL® Luxury Chiropractic® 16″ Ultra Plush Pillow 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 Luxury Chiropractic 16″ Ultra Plush Pillow Top is a genuine deep-cradle plush bed, scoring 8.3 for pressure relief at a soft 2/10 firmness. The shoulders and hips settle into a gentle 1.96-2.97 inch contour, yet a copper phase-change cover keeps it cool and a deep pocketed-coil core holds the spine supported under all that cushioning. Built for lighter side sleepers; the one honest note is that a deep-plush bed runs a little softer at the rail than a firm model would.

Best For
Lighter side sleepers — an 8.3 pressure relief at a soft 2/10 lets the shoulder and hip sink into a gentle cradle, exactly what side sleeping needs.
Plush-bed lovers who run hot — a perfect 10.0 cooling holds the surface to 30.5°C even with a thick pillow top, where soft beds usually sleep warm.
Couples — a 9.0 motion isolation, with the deep plush top soaking up movement, means a restless partner barely reaches your side.
Soft-bed shoppers who still want support — an 8.3 spinal support shows the strong coil core keeps the spine level even under a very soft surface.
Considerations
Softer at the rail (Edge Support 7.2) — edge sinkage runs 3.11-5.18 inches; that is solid for a deep-plush build but a soft bed trades some edge firmness for its cushioned surface, so it runs softer at the side than a firm model.
A plush flagship (Value 3.9) — the deep pocketed-coil system, micro-coil tier, copper cooling cover and ultra-plush top are genuinely upscale materials rather than the most raw material per dollar.
Best for lighter bodies — at a soft 2/10, heavier back and stomach sleepers may sink past the support layer; this bed is matched to lighter side sleepers who want the surface to give.
How It Performs — The Measured Detail
Feel & Firmness · 2/10 Plush
A genuinely soft 2/10: the thick pillow top and comfort layers let you settle into a deep, enveloping surface. Beneath the cushion sits a serious coil system, so the plush comes from the top layers, not from a weak core. The feel is sink-in and cradling, with enough coil life underneath to keep it from feeling like a sinkhole.
Cooling 10.0
A thick, plush pillow top is exactly where beds tend to sleep hot — this one does not. Peak surface temperature lands in the 28.8-31.6°C range and the rise over baseline stays in the 6.8-9.6°C range, both cooler than the typical mattress and impressive given the deep comfort layers. A copper phase-change cover sits on top, a micro-coil tier of tempered steel beneath it keeps air circulating where a pillow top usually traps heat, and the deep pocketed-coil core vents warmth through the body of the bed. The settled temperature finishes in the 22.9-27.0°C range. You sink in deep and still stay cool.
Pressure Relief 8.3
This is the bed's reason for being. At a firmness of 2 out of 10 it is genuinely plush, a deep pressure-relieving cradle, and sinkage measures in the 1.96-2.97 inch range — letting the shoulders and hips settle into a gentle contour rather than resting on top. The comfort layer plus the pillow top wrap around your pressure points while the zoned pocketed coils flex underneath to keep things supported. Lighter side sleepers, who need the shoulder and hip to sink in, will feel the relief immediately.
Motion Isolation 9.0
For a couple, this plush bed is remarkably still. Peak motion acceleration falls in the 2.81-6.10 m/s² range — among the lower readings we record — and the disturbance settles within the 0.94-1.15 second range, both better than the typical mattress. Three things soak up movement: the deep pillow-top foam, a micro-coil tier, and the pocketed coils below, each acting on its own. The soft surface absorbs motion rather than transmitting it, so a partner shifting or getting up barely reaches your side.
Edge Support 7.2
The perimeter here is supportive but, fittingly, on the softer side. Edge sinkage measures in the 3.11-5.18 inch range while lying near the side — solid for such a plush, deep pillow-top build, where edges usually give way more readily. The pocketed-coil system still carries support to the side, so you can sit on the edge or sleep near it without feeling you will slide off. Just know a deep-plush bed trades some edge firmness for its cushioned surface; this one holds up better than most in its softness class.
Responsiveness 8.5
Even with its deep plush feel, this bed is not a sinkhole to move on. Total bounce travel lands in the 8.34-13.07 inch range, toward the upper end of what we measure — the pocketed coils and micro-coil tier beneath the cushioning still spring back, and quickly, with the surface mostly recovering in under 1.30 seconds. A soft, sink-in top will never feel as athletic as a firm one, but beneath the plush there is a genuinely lively coil system keeping the bed from feeling stuck when you reposition.
Off-Gassing 9.0
Despite its generous foam content, this bed has almost nothing to air out. Initial odor rates Low and clears in under 12 hours because it is built in Ontario and delivered flat in a plastic bag rather than vacuum-compressed in transit, which is what traps the concentrated smell — even with a thick comfort layer. The foams are CertiPUR-US certified, independently tested against strict low-emission limits. Airing the room briefly is all it takes.
Sleep Position & Body Weight Fit
This is a lighter side sleeper's bed first and foremost: the soft 2/10 surface and deep cradle let the shoulder and hip sink in for relief while the strong coil core keeps the spine neutral. Average side sleepers who like a plush feel are well matched too. Heavier sleepers and dedicated back or stomach sleepers may sink past the support layer and will likely prefer a firmer model.

Frequently Asked
Is the Springwall Luxury Chiropractic 16″ Ultra Plush good for side sleepers?
Yes, especially lighter ones. It scores 8.3 for pressure relief at a soft 2/10, with 1.96-2.97 inch sinkage that lets the shoulder and hip settle into a gentle cradle — exactly the relief side sleeping needs.
Does the Luxury Chiropractic 16″ Ultra Plush sleep hot?
No. It earns a perfect 10.0 cooling score, holding the surface to 30.5°C in our in-house testing even though a thick pillow top is where plush beds usually trap heat. A copper phase-change cover and a tempered-steel micro-coil tier keep air moving.
Is a plush bed like the 16″ Ultra Plush still supportive?
Yes. It scores 8.3 for spinal support. The plush comes from the surface layers, while a high-count pocketed-coil core with a zoned lumbar band underneath keeps the spine level — the softness is on top, the support is built in.
Can I try the Luxury Chiropractic 16″ Ultra Plush at home?
Yes. It comes with a 365-night sleep trial, which a plush bed especially rewards — a soft, deep-cradle surface can take weeks to settle into. Delivery is free on orders over $199, and you can return it for a refund or exchange if it is not right.
Where is the Springwall Luxury Chiropractic 16″ Ultra Plush made?
It is made in Canada by Springwall, a maker building mattresses since 1929. Because it is built in Ontario and delivered flat rather than compressed for months in transit, off-gassing is minimal — odor clears in under 12 hours.
