Medium Firm Gel Memory Foam Double Mattress (4FT6) – Hybrid Pocket Spring Support
Sleep should feel steady, cool, and kind to your back. This hybrid double mattress blends gel memory foam with 7-zone pocket springs to support your body where it needs it most. It suits back, side, and stomach sleepers who want a balanced feel—not too soft, not too hard.
The biggest win is the mix of pressure relief and stable support. With medium firm double mattress comfort, your spine stays better aligned, and your partner’s movement is less likely to wake you up. The breathable top also helps reduce heat build-up for a fresher night.

How to Use It?
Place the boxed mattress in your bedroom, unbox it on the bed frame, and carefully cut the outer plastic wrap so it can expand. Let it rest flat for 24–72 hours before judging the feel.
Tip: Use a breathable mattress protector to keep the cover cleaner and help the foam last longer. Avoid bending the mattress sharply, and rotate it every few months for more even wear.
Why Buy This Product?
This mattress is a reliable pick for everyday comfort because it combines zoned spring support with pressure-relieving gel foam. If you want orthopaedic double mattress style support with a cooler, steadier feel, it offers strong value in the hybrid mattress category.

Additional Information
How long should I wait after unboxing before sleeping on it?
Mattresses that arrive compressed usually need some time to expand and air out after opening. Many people find it more comfortable to wait until it has mostly regained its shape, and to keep the room ventilated during that period.
If I’m a light sleeper, will I feel my partner moving around at night?
Hybrid designs with individual pocket springs and a foam layer can reduce how much movement travels across the surface, but it may not remove it completely. The amount you notice can also depend on your combined body weight and how close you sleep to the center.
What’s the practical way to keep it clean without damaging the cover?
A removable protector is often used to reduce exposure to sweat and spills, since many knit covers aren’t meant for heavy scrubbing. For routine care, gentle vacuuming and spot-cleaning with mild detergent is commonly suggested, and it helps to avoid soaking the foam.
Overall User Feedback
People tend to appreciate the medium-firm feel combined with zoned support, especially when they want steadier spinal alignment and less “sink.” The breathable cover and motion isolation are often seen as useful for shared beds, though some users mention a short settling or airing-out period after unboxing and that firmness can feel different depending on body type.
Pifmarket’s Review
We like the balanced approach of a hybrid build with gel memory foam on top and zoned pocket support underneath, as it generally suits mixed sleeping positions without feeling overly soft. The breathable cover and edge reinforcement are practical touches, but you should expect a brief expansion period after delivery, and the medium-firm feel may take a few nights to adjust to if you’re used to a softer surface.
