Posh+Lavish Premier Medium Firm Review

The Premier Medium Firm is a strong choice for sleepers who want their mattress to hold them up rather than wrap around them. Its latex-and-coil construction kept our hips level on our backs and made every position change feel quick. The edge also stayed composed while sitting or sleeping near the side, which makes the surface feel more usable.

That responsiveness is also its main drawback. Turns are easier to notice across the bed than they are on slow-moving foam, and the unquilted top does not provide a soft initial cushion. It earns its 4.3/5 overall score through support, edge stability, and ease of movement—not plushness or exceptional motion isolation.

• Who it suits

  • Back and combination sleepers who prefer a lifted, medium-firm surface

  • People who change positions often and do not want to feel stuck

  • Anyone who regularly sits or sleeps near the edge

• Who should skip it

  • Motion-sensitive couples who want the calmest possible surface

  • Side sleepers who need a soft cradle around the shoulder and hip

  • Anyone who prefers the slow contour of a memory foam mattress or a thick pillow top

Marcus, Jenna, and Ethan used the mattress over several weeks, comparing how it felt across different body sizes, sleep positions, and sensitivity to a partner’s movement. Along with nightly notes and our standard mattress testing method, the checks covered surface firmness, support, pressure relief, temperature, motion transfer, response time, and edge compression. Each mechanical check was repeated three times and averaged so a single reading did not determine the result.

The first thing we noticed was how little cushioning sits above the support system. Our sample measured 10.9 inches tall and felt like a 7/10 for firmness: solidly medium-firm, with latex springiness rather than a hard, flat surface. On my back, my hips settled just enough to keep my lower back supported. Marcus (6'1", 230 pounds) also stayed level when he rolled toward his stomach, without the midsection dip he noticed on softer hybrids.

The response was quick. After we removed a 44-pound load, the surface recovered 90% of its height in 0.4 seconds, which matched how easy it felt to roll from one side to the other. Jenna (5'7", 160 pounds) never needed to push against the bed to turn. Ethan (6'0", about 188 pounds) could follow those turns from the other side, though. The pocketed coils kept the bed from shaking sharply, but the latex rebound carried more movement than a slow all-foam surface.

Edge support was one of the clearer strengths. Under the same 44-pound load, the center compressed 1.4 inches and the area two inches from the edge compressed 1.7 inches. That small difference lined up with Marcus’s experience sitting there to put on shoes: the border flexed but never felt as if it would slide him forward. Temperature control was similarly steady. The surface rose 5.1°F after 30 minutes and returned to within 1.3°F of its starting temperature 10 minutes after we got up, so it held less residual warmth than dense memory foam beds in the same room.

• What we liked

  • The midsection stays supported without making the whole surface feel rigid.

  • Fast rebound makes turning and getting out of bed noticeably easier.

  • The perimeter remains dependable enough for sitting and sleeping near the side.

• Who it is best for

  • Back and combination sleepers who want medium-firm support with minimal sink.

  • People with limited mobility who benefit from a responsive surface and a stable edge.

  • Sleepers who tend to overheat on dense foam but still want some pressure relief.

• Where it falls short

  • Light turns remain noticeable to a sensitive partner.

  • Dedicated side sleepers may need more cushioning around the shoulder.

  • The unquilted top feels direct and may disappoint shoppers expecting a plush first impression.

• Availability and price: Sold through specialty dealers; inventory, price, delivery, trial, exchange, and return terms vary by seller

• Firmness: Medium-firm; 7/10 in our evaluation

• Height: 11 inches listed; 10.9 inches measured on our sample

• Surface: Unquilted

• Cover: 602-gram Tencel-faced fabric

• Comfort layer: Oeko-Tex-certified latex

• Support core: Pocket springs; 1,068 coils listed for queen

• Fire barrier: Wool and cotton

• Flippable: No

• Adjustable-base compatible: Yes

• Warranty: 10-year limited warranty

Choose the Premier if you already know you like a responsive, medium-firm mattress and want stronger support than a plush hybrid provides. It is particularly well suited to back sleepers, combination sleepers, and anyone who relies on the edge when getting in or out of bed. A lighter side sleeper or a couple that wakes easily when the other person turns should prioritize deeper cushioning or stronger motion isolation.

• Choose Zenhaven if you want an all-latex mattress with two usable firmness sides. Its Gentle Firm side feels firmer than the Premier, while the Luxury Plush side offers more contouring. It also comes with a direct-to-consumer trial and warranty rather than dealer-specific policies.

• Choose PlushBeds Luxury Bliss if you want a 12-inch latex hybrid with a thicker comfort profile, Medium and Med-Firm choices, and a lower typical promotional price. It is the more flexible option for shoppers who are unsure about the Premier’s direct, unquilted feel.

Dealer-based sales make this mattress less straightforward to compare online. Confirm that the law tag and invoice identify the Premier Medium Firm, because current Posh+Lavish catalogs may use different names and specifications for other pocket-sprung models. Ask the seller for the exact price, comfort-exchange window, return fees, delivery terms, and warranty requirements in writing.

Its feel also has clear limits. The top is responsive rather than plush, and partner movement is easier to notice than on slow-moving foam. Side sleepers who need substantial shoulder sink may find it too firm. Our durability score reflects material quality and stability during the review period, not years of ownership.

The Premier makes the most sense when you want a direct latex-and-coil feel, strong edges, and quick movement. Its unquilted surface feels more lifted than cushioned, and its dealer-based purchase terms require more homework before buying.

Zenhaven Gentle Firm is the firmer alternative. It uses an all-latex, flippable design rather than coils, with a softer Luxury Plush side available on the reverse. Pick it for two comfort options, a firmer upper range, and standardized direct-purchase policies; stay with the Premier for the familiar lift and edge structure of pocketed coils.

PlushBeds Luxury Bliss Med-Firm is the more cushioned latex-hybrid alternative. Its 12-inch build combines a thicker quilted surface, latex, and encased coils, and it usually costs less during promotions. It is better for shoppers who want a choice of firmness and a gentler first contact, while the Premier feels flatter, quicker, and more supportive at the perimeter.

• Use a rigid, evenly supported foundation or platform that meets the dealer’s warranty requirements.

• Spend at least 15 minutes in your normal sleep positions before buying in a showroom; latex feels different after your body settles.

• Rotate the mattress from head to foot on the schedule recommended by the seller to distribute wear.

• Avoid thick, soft pads if you want to preserve the mattress’s quick response and stable edge.
