How to choose
Select the model that matches the exact mattress size. The wedge belongs under the mattress with the non-slip side down; it is not a personal pillow for placement above the mattress.
Confirm that the frame, headboard clearance and bedding can accommodate the incline. Comfort with elevation is personal, so allow time to adjust.
Measure before ordering
Measure mattress length, depth, height difference and the center gap. Check the bed or chair manufacturer’s instructions before adding any connecting or positioning accessory.
