Sleeping Duck vs WinkBeds
Why choosing a mattress feels harder than it should
Let's be honest choosing a mattress is a big decision, and getting it right matters.
WinkBeds offers three different mattresses The WinkBed, GravityLux and EcoCloud. Each uses a different construction and material approach, with multiple firmness options across the range. When combined, customers are effectively being asked to choose between eight different mattress options before they have even slept on one.
Once that choice is made, the feel of the mattress cannot be adjusted internally. If it turns out not to be right, your options are limited. You return it, exchange it, or try to change the surface with a topper.
That kind of guesswork is exactly what Sleeping Duck set out to remove.

Instead of building dozens of mattresses, our founders both aerospace engineers, asked a different question:
How do we build one mattress that genuinely works for everyone?
The answer is the Sleeping Duck Mach II.

It's built from the inside out. At the core is a twice tempered steel spring system that keeps your spine properly aligned and prevents sag over time. On top of that, we add precision foams for comfort and pressure relief, finish it with a removable, breathable bamboo BreatheTech cover to keep things cool and clean and build in ComponentAdapt, so you can adjust the firmness inside the mattress until it feels right for you.
ComponentAdapt - real adjustability, built in
ComponentAdapt means you don't have to guess your firmness on day one. It's built inside the mattress and lets you change how it feels properly until it's right for you.
You can choose from Extra Soft, Medium, Firm or Extra Firm, adjust each side independently, and fine tune things during your trial with help from our customer service team. If you need a different firmness, we'll send it out at no extra cost.
No toppers. No add ons. Just a mattress that adapts to you.

BreatheTech Cover:
Washable, Breathable & Naturally Comfortable

A mattress surface should be easy to clean. Over time, sweat, body oils, skin cells and dust naturally build up that's part of normal sleep.
WinkBeds uses a quilted pillow top and stitched sleep surface that isn't designed to be removed and machine washed. Over time, what settles into that surface stays there.
Sleeping Duck's BreatheTech™ Cover is built differently. It unzips completely and is machine washable, so you can keep your sleep surface clean, fresh and hygienic without special cleaners.
Sleeping Duck = removable, washable cover
WinkBeds = fixed sleep surface
Sounds great but I have a few questions?
It's engineered specifically for back support.
The Mach II is built around a twice tempered steel spring system designed to keep your spine aligned and prevent sag over time. That structure supports your body consistently, rather than relying on thick foam layers that soften and compress.
It’s not just a different feel. It’s a different foundation one designed to maintain support night after night, not just feel comfortable on day one.
Choosing firmness at checkout is a guess. ComponentAdapt is a system.
With WinkBeds, you select a firmness before you've slept on the mattress. If it's not right, your options are limited to returns or add-ons.
ComponentAdapt is built inside the mattress itself. You can switch between Extra Soft, Medium, Firm, and Extra Firm, adjust each side independently, and refine the feel during your trial. If you need a change, we send the components free of charge and help you get it right.
It's not selecting a mattress.
It's engineering one to suit you.
WinkBeds focuses on premium materials, handcrafted construction, and zoned support across different mattress models. The feel is selected at purchase and remains fixed.
Sleeping Duck focuses on engineering and adjustability. The Mach II is designed to deliver consistent back support through its internal spring architecture and allow firmness to be changed inside the mattress if your needs change.
It is not just about how a mattress is built.
It is about whether it can adapt once you start sleeping on it.
