The medium hybrid that settles the argument
The honest verdict: the Fusion Elite is the bed to buy when two people cannot agree, or when you change position all night and need a surface that keeps up. Jamison rates it a 6 out of 10, where 10 is the firmest, which lands it in the middle. Soft enough that a side sleeper's shoulder settles in, firm enough that a back sleeper does not sink. It is also the fourteen-inch flagship of the Sleep Response line, and the only model with both copper-infused memory foam and a latex layer.
Two sibling hybrids share the same copper cover and coil system. The Elevate Plush is a 4 for people who want to sink, and the Apex Pro Cushion Firm is an 8 for people who want to rest on top. The Fusion Elite is the one in between, and the extra inch over the Apex Pro comes from the two comfort layers neither sibling has.
What is inside, and why the latex matters
The cover is InfinityChill Copper, cool to the touch with copper-infused fibers that are naturally antimicrobial. Safe Slumber fire retardant fibers under it meet the federal open-flame standard without chemical sprays. Then Gel Cooling Foam and QuiltSoft Foam with gel, the same soft opening found on the Elevate and the Apex Pro. Below that come the two layers that set this bed apart. CopperFusion Memory Foam is memory foam with copper infused through it, so the contouring layer carries the same cooling and antimicrobial idea as the cover. Under it sits an AeroSpring Latex comfort layer. Latex is resilient and breathable, and it pushes back instead of holding the shape you leave in it, which is why the Fusion Elite feels quicker to move on than a memory foam bed and why it does not contour as deeply as the Elevate. ComfortFirm Foam bridges to the QuantumEdge individually wrapped coils, and HD Base Foam finishes the build.
Who it fits
Combination sleepers first. If you go to sleep on your side and wake up on your back, the latex layer lets you roll without fighting a memory foam impression. Couples with different preferences are the second group, because a 6 is the number most pairs can both live with. Back sleepers get level support from the ComfortFirm layer and the coils, and side sleepers get enough give at the shoulder from the memory foam and latex together. If you know you want deep, slow contouring, buy the Elevate. If you know you want a plank, buy the Apex Pro. The Fusion Elite is for everyone who is not sure, or who has to share.
How buying it online from Mattress Overstock works
The Fusion Elite is an online exclusive, and it is not on any Mattress Overstock showroom floor right now, so there is nothing to lie down on in person. Read the layer notes above before you order. The showroom Jamison lineup at Jamison Bedding is what you can try in a Kentucky store. Everyone at Mattress Overstock is paid the same no matter which bed you buy, so a call to the store about this bed gets you a straight answer.
Shipping is free to the contiguous United States, meaning 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, 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. The Fusion Elite is the top of it.
What makes this mattress different
Medium feel, rated 6
Jamison rates the Fusion Elite a 6 on a scale where 10 is the firmest. It is the middle of the copper-cover hybrids, soft enough for a side sleeper and firm enough for a back sleeper.
Copper in cover and foam
The InfinityChill Copper Cover is cool to the touch, and CopperFusion Memory Foam below it carries copper through the contouring layer as well. Both use copper-infused material that is naturally antimicrobial.
Latex that pushes back
An AeroSpring Latex comfort layer sits under the memory foam. Latex is resilient and breathable and springs back when you move, so changing position does not mean climbing out of an impression.
Wrapped coils under it all
A QuantumEdge individually wrapped coil system carries the load, each coil in its own fabric pocket. Movement on one side stays there, and the coils keep the bed steady under two people.
Fourteen inches, the tallest hybrid
The deepest build in the Sleep Response line. Check that your fitted sheets have deep pockets, and confirm your adjustable base model with the store before ordering.
Free shipping to the lower 48
Ships direct from Jamison's factory via UPS, compressed and roll-packed, with tracking emailed to you. No shipping charge anywhere in the contiguous United States or Washington, DC.
Online exclusive, read before buying
The Fusion Elite is not on any Mattress Overstock floor right now, so there is nothing to try in person. The layer and sleeper notes on this page are there to do that job for you.
Ten-year full warranty
Jamison backs the Fusion Elite with a 10-year full warranty, and every Sleep Response model comes with a 60-day comfort trial. Warranty, damage, or exchange questions after delivery go to help@mattressoverstock.us.
Nine layers, and the two that matter most
The InfinityChill Copper Cover is on top, 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 with no chemical flame retardant sprays.
Gel Cooling Foam comes next, then QuiltSoft Foam with gel. These two are the soft opening every copper-cover hybrid in the line shares, and they are what your hand feels first. Below them are the two layers only the Fusion Elite has. CopperFusion Memory Foam is memory foam infused with copper, so the layer that contours to your shoulders and hips carries the same cooling and antimicrobial idea as the cover. Under it sits the AeroSpring Latex comfort layer. Latex is resilient and breathable, and it springs back instead of holding your shape, which keeps the bed from contouring as deeply as the Elevate and makes it easier to change position.
ComfortFirm Foam sits under the latex as a firm transition layer, then the QuantumEdge individually wrapped coil system takes the load, each coil compressing on its own. HD Base Foam at the bottom keeps all fourteen inches square. Jamison's spec sheet shows CertiPUR-US certified foams.
For the undecided, the restless, and the couple who disagree
Combination sleepers The best match in the line. The AeroSpring latex springs back when you roll, so moving from your side to your back does not mean waiting for memory foam to let go of you.
Couples with different preferences A 6 out of 10 is the number most pairs can both live with. The wrapped coils keep one side's movement from reaching the other, and fourteen inches of build stays steady under two people.
Back sleepers Level support from the ComfortFirm layer and the coils, with enough memory foam and latex above them that your lower back is cushioned rather than bridged.
Side sleepers Enough give at the shoulder and hip for most side sleepers. If you want to sink deep and slow, the Elevate Plush at a 4 does that better.
Hot sleepers Copper in the cover, copper in the memory foam, gel in two upper foams, and a breathable latex layer. This is the most cooling-focused build in the Sleep Response line.
Firm sleepers Look elsewhere. A 6 has real give at the surface. The Apex Pro Cushion Firm at an 8 is the copper-cover hybrid that holds you flat.

Frequently asked questions
How firm is the Fusion Elite, really?
Medium. Jamison rates it a 6 out of 10, where 10 is the firmest. Your shoulder and hip settle into the memory foam and latex, but the ComfortFirm layer and the coils stop you well before it feels soft. Think of it as the bed most people land on when a firm one feels hard and a plush one feels like too much.
Does it sleep cool?
It is the most cooling-focused build in the line. Copper is in the InfinityChill cover and in the CopperFusion Memory Foam, gel is in the two foams above that, and the AeroSpring latex layer is breathable by nature. No mattress is cold, but this one stacks more cooling layers than any sibling.
Is it a hybrid or all-foam?
Hybrid. Six comfort and transition layers, including copper memory foam and latex, sit over a QuantumEdge individually wrapped coil system, with HD Base Foam at the bottom. There is no all-foam sibling at a medium feel, so if you want medium in this line, the Fusion Elite is it.
Can I try the Fusion Elite 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, is what you can try in a store. Reach out to the store with questions before you order.
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 leaves the plant.
How does it arrive?
Compressed and roll-packed in a box, shipped via UPS from Jamison's factory, with tracking emailed to you. Fourteen inches of foam, latex, and coils is a heavy roll, so have a second person on hand to move the box. Unroll it on your base and give it time to reach its full height.
What is the warranty?
Jamison backs the Fusion Elite 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 on your behalf. Keep your order confirmation handy, since the team will use it for that.
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 of your feel, a medium like this is still the safer first pick.
Does it work with an adjustable base?
Typically, yes. Wrapped coils, foam, and latex all flex, and the Fusion Elite is built like most hybrids that pair with adjustable bases. Fourteen inches is on the tall side, so confirm your specific base model with the store before ordering and the team will check the fit.
How does the Fusion Elite compare to the Apex Pro Cushion Firm?
Same copper cover, same gel foams, same ComfortFirm layer, same wrapped coils. The Fusion Elite swaps the Apex Pro's plain memory foam for CopperFusion memory foam and adds an AeroSpring latex layer, which is where the extra inch and the softer 6 out of 10 come from. Want firm, Apex Pro. Want medium with bounce, Fusion Elite.
