The Ortho Dr. Preferred Reserve Westbourne II Firm is built for sleepers who want their mattress to feel level, supportive, and easy to move on. Its latex, high-density memory foam, and coil construction gave us firm support without the dense, slow response of an all-foam bed. Back sleepers and stomach sleepers should get the best fit. Lighter side sleepers are more likely to feel pressure around the shoulders and hips.

Westbourne II Firm at a glance
| Mattress | Overall Score | Pros | Cons | Ideal For |
|---|---|---|---|---|
| Westbourne II Firm | 4.3/5 | Level support, quick response, sturdy edge | Limited pressure relief for lighter side sleepers | Back and stomach sleepers; couples who prefer a stable surface |
Is the Westbourne II Firm worth buying?
Yes—if support matters more to you than deep cushioning. The Westbourne II Firm kept the pelvis level, rebounded quickly after position changes, and delivered dependable edge support. It also controlled routine partner movement well for a responsive innerspring. The surface felt temperature-neutral rather than cold, and the comfort layers offered only modest contouring. Side sleepers who need their shoulder to settle deeply into the bed should choose a softer model.

How we evaluated this mattress
We combined full-night sleep with repeatable checks for support, firmness, pressure relief, temperature, motion isolation, responsiveness, and edge support. The sample measured 12 inches tall and felt like an 8 out of 10 for firmness. I switched among back, side, and stomach positions and tracked how well the bed held my hips and lower back. Marcus monitored surface temperature and tested the edge while sitting and standing. Jenna and Ethan repeated partner-movement drills from both sides of the bed. We compared those measurements with our overnight notes before assigning scores.
Our testing experience
The defining trait was the bed’s level, lifted support. While back sleeping, my hips settled slightly without pulling my lower spine out of position. On my stomach, the center of the mattress resisted sagging and kept my pelvis aligned. The comfort layers softened the first contact, but the 8/10 firmness came through quickly when I rolled onto my side; my shoulder never sank far enough to relieve pressure completely.
Position changes were easy. After we removed a 44-pound load, the surface recovered about 90% of its height in less than a second. That quick response prevented the stuck feeling common to slower memory foam, although it also made larger movements more noticeable than they would be on a dense foam bed. In three repeated partner-movement checks, small turns stayed localized; getting into bed produced a brief vibration but no prolonged shaking.
Temperature stayed controlled rather than actively cool. The surface rose about 4°F after 30 minutes of lying down and returned close to its starting temperature within 10 minutes after we got up. At the perimeter, the high-density foam encasement limited the roll-off sensation and left enough support to sleep close to the side.

Who should choose this mattress?
Choose the Westbourne II Firm if you spend most of the night on your back or stomach, like a distinctly firm surface, and want to move without sinking into slow foam. It is also a strong match for couples who use the full width of the bed and care about edge stability. Body weight matters: heavier side sleepers may compress the comfort layers enough to get adequate relief, while lighter side sleepers will feel more pushback at the shoulder. If you need cushioning first, a softer Westbourne II feel or a more conforming alternative will fit better.

Where it may disappoint
Pressure relief is the clear limitation. The surface pushes back before a lighter sleeper’s shoulder can settle fully, so staying on one side for long periods can become uncomfortable. The quick coil-and-latex response also feels livelier than dense memory foam. Although routine partner movement remained well controlled, people who wake at the slightest vibration may still prefer an all-foam mattress. Finally, the comfort policy is an exchange rather than a refund-based sleep trial, and local White Glove delivery carries a fee.
How it compares with other firm mattresses
The Westbourne II Firm is the straightforward choice for firm, level support with a responsive surface and reinforced edge. It is less customizable than the alternatives below, but its blend of latex, memory foam, and coils gives it a useful balance of light cushioning and quick movement.
Saatva Classic offers three firmness choices, a Euro top, and a dual-coil design. Choose it if you want a more traditional luxury-innerspring feel, more height options, or a cushier surface in Luxury Firm or Plush Soft. Its Firm version remains quite firm, so side sleepers should compare comfort levels carefully.
Plank Firm Luxe is a 13-inch, flippable hybrid with a firm side and an extra-firm side. It is the better option for sleepers who want the flattest, least conforming feel and the ability to change firmness by flipping the mattress. The Westbourne II adds more noticeable comfort-layer cushioning.
Avocado Green is the strongest alternative for shoppers who prioritize certified organic materials and a latex-forward feel. It is available in several comfort levels, including a firm tight top for back and stomach sleepers. Expect buoyant support, but choose one of its softer configurations if pressure relief is the priority.
How to get the best fit and feel
-
Use the full 30-night adjustment period before deciding whether the firm feel works for you.
-
If side sleeping causes shoulder pressure, try a thin, pressure-relieving topper instead of a thick plush layer that could reduce support.
-
Choose a breathable protector that does not add a padded, heat-trapping layer.
-
Rotate the mattress periodically to help the comfort materials break in evenly.
-
Use a stable foundation that meets the manufacturer’s support requirements.
-
Pair the mattress with a lower-loft pillow for stomach sleeping and a loft that keeps the neck level for back sleeping.
-
Hot sleepers should use lightweight sheets rather than expecting the cover to feel actively cold.
-
Couples should test motion near their usual sleep positions, not only in the center of the bed.
-
Check the current exchange and delivery terms before ordering, since fees and promotions can change.
FAQs
Does it feel like memory foam or a traditional spring bed?
It feels closer to a firm spring mattress. The latex and memory foam add a small amount of cushioning, but the surface responds quickly and keeps you on top of the bed.
Is the Westbourne II Firm good for couples?
Yes, especially for couples who prefer a firm bed. Small position changes stayed localized, and the sturdy edge made more of the mattress width usable. Very light sleepers may still notice larger movements.
Will it work for side sleepers?
It can work for heavier side sleepers or people who spend only part of the night on their side. Lighter side sleepers and anyone with sensitive shoulders will usually need a softer surface.
Does it sleep cool?
It sleeps temperature-neutral. The cover, latex, and coil unit provided enough airflow to match a good cooling mattress, but the surface did not feel actively cold.
