DAJIYUHC King Mattress 5FT 10 Inch Hybrid Mattress in a Box (150x200cm) – Medium Plush, motion isolation
Product description
The essentials
This DAJIYUHC king-size hybrid mattress comes in a box and is designed around a foam-and-spring mix. On paper, the goal is simple: give you a medium plush feel with extra comfort from gel-infused memory foam, while the independent pocket springs help absorb movement so you’re less likely to feel your partner’s turning.
It also leans into practical sleep comfort details: there’s mention of an airflow-focused foam layer (egg box design) and a cover made with skin-friendly rayon fabric. Add in the “fiberglass free” note, plus certifications named in the listing, and you get a mattress that’s trying to tick both comfort and safety boxes rather than only chasing softness.
That said, it’s still a hybrid in a box, so it won’t feel “fully settled” the same day. The listing asks for 24–72 hours after unboxing for it to regain its full shape, and it can take longer in cooler conditions.
Key features that affect real sleep
What stands out most here is the combination of gel memory foam and independent bagged springs. If you like the slow-contouring feel of memory foam but don’t want to feel trapped or overheated, the gel infusion and the egg box airflow design are the sort of touches that aim to keep things more comfortable through the night.
The motion isolation angle is also a proper selling point for couples. Independent packaging springs are meant to absorb noise and vibration caused by a partner’s movement, which can make a noticeable difference if you share a bed and one of you tends to move often.
You also get a breathable construction approach. The listing talks about a breathable knit layer and improved cover breathability (it states an improvement by 30%). It’s not a guarantee of “never warm”, but it does suggest they’ve designed for airflow rather than just stacking comfort materials.

Where it shines (and where it may not)
This is a solid fit if you want a medium plush hybrid that targets two common pain points: partner movement and temperature feel. If you’re shopping for a “sleep-through-the-night” upgrade on a practical timeline, the box delivery helps, and the independent springs/motion isolation claim is relevant if you share the bed.
It’s also worth considering if you like a mattress that stays breathable on the surface rather than relying only on soft top layers. The egg box airflow design and breathable knit element suggest it’s built with day-to-day ventilation in mind.
However, it may not suit you if you prefer a firmer, more supportive feel. “Medium plush” usually sits more on the softer side of the comfort spectrum, so heavier sleepers or people who like a very buoyant, “lift” feel may find it less supportive than they hoped—especially before it fully expands.
Also, take the expansion timing seriously. If you need it perfect immediately after delivery, you may be disappointed, the listing is clear that it can take 24–72 hours (and sometimes longer in cold conditions) to return to full size.
Getting the best from it
Once you unbox it, plan to let it expand properly before you judge comfort. A useful micro-scenario: imagine taking the mattress out in the afternoon, letting it decompress overnight, then making the bed the next day—this is exactly when you’re more likely to notice the true feel rather than a temporary, compressed firmness.
Climate matters too. The listing mentions faster expansion in warmer rooms and slower recovery when it’s cold at delivery. If your bedroom runs chilly, give it that extra time.
If you’re sensitive to sleep temperature, it’s also reasonable to expect the gel infusion and airflow layers to help more than a basic foam mattress, but personal comfort can still vary depending on your bedding and room conditions.
Final verdict
Is it worth it?
Buy this DAJIYUHC king mattress in a box if you’re after a medium plush hybrid with gel-infused memory foam, airflow-focused materials, and a clear attempt at motion isolation for couples. The named certifications (CertiPUR US and Oeko-Tex Standard 100), the “fiberglass free” note, and the 10-year warranty give it more credibility than purely comfort-led options.
You may want to skip it if you know you prefer a firmer feel, or if you can’t afford to wait 24–72 hours after unboxing for full shape recovery. It also might not be the best match if you’re mainly searching for a super-bouncy, ultra-supportive spring feel, because this is designed around memory foam comfort on top.
Who it suits best: couples who are bothered by turning, plus anyone who likes a softer, contouring surface but still wants airflow.
Who should avoid: sleepers seeking a distinctly firm mattress, or anyone needing immediate “ready to go” comfort the day of delivery.
