Comfort IQ™ · Scored on what actually matters
BEAUTYREST® World Class™ 16″ Pillow Top Medium-Firm 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 BEAUTYREST World Class 16″ Pillow Top isolates motion better than anything in its group, scoring 8.9. Peak transfer came in right at the floor of its range — about 2.7 m/s² — so a partner climbing in or turning over barely registers across the bed. At a balanced medium 5-out-of-10 feel it pairs that calm with a top cooling result and class-leading pressure relief, the alignment sweet spot for the widest range of sleepers. The deep memory layer cradles the shoulders and hips while the 1000-coil core keeps the spine level, so couples and combination sleepers get both a quiet bed and a luxurious settle-in feel. If you want an undisturbed night next to a restless partner with a plush, pillow-top embrace, this is the standout.

In National Mattress's in-house Comfort IQ analysis, the World Class 16″ Medium-Firm scores: Overall 9.1/10, Cooling 9.4/10, Pressure Relief 9.6/10, Motion Isolation 8.9/10, Edge Support 9.3/10, Responsiveness 7.9/10, Spinal Support 9.2/10, Durability 8.7/10.
Best For
Couples and light sleepers — motion isolation scores 8.9, the best in its group, so a restless partner's movement barely crosses the bed.
Side and combination sleepers — pressure relief scores 9.6 and the medium feel cradles the shoulders and hips while still holding you on top.
Hot sleepers who want a plush feel — cooling scores 9.4, so this deep 16″ build sheds heat rather than banking it.
Shoppers who want the feel to last — durability scores 8.7, with genuine high-density foam over 1000 heavy-gauge coils built to hold up over the years.
Considerations
Responsiveness is the lowest axis (7.9). The deep 3″ memory layer slows the spring-back; if you reposition often and want a buoyant, easy-to-pivot surface, a firmer bed in the lineup will suit you better.
It's a tall, deep bed at 16″. The plush 3″ comfort layer is the reason for the slow rise and the deeper cradle; sleepers who want a firmer, more on-top feel should consider a lower-profile model.
How It Performs — The Measured Detail
Feel & Firmness · 5/10 Medium
A balanced medium that cradles without swallowing you. 2.5″ of conforming memory foam in the deepest comfort layer of its group sits over 1000 pocketed coils, so you get an enveloping, wrapped feel with the support to stay on top. The character is plush and settle-in rather than springy — the bed holds its shape under you instead of pushing back.
Cooling 9.4
The World Class 16″ Pillow Top peaks in the 29.1-31.9 °C range and settles back into the 23.3-27.5 °C range once you're off it, with the rise over baseline held to the 7.1-9.9 °C range — the number that tells you whether a mattress banks your heat or lets it go. The InfiniCool MAX cover wicks warmth at the surface while the 1000-coil pocketed core keeps air circulating beneath, the opposite of the heat-hoarding you get from a thick foam slab. For a deep, plush medium bed, that's an actively temperature-releasing build.
Pressure Relief 9.6
A top result, and the build explains it. The surface sinks into the 2.44-3.45 inch range and settled near three inches under a lying body — well past the field average — giving an enveloping cradle that spreads load across the shoulders and hips while the 1000 pocketed coils flex under the heaviest points. It takes pressure off the joints without giving up the on-top support a medium feel provides, which suits side and combination sleepers especially well.
Motion Isolation 8.9
This was the standout reading on the bed — the best in its group. Peak transfer acceleration stayed in the 2.78-6.08 m/s² range and came in right at the floor of it, a fraction of the typical hybrid where lower means steadier, with disturbances settling in well under a second. A partner climbing in or turning over is almost imperceptible from the other side. The 1000 individually pocketed coils — the highest count in this bed's class — each flex alone instead of transmitting movement across a linked grid, paired with a generous 3″ memory-foam layer that absorbs the disturbance the moment it lands.
Edge Support 9.3
Tested near the top of its range. Loaded at the perimeter the side sank into the 2.72-4.78 inch range and held around four and a quarter inches, with a foam-encased coil unit giving the sides far more firmness than a bare foam edge. The result is a perimeter you can fully use — sit on the side to put on shoes, or sleep right to the edge, without the bed caving and tipping you off. On a 16″ pillow-top that matters, because a tall plush bed with a weak edge feels unstable; here the encasement keeps the whole surface solid right up to the rim.
Responsiveness 7.9
This bed leans toward cushioned support rather than spring. Total bounce travel sat in the 7.22-12.43 inch range and measured a little over seven inches, at the lower edge of the field — the deep 3″ memory layer is doing exactly what memory foam does, cradling and slowing the surface rather than pushing back quickly. Full recovery after you lift off settles in under 3.02 seconds, a slow, deliberate rise typical of a memory-rich build. If you want a plush hug that holds its shape under you, that settle-in response is the whole point.
Off-Gassing 9.0
New-mattress odour is minimal. Off-gassing clears in under 12 hours, the CertiPUR-US certified foams are independently tested for low VOCs, and because the bed is built in Ontario and delivered flat rather than crushed in a box, no concentrated factory air is sealed inside waiting to vent. The extra foam in this 16″ build means a slightly longer settle than the thinner beds in the range, but most sleepers notice little beyond an afternoon of airing the room.
Sleep Position & Body Weight Fit
The medium 5-out-of-10 feel is the broadest fit in the lineup — back, side and combination sleepers are all well served, with the spine held level by the 1000-coil core while the surface cradles. Lighter and average-weight sleepers get the most balanced experience; heavier sleepers stay supported thanks to the heavy-gauge steel, though dedicated stomach sleepers who want maximum firmness may prefer a firmer model.

Frequently Asked
Is the BEAUTYREST World Class 16″ Pillow Top good for couples?
Yes — it's the best in its group for motion isolation, scoring 8.9. Peak transfer measured right at the floor of its range, about 2.7 m/s², so a partner climbing in or turning over is almost imperceptible from the other side. The 1000 pocketed coils flex alone and a 3″ memory layer absorbs movement on contact.
Does the World Class 16″ Medium-Firm sleep hot?
No. It scores 9.4 on cooling, peaking at 30.9 °C with the rise over baseline held to the 7.1-9.9 °C range. The InfiniCool MAX cover wicks heat at the surface while the 1000-coil core keeps air moving beneath, so even this deep 16″ build stays temperature-neutral overnight.
Is the World Class Medium-Firm too soft for back sleepers?
No. At a medium 5-out-of-10 it scores 9.2 on spinal support — the 1000 coils on heavy 13.75-gauge steel hold the hips up and the spine level. The medium feel is the alignment sweet spot for back, side, and combination sleepers alike; the cradle comes from foam, the support from the coil system.
Is this Beautyrest a springy or a slow, sink-in mattress?
It's a slow, sink-in feel — responsiveness scores 7.9, the lowest axis. The deep 3″ memory layer cradles and holds its shape rather than springing back, with full recovery taking under 3.02 seconds. If you want a buoyant, quick-to-pivot surface, a firmer model in the lineup will suit you better.
Where is the BEAUTYREST World Class mattress made and how long can I try it?
It's built in Ontario, Canada on CertiPUR-US certified, fiberglass-free foams, and comes with a 365-night sleep trial — a full year to test it across the seasons. If it isn't the right fit, return it for a refund or exchange. Delivery is free on orders over $199, and it's backed by a 10-year warranty.
