Two butterfly-shaped memory foam pillows that look almost identical. Here's how they really differ in size, price and return policy, and which one fits the way you sleep.

A butterfly pillow is a contoured memory foam pillow shaped a bit like a butterfly: a softer, lower center for your head and raised "wings" on the sides. Instead of one flat surface, it has zones for different sleeping positions.
They're popular with people who wake up with a stiff neck, switch positions at night, or are tired of folding a flat pillow in half. They're a comfort product, not a medical treatment.
Both are well-designed contour pillows. The differences that matter are size, the return policy and price per pillow.
Based on each brand's official page and return policy at the time of writing. Green marks the stronger option for that row.

Our verdict: the two pillows are very similar in design and comfort. Derila Ergo wins for most people thanks to the longer 60-day return window and the lower price per pillow in its bundle. Choose Melara if you specifically want a bigger pillow and you're comfortable deciding before you sleep on it, since its returns only cover unused items.
Four things matter more than the marketing.
Side sleepers benefit most from the wings. Back sleepers use the center. Mostly stomach sleepers usually need a lower pillow, so be careful with any contour pillow.
A smaller pillow fits standard pillowcases and travel bags. A bigger one gives broad shoulders and restless sleepers more room.
Memory foam takes 5 to 7 nights to get used to. A longer window and clear conditions lower your risk. Always read whether used pillows can be returned.
Bundles bring the price down a lot. If you're unsure about memory foam, start with one; if you already love contour pillows, a bundle is the better deal.
Health note: a supportive pillow can improve comfort, but it doesn't treat medical conditions. If you have ongoing neck pain, frequent headaches or loud snoring with daytime tiredness, talk to a doctor.
Answer 4 quick questions and get a personal suggestion.
Both pillows deliver the same butterfly idea: zoned neck support, memory foam that holds its shape and a cooler cover. Derila Ergo takes the top spot for its longer 60-day window and better bundle price. Pick Melara if a bigger pillow matters more to you.
