We make sofa bed mechanism instead of finished sofa bed.

This is an one-step high end sleeper mechanism.No need to take seat cushion or back cushion away before you open the mechanism.

It has low leg and high leg versions.

It enjoys very small clrearance between armrests and mechanism for better comfort and safety.

It passed 2000 cycles test to use everyday.

It passed the TUV test.

It enjoys very low head tube in close position to increase about 30% container loading capacity for finished sofa bed.

Move the cross bar to pillow area for the sleeping comfort.

No sagging design like a metal grid but softer than metal grid, it is easy for people to turn over in the bed but metal grid is too hard for people to sleep.

The mattress is 190cm long but total length of sleeper in open position is 200cm only. 

Compared to Bi-fold the total length of sleeper is 225cm but mattress is 182cm, compared to 3 fold the sleeper is 210cm but mattress is 185cm. Mattress longer and save floor space. Especially mattress length is very important for sleeping in the night,short mattress will make people to catch a cold.
