Derila vs Sutera (2026): Two One-Size Contour Pillows, One Publishes Its Height
Quick answer: these are close cousins — both one-size contoured memory foam, both CertiPUR-US, both making cooling claims, both sold direct. Three real differences. Derila publishes its height (4.7 inches); Sutera does not publish one at all. Sutera can be rotated 180° for a higher or lower side, which helps if you are between sizes. And Derila’s returns are a clear 60 nights, while Sutera’s own product page states both a 30-day guarantee and a 90-day guarantee in different places. On price, Sutera is $65.46 for one and Derila $59.99, with both getting cheaper in multipacks. Buy Derila if you want a known height and a return window you can quote back; buy Sutera if you are unsure of your loft and want the rotate-to-adjust option. If you do not know the height you need, neither is a safe purchase yet — get that number first.
Work out your loft before you pick either
Both pillows come in one height. Whether either fits you is decided by your shoulder width, sleeping position and mattress firmness — not by the brand. It takes about thirty seconds and costs nothing.
The Specs, Side by Side
Everything below is taken from each manufacturer’s own product page, checked on 23 September 2026. Where a figure is missing, that is because the brand does not publish it — which is itself a finding, and one we measured across 32 pillows. (Short on time?

The Difference That Actually Decides It
Height. Not brand, not foam grade, not the cooling claim. A contour pillow works when it fills the gap between your neck and the mattress, and fails when it does not, and both of these come in exactly one size.
Derila states 4.7 inches. That is a number you can compare against the loft you actually need. Sutera publishes no height at all, so the only way to find out whether it fits you is to buy it and sleep on it. When we went through 32 pillows, 16 of them published a loft figure and 16 did not, so Sutera is in ordinary company here — but it still leaves you guessing.
What Sutera offers instead is a rotate-to-choose design: turn it 180 degrees and you get a higher or lower side. If you are genuinely unsure of your number, that hedge has value. It is a different way of solving the same problem: Derila tells you the height, Sutera gives you two to try.
Either way, start with your own number. Roughly 7–10 cm suits back sleeping and 10–14 cm side sleeping, adjusted for shoulder width and how far your shoulder sinks into the mattress.
The Returns Wrinkle
Return windows matter more with contour pillows than with ordinary ones, because a new contour reliably feels wrong for the first week or so while your neck adapts. A 30-day window is enough to get through that; it is not generous.
Derila’s 60 nights is stated plainly and consistently. Sutera’s product page states a “30-Day Sleep Guarantee” in one place and a “90 day guarantee, full refund” in another. We are not suggesting anyone is being misled — but two numbers on one page means you should get the answer in writing from their support before you order, especially if you are buying the multipack.
Price, Honestly
Single pillow to single pillow, Derila is cheaper: $59.99 against $65.46. Buy two and the gap widens, because Derila’s two-pack works out at $49.99 each against Sutera’s $58.19. Buy four and Derila drops to $37.49 each, though that is only a saving if you genuinely want four pillows.
Neither is expensive next to a Tempur-Pedic at roughly $179, which is the comparison we make in Derila vs Tempur-Pedic.
Which One Should You Buy?
- Buy the Derila if your calculated loft is near 9–12 cm, you want a published height rather than a surprise, and you want a return window that is stated once and clearly. It is also the one I have used myself, and the full review is blunt about who it does not suit.
- Buy the Sutera if you are between heights and the rotating higher and lower sides sound like the hedge you want, or if you specifically want a stated medium-firm rating.
- Buy neither yet if your number is well outside 9–13 cm. A one-size contour will not work for you, and an adjustable-fill pillow you can add or remove stuffing from will. That is not a sales answer, but it is the right one.
Our pick of the two: Derila Ergo
A published 4.7 in loft, a clear 60-night money-back window, and $59.99 for one. Check your loft first — if your number is far from 9–12 cm, neither of these is the right pillow.

Where we stand: we earn a commission if you buy the Derila through our link. We earn nothing from Sutera, and we have no affiliate relationship with them. That is exactly why the specification table above comes from their own page rather than ours, and why the recommendation above has a “buy neither” option in it.
Frequently Asked Questions
Is Derila or Sutera better for side sleepers?
Both are sold as suitable for side sleeping, and both come in one size. Derila’s published edge height of 4.7 inches (about 12 cm) sits in the usual side-sleeping range of 10–14 cm. Sutera publishes no height, but its higher rotated side is aimed at side sleepers. If you have broad shoulders or a firm mattress, measure your gap first, because one size does not fit those cases well.
How much do they cost?
At the time of writing, Derila is $59.99 for one, $49.99 each for two and $37.49 each for four. Sutera is $65.46 for one, or $58.19 each in the two-pack with pillowcases. Both are sold direct rather than in shops.
What is Sutera’s return policy?
Their product page states a 30-day sleep guarantee, and elsewhere on the same page a 90-day full-refund guarantee. Because those conflict, ask their support to confirm in writing before ordering. Derila states 60 nights.
Are they the same pillow with different branding?
They are not identical, but they are the same category: one-size contoured CertiPUR-US memory foam sold direct to consumers with cooling claims. The meaningful differences are the published height, Sutera’s rotating dual-zone shape, the price and the returns.
