I recently purchased some acacia rockers that didn't have cushions. They have a seat measurement of 19" x 23" that none of the stores I checked carried that measurement. I checked on here for that measurement and a lot of items came up but had different sizes. I persisted to run through the listings and this was the only one I found. They were more expensive than I expected to see, but once they arrived the quality and design aspect of piping sold me. Plus they are thick with a filling that doesn't just collapse when sitting. My rockers don't have an open space on the back, but these won't slide through if you do. They don't have ties. The ivory is a wonderful neutral tone true to color. They came well packaged and arrived quickly. They are quality plus.
