A proprietary design and hand-sewn here in the U.S.A., they come as a complete set; including wire frame base, mattress and two pillows. They measure 7-7/8” wide x 13-1/4” long. Mattress and pillows are both machine-washable; with the mattress’s batting sewn-in to prevent lumping. Wire frame base is easy to clean with our chlorhexidine solution and is supported by four sturdy feet. Chaise lounges can be used both inside the habitat or outside the habitat; giving your dragon a familiar and comfortable place, whether beside you on the couch watching TV or keeping you company while you are at your computer. They can even be used as their basking spot underneath their basking bulb. Appropriate for adults or sub-adults (12” or better, nose to end of tail); however not good for juveniles if you find them underneath the chaise lounge where they will not be exposed to the UVB that they need. Since these chaise lounges are hand-sewn, the fabric’s pattern placement may vary and there may be small size variations.
