You may have clicked over here from our article where we’ve reviewed some of the top toilet seats for heavy people. As we mentioned there, heavy-duty toilet seats can be a great option. However, some people prefer a commode chair that can be placed directly over their standard toilet rather than replacing their existing toilet seat. 

There are a few reasons why this can be a good choice: if you are sharing the bathroom with other members of the house that want to use the standard toilet seat, a commode chair lets you place it directly over the toilet when you need to use it without making any modifications to the toilet (smaller people in the house may not be comfortable on an extra wide/large toilet seat).

Another advantage to the bariatric commode is that it is portable– if you are not feeling well and can’t make it to it to the bathroom or generally have a hard time making it to the toilet during the night you can place the commode next to your bed as a convenient solution during the night, then move it to the bathroom during the day. The commode is also a more permanent solution for someone that is bedridden for a longer period of time. 

Drive Medical Heavy Duty Bariatric Folding Commode, Gray All of the choices on our list have removable waste pots– which gives you the convenience of the waste going directly into the flush toilet with no need to clean the pot.  The commode chairs that made our list are also all designed to withstand heavy weight (over 400 lbs. with some are even rated up to 600+).

The Heavy Duty Bariatric Folding Commode by Drive Medical is a very solid option, and we suggest you take a look at it if you’re in a hurry to make a purchase. If you’d rather see us break down the attributes of different products and make a decision yourself, read on!

What to consider:

Sturdiness: Given the fact that these commodes will have to put up with a big amount of weight, their sturdiness will define just how effective they are. An ideal commode isn’t too difficult to handle and carry around, but it has to be sturdy enough in order to not fall apart when the user applies pressure on the product.

Ease of use: People with obesity issues need to have a specialized product that allows them to handle it with ease. Even if they aren’t the ones to assemble it or remove certain parts for convenience, the product needs to be easy to use in order to facilitate the caretaker’s responsibilities.

Toilet compatibility: A lot of commode owners would rather us it over their own toilet instead of the pot that the commode itself has, while also taking full advantage of the product’s features. In order to make this work, the commode has to have the ability to remove its portable toilet bucket and a comfortable design to make it fit above any regular sized toilet.

Removable Pot: all the options we selected can be used directly over your standard toilet so that waste goes directly in the toilet bowl, not in the removable pot, this adds a lot of conveniences and is more hygienic. The pot can still be used if you wish or at night when you need the chair closer to your bed.

Bedside Commode Chair by Duro-Med:

Duro-Med Portable Toilet, Bedside Commode Chair, Heavy-Duty Steel Commode Toilet Chair, Toilet Safety Frame, Medical Commode This commode chair by Duro-Med can hold up to 500 lbs. without hindering its performance, and it has a sturdy structure made of hard plastic that’s complemented by a design capable of adapting to the needs of a large adult.

The commode’s height can also be adjusted depending on the situation, which is an incredibly convenient feature for its users. This helps the product move closer to regular toilet seats while also allowing it to gain height beforehand in order to properly accommodate the user.

The product allows for the removal of its portable toilet and it can be placed on top of most regular-sized toilets with ease, making it a trustworthy ally even while traveling. It also comes fully assembled and ready to use!


  • Most owners should find it very comfortable and easy to use.

The frame can be easily snapped together thanks to its sturdiness, an essential feature to a product that can be armed and disarmed.

Although the commode itself is pretty wide and holds a lot of weight, the main issue this product has is related to the size of the pot. It seems to be a bit small, considering the overall size of the average user. It could be inconvenient at times.


  • It has a sturdy designed and a properly assembled frame, which prevents owners from slipping or falling over.
  • It can be used as toilet safety thanks to its ability to be easily reassembled.
  • It’s wider than most other commodes, which helps larger users feel more comfortable.


  • The toilet seat and its cover could feel very flimsy when used. It could cause some unfortunate incidents if the user isn’t careful.

  • Elderly patients could have some trouble moving it around.

Heavy Duty Bariatric Folding Commode by Drive Medical:

Drive Medical Heavy Duty Bariatric Folding Commode, Gray Unlike the other two commodes that we just reviewed, this one by Drive Medical doesn’t come pre-assembled but it rather offers a simple tool to do so, which could be done without using additional tools. It can also hold up to 650 lbs., making it an ideal purchase even for the morbidly obese.

It’s a very big commode, and it can be used as toilet safety (its pot can be manually removed), but be sure you have enough room in your bathroom in order to do so. It also comes with a splash guard that can save users the trouble of cleaning up unnecessary messes.

The fact that the product doesn’t include any clear assembly instructions could be an issue for some owners, as arming the commode could prove to be a challenge. In any case, once it’s assembled and good to go, the user should be pleased with their purchase.


  • Very large chair, capable of holding up an enormous amount of weight.
  • It’s easy to use and provides non-slipping safety to the user.

Final Verdict:

Heavy duty bariatric chairs help improve the quality-of-life of heavy persons in need of a more comfortable and manageable toilet for their weight and size. After going over each product in this article, we feel that the Heavy Duty Bariatric Folding Commode by Drive Medical offers the best attributes to make it one of the top-rated choices in the market, while also keeping an affordable price. It should make the user feel very comfortable when using it, be it as a toilet safety build or as a standalone portable toilet on its own.

The options from Duro-Med and Vive Health are also among the top consumer commodes we could find and either of these seems to deliver a quality home option. 

As mentioned, these bedside commodes can be a very convenient and versatile solution since they are portable and can be moved to and from the bathroom to the bedside depending on your daily needs.

Another often overlooked issues are if you have smaller sized people in your home, they may not want the XL toilet seat installed as they can actually be uncomfortable for small/skinny people- the hole is too large for them and doesn’t support their butt cheeks when they sit on it. This can cause some conflict in a home where you are sharing the bathroom and the portable commode can be a very practical compromise for everyone.
