Which cushion is better for preventing pressure sores?

Both use medical-grade egg crate foam to distribute weight and improve air circulation. The DMI is thicker at 4 inches, which may provide more relief for heavier users, while the Hermell is specifically marketed for long-term wheelchair users.

Can the covers be washed?

The Hermell cushion includes a zip-off cover designed for easy cleaning. The DMI cushion is listed as spot clean only, making it less ideal for users concerned about frequent spills or incontinence.

Do these cushions stay in place on a chair?

The DMI cushion features a non-skid surface to prevent sliding. The Hermell is described as offering a slip-free seat, but it relies more on its fit within a wheelchair frame.

Is the DMI cushion worth the lower price?

Yes, for most users the DMI is the better deal because it is $5.90 cheaper and offers an extra inch of foam plus back support. Only choose the Hermell if you specifically need a removable cover or flame-retardant materials.
