With the [OG-500](https://www.stanmekanizma.com/en/u/OG-500/) pull-out mechanism, you pull the frame forward and a hidden upholstered extension rises 18 cm on an S-shaped path, forming a bed level with the seat. With the [OG-510](https://www.stanmekanizma.com/en/u/OG-510/) corner mechanism, a wheeled inner frame slides out from under the seat and a hidden platform rises about 20 cm to seat height. Both come in a small size: [OG-501](https://www.stanmekanizma.com/en/u/OG-501/) and [OG-511](https://www.stanmekanizma.com/en/u/OG-511/). How does the Puma mechanism work? [OG-540](https://www.stanmekanizma.com/en/u/OG-540/) converts a sofa into a bed. Lift the seat by its front edge: the mechanism first slides it forward about 10 cm, then opens it into a bed, so the seat and backrest fabrics never rub. The backrest stays fixed. The left and right mechanisms are linked by a 30×20 box section. How many positions does the ratchet armrest have? The top of [OG-530](https://www.stanmekanizma.com/en/u/OG-530/) tilts in three 15° steps. At 60° the lock releases and the armrest returns when lowered. The two mechanisms are welded into one set with ø16 tubes; tube length is made to order. Black powder coat as standard; OG-530-Z is zinc plated. What size is the tubular backrest mechanism? [OG-520](https://www.stanmekanizma.com/en/u/OG-520/) is 22 cm high as standard; OG-520-26 is 26 cm. The backrest travels about 30 cm forward and back. Tube length is made to order to suit the sofa design; 33 cm is the most common. Is the coffee table mechanism spring or gas spring operated? [SH-500](https://www.stanmekanizma.com/en/u/SH-500/) is spring-assisted as standard; SH-500-G uses gas springs. The top rises 226 mm and moves 323 mm forward. Each set includes two mechanisms, a telescopic link and two springs. ## Other families [Bed Lifts](https://www.stanmekanizma.com/en/products/bed-lifts/)[Storage Hinges](https://www.stanmekanizma.com/en/products/storage-hinges/)[Sofa Bed Mechanisms](https://www.stanmekanizma.com/en/products/sofa-bed-mechanisms/)[Adjustment & Connection](https://www.stanmekanizma.com/en/products/adjustment-connection/)[Complementary Products](https://www.stanmekanizma.com/en/products/complementary-products/)
