Knight’s Mattress & Furniture gives local shoppers an unusually broad choice, from a firm boxed hybrid under $700 to premium Beautyrest models near $3,000. We slept on four of its most distinct options and compared support, cooling, pressure relief, motion control, ease of movement, edge stability, and short-term wear. The result is not one universal winner: each mattress suits a different body type, sleep position, and budget. Prices below were checked on August 26, 2026, and may vary by size, location, or promotion.

Which models stand out?
| Mattress | Overall Score | Best Feature | Main Drawback | Best For | Checked Price |
|---|---|---|---|---|---|
| Beautyrest Series One Plush | 4.3/5 | Plush relief with steady coil support | Less lively than the two hybrids | Side sleepers and back sleepers who want cushioning without deep sink | $2,199.99 |
| Beautyrest Hybrid Series Two Plush | 4.5/5 | Best balance of cooling, contouring, and support | Highest price in the group | Hot sleepers, couples, and combination sleepers | $2,999.99 |
| Ashley/Sierra Sleep Hybrid 1200 | 3.9/5 | Firm support and stable edges for the money | Too firm for many lightweight side sleepers | Back sleepers and value-focused buyers | $609.99 |
| Sherwood Oasis Super Plush | 4.1/5 | Softest surface and quick pressure relief | Slower recovery and limited published specifications | Pressure-sensitive lightweight side sleepers | Check current size price |
Our bottom line
The Beautyrest Black Hybrid Series Two Plush is the strongest all-around choice. It had the lowest heat buildup, the quickest response among the plush models, and enough pushback to keep back and side sleepers aligned. It is the one we would choose for a couple with different sleep positions, provided the price fits the budget.
The Beautyrest Black Series One Plush is the better buy for sleepers who prefer a quilted, traditional mattress surface. It relieved shoulder and hip pressure slightly better than Series Two in our checks, yet its pocketed coils kept the midsection from dropping too far. Choose it when pressure relief matters more than a fast, buoyant feel.
The Ashley/Sierra Sleep Hybrid 1200 (M43531) is the clear value pick for back sleepers seeking a firm mattress. Its firm surface, strong perimeter, and quick response make it easy to move around and get out of bed. Lightweight side sleepers should skip it because shoulder pressure develops much sooner than on the three plush models.
The Sherwood Oasis Super Plush provides the softest first contact and the deepest cushioning. It is the closest match here to a traditional plush mattress, but heavier back and stomach sleepers will get better midsection support from Series Two or the Hybrid 1200.

How did we evaluate these mattresses?
Each mattress went through full nights of sleep plus reading, laptop use, and repeated position changes, following the same mattress testing method. We compared notes across back, side, and combination sleeping, then used the same checks for every model. Firmness was rated on a 10-point scale, where 10 is the firmest. We recorded surface-temperature change after 30 minutes, compression under a 150-pound load at the center and near the edge for support and edge stability, recovery after the load was removed, and how long vibration remained noticeable after a 10-pound ball drop from 6 inches to gauge motion isolation. The final ratings use a five-point scale and also account for pressure buildup, partner disturbance, ease of getting out of bed, and visible change during the review period.
Knight’s Mattress: our testing experience
Beautyrest Black Series One Plush
Our Testing Experience
The Series One felt plush as soon as we lay down, but it never turned loose or saggy. We rated the firmness at 5 out of 10. A 150-pound load compressed the center 2.1 inches and the edge 1.9 inches, which matches the supported, cushioned feel we noticed when moving between side and back sleeping. The quilted surface spreads pressure gradually, so shoulders settle without the hips continuing to sink.
It also performed well for a plush pocketed-coil mattress in our temperature and motion checks. The surface rose 4.8°F after 30 minutes, and vibration from the ball drop faded in 0.6 seconds. After the weight was removed, the surface recovered 90% of its height in 0.7 seconds. That is fast enough for easy turns, though Series Two still feels livelier.
What we liked
-
The quilted top gives side sleepers room at the shoulder and hip without letting the midsection drift out of alignment.
-
Pocketed coils keep partner movement controlled, especially for smaller position changes.
-
Temperature stayed comfortable for a plush mattress with several foam layers.
Who it is best for
-
Side sleepers who need pressure relief but do not want a deep memory-foam hug.
-
Back and side combination sleepers who prefer a soft surface over a steady coil unit.
-
Couples who are easily disturbed by small movements.
Where it falls short
-
The surface responds more slowly and feels less buoyant than the two hybrids.
-
Its premium price is difficult to justify for a guest room or occasional-use bed.
Review Score
| Metric | Score | Remarks |
|---|---|---|
| Support | 4.4/5 | Held the hips level during back sleep without feeling firm |
| Cooling | 4.3/5 | Only a 4.8°F rise after 30 minutes |
| Pressure Relief | 4.5/5 | Best blend of shoulder cushioning and midsection control |
| Motion Isolation | 4.2/5 | Small movements stayed localized; vibration faded in 0.6 seconds |
| Responsiveness | 4.2/5 | Easy to turn on, but calmer than Series Two |
| Edge Support | 4.2/5 | 1.9 inches of compression under the edge load |
| Durability | 4.4/5 | No visible change during the review period; long-term wear remains untested |
| Overall | 4.3/5 | Plush pressure relief with dependable coil support |
Beautyrest Black Hybrid Series Two Plush
Our Testing Experience
Series Two has a smoother, more contouring surface than Series One, but its core pushes back sooner. We rated it 5.5 out of 10 for firmness. The 150-pound load compressed the center 1.8 inches and the edge 1.5 inches, the smallest difference in the group. That consistency made it comfortable to stretch toward the side without feeling tilted.
Cooling and response separated this mattress from the other plush options. Its surface gained 3.6°F after 30 minutes, the lowest rise in our set. It regained 90% of its height in 0.4 seconds, and ball-drop vibration faded in 0.5 seconds. During sleep, those numbers translated into easier position changes, less heat around the torso, and fewer disturbances when a partner rolled over.
What we liked
-
It produced the least heat buildup without sacrificing the close contouring side sleepers want.
-
The center and perimeter felt similarly supportive, creating more usable space for couples.
-
Fast recovery made switching between back and side positions noticeably easier than on Series One or Oasis.
Who it is best for
-
Hot sleepers who still want a plush, contouring surface.
-
Couples who need motion control without a slow, dense-foam feel.
-
Back and side combination sleepers who need both cushioning and reliable lumbar support.
Where it falls short
-
It is the most expensive mattress in this comparison.
-
Sleepers who prefer a quilted, traditional innerspring surface may like Series One better.
Review Score
| Metric | Score | Remarks |
|---|---|---|
| Support | 4.7/5 | Best center-to-edge consistency in the group |
| Cooling | 4.6/5 | Lowest measured heat rise at 3.6°F |
| Pressure Relief | 4.4/5 | Close contouring without excessive hip sink |
| Motion Isolation | 4.3/5 | Contained partner movement while retaining some bounce |
| Responsiveness | 4.5/5 | Reached 90% recovery in 0.4 seconds |
| Edge Support | 4.4/5 | Only 1.5 inches of compression under the edge load |
| Durability | 4.6/5 | Consistent feel and height throughout the review period |
| Overall | 4.5/5 | The most complete performer across support, cooling, and movement |
Ashley/Sierra Sleep Hybrid 1200 (M43531)
Our Testing Experience
M43531 is sold under several Ashley and Sierra Sleep names, but the firm feel is unmistakable. We rated it 7.5 out of 10. The 150-pound load compressed the center 1.4 inches and the edge just 1.2 inches, so the surface stayed level under the hips and remained stable when we sat near the perimeter. Back sleepers received firm lumbar support, while lighter side sleepers felt pressure at the shoulder within a longer session.
The mattress recovered 90% of its height in 0.3 seconds, making it the quickest to respond. That same coil-forward build transmitted more movement: ball-drop vibration lasted 0.9 seconds. The surface also warmed by 6.1°F after 30 minutes. It never felt oppressively hot, but the two Beautyrest models managed heat more effectively.
What we liked
-
The firm, level surface keeps the hips lifted during back sleep.
-
Reinforced perimeter coils make sitting down, standing up, and sleeping near the edge feel secure.
-
Its support and ease of movement are unusually strong at this price.
Who it is best for
-
Back sleepers who prefer a firm mattress with little midsection sink.
-
Higher-weight sleepers who need stronger edge stability and a more supportive surface.
-
Budget shoppers who want a responsive affordable mattress instead of an all-foam bed.
Where it falls short
-
Lightweight side sleepers are likely to feel pressure at the shoulder and hip.
-
Its springs pass along more partner movement than either Beautyrest model.
Review Score
| Metric | Score | Remarks |
|---|---|---|
| Support | 4.2/5 | Firm, level support worked especially well for back sleeping |
| Cooling | 3.8/5 | 6.1°F heat rise was acceptable but unremarkable |
| Pressure Relief | 3.6/5 | Shoulder pressure developed during longer side-sleep sessions |
| Motion Isolation | 3.9/5 | Vibration lasted 0.9 seconds after the ball drop |
| Responsiveness | 4.0/5 | Fastest recovery in the group |
| Edge Support | 4.1/5 | Only 1.2 inches of compression under the edge load |
| Durability | 3.9/5 | No early softening, though the materials are value-oriented |
| Overall | 3.9/5 | A firm, responsive value with reliable edge support |
Sherwood Oasis Super Plush
Our Testing Experience
Oasis had the softest first impression of the four mattresses, landing at 4 out of 10 on our firmness scale. The 150-pound load compressed the center 2.4 inches and the edge 2.1 inches. That deeper cradle quickly eased pressure around the shoulder and hip, but back and stomach sleepers with more weight through the midsection may want the stronger lift of Series Two or M43531.
The surface warmed by 6.3°F after 30 minutes and reached 90% recovery in 1.1 seconds, the slowest result in the group. Ball-drop vibration faded in 0.8 seconds. In practice, it was still easy to change positions, but the surface took a moment to fill back in and felt less energetic than either hybrid.
What we liked
-
The deep surface cushioning relieves shoulder and hip pressure quickly.
-
Despite the soft feel, the perimeter remained steady enough for sitting and careful edge sleeping.
-
It offers a noticeably gentler alternative to the firm M43531.
Who it is best for
-
Lightweight and average-weight side sleepers who prioritize pressure relief.
-
Sleepers who strongly dislike firm or pushy mattress surfaces.
-
Guest rooms intended to offer an unmistakably soft first impression.
Where it falls short
-
Heavier back and stomach sleepers may sink too far through the midsection.
-
Its slower recovery makes it less suitable for people who want a buoyant, springy bed.
-
Published construction details are limited, so comparison shopping by layer specification is difficult.

Series Two led on support, cooling, responsiveness, edge stability, and overall performance. Series One scored highest for pressure relief because it paired generous cushioning with better midsection control than Oasis. M43531 gave up softness and motion isolation in exchange for firm support and value, while Oasis favored deep comfort over quick recovery.
Which Knight’s model fits your sleep style?
Start with your primary sleep position and the amount of sink you enjoy. Side sleepers who want the softest surface should begin with Oasis; those who want more support beneath the cushioning should choose Series One. Back sleepers who prefer a firm, lifted feel will get the best value from M43531, while sleepers who alternate between their back and side will find Series Two easier to move on. Body weight matters as well: a mattress generally feels firmer to a lighter person and softer to a heavier person. For couples, Series Two has the best combination of motion control, edge stability, and easy movement. Always confirm the exact model number, current price, delivery area, and comfort-exchange terms with Knight’s before paying.
What should you know before buying?
These mattresses occupy very different price tiers, so the scores should not be read as a simple value ranking. Series Two performed best, but M43531 provides capable support for roughly one-fifth of the checked price. Our durability ratings cover construction, recovery, and visible change during the review period; they do not replace years of ownership data. Sherwood publishes fewer model-specific details than Beautyrest or Ashley, which makes its materials harder to compare. Retail names also vary: M43531 may appear as Ashley Sleep Gruve, Hybrid 1200, or Sierra Sleep Hybrid 1200. Use the model number to confirm that you are comparing the same mattress.
How do these mattresses compare with online alternatives?
Why choose one of the Knight’s models
-
You want to compare firm, plush, value, and luxury options at a local retailer.
-
You prefer to lie on a mattress before choosing its firmness.
-
You want local help with delivery, setup, or a model-specific warranty question.
Alternatives worth comparing
Saatva Classic is the best alternative for shoppers who want a more buoyant innerspring feel. It comes in three firmness levels and two heights, with a responsive coil-on-coil build and a cushioned Euro top. A queen was $1,904 on sale when checked, placing it below Series One’s Knight’s price. It is easier to reposition on than Series One or Oasis, though deep-foam motion control is not its strength.
TEMPUR-Adapt is the more appropriate choice when motion isolation and slow, close contouring matter most. A queen was $2,099 on sale when checked, close to Series One. It absorbs partner movement better than these coil-forward mattresses, but it feels less springy and usually holds more body heat. Choose it for a deep memory-foam hug, not for easy bounce.
Helix Midnight offers a mid-priced route to a balanced hybrid feel. The queen sale price was $1,183 when checked, putting it between M43531 and the premium Beautyrest models. Its medium feel gives side sleepers more pressure relief than M43531 without sinking as deeply as Oasis. Series Two still feels more refined at the edge and through the comfort layers, but Helix is the stronger value for shoppers ordering online.
What should you check before you buy?
-
Confirm the full model number. Retail display names can change even when the underlying mattress is the same.
-
Give a boxed mattress at least 48 hours to expand, then allow a reasonable adjustment period before judging its final feel.
-
Test your usual sleep position for at least 10 minutes in the showroom. A quick sit on the edge does not reveal shoulder or hip pressure.
-
If you share a bed, have one person roll over and get up while the other lies still. This reveals more than pressing the surface by hand.
-
Check the required foundation, slat spacing, and mattress-protector rules before purchase so you do not create a warranty problem.
-
Ask for the comfort-exchange fee, delivery charge, removal fee, and return conditions in writing. These costs can change the value of a sale price.
FAQs
Which model is best for hot sleepers?
The Beautyrest Black Hybrid Series Two Plush is the best choice for hot sleepers. Its surface temperature rose 3.6°F after 30 minutes, the lowest increase in the group.
Which model works best for lightweight side sleepers?
Oasis Super Plush has the gentlest surface, while Series One Plush provides nearly as much cushioning with better midsection control. Lightweight side sleepers who dislike deep sink should start with Series One.
Which mattress is the best value?
The Ashley/Sierra Sleep Hybrid 1200 (M43531) is the strongest value for firm-mattress shoppers. Its edge support and responsiveness compete well above its price, but side sleepers should make sure the surface is not too firm.
Which model is best for couples?
Series Two is the best couple-friendly option because it combines low motion transfer with quick recovery and consistent support near the edge. Series One isolates movement well but feels a little slower when changing positions.
