The Classic Spring Mattress has been especially developed for places that have a lot of people using them at the same time, like hotels, dorms, and rental houses. It provides dependable support and great durability. Plus, it can last up to 15 years with regular use.
Product Introduction
Mattresses in hotels, dormitories and rented flats undergo very rough treatment. People sit on the mattresses'edges. Dormitories usually sleep more than one person. Frequent changes of renters in apartments. With standard foam mattresses after1-2 years they can really start showing their age. The corners get crushed in. The people are not only disturbed by the lack of comfort but also end up getting back pain. You are forced to change the mattresses regularly - at an average interval of 2 – 3 years - increasing your costs and decreasing your profits, respectively.
Our Solution – Bonnell spring mattress built for heavy use.
A Bonnell spring mattress of ours is made of hourglass-shaped steel coils with interconnected springs that evenly distributes weight all over the mattress surface. To avoid edge collapse from daily sitting, the edge springs are strengthened with a thicker wire.
Premium foam mattress typically sagging after 1–2 years, our Bonnell spring mattress is consistent supportive over 10–15 years. The mattress is designed with 1.2–1.5 tons bearing capacity per person and options for thickness range 6–12 inch, so it can easily cope with frequent use. The open coil design ensures free airflow at all times - a comfort factor that especially hot climate sleepers appreciate.
Benefit: longevity of 15 years versus foam's average of 2–3 years. Low mattress changing expenses. Minimal complaints.

Product Comparison – Bonnell, Foam & Pocket Spring
A typical foam mattress will sink and wear out within 2–3 years while a spring mattress with Bonnell coils can last up to 10–15 years - 5x longer.
Foam mattress edges give away easily when sitting or getting to your feet. Bonnell coils that support the mattress edges made of 2.3–2.5mm wire – edges remain strong and supportive.
If you are about 80kg–100kg then foam mattress will work for you. If you are 120–150kg the better choice will be Bonnell.
Foam mattress is a heat sponge – you are likely to overheat in the night. A Bonnell mattress with its open-coil construction promotes ventilation – sleep remains cool and refreshing.
Foam will be cheaper initially but you'll probably replace it 5 times during this period. In 15 years: 5 replacements in foam vs one Bonnell.
Mattress with Bonnell defect rate: 0.5% vs 1–3% for foam mattresses. 15-year warranty vs 1–3 years.
Which type of mattress is better? Pocket springs vs Bonnell.
Pocket springs isolate movement well and the mattress shape follows better – it's a mattress of a higher class. Pocket spring costs a bit more. Best option for luxury accommodation and premium retail units.
Springs with Bonnell are more comfortable with the level of hard support and lower expenses. Suitable for high traffic use - budget hotels, hostels, rentals, and governmental housing.
Better to go with Bonnell if you want a more durable and economically-efficient choice. If, on the other hand, you prefer comfort of the highest level then pocket springs will best suit you.
