The Slily 12 Inch Double Mattress is made for people who want steady support without losing that soft, cozy feel. It blends memory foam with pocket springs to help your body settle in a natural position, so you wake up feeling looser and more rested. If you share a bed, it also helps keep the night calm and quiet, even when someone turns over.
This 12 inch double mattress gives a balanced, medium-firm feel that suits most sleepers—back, side, or mixed. The foam eases pressure around common sore spots, while the springs add lift and help stop that “stuck” feeling some soft beds cause. It arrives rolled in a box, so moving it into a bedroom is much simpler than a traditional delivery.
The standout benefit is comfort that stays supportive night after night. With medium firm memory foam mattress comfort and spring-backed strength, it helps reduce pressure and keeps your spine lined up. For couples, the motion isolation mattress design can mean fewer wake-ups and deeper sleep.

Additional Information
How long should I wait after unboxing before sleeping on it?
It’s usually a good idea to let a rolled mattress fully expand and air out before using it. Some people choose to sleep on it sooner, but the feel can change as the foam and springs settle over the first few nights.
If I share the bed, will movement from the other side be noticeable?
Pocket springs tend to reduce motion transfer because each spring can move independently. That said, how much you notice can still depend on body weight differences, the bed base, and how restless each sleeper is.
Worried about keeping it clean—can I use a mattress protector, and how should I care for it?
A removable protector can help with spills, sweat, and everyday staining without changing the general feel too much. Basic care usually comes down to keeping it dry, letting it breathe occasionally, and following any label guidance for cleaning rather than soaking the mattress itself.
Overall User Feedback
Buyers of medium-firm memory-foam-and-pocket-spring mattresses often like the balanced support, especially for reducing pressure around the hips and shoulders and keeping a steadier feel across the surface. Co-sleepers commonly mention less disturbance from movement compared with older spring designs, though some people still need time to adjust to the firmness. A few note that boxed delivery can come with a brief “new mattress” smell and that comfort may shift slightly as it finishes settling.
Pifmarket’s Review
Our team tends to appreciate the straightforward medium-firm feel and the way pocket springs and foam can work together to keep the surface supportive without feeling overly hard. Motion isolation is often noticeable in day-to-day use, particularly if one person changes position at night. The main drawbacks are that it may need a settling period after unboxing, and the firmness won’t suit everyone, especially those who prefer a softer, deeper sink-in sensation.
