Promotion 2 fold sleeper mechanism 2500 Series (Tubular construction).This is of promotion style sofa bed mechanism, it will save cost when it is compared to our angle frame sofa bed mechanism DF00 series.
We still recommend you to use our DF00 series because of more comfortable sitting and sleeping, more durable and safety, this is the value for end users and long term business.
If cost is really important for you, then 2500 is choice for you, but our TFN00 maybe is the best solution for you too, because its depth mounting space is 64cm compared to 80cm by 2500 series, also the mattress thickness can go to 10cm and open length can go to 190cm compared to 183cm by 2500 series.
