If you have ever woken up rolled toward the middle of the bed, or sore from sinking into a too-soft pillow-top, the Jamison Clarion Firm is the straightforward fix. Lie down and you stay up on the surface, level and supported, with just enough give in the quilted top to keep firm from feeling hard. It holds its shape night after night, and it is the bed back and stomach sleepers tend to point to within the first minute.
The Clarion Firm sits at 8 out of 10, where 10 is the firmest, so this is genuinely on the firm side, not a soft bed wearing a firm label. At twelve inches tall it keeps a clean, trim profile that looks right on a platform, a foundation, or a frame. If you like a flat, supportive surface and you do not want to disappear into cushion, this is your Clarion.
Support comes from a full layer of individually wrapped pocketed coils. They carry your weight point by point and push back where your hips and lower back need it, which is what keeps your spine in a more neutral line through the night. Because the coils are wrapped and work on their own, the bed also stays quiet under motion, so a partner shifting around at two in the morning does not turn into your problem. On top, a gel-infused comfort foam softens that first touch and helps moderate surface warmth, so firm does not have to mean cold or clinical. It works with standard foundations and most adjustable bases if you like to sit up and read or raise your legs.
If you sleep on your side, a true firm will likely feel hard at the shoulder and hip, and you will be happier with cushion there. The Clarion Plush, Clarion Eurotop, and Clarion Ultra Plush Pillowtop step down in firmness, and you can compare all four side by side. See the whole lineup in the Jamison collection.
A spec sheet cannot tell you whether 8 out of 10 is your kind of firm, so come lie on it. The Clarion Firm is on the floor in all five Kentucky showrooms, which means the showroom is your trial: a few quiet minutes in your real sleep position tells you more than any description. Everyone on the floor is paid the same regardless of which brand you buy, so the guidance you get is honest. Lie on it this week in Lexington, Georgetown, Somerset, London, or Richmond, with around 4.7 stars from 535 Google reviews behind the service. Once you have chosen, delivery, in-room setup, and haul-away of the old mattress are all included, and the bed is backed by a 10-year limited warranty.

Staged at 8 out of 10 where 10 is firmest, so it reads firm the second you lie down. You rest on top of the bed instead of sinking in, which is the feel back and stomach sleepers usually want.
A full layer of individually wrapped coils carries your weight point by point and pushes back where your hips and lower back need it, keeping your spine in a more neutral position all night.
A gel-infused comfort foam softens the very first touch and helps moderate surface warmth, so a firm bed still feels welcoming under your shoulder and back.
Because each coil is wrapped and works on its own, motion stays local. A partner turning over at 2 a.m. does not roll across the bed and become your problem.
At twelve inches tall it sits trim on a platform, a foundation, or a bed frame, and it leaves room for standard-depth sheets without a fight.
It pairs with standard foundations and most adjustable bases, so you can raise your head to read or lift your legs at the end of the day.
Backed by a 10-year limited warranty from Jamison, a regional maker that keeps the build straightforward and the price honest.
Across the five Kentucky showrooms, delivery, in-room setup, and haul-away of your old mattress are all part of the order.
The Clarion Firm is built the way a firm bed should be: a thin, supportive comfort layer riding on coils that do the real work, not a deep stack of foam that softens and dips over time.
Top: gel-infused comfort foam. A layer of gel comfort foam quilts the surface. It takes the hard edge off that first touch and helps moderate surface warmth, so the bed feels firm and level rather than cold or boardy.
Middle: comfort layers. Supporting foams sit between the surface and the coils to set the firm-but-not-harsh feel and pass your weight down evenly to the support unit.
Core: individually wrapped pocketed coils. A full layer of pocketed coils is the engine. Each coil moves on its own, so the bed holds you level, responds point by point as you shift, and keeps partner motion from carrying across the surface. Wrapped coils are also why a firm bed like this stays quiet.
The whole thing stands twelve inches tall and carries a 10-year limited warranty. Jamison is a regional maker, so for the exact law-tag and material details on a specific size, just ask the floor in any Kentucky showroom and they will read you the tag.
Back sleepers. This is the heart of who the Clarion Firm is for. The pocketed coils keep your hips from dropping, so your spine stays in a more neutral line and you wake up less stiff than you would on something plush.
Stomach sleepers. A firm, level surface keeps your midsection from sagging, which is the usual cause of a sore lower back for stomach sleepers. The 8-out-of-10 feel is squarely in your lane.
People who hate sinking in. If you have ever felt swallowed by a pillow-top or rolled toward the middle of an older bed, the on-top-of-the-mattress feel here is the fix.
Couples who get woken up. Wrapped coils keep one person's tossing from traveling to the other side, so a restless partner is less likely to wake you.
Heavier sleepers who want firm support. A full coil layer pushes back harder than an all-foam bed, so a firm, supportive surface tends to hold up better under more weight. Lie on it in your real position to confirm the feel is right for your body.
Look at a softer Clarion instead if you sleep on your side. Side sleepers usually want cushion at the shoulder and hip, and a true firm will feel hard on those pressure points. The Clarion Plush, Clarion Eurotop, or Clarion Ultra Plush Pillowtop step down in firmness, and you can feel all four side by side in the showroom.

Genuinely firm. It is staged at 8 out of 10 where 10 is the firmest, so you rest on top of the surface rather than sinking in. The only way to be sure 8 out of 10 is your kind of firm is to lie on it in your normal position for a few minutes, which is exactly why Jamison stays on the floor in the Kentucky showrooms.
It depends on your body and how you sleep. Many back and stomach sleepers feel best on a firmer, level surface that keeps the spine neutral. Side sleepers often do better with some cushion at the shoulder and hip. The honest answer is to feel it, so come lie on the Clarion Firm next to a softer Clarion and let your body pick.
A gel-infused comfort foam on top for a softer first touch and some heat control, supporting comfort layers in the middle, and a full layer of individually wrapped pocketed coils as the support core. It stands twelve inches tall.
It is twelve inches tall, a clean and trim profile. Standard deep-pocket sheets fit without trouble. Measure twelve inches against your frame or foundation height if you want to picture the finished bed.
The gel-infused comfort foam on top helps moderate surface warmth, and a firmer surface like this one tends to breathe a little better than a deep pillow-top because you are not sinking into the foam. If heat is your single biggest issue, ask the floor to compare it with a cooling-focused Jamison so you can feel the difference.
Motion control is very good. The coils are individually wrapped, so they move independently and keep one person's shifting from carrying across to the other side. Wrapped coils are also why the bed stays quiet under motion.
Yes. It is built for standard foundations and most adjustable bases. Tell the floor your base model, or ask in the showroom, and they will confirm the setup before delivery.
Yes, and that is the whole point of buying it locally. The Clarion Firm is on the floor in the Kentucky showrooms, so the showroom is your trial. Lie on it in your real sleep position for several minutes before you decide. Everyone on the floor is paid the same regardless of which brand you choose, so the read you get on whether this is your bed is straight.
This is why lying on it first matters. Returns are handled as an exchange for store credit toward a bed of equal or greater value, paying the difference, rather than a cash refund. Spending a few real minutes on it in the showroom, and comparing it against the softer Clarion models, is the surest way to get it right the first time.
Delivery, in-room setup, and haul-away of your old mattress are all part of the order across the Mattress Overstock showrooms in Lexington, Georgetown, Somerset, London, and Richmond. The Clarion Firm carries a 10-year limited warranty.
