Product Introduction:
Pillow-top mattresses for hotels and dorms are expensive and take a lot of material and space. Pillow-top is like adding a few layers on top. It results in more materials, more work for delivery guys, more volume for shipping.
But you don't really need extra padding in high traffic areas. You just need a comfortable and reliable support that won't give out with everyday activity and frequent check-ins and check-outs.
Pillow-top also adds to the cleaning and housekeeping burden. The thick padding complicates sheet changes and generates heat.
Our Solution - Tight Top Spring Mattress.
A flat, firm surface without thick cushioning. The mattress is easy to construct and is simple to look after as the thick cushioning layers are absent. It is manufactured and assembled on a durable, long-lasting 10-15 year basis.
Core: Bonnell spring system with reinforcing edge frame and heat-treated coils. Final thickness: 18-22 cm. Load capacity: 120 kg per person.
Comfort layer - high-density foam (28-32D) + antibacterial nonwoven fabric for comfort and hygiene (25g/m²).
Firm support and the mattress that will save your effort and money in maintenance are just two of the great features of this product. It is the type of mattress designed for environments that are always crowded and where convenience is the first consideration.

2. Winding a helical spring: Shaped like an hourglass with 4 to 6 turns, with a tolerance of ±0.5mm
3. Hooking springs: Helical steel wires + reinforced edge frames
4. Removing internal stress by heat treatment – thus, elasticity is enhanced
5. Covering comfort layer: High-density foam (28–32D) + antibacterial nonwoven (25g/m²)
6. Cover joining: Knit fabric + tight top finishing
7. Checking quality: Real-time monitoring, height ±0.5mm
Automation rate: Over 95%. 20 types of machines. <0.5% defect rate.
