Product Description
The MOBB Ring Cushion is a ring-shaped (donut) seat cushion with an open centre. Body weight is carried on the surrounding ring, so the tailbone and perineal area sit over the opening and bear no direct pressure. It is available in 16″ and 18″ diameters and carries a lifetime limited warranty.
The principle is the same one behind every coccyx cut-out cushion, taken to its simplest form: if the painful area is suspended over a gap, it cannot be loaded. Padding reduces the force on a sore area; an opening removes it. That is why ring cushions are the standard recommendation for the specific group of conditions where any direct contact is the problem — after childbirth, after haemorrhoid or perineal surgery, with pilonidal sinus, or with a bruised or fractured tailbone.
The trade-off is that a ring concentrates load onto the ring itself. That is entirely appropriate for short-to-medium sitting periods during recovery, but it makes a ring cushion a poor choice for all-day seating or for anyone at risk of pressure injury — in those cases a contoured or gel cushion that spreads load broadly is the safer option.
Key Features
Open Centre Removes Direct Pressure Weight is carried on the ring, so the tailbone and perineal area bridge the opening and bear no load at all — the difference between reducing pressure and removing it.
Two Diameters: 16″ and 18″ 16″ suits a standard dining or office chair and a narrower build; 18″ gives a wider seating surface for a broader build or a wider chair.
Common Post-Surgical and Post-Partum Use Widely used after childbirth, haemorrhoid surgery and perineal procedures, and for pilonidal sinus and coccyx injury.
Portable and Light Light enough to move between a chair, a car seat and a work seat, which matters during a recovery period measured in weeks.
Lifetime Limited Warranty Backed by MOBB Home Health Care’s lifetime limited warranty against manufacturing defects.
Ring Cushion or Coccyx Cut-Out Cushion?
Both remove pressure from the tailbone, but they suit different problems. A ring cushion has a fully enclosed opening, which also relieves the perineal area — that is why it is the usual choice after childbirth and perineal or haemorrhoid surgery. A coccyx cut-out cushion, such as MOBB’s Convertible Coccyx Cushion, has a U-shaped channel open at the back that relieves the tailbone only, while keeping a continuous supportive surface under the thighs.
For sitting comfort over longer periods, the coccyx cut-out is generally the more comfortable of the two, because load is spread across a larger area. For short recovery sitting where perineal contact is the issue, the ring is the correct tool. Use a ring cushion for the duration of recovery rather than as a permanent daily seat.

Frequently Asked Questions
What is a ring or donut cushion used for?
It suspends the tailbone and perineal area over an open centre so they carry no weight while seated. It is most commonly used during recovery — after childbirth, after haemorrhoid or perineal surgery, with pilonidal sinus, and with a bruised or fractured coccyx. The aim is to make sitting tolerable during healing rather than to provide long-term seating support.
Should I use a ring cushion all day, every day?
Generally no. A ring concentrates body weight onto the ring itself, which is fine for the shorter sitting periods of a recovery but not ideal for full-time seating. If you sit for most of the day, or if you have any risk of pressure injury, a contoured foam or gel cushion that spreads load across a wider area is the safer choice. Ask an occupational therapist if you are unsure.
Which size should I choose, 16″ or 18″?
Match it to your chair rather than to yourself. The 16″ suits a standard dining chair, office chair or a 16″ wheelchair seat. The 18″ suits a wider armchair or an 18″ wheelchair, and gives more surface area for a broader build. A cushion wider than the seat will rock, so if the chair is narrow, choose the 16″.
Is a ring cushion suitable for haemorrhoids?
It is one of the most common reasons people buy one, because the open centre keeps pressure off the affected area while seated. It relieves the symptom rather than treating the cause, so use it alongside whatever treatment your clinician has recommended, and see a doctor if symptoms persist or worsen.
Summary
The MOBB Ring Cushion is a donut-shaped seat cushion with an open centre that suspends the tailbone and perineal area so they bear no direct pressure. Available in 16″ and 18″ diameters with a lifetime limited warranty, from Factory Direct Medical.
Important Notice: This product is a comfort aid and is not a substitute for professional medical advice, diagnosis or treatment. It relieves symptoms while seated and does not treat the underlying condition. Seek clinical advice if pain persists or worsens. A ring cushion concentrates load onto the surrounding ring and is not appropriate for full-time seating or for anyone at risk of pressure injury — consult an occupational therapist for long-term seating needs.
