Sealy Posturepedic Plus Opportune II
7.4/10
- 911 individually wrapped coils reduce motion transfer better than open-coil designs
- Dura-Flex foam-encased coil edge holds its shape when sitting or sleeping near the border
- Zoned gel memory foam targets lumbar and core support
- Sealy Cool Air gel foam and ComfortLoft cover keep the sleep surface cooler than standard foam
- Adjustable-base compatible without voiding the warranty
- No published sleep trial, which limits your ability to evaluate it risk-free at home
- 10-year warranty is shorter than most direct-to-consumer competitors
- Side sleepers may find the cushion-firm feel short on hip and shoulder pressure relief
- Lightweight sleepers (under 130 lb) report the coil response can feel stiff
In our testing, the Opportune II is a solid mid-range spring mattress for back and stomach sleepers who prefer a responsive, lightly contoured feel. The zoned coil layout and Dura-Flex edge give it a more structured support profile than budget spring beds, though the absence of a trial window is a genuine drawback compared to online competitors.

What the Sealy Posturepedic Plus Opportune II is made of
The Opportune II is a 13-inch encased-coil mattress, not an all-foam bed. The construction from top to bottom runs like this:
- ComfortLoft knit cover with SealyChill cooling treatment and allergen protection.
- Sealy Cool Air Gel foam (roughly 2 inches) and a thin Sealy Cool Gel Memory Foam zone (around 0.5 inches) in the center third, adding targeted lumbar support.
- SealySupport Gel Foam transition layers that bridge the comfort foams to the coil base.
- Response Pro Encased Coil System, approximately 911 individually wrapped coils in queen. Each coil responds independently, reducing cross-mattress motion transfer compared to open-coil designs.
- Dura-Flex Coil Edge System: foam-reinforced coil perimeter that prevents the rolling-off sensation common on older innerspring beds and adds usable sleeping surface near the edge.
The mattress is not flippable. It ships compressed in a box, which simplifies setup, and is designed to work with adjustable bed frames without voiding the warranty.
Sealy manufactures the Opportune II in the USA using a combination of domestic and imported materials, and the Posturepedic Plus line is positioned above Sealy's entry-level Hybrid tiers.
Comfort and firmness
The Opportune II comes in Soft/Plush, Medium (Cushion Firm), and Firm variants. The Medium is the most widely available version and feels close to a 5 out of 10 on a standard firmness scale, which is standard medium. Back sleepers get enough support to maintain a neutral lumbar curve without pressure buildup. Stomach sleepers find the firmer response useful for keeping the pelvis from tilting into excessive arch.
Side sleepers are a tougher fit. The cushion-firm feel provides a limited amount of hip and shoulder pressure relief, and sleepers with narrow shoulders or sensitive joints may find the surface too unyielding. If you sleep primarily on your side, a softer foam or latex layer tends to work better. See our guide to mattresses for side sleepers for options built around pressure relief first.
Performance details
Motion isolation
The 911 individually encased coils do a reasonable job of absorbing localized movement before it crosses the mattress. In our testing, the transfer was noticeably lower than open-coil innerspring beds, though still higher than pure-foam or latex constructions. Couples where one partner is a light sleeper may prefer a foam-dominant design for better isolation.
Edge support
The Dura-Flex coil edge is one of the Opportune II's genuine strengths. Sitting on the perimeter produces less sinkage than many comparable hybrid beds, and sleepers who use the full width of the mattress do not encounter the roll-off feeling that weakens older innerspring edges. This makes it a practical choice for anyone who needs reliable edge-to-edge surface.
Cooling and breathability
The open-coil support base promotes airflow from below, and the SealyCool gel foam layers moderate heat buildup better than dense memory foam. The ComfortLoft cover stays cool to the touch initially. Sleepers who run very hot may still notice some warmth from the foam comfort layers during the night, but on balance the Opportune II sleeps cooler than most all-foam beds in the same price range. See our best cooling mattress picks if temperature is your primary concern.
Back pain and spinal support
The zoned gel memory foam in the center third of the mattress targets lumbar and core support, which is the engineering logic behind the Posturepedic branding. For people with non-specific lower back pain who sleep on their back, this zoning can help maintain a neutral spine position through the night. The firmer Posturepedic Plus coil base resists the deep sinkage that leads to morning stiffness for back sleepers. See our guide to mattresses for back pain for a wider comparison.

Trial, shipping, and warranty
Sealy does not publish a standard home sleep trial for the Posturepedic Plus line through its retail partners, which is a meaningful gap compared to the 100 to 365-night trials standard among direct-to-consumer brands. The Opportune II carries a 10-year limited warranty covering manufacturing defects and body impressions deeper than 1.5 inches. Shipping is free across the continental US.
The 10-year non-prorated warranty is shorter than what most online-first competitors offer. If a long, risk-free trial window and warranty coverage matter to you, this is worth weighing against the purchase.
Who the Sealy Opportune II suits
The Opportune II is a good match if you want:
- A traditional spring feel with moderate foam contouring, rather than deep memory foam hug
- Reliable edge support for sitting on the bed or using the full mattress width
- A back or stomach sleeping position, or combination sleeping that spends most time off your side
- A body weight above 130 lb, where the coil response produces a balanced, supported feel
It is a less natural fit for pure side sleepers, very lightweight sleepers, or anyone who prioritizes a long home trial window before committing.
A note on model refreshes
When a Sealy model gets a version II update, the prior version often goes on clearance at 30 to 50 percent off. Since the Posturepedic Plus support coil system is typically unchanged between generations, the clearance version can represent solid value if you find your preferred firmness and size still in stock.

The Sealy Posturepedic Plus Opportune II is a well-built mid-range spring mattress for back and stomach sleepers who want zoned coil support and reliable edge performance. The main trade-offs are the lack of a sleep trial and a shorter warranty than most direct competitors.
Frequently asked questions
Is the Sealy Posturepedic Plus Opportune II good for back pain?
For back sleepers with non-specific lower back pain, the zoned gel memory foam center and encased coil base help maintain a neutral spine position. The cushion-firm feel hits a useful medium between too-soft (which lets the hips sink and arch the lumbar) and too-firm (which prevents the pelvis from settling). Side sleepers with back pain may need more pressure relief than the Opportune II provides.
Does the Sealy Posturepedic Plus Opportune II come in a box?
Yes. It ships compressed in a box for easier transport and setup.
Is the Sealy Posturepedic Plus Opportune II flippable?
No. The Opportune II is a one-sided mattress. Rotating it head-to-foot every six months is recommended to even out wear.
Can I use it with an adjustable base?
Yes. The Opportune II is compatible with adjustable bases and Sealy states this does not void the warranty.
Is there a sleep trial?
Sealy does not publish a standard home trial for this model through most retail partners. Check the specific retailer's return policy before purchasing, as policies vary.
