The patternThe cool side runs out.
Those pillows cool by absorbing, and anything that absorbs fills up. Flipping just finds another side that's about to warm up too. New pillow, same ending, and not because you picked wrong.

What is it, in one paragraph?⌄
A pillow made entirely of moulded open grid, with nothing inside it. No foam, no gel, nothing sprayed on top. Air passes through the structure instead of soaking into a material that fills up, so the surface under your head does not slowly turn into the warm side.
WHAT IT IS
The pillow is a moulded TPE open grid. That grid is the entire pillow: no foam, no gel, no fill, nothing sprayed on top. Air passes through the structure instead of soaking into a material that fills up.
THE COVER
A removable knit cover comes on it. The weave is open so air can still pass. Zip it off to wash. Most standard pillowcases over it are fine. A thick waterproof encasement can slow the airflow.
SIZE AND HEIGHT
17.3 in across the width (44 cm), 10.6 in front to back (27 cm). Height is 2 to 2.8 in (5 to 7 cm), measured with nothing resting on it: 2.8 in at the highest point of the contour, 2 in at the lowest. One shape, no thick or thin option. Packed weight is 3.1 lb (1.4 kg) including the carton.
WHAT IT FEELS LIKE
Firm and springy rather than sinking. It will look thinner than the pillow you own. That is the design, not a defect. Side sleepers usually need more loft than back sleepers, so put your current pillow next to this one and compare the height at the front edge before you decide. Stomach sleepers often find it too tall. We don't offer a low profile yet.
IN THE BOX
The grid, the knit cover, and any bundle gifts you unlocked at checkout.
Free shipping on every order. We ship within 24 hours on business days. Most orders arrive in about 7 days, sometimes up to 10. Delivery dates are estimates, not guarantees. If a package arrives damaged, email us with your order number and photos and we will replace it once verified.
Try it for 30 nights from delivery. If it isn't right, return it for a full refund to the original payment method. We cover return shipping, and you don't need the original packaging. Contact us with your order number first so we can send return instructions.
The 2-year warranty is separate from the trial. It covers manufacturing defects and structural failure of the grid. A pillow that simply isn't the right loft for you is a trial return, not a warranty claim.
Zip off the cover and machine wash it cold. The grid itself you can rinse under the tap and leave to air dry. Nothing inside it absorbed anything, so there's not much to wash out. Keep it away from high heat.
Flipped the pillow at 1am? Again?
You weren't unlucky. Your last cooling pillow was only cool at first.
You already felt the proof: turning it over at 1am bought you about ninety seconds of relief. Then the other side started warming up too.
The pattern
The structureNothing to warm up.
No gel, no coating, no fill. It's an open grid, so air moves through it instead of heat building up inside it.
Verify itProve it at home. 30 nights.
When it arrives, unzip it and press the grid. Air moves through the holes. That is the whole point: nothing in there holding heat. Sleep on it for 30 nights. Still flipping it? Send it back.

What the first few weeks actually feel like
Honestly, less dramatic than the cooling-pillow ads make it sound. Here's what to expect, and what to watch for.
Nights 1–3
It'll feel different: firmer than foam, springy, it doesn't sink, and it may crinkle a little when you move. That's the part you're getting used to, not the temperature.
Nights 4–10
The strangeness fades. This is the stretch to notice one thing: are you still flipping it?
Week 3 onward
This is the real test, long past the point where your last cooling pillow stopped feeling cool. Nothing here works by absorbing heat, so there's nothing to run out. And if you're still flipping it, send it back.
Latticore Pillow vs. the usual options
What each one actually is, and what that means at 3am.
| Latticore | Memory Foam | Down | |
|---|---|---|---|
| Cools by structure, not a coating | Yes | No | No |
| Nothing inside that absorbs heat | Yes | No | No |
| Same height at 4am as at 11pm | Yes | No | No |
| Softens as your body warms it | No | Yes | No |
| Rinses under a tap | Yes | No | No |
A solid pillow can only hold so much.This one just breathes.
No Gel
Unzip the cover. The grid in that photo is the entire pillow.
No Coating
Nothing was sprayed on it, so there is no finish that wears off on a schedule.
No Cool Side
Both sides are the same grid, so the 1am flip has nothing left to fix.
Rinses Under The Tap
Cover off, grid under the tap, air dry. Nothing inside it absorbed anything, so there is nothing much to wash out.
Tried everything short of sleeping on a tile floor
“Previous list was Tempur cooling gel, Amazon ice-silk cover, a purple-looking dupe that smelled like chemicals. This one actually lets air through, push the grid and you feel it. Minus one star because it's louder than I expected when you adjust, and my husband asked what I was rustling on. Four months in. Got through August without the old sheet-flip routine.”
Fine, not life-changing
“Cooling is better than memory foam, worse than I hoped from the ads. The grid works, air actually moves. Took almost three weeks to stop noticing the texture. Partner hates the sound. I keep it because I sleep a bit better. Not sure it's worth full price if you're on a budget. Three stars because I'm still on the fence, not because it's bad.”
Looked like gimmick padding at first
“Had the gel pillow from the mattress store, the one with the cool-touch cover that went warm by midnight, and a shredded foam one I kept refilling. Expected another letdown. First two nights felt weird, corners stick up a bit and it makes a faint crinkle when I roll. Almost sent it back. Week three I realized I hadn't flipped it around 1am in days. Still not magic. Still warm on brutal August nights. But I don't wake up with a damp head anymore.”

Return stories
These are the reasons people gave us for sending it back, so you can skip the 30 nights if one of them is you.
The rustle woke my husband
I was fine with it. My husband didn't like it. Sent it back after like 10 nights or so.
Too tall for stomach sleeping
I always sleep on my stomach and it sits too high for that. My neck was sore by morning. Sent it back.
Never got used to the feel
Wanted something very soft. This wasn't exactly like I hoped. Not terrible but not for me.
FAQ
Straight answers
The questions we'd ask before spending again, including the ones that don't have a marketing-friendly answer.
How is this different from the cooling pillows I've already bought?
If your shelf looks like this: gel layer, cool-touch cover, ice-silk, shredded foam with a cooling pad. Same ending, different box.
Those all work the same way: something on or in the pillow pulls heat from your head until it can't anymore. Then you're flipping it, hunting for a side that hasn't turned into a pool of heat yet.
This is an open moulded grid with nothing inside it. Air moves through the structure instead of heat building up in a material. Different object, not a stronger version of the one you gave up on.
Why is this $170 when my last one was $40?
Because it isn't cut foam with something sprayed on top. Moulding an open grid costs more to make than slicing foam, and there's no coating to wear off on a schedule.
If you've already tried three pillows that didn't work, you've likely spent more than this. If this turns out to be the fourth, it goes back inside 30 nights.
Does it stay cool all night, or just at first?
You already know the first-twenty-minutes story: cold, then the same warm, damp head you were trying to escape.
That happens because gel and coatings fill up. There's nowhere left for heat to go except back to you. There's nothing here that saturates, because nothing absorbs.
We're not attaching an hour-by-hour temperature chart. The thing that ran out on your last pillow doesn't exist here.
Can you point to proof it works?
We didn't commission a test. Neither have others in this category, as far as we can tell. There's no lab report or degrees figure to paste here.
What you can check yourself: unzip the cover, hold the grid up to a window, and the light passes through. Push it and you feel air move.
Read the three-star reviews on this page as well, not just the five-stars. Then run the 30-night trial in your room. That's the only test that matters for you.
Is there a cool side to flip to?
The flip is the symptom: turning the pillow over at 1am because one face warmed under your head and the other still feels briefly cold.
There's no cool face versus warm face here. Air moves through the whole structure, so you're not constantly hunting for the side that hasn't saturated yet.
What does it feel like?
Firm and springy rather than sinking, more supportive than plush. Most people say it feels strange for two or three nights, then normal. If you've only slept on memory foam, expect an adjustment.
Height: one contour profile, no thick/thin menu. Side sleepers usually need more loft than back sleepers. Stack your current pillow next to this one and compare.
Stomach sleepers often find it too tall. We don't offer a low profile yet.
Does it make noise?
A little, when you move. It's a structure, not a solid block.
Most people stop noticing. Some don't.
I'm just a hot sleeper. Will anything work?
Maybe not. This won't cool a warm room, and it won't change how your body runs.
It removes one specific thing, which is heat building up in the pillow under your head. That's the 30-night trial's job to settle, not ours.
Will my pillowcase or a waterproof protector block the airflow?
A thick waterproof encasement can slow airflow. People ask that on every grid-pillow thread for a reason.
The included knit cover is an open weave meant to let air pass, not seal it in. Most standard pillowcases over it are fine.
If you wrap everything in crinkly plastic protectors, expect the same dulling you'd get on any vented pillow.
How do I clean it?
If your gel pillow needed fifteen to thirty minutes to peel the cover off and chase stuffing back inside, this isn't that.
Zip off the knit cover and machine wash cold. Rinse the grid under the tap and air dry.
Nothing inside absorbed sweat or oils, so there's not much to wash out of the structure itself.
What if it doesn't work for me?
Try it for 30 nights. If it's not right, return it for a full refund.
We cover return shipping, you don't need the original packaging, and the 2-year warranty is separate. Manufacturing defects are on us either way.
Does it flatten over time?
The real worry is whether it ends up like foam, softer and trapping heat by morning. It's moulded structure, not fill, so body heat doesn't collapse it the way shredded or memory foam does.
We've been selling it for eight months. That's the honest horizon we can speak to today.
The 2-year warranty covers structural failure if the grid gives out long before that.
Does it smell out of the box?
Most TPE products have a light new-material smell for a day or two, not the sharp chemical smell some foam and gel pillows arrive with.
Worth airing it near a window before the first night if you're sensitive. It fades quickly with normal use.
Are these reviews real?
Reviews on this page are tied to verified purchases. We don't pay for five-star-only posts, and we leave up mixed and critical ones.
Patricia W.'s three-star take is still here on purpose. If a quote only lives in an ad, apply the same skepticism you would anywhere else.
