Jamison Sleep Response React Cushion Firm Mattress (Online Exclusive)

The firm eight-inch Jamison for the rooms that do not need more bed
The honest verdict: the React Cushion Firm is the mattress you buy for a guest room, a kid's room, a bunk bed, or an RV when you want a real Jamison and not a bare slab of foam from a warehouse club. It is genuinely firm, staged at 8 out of 10 where 10 is the firmest, and Jamison marks it Extra Firm on its own scale. At eight inches it is the shortest and least expensive model in the Sleep Response line, and that is the point. It fits where taller beds will not, it ships free, and Jamison has been handmade in the United States since 1883.
Firm here means you rest on top of the surface. A quilted gel foam layer keeps the first touch from feeling hard, but there is no thick memory foam under it to sink into. If you want plush with memory foam, look at the Ignite Plush. If you want firm over coils, the Aria is a nine-inch firm hybrid staged at 7 out of 10, a step softer.
What is inside
Four layers, top to bottom. The cover is a ComfortKnit MemoryQuilt Foam with Gel quilted comfort layer, so the gel foam is stitched into the quilt itself and sits right under your hand. Beneath it are Safe Slumber fire retardant fibers, which meet the federal open-flame standard without chemical flame retardant sprays. Then a Gel Cooling Foam layer, then the DualCore Support Foam Core that does the actual holding up. There are no coils anywhere in the build, and foam naturally limits motion transfer, which matters when two kids share a room.
Who it fits
Back and stomach sleepers who want a level surface. Kids and teens, who tend to do fine on a firmer bed. Guests who stay a few nights at a time. Bunk beds, trundles, daybeds, and RV bunks, where a low profile keeps the surface below the guard rail and out of the ceiling. Do not buy it as the primary bed for a side sleeper who likes to sink in. A firm surface presses back at the shoulder and hip, and the Ignite Plush or the Ion Plush will suit that sleeper far better.
How buying it online from Mattress Overstock works
This is an online exclusive. The React is not on any Mattress Overstock showroom floor right now, so there is nothing to lie down on in person. If you need to feel a bed before you buy it, the showroom Jamison lineup, including the Clarion, Easton, Hudson Bay, and Vista, lives at the Jamison Bedding collection and you can try those in any of the stores.
Order here and Jamison ships it direct from the factory via UPS, free, anywhere in the contiguous United States, meaning the 48 states plus Washington, DC. Alaska, Hawaii, and the United States territories are not covered. Tracking is emailed once it leaves the plant. It arrives compressed and roll-packed, so it comes through the door as a box, which matters on a bunk ladder or an RV step.
Jamison backs it with a 10-year full warranty. Every Sleep Response model comes with a 60-day comfort trial, exchange only. 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, and there are no cash refunds, so choose the feel on purpose. Warranty or damage questions after delivery go to the same address. Adjustable bases are typically compatible; confirm your base model with the store before ordering. Everyone at Mattress Overstock is paid the same no matter which bed you buy, so the advice you get on the phone is about fit, not commission.
What makes this mattress different
Genuinely firm, 8 out of 10
Staged at 8 out of 10 where 10 is the firmest, and Jamison marks it Extra Firm. You rest on top of the surface, with a quilted gel foam layer taking the hard edge off the first touch.
Eight inches, on purpose
The shortest model in the Sleep Response line. Low enough for bunk beds, trundles, daybeds, and RV bunks, where a taller mattress crowds the guard rail or the ceiling and makes the sheets a fight.
All foam, no coils
A DualCore Support Foam Core does the holding up, with Gel Cooling Foam above it. Foam naturally limits motion transfer, which is useful when two kids share a room or a camper and one of them is a thrasher.
Gel foam quilted into the cover
The ComfortKnit MemoryQuilt Foam with Gel layer is stitched into the quilt, so the gel foam sits right under your hand instead of being buried under a thick pillow top you do not need on a firm bed.
Meets the federal open-flame standard
Safe Slumber fire retardant fibers meet 16 CFR part 1633 with no chemical flame retardant sprays. Jamison's spec sheet shows CertiPUR-US certified foams, which is the claim the store is comfortable repeating.
Ships free, arrives roll-packed
Free UPS shipping direct from Jamison's factory to the contiguous United States. It arrives compressed and roll-packed, so it comes through the door as a box. Tracking is emailed once it leaves the plant.
Factory-direct line, factory pricing
Sleep Response is Jamison's factory-direct line built to ship rather than sit on a showroom floor, and the React is the least expensive model in it. Handmade in the United States by a company building beds since 1883.
Warranty and 60-day comfort trial
Jamison backs the React with a 10-year full warranty, and every Sleep Response model comes with a 60-day comfort trial, exchange only. Warranty, damage, or feel questions after delivery go to help@mattressoverstock.us.
Four layers, firm all the way down
Start at the top. The cover is a ComfortKnit MemoryQuilt Foam with Gel quilted comfort layer. The gel foam is quilted into the cover itself rather than laid loose beneath it, so the cool-feeling material is the first thing your hand touches and it stays put over the years. It softens the first contact without turning a firm bed into a soft one.
Under the quilt sit Safe Slumber fire retardant fibers. They meet the federal open-flame standard, 16 CFR part 1633, using fibers instead of chemical flame retardant sprays.
Next is a Gel Cooling Foam layer. This is the comfort foam proper, the layer that spreads your weight across the surface and helps move heat away from your body instead of holding it against you.
The base is the DualCore Support Foam Core. This is where the firmness comes from and what keeps the surface level under a back or stomach sleeper. There are no coils in the React, so there is nothing to shift or sag inside a bunk frame and nothing to carry movement across the bed. Jamison's spec sheet shows CertiPUR-US certified foams. The whole build comes to eight inches, the shortest in the Sleep Response line, and it arrives compressed and roll-packed.
Best for the rooms where firm and low win
Back sleepers get the level surface a firm bed is meant to give. The DualCore foam holds your hips up in line with your shoulders, and the quilted gel layer keeps the top from feeling like a board. If you have always slept on firm and never understood the appeal of sinking in, this is your kind of bed.
Stomach sleepers are the other natural fit. Sleeping face down on a soft bed lets the hips drop and bends the lower back. An 8 out of 10 keeps you flat, which is what most stomach sleepers actually want once they try it.
Kids and teens are the reason a lot of parents will land here. Growing sleepers generally do well on a firmer surface, and the eight-inch profile fits bunk beds, loft beds, trundles, and daybeds where a tall mattress does not belong. It is priced so that outgrowing it in a few years is not a tragedy.
Guest rooms and second homes want a bed that guests find supportive and that holds up between visits without costing what your own bed cost. The React is that bed. Ship it straight to the cabin or the rental and be done with it.
RV and camper owners get a real mattress in a profile that clears the bunk and the cabinet above it. It arrives roll-packed, so one person can get the box in through the door and up the step.
Side sleepers who like to sink in should look elsewhere. A firm surface presses back at the shoulder and the hip, and no amount of quilting changes that. The Ignite Plush adds a ComfortVisco memory foam layer at 4 out of 10 in a ten-inch build, and the Ion Plush goes to twelve inches with the same plush recipe.

Frequently asked questions
How firm is the React Cushion Firm, really?
Genuinely firm. The store stages it at 8 out of 10, where 10 is the firmest, and Jamison marks it Extra Firm on its own dot scale. You rest on top of the surface rather than sinking into it. The quilted gel foam in the cover softens the first touch, but this is a firm bed, not a medium-firm bed with a firm label.
Does the React sleep cool?
It is built to help. The ComfortKnit MemoryQuilt cover has gel foam quilted into it, and there is a Gel Cooling Foam layer beneath the fire barrier. Gel foams help move surface heat away instead of holding it against you. A firm bed also keeps you on top of the surface, which leaves more of your body exposed to the air than a deep plush bed does.
Is it a hybrid or an all-foam mattress?
All foam. There are no coils in the React. The support comes from the DualCore Support Foam Core, with Gel Cooling Foam and the gel-quilted cover above it. That means no springs to work loose inside a bunk frame, and foam naturally limits motion transfer, which helps when two people or two kids share the bed.
Can I try the React in a Mattress Overstock showroom?
No. The React 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. If trying a bed first matters to you, the showroom Jamison lineup, including the Clarion, Easton, Hudson Bay, and Vista, is at the Jamison Bedding collection, and you can lie on those in any of the stores.
Where does it ship and what does shipping cost?
Shipping is free to the contiguous United States, meaning the 48 states plus Washington, DC. It is not available to Alaska, Hawaii, or the United States territories. Jamison ships it direct from the factory via UPS and tracking is emailed once it leaves the plant. The store does not promise transit days, because UPS does not promise them to the store.
How does it arrive?
Compressed and roll-packed, shipped via UPS from Jamison's factory. It shows up as a box, not a full-size mattress, so one person can get it through the door and into the room. Cut the wrap on the frame or foundation where it will live, let it open up, and it is ready to use. That is a real advantage for a bunk bed or an RV.
What is the warranty?
Jamison backs the React Cushion Firm with a 10-year full warranty. Jamison has been handmade in the United States since 1883, with plants in Ohio, Georgia, Texas, and South Carolina, so the company standing behind the warranty is not a pop-up brand. If a warranty or damage question comes up after delivery, email help@mattressoverstock.us and the team will work through it with Jamison on your behalf.
Is there a sleep trial or a return?
Yes, a 60-day comfort trial, exchange only. 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. There are no cash refunds, so read the sleeper notes on this page before ordering. Nobody at the store is on commission, so the advice you get is about fit.
Does it work with an adjustable base?
Typically, yes. An eight-inch all-foam mattress with no coils bends easily and is usually compatible with adjustable bases. Before you order, confirm your specific base model with the store so the team can check it against Jamison's guidance for this model and you are not guessing on delivery day.
How does the React compare to the Aria?
Both are firm. The React is eight inches, all foam, and staged at 8 out of 10, which makes it the firmer and lower of the two. The Aria is a nine-inch hybrid with a QuantumEdge individually wrapped coil system under the foams, staged at 7 out of 10, so it is a step softer with a bit more bounce. Pick the React for bunks, RVs, and value. Pick the Aria if you want coils.
