Uliyati Double Memory Foam Mattress (Medium) 135x190x20cm, CertiPUR-US Certified

The essentials (what it is and why people buy it)

This Uliyati double mattress is a 20cm memory foam build aimed at pressure relief and a cooler night’s sleep. On paper, it’s designed to mould to your body shape while still keeping a supportive base under you, with extra focus on breathability thanks to gel memory foam and bamboo charcoal foam in the layer stack.

If you’re the kind of sleeper who notices pressure points (shoulders, hips, lower back) or tends to wake up feeling stiff, a medium memory foam option like this is often chosen because it can feel more “hugging” than firmer foams. That said, memory foam isn’t magic: if you prefer a springy feel or you run hot regardless of materials, it may not solve every comfort issue on its own.

What matters most: comfort, support and sleep feel

The mattress uses a four-layer foam system: - 1cm comfort memory foam - 2cm gel memory foam - 2cm bamboo charcoal foam - 15cm supportive base foam

The brand’s approach is classic memory foam: the top layers respond to your contours, while the thick base is there to help you stay supported rather than sink too far. In everyday terms, it should give you that slow “settle in” feeling when you first lie down, followed by more consistent support through the night.

It’s also positioned for targeted support across key areas like the head, neck, shoulders, spine and hips. If you like your mattress to help with alignment and reduce morning aches, this is the type of build you’d look at.

Cooling and breathability: where it tries to earn its place

Heat build-up is one of the main reasons people move away from thicker, less breathable foams. Here, the intent is clear: gel memory foam plus bamboo charcoal foam are both included to help air circulation and dissipate heat, aiming to prevent overheating.

Keep expectations realistic though. Cooling features can help, but your room temperature, bedding and your own sleep temperature habits still matter a lot. If you already sleep very warm, you may still want to think about lighter duvets and breathable covers alongside the mattress.

Cover and everyday maintenance (the practical bit)

The mattress cover is described as breathable and skin-friendly, and the grey fabric is said to be dirt-resistant, which should help reduce how quickly minor marks show. For cleaning, the guidance is simple: wipe the surface with a damp cloth to keep it looking fresh.

This isn’t a “tumble it and forget it” situation in the description you’ve provided, so it’s worth being comfortable with spot-wiping as your main routine.

Mattress in a box: setup time you should plan for

Like many foam mattresses, it arrives vacuum-sealed and compressed in a compact cardboard box. After unpacking, it will inflate and reach 90% of its size in a few hours, but the full expansion is expected to take 24 to 72 hours. Ambient temperature affects how fast it expands, with warmer conditions typically speeding it up.

Plan for that delay. If you’re putting it on a spare bed and need it ready immediately, this is the one detail that can catch people out.

Certifications and purchase confidence (what you know you’re getting)

This mattress is described as CertiPUR-US certified and OEKO-TEX certified, with materials stated to be free from harmful substances. It’s also presented as durable, maintaining shape and performance over time.

The support package included is a 100-night trial and a 10-year warranty. That’s the sort of safety net that matters with memory foam, where feel can be personal.

Who it suits best (and who should think twice)

It’s a good fit if you want a medium memory foam mattress that prioritises pressure relief, includes gel and bamboo charcoal for breathability, and you’re happy with a foam “moulding” feel rather than a bouncy one.

It might not be for you if you’re sensitive to the slower memory foam response, you strongly prefer firm support without sinking, or you’re a very hot sleeper who needs major temperature control beyond what breathable layers can reasonably achieve.

Also worth noting: the mattress is medium, so if you’re looking for a notably plush mattress or a notably firm one, you may find it lands more in the middle of the spectrum.

Is it worth it?

Worth considering if you’re shopping for a double memory foam mattress with a breathable, multi-layer build and you like the idea of targeted pressure relief. The foam composition (including gel and bamboo charcoal) and the “mattress in a box” setup are practical reasons people tend to choose this style.

You may want to skip it if you dislike memory foam contouring, need immediate full inflation, or you already know you sleep extremely hot and want stronger cooling performance than foam breathability alone can offer. In general, this feels like a mid-range comfort choice rather than an ultra-firm or ultra-plush specialist.

Quick FAQs

How long does it take to fully expand after unpacking?

The mattress should reach 90% of its size in a few hours, but full expansion is expected to take 24–72 hours. Warmer room temperatures generally speed it up.

Is it designed to stay cool during the night?

It’s set up with gel memory foam and bamboo charcoal foam to support breathability and heat dissipation, but your bedding and room temperature still play a big role.

What’s the firmness like?

It’s described as a medium mattress. If you’re used to very soft or very firm feels, you’ll need to treat “medium” as a midpoint rather than a guarantee of your preferred comfort.

How do you clean the cover?

The guidance is to wipe the surface with a damp cloth. That’s a straightforward routine, but it’s more spot-clean than deep clean in the information provided.
