This pillow has a cut-out area for your arms. Here's how it's built
Most pillows are rectangles. The Derila Ergo has a curved center, raised edges and a cut-out area for your arms. Here is what the seller says about it, and what to check before you order.
If you sleep on your side with one arm tucked under the pillow, or you turn from your side to your back and over again, you know the problem with a plain rectangle. It bunches up, your arm has nowhere to go, and you end up folding the pillow in half.
Contoured memory foam pillows take a different approach: the shape is fixed, and it is cut to fit around your head, neck and arms. The Derila Ergo is one of them. Its outline looks a little like a butterfly.

How the seller says to use it
The user guide gives a different position for each kind of sleeper:
On your side
Place the pillow so the curve at the front rests against the side of your neck.
On your back
Rest the back of your neck on the front curve and let your head settle toward the center.
On your stomach
Lie a little higher up on the pillow, rest your cheek in the central curve and use the cut-out for your arm.
What to know before it arrives
- It arrives flat. The pillow ships vacuum-packed. The seller says to leave it for 6 to 8 hours after you open it so it can reach its full size.
- Check the size. The seller lists one standard size: 21.2 × 14.1 × 4.7 in (54 × 36 × 12 cm). It doesn't say where the 4.7 in is measured, and a contoured pillow is lower in the middle than at the edges, so compare it with the pillow you sleep on now.
- Memory foam feels different. Foam pillows are firmer than down or fiberfill, and foam in general feels firmer in a cold room. If you have never used one, keep in mind that the seller's terms accept returns of unused pillows only.
The price: compare the bundles
The seller sells the pillow on its own and in sets of two, three and four. Prices change and can differ by country and by offer, so we don't quote them here. Compare the per-pillow price for each option, check that the cart shows only what you chose, then look at the total with shipping before you pay.

Questions people ask
Is it only for side sleepers?
No. The seller describes it as a pillow for side, back and stomach sleepers, and its user guide shows how to place it for each. Comfort is personal, though, so read the returns terms before you order.
Why does it arrive flat?
It ships vacuum-packed to keep the package small. The seller says to take it out and leave it for 6 to 8 hours so the foam can return to its full size.
Can I wash it?
The cover zips off and is machine washable in warm water, according to the seller's user guide. The guide covers the cover only, so check the care label before you clean the foam itself.
Can I return it?
The seller lists a 60-day return policy, but read the conditions. Its terms say it accepts only goods that have not been used and that come back in the original, undamaged packaging, so a pillow you have slept on may not qualify. In the first 14 days you get back the purchase price and the standard shipping fee; from day 15 to day 60, the purchase price only. You must contact the seller for a return form before you send anything, you pay the return shipping to the address on that form, and you should use a tracked service, because returns without a tracking number may be refused. If you think you might return it, ask the seller what counts as unused before you open the vacuum pack. Read the full policy and terms on the seller's site.
Is this a medical product?
No. It is a regular pillow. This page covers its shape, size and care only; it makes no health claims and is not medical advice.
If a flat rectangle never quite sits right for the way you sleep, a contoured pillow is worth a look. Check the height, the returns terms and the bundle prices first.
