We recommend measuring your pet from nose to tail while sleeping. Use that measurement to determine which size bed will work best. Our Overstuffed Sofas measure as follows: Small*- Inside: 19”x14” (sleeping area) Outside: 30”x20” Pillow : 29”x19” (as measured when removed from the bed) Bolster Width: 5” Back & side height: 8” Large*- Inside: 26”x20” (sleeping area) Outside: 40”x30” Pillow : 39”x25” (as measured when removed from the bed) Bolster Width: 6” Back & side height: 11” X-Large*- Inside: 34”x24” (sleeping area) Outside: 54”x36” Pillow : 48”x31” (as measured when removed from the bed) Bolster Width: 8” Back & side height: 13” *Note that this entire bed is made of polyester filling and is basically a giant pillow. As do pillows, the item will spread out and flatten a bit over time. When in doubt, go with a larger size. Having a bed that is a bit too big is better than one that is too small, and cannot be used.

We recommend comparing the dimensions of the seat to your pet(s) sleeping area. Measure your pet, from nose to tail- in their typical sleeping position. We then suggest cutting a piece of newspaper or butcher paper to the interior dimensions of the bed you’re interested in (the overstuffed sofa in XL measures about 32"x22" in the inside sleeping area). Place the paper on the floor, and have your pet(s) sit on the paper. If they fit in the space provided, the item will work. When in doubt, order up in size.
