The CopperFlex is a firm, all-foam mattress that stays under $1,000 for a queen while carrying CertiPUR-US and GREENGUARD Gold certification and publishing every layer. Its edge support is the standout. Hot sleepers and heavier back or stomach sleepers should look elsewhere.
- 12 inches tall, one firmness, six layers, all published by Brooklyn Bedding.
- Labelled medium firm, but testing put it between 7 and 8 out of 10.
- Queen listed at $865 at the time of review, with a 365-night trial and limited lifetime warranty.
- Rebuilt in January 2026, so many reviews online describe the older, taller version.

When people picture a cheap mattress, they think thin, too firm, and a cover that frays in a few months. The bigger risk at the low end is one you can't feel at all: the materials inside. Cheaper foams and chemicals that better brands stopped using years ago don't show up in how a bed feels on day one.
So our test for a good-value mattress is three things together: the price, what the foam is certified for, and whether the brand tells you exactly what's inside, layer by layer. The Brooklyn Bedding CopperFlex passes all three at well under $1,000.
Quick verdict
If you want a firm mattress and have been priced out of the ones that feel well made, the CopperFlex is the one to look at. It works for side, back and stomach sleepers, has excellent edges for an all-foam bed, and is certified inside and out. Skip it if you sleep hot, or if you're over about 230 lb and sleep on your back or stomach. Brooklyn Bedding's hybrid version suits you better.
What we mean by affordable
The working line in the industry is under $1,000 for a queen. The second check is certification. CertiPUR-US means the foams have been tested for things like formaldehyde, heavy metals and certain flame retardants. GREENGUARD Gold means the finished mattress has been tested to keep what it gives off into the air below a set limit. A bed under $1,000 that carries both isn't the bed anyone is warning you about. The third check is simple: if a brand won't show you what's inside the mattress, there's usually a reason.
On firmness, we use a 1–10 scale where 1 is sinking into a cloud and 10 is lying on a plank. Around 6 is where most people are comfortable.
What's inside: six layers, all published
The CopperFlex is 12 inches tall, comes in one firmness, and Brooklyn Bedding lists every layer. From the top:
| Layer | Thickness | What it does |
|---|---|---|
| Quilt foam | 1 in | Surface softness in the cover |
| Copper-infused memory foam | 1.5 in | Pressure relief at the surface |
| Comfort foam | 0.75 in | Firms up quickly under the memory foam |
| Transition foam | 3 in | Stops you sinking through to the base |
| Zoned lumbar support | 0.75 in | Extra support under the lower back |
| High-density support foam | 5 in | Holds up the whole mattress |
Note how little memory foam there is: an inch and a half, then firmer foam. That one fact explains most of how this bed behaves. Brooklyn Bedding says the copper helps regulate temperature and stop bacteria building up. The mattress is designed and assembled in Arizona and carries CertiPUR-US on the foams and GREENGUARD Gold on the whole mattress.
Watch out for older reviews: Brooklyn Bedding rebuilt this mattress in January 2026. The version most reviews tested was taller with a thicker copper layer. Everything here describes the current 12-inch, six-layer build.
Firmness and feel
It's firmer than the label suggests. Brooklyn Bedding calls it medium firm, but testing reads it between 7 and 8. Most memory-foam beds give you a deep layer to sink into. This one gives you a thin layer sitting on firmer foam, so the top gives under your shoulders and hips, but you stay on top of the bed rather than down in it. When you roll over, the foam comes back up with you instead of holding on.
That combination is why it works across positions: side sleepers get pressure relief at the surface, and back and stomach sleepers get a base that doesn't let their hips drop.
Edge support, motion and temperature
Edge support is the strongest thing about this bed. Sitting right on the edge, testing measured about 2 inches of sink for a lighter person and a little over 3 for a heavier one, which is excellent for an all-foam mattress. Lying near the edge, it holds you, so you get the full width of the bed and can sit on the side to put your shoes on without sliding off.
Movement doesn't travel much across it either, so if you get up in the night your partner probably won't feel it, which makes it a good pick for couples.
On temperature, the copper-infused foam is designed to pull heat away, and because you rest on top rather than sinking in, less foam wraps around you. It won't feel like an active cooling system, but it sleeps temperature neutral and avoids the stuffy feel of traditional memory foam.
Price, trial and warranty
A queen listed at $865 at the time of review, and Brooklyn Bedding runs sales through the year, so check the current price. For that you get a mattress assembled in Arizona, certified foams, GREENGUARD Gold certification, every layer published, a 365-night trial and a limited lifetime warranty. It also arrived with basically no smell, which is unusual for a foam bed, so you can sleep on it the first night.
Who should skip it
- Hot sleepers. It runs neutral rather than cool. If heat is why you're replacing your mattress, this isn't the fit.
- Heavier back and stomach sleepers. If you're over about 230 lb and sleep on your back or stomach, it may not hold you up. The bed is rated to 950 lb total, but that's about damage, not comfort. Brooklyn Bedding makes the same bed as a hybrid with springs under the foam, and that's the one for you.
- Anyone who wants a soft bed. It's firm. If you're unsure, the 365-night trial gives you time to find out.
