Queblox Double Mattress 4FT6 11Inch 7-Zone Memory Foam Pocket Sprung Medium Firm (135x190x28 cm)

What it is and why people look at it

This Queblox double mattress is a memory foam + pocket-sprung hybrid built around a 7‑zone ergonomic concept. On paper, the idea is straightforward: you get targeted support through different body areas (shoulders, back, hips, and legs), then add a memory foam layer that should contour to your shape for comfort.

It’s also positioned as medium‑firm. That matters because medium‑firm mattresses tend to suit a wider range of sleepers than softer feels, especially if you want support without feeling like you’re sinking in too much. It’s particularly relevant if you sleep warm too, as the description specifically mentions breathable fabrics and a memory foam layer designed to avoid heat build-up.

The essentials: what you’ll feel at bedtime

The most “real world” aspect here is the combination of individual pocket springs and a memory foam comfort layer. Pocket springs are commonly chosen for motion isolation, and this mattress is described as working silently and isolating movement so you’re less likely to be woken by a partner shifting positions.

The 7‑zone approach is meant to keep support focused rather than letting your body settle in one uniform feel. If you’re a back sleeper or a side sleeper, the brand claims the structure is aimed at helping with spinal alignment. It isn’t guaranteed for every body shape (no mattress is), but if you like the idea of zoning rather than a single support profile, this is the one to consider.

What stands out: motion isolation, edge support, and sleep comfort

Two details are worth putting under the microscope.

First, motion isolation. If you and a partner have different sleep schedules or you’re easily disturbed by movement, a pocket-sprung construction is the direction you’d usually choose. The description is explicit that you should get undisturbed sleep.

Second, reinforced edge support. This is one of those features that doesn’t sound dramatic in a listing, but it can make day-to-day living easier—especially if you sit on the edge of the bed. The mattress is described as stable and helping prevent roll‑off, so you’re more likely to use the full surface rather than feeling pushed back towards the middle.

Potential limitations to be aware of before buying

There are a couple of practical “depends” here.

Medium‑firm is a broad target. If you strongly prefer a plush, sinking feel, you may find this sits more in the supportive, medium‑firm bracket than a soft comfort mattress. Likewise, if you need very specific pressure relief (for example, very high sensitivity around shoulders or hips), zoning can help, but it might still be worth checking return options rather than assuming it will suit every pressure point.

Also, the product is vacuum‑packed and delivered in a box, which is convenient—just bear in mind that it typically needs time to expand and settle after unpacking (this is normal for this delivery style, even when it’s not described in detail).

Compatibility and setup notes (what to check)

The listing says it’s compatible with most bed bases, including sprung bases, bunk beds, slatted bases, and floor setups. That flexibility is handy if you’re replacing an older mattress.

However, there’s a specific caution for bunk beds: you should check the height of the bed guardrail in advance to make sure the mattress thickness doesn’t exceed it. Since the mattress thickness is stated as 28 cm, it’s worth measuring rather than guessing—especially for bunk setups.

Tech & assurance details that matter

You don’t have to overthink certifications, but it’s still useful when deciding between similar hybrids.

• The foam layers are stated to be CertiPUR‑US certified.
• The fabric carries the OEKO‑TEX STANDARD 100 label, described as ensuring it’s free from harmful substances.

If you’re the kind of buyer who likes peace of mind on materials, these are the sorts of details that make a real difference compared with mattresses that don’t clearly state anything about foam or fabric safety.

Who it’s for (and who should skip it)

It makes sense if you want a medium‑firm double mattress with a memory foam comfort layer, pocket springs for reduced partner disturbance, and a comfort plan based on a 7‑zone ergonomic idea. It also looks like it suits warm sleepers on the strength of breathable fabrics in the description.

It may not suit you if you want a very soft, “sink in” mattress, or if you’re extremely particular about pressure relief in a very specific area. In those cases, medium‑firm zoning and contouring might not deliver the comfort curve you’re after.

Small scenario: a night that feels different

Imagine you share a bed with someone who turns over often. With a mattress like this, the pocket springs are intended to reduce motion transfer, so their movement shouldn’t travel as much through the mattress. Add the memory foam contouring layer on top, and the goal becomes less “hard spot” pressure and more consistent comfort as you change positions through the night.

FAQ

Is this mattress good for back and side sleeping?

The description explicitly mentions comfort for back sleepers and side sleepers. As with any mattress, personal preference and body shape matter, but the 7‑zone design is aimed at those positions.

Will it sleep hot?

The listing says the memory foam layer conforms precisely without trapping heat, and that breathable fabrics help maintain a cool and dry microclimate. If you know you sleep warm, that’s a meaningful point to check.

Does it help with partner disturbance?

Yes, the mattress is described as using a robust pocket-spring system that isolates movement and sleeps silently, so you’re less likely to be disturbed by a partner.

Can I use it with slatted bases?

The listing states compatibility with slatted bases, along with sprung bases, bunk beds, and floor setups.

What should I check for a bunk bed?

Check the height of the bed guardrail first, so the mattress thickness (28 cm) doesn’t exceed it.

Final verdict

Worth considering if you’re after a double mattress that leans medium‑firm, combines a memory foam comfort feel with pocket springs for motion isolation, and includes materials reassurance (CertiPUR‑US for foam and OEKO‑TEX for the fabric). It’s also a practical choice when you want a mattress that should work across most base types.

However, it might not be the best match if you know you want a softer, more cushioning feel, or if your comfort requirements are very specific and you’re not confident a medium‑firm hybrid will match them. In that case, it’s sensible to weigh your priorities—support and reduced disturbance versus deep plush comfort—and make sure you can manage the return/settling period after box delivery.
