Back support wings
The raised wings along the back edge help hold your head in place and assist neck alignment, so you are less likely to roll off the supportive part of the pillow during the night.
The Derila Ergo is a contoured memory foam pillow with a butterfly shape, support wings and an arm cut-out. It is made to keep your head, neck and shoulders lined up whether you sleep on your side, back or stomach. This guide covers how it works, what you get, what it costs and how returns work, so you can decide with the facts in front of you.
The Derila Ergo Pillow is an ergonomic memory foam pillow sold by the Derila Ergo brand, which is operated by EcomLT LLC, a direct-to-consumer retail company based in Franklin, Tennessee. The company says it develops household products and ships to more than 90 countries. Derila is best known for its contoured pillows, and the Ergo is its butterfly-shaped model.
Most pillows are a soft rectangle. You push them into shape before bed, and by 3 a.m. they have flattened or bunched up, leaving your head tilted at an angle your neck was never meant to hold for hours. The Derila Ergo takes a different approach. Instead of one flat surface, it has several shaped zones: raised wings at the front and back, a dip in the middle for your head, an arch for your shoulder and a cut-out where your arm can rest.
The idea is simple. If the pillow already has the right shape, your head and neck can settle into a neutral position and stay there, rather than sliding around all night. The memory foam softens slightly with body heat and moulds to you, then slowly returns to shape when you move.
The pillow measures 54 x 36 x 12 cm (21.2 x 14.1 x 4.7 inches) and comes with a zippered, removable cover. It ships vacuum-packed, so it arrives compressed and needs a few hours to expand to its full size.
Five support zones work together. Each one handles a different part of the head, neck, shoulder and arm, which is why the pillow looks so unusual next to a standard one.
The raised wings along the back edge help hold your head in place and assist neck alignment, so you are less likely to roll off the supportive part of the pillow during the night.
The front wings fill the gap under your neck. Derila says this helps spinal alignment and lets the neck muscles relax, and it also lists better jaw alignment as a design goal.
An arched section gives your shoulder somewhere to go when you lie on your side, instead of jamming it against a solid block of pillow. Less pressure here means less tension carried into the morning.
The dip in the middle cradles the back of your head. It doubles as a chin rest for stomach sleepers and leaves a small gap for earbuds or headphones. Derila also credits it with helping the pillow keep its shape.
The cut-out at the base lets you tuck an arm under the pillow without lifting your head out of position. This is aimed at the common "numb arm" problem many side sleepers know well.
Underneath is memory foam that contours to you. On top is a breathable cover that Derila says disperses heat and manages moisture, with hypoallergenic materials to keep the sleep surface clean.
When a pillow is too flat, too high or sinks as the night goes on, your neck spends hours bent sideways or tipped forward. That position strains muscles that should be resting. It is a common reason people wake up stiff even though they did nothing strenuous the day before. Keeping the neck in a neutral line with the rest of the spine takes that strain off.
The image here shows the idea Derila builds its design around. On a worn-out pillow, the head drops and the spine curves. On the Ergo, the shaped zones keep the head level with the upper back.
To be clear, a pillow is a comfort product, not a treatment. If you have ongoing neck pain, numbness or pain after an injury, MedlinePlus lists the many causes of neck problems, and a doctor or physical therapist is the right person to look at it. For everyday stiffness from a poor sleeping position, though, better support is a sensible place to start.
Derila points out that snoring often starts with poor sleeping posture that narrows the airway, and says the Ergo's support wings and neck alignment help keep the airway clear. That is a reasonable idea. Positional snoring often gets worse when the head tips back or forward, so a pillow that holds a steadier position may help some people snore less.
What a pillow cannot do is fix every kind of snoring. MedlinePlus notes that snoring has several causes, including nasal blockage, alcohol and sleep apnea. If your partner hears loud snoring with pauses, choking or gasping, or you feel exhausted during the day, read the NIH's guide to sleep apnea symptoms and talk to your doctor. That condition needs proper diagnosis and treatment.
Derila's user guide gives a simple setup for each position. Here is what it says, in plain terms.
Rest the front curve against the side of your neck. Your shoulder drops into the arch and your arm can slide into the cut-out.
Fit the curve of your neck against the pillow's front curve and let the back of your head rest toward the centre.
Lie slightly higher on the pillow, let your cheek settle into the central curve, and use the arm cut-out if it feels natural.
Make sure the pillow is the right way up and facing you. The curves are meant to keep you aligned as you turn.
Give yourself a few nights. Derila says most people notice a difference early, but that it can take around 5 to 7 nights for your body to adjust to a new sleeping posture.
The Derila Ergo is a physical product, so there is nothing to download or log into. Each pillow you order arrives as follows:
Derila uses vacuum packing to make the package smaller, which it says is for environmental reasons. Here is the process from its user guide:
Pull along the dotted line or cut it carefully with scissors, without cutting the inner bag.
Take out the second vacuum-sealed bag that protects the pillow itself.
Cut along the inner bag's dotted line, taking care not to nick the foam, and lift the pillow out.
Leave it for 6 to 8 hours. The foam slowly takes on its final shape and size.
Derila also sells optional extras on its own store, such as a spare pillowcase, an anti-dust cover and a thermo cover. They are separate purchases and are not needed to use the pillow.
Because this is a pillow and not a digital course, there are no bonus e-books or videos. The extra value comes from the bundle pricing, especially the free fourth pillow in the Family Pack.
Four pillows for $149.96
Buy three and the fourth is included at no extra charge. That works out to about $37.49 per pillow, the lowest per-pillow price on the order page.
Two pillows for $99.98
About $49.99 each. Derila suggests two so you can keep one at home and one for travel, or have a backup while a cover is in the wash.
Included with every pack
Each package shows a 60-day guarantee on the order page, which gives you time to sleep on it for weeks before deciding. Read the details in the returns section below.
The Ergo makes the most sense for people whose current pillow is part of the problem. These are the groups most likely to get something out of it.
If you love a very soft, squashy pillow you can fold in half, a shaped memory foam pillow will feel very different, and some people never get used to it. If you have a diagnosed neck or spine condition, ask your doctor or physical therapist which pillow height and shape suit you. And if loud snoring is the main issue, get checked for sleep apnea before relying on any pillow.

The order page notes that local taxes may apply. Shipping and handling charges, if any, are shown at checkout before you confirm. Prices can change at any time, so the figure on the order page is the one that counts.
If you only want to try the shape for yourself, the single pillow is the simplest choice and still comes with the 60-day window. If you share a bed, the two-pack makes sense, because a mismatched pillow next to you tends to get "borrowed". If you are setting up several beds or want a spare for travel, the Family Pack gives you four pillows for roughly what three would cost at the two-pack rate.
Every package on the order page is listed with a 60-day guarantee, and the brand's FAQ calls it a 60-night trial. In practice it works through Derila's written return policy, so it is worth knowing the details before you order.
The fine print: return shipping is paid by you and is not refunded. If you return within 14 days of delivery, Derila refunds the product price and the original delivery fee. Between day 14 and day 60, you get the product price back, but not the original delivery fee. Items that are not defective should go back in their original, undamaged packaging, so keep the box. For a defective pillow, contact support before sending anything.
This policy covers pillows bought through Derila's own checkout. If you buy a Derila pillow from another seller, that seller's return rules apply instead.
The pillow ships from Derila's fulfilment centres in a compact vacuum-sealed parcel. Here is what the shipping policy says.
Orders are usually processed within one to two business days. Derila notes this can take longer during holidays and big promotions.
That is the vendor's estimated delivery time for US orders, and the same estimate applies to the UK. Other countries are listed in its shipping policy, mostly between 8 and 18 business days.
You can follow your parcel on Derila's tracking page using your order number, tracking number or email address. Updates come from the carrier.
A pillow is low-risk, but a few points are worth keeping in mind.
At the time of writing the vendor lists one pillow at $59.99, two pillows at $99.98 and the Family Pack (3 + 1 free, four pillows) at $149.96. Local taxes may apply and prices can change, so check the order page for today's figures.
It is designed with side sleepers in mind. The vendor's guide says to rest the front curve against the side of your neck, and the shoulder arch and arm-support cut-out leave room for your shoulder and lower arm.
No pillow can promise that. The vendor says better head and neck position can help keep the airway open, which may make positional snoring quieter for some people. Loud snoring with gasping or daytime sleepiness can be a sign of sleep apnea and should be checked by a doctor.
The vendor offers a 60-day return policy from the day you receive the pillow. You contact support for a return authorization form, send the item back with tracking, and the refund is issued within 14 days of the return being received. Return shipping is paid by the buyer.
Orders are usually processed in 1 to 2 business days. The vendor estimates 8 to 12 business days for delivery to the United States and the United Kingdom, with other countries listed separately in its shipping policy.
The standard size is 54 x 36 x 12 cm, which is 21.2 x 14.1 x 4.7 inches.
It ships vacuum-packed to keep the parcel small. After unpacking, the vendor says to leave it for 6 to 8 hours so the memory foam can return to its full shape.
The zippered cover comes off and is machine washable in warm water, according to the vendor's user guide. The foam core itself should not go in the washing machine.
The order buttons on this page go to the Derila Ergo order page, where the 60-day return policy applies. Pillows bought from other sellers fall under that seller's own return terms.
Derila Ergo is a brand operated by EcomLT LLC, a direct-to-consumer retail company based in Franklin, Tennessee, which says it delivers to more than 90 countries.
If your current pillow goes flat, leaves your neck stiff or crushes your shoulder when you sleep on your side, the Derila Ergo is a well-thought-out alternative.
Its strength is the design. Five shaped zones, an arm cut-out and a cooling cover tackle the specific things that make ordinary pillows uncomfortable. Pricing is clear, from $59.99 for one pillow down to about $37.49 each in the Family Pack. The 60-day return window gives you time to judge it properly.
Keep your expectations realistic. It is a comfort product, not a medical device. The shape takes a few nights to get used to, and if you return it you pay the return postage. If those trade-offs sound fair, it is an easy pillow to try.
