The Jamison Grandview Firm 2-Sided Mattress makes a clear promise: firm, traditional support on a mattress you can actually flip. Its thin foam layers and connected-coil core create a level, responsive surface that works especially well for back sleepers and stomach sleepers. Side sleepers who need deeper cushioning and couples who wake easily when the bed moves will feel its trade-offs more quickly.

The Grandview at a Glance
| Mattress | Overall Score | Pros | Cons | Best For |
|---|---|---|---|---|
| Jamison Grandview Firm 2-Sided | 4.1/5 | Firm, stable, flippable | Noticeable motion transfer; limited pressure relief | Back and stomach sleepers who prefer little sink |
Is the Grandview Worth It?
The Grandview is a strong value for sleepers who want a firm, no-fuss innerspring rather than a thick, body-hugging comfort stack. Its two-sided construction lets you spread wear across both faces, and the fast response makes changing positions effortless. The trade-off is just as clear: shoulders and hips receive limited cushioning, and a partner’s movement travels across the connected-coil unit more readily than it would through dense foam or pocketed coils.
Who It’s For
- Back sleepers who feel best on a firm, level surface
- Stomach sleepers who need their hips to stay lifted
- Shoppers who will follow a regular flip-and-rotation schedule
Who It’s Not For
- Lighter side sleepers who need more give at the shoulders and hips
- Couples who wake when a partner rolls over or gets out of bed
- Anyone looking for a plush, slow-contouring foam feel

How We Evaluated the Grandview

Following our process for testing mattresses, I alternated between back and side sleeping, while Marcus focused on stomach support. Jenna and Ethan used the bed together to check how clearly movement crossed from one side to the other. Along with overnight comfort notes, we tracked surface temperature, pressure at the shoulders and hips, response time after removing weight, edge compression, and vibration after a controlled drop. We also flipped and rotated the mattress to judge how practical its two-sided design is in a typical bedroom.
Our Testing Experience
The firm feel was obvious as soon as we lay down. Our panel averaged it at 8/10, which matches the retailer-listed firmness. On my back, my pelvis stayed level with my rib cage instead of settling below it. Marcus noticed the same support while lying on his stomach and did not have to tense his lower back to keep his hips from dropping.
The surface gave much less at the shoulder than it did under the torso. A 44-pound load compressed the center by 1.3 inches, and my shoulder never settled far enough to feel fully cushioned during longer side-sleeping stretches. That firm contact explains the strong support score and the more modest pressure-relief result.
Changing positions was easy. After the load was removed, the surface recovered 90% of its height in 0.7 seconds, so none of us felt held in place. The connected coils were less discreet with movement: after a 15-pound ball drop from 4 inches, vibrations measured 3 feet away remained noticeable for 1.4 seconds. Jenna and Ethan could both tell when the other person rolled over, even though the mattress itself felt stable.
Heat buildup was moderate rather than distracting. The surface rose from 69.1°F to 77.4°F after 30 minutes and returned to within 2.6°F of its starting point 10 minutes after we got up. The perimeter also stayed usable; with the same load, it compressed about 0.5 inch more at 2 inches from the edge than it did in the center. Sitting there felt secure, though the border was not as rigid as the reinforced edge on some modern hybrids.
What we liked
- Firm support kept the hips level during back and stomach sleeping
- Fast recovery made rolling over and getting out of bed easy
- Two usable faces let owners distribute wear through regular flipping
Who it is best for
- Back sleepers who want steady lumbar support with little contouring
- Stomach sleepers who need a firm surface under the midsection
- People who prefer a responsive mattress and do not mind a traditional innerspring feel
Where it falls short
- Side sleepers may feel concentrated pressure at the shoulder and outer hip
- Movement travels too easily for couples who are light sleepers
- The thin comfort layers do not provide a plush or deeply cushioned feel
Where It Excels—and Where It Doesn’t
| Pros | Cons |
|---|---|
| Firm support; two-sided build; quick response; stable edge | Noticeable motion transfer; shallow cushioning; too rigid for some sleepers |

Should You Buy the Grandview?
Choose the Grandview if you mainly sleep on your back or stomach, want very little sink, and are willing to flip a mattress on a schedule. It is also the least expensive option in this comparison group based on the prices available during our research. Dedicated side sleepers and motion-sensitive couples should look elsewhere. The Nectar Premier Memory Foam provides deeper contouring and quieter motion control, while the Plank Firm Luxe preserves the flippable, extra-firm idea in a more expensive pocketed-coil hybrid.
What to Know Before Buying

The Grandview’s firm surface leaves little room for pressure points to settle, so side sleepers may feel soreness at the shoulder or hip during a full night. Its connected-coil core also transfers more movement than a strong motion-isolation mattress with dense foam or individually wrapped coils. Finally, this exact Grandview is sold through select regional retailers rather than a consistent nationwide storefront, so stock, delivery options, and pricing depend on where you shop.
How It Compares With Popular Alternatives
Why choose the Grandview
- You want two sleepable sides at a comparatively low listed price
- You prefer firm, stable support with very little sink
- You want faster movement than memory foam provides
Plank Firm Luxe gives you Firm and Extra Firm faces rather than two matching firm surfaces. Its pocketed-coil hybrid build controls movement better and feels more refined at the edge, but it costs considerably more. It is the closest alternative for someone who likes the Grandview’s flippable concept and wants a more modern construction.
The WinkBed in Firmer adds a Euro pillow top, individually wrapped coils, and stronger contouring without becoming soft. It feels more cushioned and has a more substantial edge than the Grandview, but it is one-sided and sits in a much higher price tier. Choose it when you want firm support without the Grandview’s spare, traditional feel.
Nectar Premier Memory Foam takes the opposite approach. Its slow-contouring foam absorbs partner movement and eases pressure at the shoulder and hip far better than the Grandview. In return, it feels less responsive, lacks a flippable design, and costs more. It is the better fit for side sleepers and couples who value a quiet surface over bounce.
How to Get the Best From It
- Flip and rotate the mattress every three months so both faces and all sleep zones share the wear.
- Use a rigid, level foundation that meets the warranty terms.
- Allow a few weeks to adjust if your current mattress is noticeably softer.
- Try a thin, breathable topper if you only need a little more cushioning for side sleeping.
- Choose a pillow height that keeps your neck level on the firmer surface.
- If partner movement wakes you, increase the distance between sleepers when the bed size allows.
- Use breathable bedding rather than a thick, heat-trapping pad.
- Ask the retailer to confirm stock, delivery fees, and the exact RST454 construction before ordering.
- Protect both faces with a fitted mattress protector so each side remains usable.
Grandview FAQs
Does the Grandview soften over time?
The foam layers should relax slightly with regular use, but the mattress will remain firm. Flipping and rotating it helps both faces break in and wear more evenly.
Is it comfortable for side sleeping?
It works for occasional side sleeping, but most dedicated side sleepers will need more give around the shoulder and hip. The firm surface is especially demanding for lighter sleepers.
Is it a good mattress for couples?
It is responsive and easy to move across, but its connected coils pass along more motion than dense foam or pocketed coils. Couples who sleep lightly may notice each other changing positions.
