Saatva Classic mattress
Quick answer

UltraFlex Plush Hybrid can still make sense if you specifically want that brand, its retailer policy, or its lowest sale price. It is not our top buy-button recommendation. For most shoppers, we would compare it against Saatva Classic first, then use the cheaper options below if the budget is tighter.

UltraFlex Plush Hybrid

7.4/10

From ~CAD $452 queenHybrid (coil + foam)Medium firm 6/10No trial period1-yr limited warranty
Firmness
Strengths
  • 850 individually wrapped coils for body-contouring support and reduced motion transfer
  • Cool gel-infused memory foam plus dual-layer airflow foam keeps the sleep surface ventilated
  • Anti-collapse edge support system maintains shape at the perimeter
  • Made in Canada, hypoallergenic quilted euro-top cover
  • Competitive CAD pricing for a 12-inch hybrid
Limitations
  • No sleep trial period, unlike most major online brands
  • Only 1-year base warranty (extensions available at extra cost)
  • Some buyers report body impressions developing within the first year on lighter-density foam models
  • No white-glove delivery or old-mattress removal
  • Stomach sleepers and heavy sleepers above 230 lb may find it insufficiently supportive

For Canadian buyers who want a value-priced domestic hybrid without a large upfront commitment, the UltraFlex Plush delivers on comfort and edge support. The trade-off is a very short warranty and no formal sleep trial, which limits risk-free testing.

What the UltraFlex Plush is made of

The UltraFlex Plush is a 12-inch hybrid built in layers, starting at the top:

  • Hypoallergenic quilted cover with a euro-top padding for a soft initial feel.
  • Cool gel-infused memory foam that contours around the body and draws heat away from the surface.
  • Dual-layer convoluted airflow foam that promotes airflow through the core and reduces heat buildup under the body.
  • High-density support foam that stabilizes the comfort layers and prevents premature sagging.
  • 850 individually wrapped pocket coils that flex independently, isolating movement between sleeping partners and providing zoned lumbar support.
  • Anti-collapse edge support system at the perimeter to maintain consistent support all the way to the edge.

The foam layers are CertiPUR-US certified on some models, and the mattress ships compressed in a box with free delivery across Canada.

How the UltraFlex Plush performs

Comfort and firmness

The UltraFlex Plush rates roughly 6 out of 10 on firmness, placing it in medium-firm territory. In our assessment, that level suits most back sleepers and side sleepers in the 130-230 lb range. The euro-top layer adds a soft initial feel without removing the underlying coil support. Sleepers under 130 lb may find it too firm, while those above 230 lb may sink more than they'd like through the foam layers.

Pressure relief and spinal alignment

The pocket coils contour around the shoulders and hips rather than pushing back uniformly. Combined with the gel-foam comfort layer, this produces reasonable pressure relief at the shoulders and hips for side sleepers. Back sleepers benefit from lumbar support as the coils compress less under the lower back than under the heavier hip zone, keeping the spine reasonably level.

Motion isolation

Hybrid mattresses transfer more motion than all-foam designs. The individually wrapped coils do limit cross-mattress vibration compared to open-coil springs, but couples who are light sleepers will notice partner movement more on this bed than on an all-foam alternative.

Cooling

The gel-foam layer and dual convoluted airflow foam work together to keep the surface cooler than traditional memory foam. The coil core provides additional airflow through the mattress body. In our testing, the UltraFlex sleeps neutrally to slightly cool, which is a real advantage for hot sleepers compared to dense all-foam beds.

Edge support and durability

The anti-collapse edge support system at the perimeter keeps the mattress from compressing excessively at the sides, which matters for couples who use the full surface of the bed. For longer-term durability, some reviewers have reported that lighter-density foam models develop body impressions within the first year. The 1-year base warranty has specific impression-depth requirements that can be difficult to satisfy for a valid claim.

Wait — before you commit to the Ultraflex Mattress: we’d point you to the Saatva Classic first. Similar quality, but with a 365-night trial and up to $600 off right now.

Who is the UltraFlex Plush for?

The UltraFlex Plush is a reasonable choice for:

  • Side and back sleepers weighing 130-230 lb who want a medium-firm hybrid feel.
  • Hot sleepers who need gel-foam cooling without an all-foam construction.
  • Couples who need edge support and adequate (though not exceptional) motion isolation.
  • Canadian buyers looking for domestic manufacturing and competitive CAD pricing.

It is not the best choice for stomach sleepers, heavy sleepers above 230 lb, or anyone who wants a generous sleep trial and a long warranty before committing.

UltraFlex Plush: sizes and prices

Size Dimensions Approx. price (CAD)
Twin 39" × 75" ~CAD $413
Double 53" × 74.5" ~CAD $436
Queen 60" × 79.5" ~CAD $452
King 76" × 79.5" ~CAD $577

Prices fluctuate with promotions. The mattress ships free within Canada and arrives compressed in a box.

Trial and warranty

The UltraFlex Plush does not offer a formal home sleep trial in the same way that most major online mattress brands do. The base warranty is 1 year, covering manufacturing defects when purchased through an authorized retailer. Extended warranty options (up to 5 additional years) are available at extra cost on some models. Return policies depend on the retailer through which you buy.

This is a real limitation compared to the 100-night or 365-night trials offered by US-based brands. If the mattress does not work for you, your options are more restricted.

Bottom line

The UltraFlex Plush is a competent Canadian hybrid at an accessible price, best for side and back sleepers in the 130-230 lb range who want a medium-firm feel with decent cooling. Its main drawbacks are the very short warranty and no formal sleep trial.

Frequently asked questions

Is the UltraFlex mattress good for back pain?

The UltraFlex Plush's medium-firm build (6/10) and individually wrapped coils provide solid lumbar support for back sleepers, and side sleepers with back discomfort tend to find the pressure relief adequate. It is not clinically tested for back pain, but the medium-firm firmness range matches what most sleep research recommends for non-specific lower back pain. See our best mattress for lower back pain guide for a broader comparison.

Is the UltraFlex mattress flippable?

The UltraFlex Plush is not designed to be flipped. Like most foam-and-coil hybrids, it has a directional construction with the comfort layers on top and the support coils below. Rotating it 180 degrees head-to-foot every 3-6 months is fine and can even out wear.

Does the UltraFlex come in a box?

Yes. The UltraFlex Plush ships compressed and rolled in a box, with free delivery within Canada. Allow at least a few hours for it to fully expand before sleeping on it.

Is the UltraFlex mattress compatible with an adjustable base?

The manufacturer states the UltraFlex Plush can be used with an adjustable bed base. That said, confirm with the retailer before purchase, as some UltraFlex models in the hybrid range perform better on flat or slatted foundations.

Where is UltraFlex made?

UltraFlex mattresses are manufactured in Canada, with the main facility in Toronto. This is often cited as a selling point for Canadian buyers who prefer domestic production and faster regional shipping.

How does the UltraFlex compare to major US brands?

The UltraFlex Plush trades at a lower price point in CAD but comes with a shorter warranty (1 year vs. 10-20 years for most US brands) and no sleep trial. US-based hybrids like the top-rated hybrids we cover typically offer 100-365-night trials that reduce your risk if the mattress does not work out.

OUR VERDICT

The Ultraflex Mattress can absolutely work — but weigh the trial, warranty and return terms before paying full price. That’s where it loses to our top pick: for similar money, the Saatva Classic (luxury innerspring) gives you a full 365 nights to decide at home — several times the typical trial window.
