Airlift™ Thrones are the next evolution in DW throne technology. Combining the workhorse features of DW’s 9000 line of thrones, Airlift™ thrones also include a sturdier quad-leg folding base, and effortless pneumatic height adjustment (U.S. Patent No. 7,718,878). The 9120AL design includes an optional backrest (sold separately, and exclusive to the Airlift™ model) for those players that desire more support, while the 9100AL incorporates a more traditional seat top. [20" min / 27.5" max height] ***This item may ship direct from the manufacturer. Please contact us for estimated delivery if needed.***
