The firm hybrid for people who mean firm
The honest verdict: the Apex Pro Cushion Firm is for the back or stomach sleeper who wants to rest on top of the bed, not in it, and who is done with "firm" mattresses that turn medium after a month. Jamison marks this one Extra Firm on its own spec sheet. On the 10-point scale used here, where 10 is the firmest, it is an 8. That is a real firm with a thin cushion at the surface, so the first inch or so gives a little before the ComfortFirm Foam and the coils take over and hold you level.
At thirteen inches it is the tallest firm model in the Sleep Response line, and it is the firm member of the copper-cover hybrid trio. The Elevate Plush is the soft one at a 4, and the Fusion Elite splits the difference at a 6. If you are choosing between the three by feel alone, this is the one that keeps you flat.
What "cushion firm" means in this build
Top down: an InfinityChill Copper Cover, cool to the touch, with copper-infused fibers that are naturally antimicrobial. Under it, Safe Slumber fire retardant fibers meet the federal open-flame standard without chemical sprays. Then Gel Cooling Foam and QuiltSoft Foam with gel, and those two are the cushion. A layer of ComfortVisco memory foam sits beneath them for a bit of contour at the shoulders and hips. Then the layer that separates this bed from the Elevate: ComfortFirm Foam, a firm transition layer that stops you before you reach the coils. The QuantumEdge individually wrapped coil system carries the load, and HD Base Foam anchors the build. The cushion is the top two foams. The firm is everything under them.
Who it fits
Back sleepers who want a level surface and stomach sleepers who need their hips held up are the target. Heavier sleepers tend to do well here because the ComfortFirm layer and the coils resist sinking. If you share the bed, the wrapped coils keep one side's movement from crossing over. Side sleepers usually find an 8 hard on the shoulder, and for them the Elevate Plush or the Fusion Elite is the better read. If you want firm without coils, the all-foam Premier Firm is a 7 out of 10 at eleven and a half inches.
How buying it online from Mattress Overstock works
The Apex Pro is an online exclusive. It is not on any Mattress Overstock showroom floor right now, so there is nothing to lie down on in person, and this page has to do the work a floor visit normally does. If you need to feel a firm Jamison before you buy one, the showroom lineup at Jamison Bedding includes firm models you can try in a Kentucky store. Everyone at Mattress Overstock is paid the same no matter which bed you buy, so the recommendation to read the firmness notes twice is not a sales tactic.
Shipping is free to the contiguous United States, the 48 states plus Washington, DC, and not available to Alaska, Hawaii, or United States territories. The mattress ships direct from Jamison's factory via UPS, arrives compressed and roll-packed, and tracking is emailed to you. Jamison covers it with a 10-year full warranty, and every Sleep Response model comes with a 60-day comfort trial, exchange only, with no cash refunds. If the feel is wrong within 60 days of delivery, email help@mattressoverstock.us and the team will set up an exchange for store credit toward a mattress of equal or greater value. You pay any price difference. Warranty or damage questions after delivery go to the same address. Jamison has been handmade in the USA since 1883, and Sleep Response is the factory-direct line built to ship from plants in Ohio, Georgia, Texas, and South Carolina.
What makes this mattress different
Genuinely firm, rated 8
Jamison marks the Apex Pro Extra Firm on its own scale. On the 10-point scale used here, it is an 8, so you rest on top of the surface instead of settling into it.
Thin cushion, firm build
Gel Cooling Foam and QuiltSoft Foam with gel give the first inch or so a little softness. Under them, ComfortFirm Foam and wrapped coils hold you level. That is what cushion firm means.
Copper cover, cool to the touch
The InfinityChill Copper Cover uses copper-infused fibers that are naturally antimicrobial and feel cool when you first lie down, which pairs well with a firm bed that already traps less heat.
Wrapped coils, quiet nights
Each QuantumEdge coil sits in its own fabric pocket and compresses independently, so a partner getting up at five in the morning does not bounce your side of the bed.
Thirteen inches of support
The tallest firm model in the line. The height comes from the extra ComfortFirm layer, not from more soft foam, and it pairs with most adjustable bases. Confirm your base model with the store first.
Free shipping, lower 48 only
Ships direct from Jamison's factory via UPS at no charge anywhere in the contiguous United States or Washington, DC. Not available to Alaska, Hawaii, or United States territories.
Not on a showroom floor
The Apex Pro is an online exclusive. It is not on any Mattress Overstock floor right now, so there is nothing to try in person. Read the firmness notes before you order.
Ten years from Jamison
A 10-year full warranty backs the Apex Pro, and every Sleep Response model comes with a 60-day comfort trial. Warranty, damage, or exchange questions after delivery go to help@mattressoverstock.us.
Eight layers, and where the firm comes from
The InfinityChill Copper Cover is on top, a cool-to-the-touch knit with copper-infused fibers that are naturally antimicrobial. Beneath it, Safe Slumber fire retardant fibers meet the federal open-flame standard with no chemical flame retardant sprays.
The cushion is next. Gel Cooling Foam comes first, gel-infused to help move heat away from the surface. QuiltSoft Foam with gel follows and gives the top of the bed its slight give. Under those sits ComfortVisco memory foam, a thin contouring layer that takes the pressure off your shoulders and hips without letting you sink far.
Then the layer the Elevate Plush does not have. ComfortFirm Foam is a firm transition layer that catches your weight before it reaches the springs, and it is the reason the Apex Pro reads as an 8 while sharing most of its upper layers with a plush sibling. The QuantumEdge individually wrapped coil system sits below it, each coil in its own pocket so it compresses on its own and keeps motion local. HD Base Foam at the bottom keeps the whole thirteen inches square and stable. Jamison's spec sheet shows CertiPUR-US certified foams.
For sleepers who want to be held up, not hugged
Back sleepers The core audience. An 8 keeps your hips and lower back level with your shoulders, and the thin cushion on top means it does not feel like sleeping on the floor.
Stomach sleepers Equally at home. Stomach sleeping needs the hips held high so the lower back does not arch, and the ComfortFirm layer over the coils does that better than any softer model in the line.
Heavier sleepers Firm hybrids hold up under more weight than plush foam beds, and the Apex Pro has both a firm transition foam and a wrapped coil core doing the work.
Couples who both like firm The wrapped coils keep movement on one side, and there is little soft foam on top to wobble. If one of you wants firm and the other wants soft, look at the medium Fusion Elite instead.
Side sleepers Look elsewhere. An 8 will press into your shoulder and hip. The Elevate Plush is the copper-cover hybrid built for you, at a 4 out of 10.
Shoppers who want firm without coils The all-foam Premier Firm is a 7 out of 10 with a LuxFirm high-density foam layer and no springs. It is the closest all-foam alternative in the line.

Frequently asked questions
How firm is the Apex Pro Cushion Firm, really?
Firm. Jamison marks it Extra Firm on its own spec sheet, and on the 10-point scale used here, where 10 is the firmest, it is an 8. The cushion layers on top give a little under your hand, and then the ComfortFirm Foam and the coils stop you. You rest on the bed rather than in it.
Does it sleep cool?
It is one of the cooler-sleeping beds in the line. The InfinityChill Copper Cover is cool to the touch, Gel Cooling Foam and QuiltSoft Foam with gel sit right under it, and because you rest on top of a firm surface, less foam wraps around you to hold heat in the first place.
Is it a hybrid or all-foam?
Hybrid. Five foam layers, including the firm ComfortFirm transition foam, sit over a QuantumEdge individually wrapped coil system, with HD Base Foam underneath. If you would rather have firm without any coils, the Premier Firm is the all-foam sibling at a 7 out of 10.
Can I try the Apex Pro in a showroom?
No. It is an online exclusive and is not on any Mattress Overstock showroom floor right now, so there is nothing to lie down on in person. The showroom Jamison lineup, which includes the Clarion, Easton, Hudson Bay, and Vista, has firm models you can try in a store if you need to feel a firm Jamison first.
Where does it ship, and what does shipping cost?
Shipping is free to the contiguous United States, the 48 states plus Washington, DC. It is not available to Alaska, Hawaii, or United States territories. The mattress ships direct from Jamison's factory via UPS, and tracking is emailed to you as soon as it is on the way.
How does it arrive?
Compressed and roll-packed in a box, shipped via UPS from Jamison's factory, with tracking emailed to you. Thirteen inches of firm foam and coils makes a heavy box, so plan on two people to carry it to the bedroom. Unroll it on your base and give it time to expand to full height.
What is the warranty?
Jamison backs the Apex Pro Cushion Firm with a 10-year full warranty. Warranty or damage questions after delivery go to help@mattressoverstock.us, and the team will open a claim with Jamison for you. Hang on to your order confirmation, because that is what the team will need.
Is there a sleep trial or a return?
Yes. Every Jamison Sleep Response model comes with a 60-day comfort trial, exchange only, with no cash refunds. If the feel is wrong within 60 days of delivery, email help@mattressoverstock.us and the team will set up an exchange for store credit toward a mattress of equal or greater value. You pay any price difference. If you are unsure about an 8, the medium Fusion Elite is still the safer middle ground.
Does it work with an adjustable base?
Typically, yes. Wrapped coils and foam usually flex fine with an adjustable base, and thirteen inches is a common height for one. Confirm your specific base model with the store before ordering, and the team will tell you if the combination is one they have seen work.
How does the Apex Pro compare to the Elevate Plush?
They share the same copper cover, the same gel cushion foams, the same memory foam layer, and the same wrapped coils. The Apex Pro adds ComfortFirm Foam between the memory foam and the coils, which takes it from a 4 to an 8 and adds half an inch of height. Soft sleeper, Elevate. Firm sleeper, Apex Pro.
