She is 215 an it works great for her. She sits back to tub, spins seat slides over into tub, washes slides back out of tub, twist away from tub and done! I think it was a little expensive, but well worth her comfortWe have used the swivel style sliding bench for many years. We needed to replace it so we opted for this style with the replaceable cutout. The only thing different from the regular swivel sliding bench is that to accommodate the cutout, the seat is about 2-3 inches taller for us even at the lowest adjustments. For those who are considering this model you need to take that into consideration. If the person showering has short legs or is short, the seat is higher to get onto and when in the bathtub, a stepstool will be needed under their feet. (We have used a hard plastic foot stool we bought at Walmart for less than $10 to put under his feet while in the tub.). One benefit of the seat being higher is that it is easier to lift their feet over the edge of the tub. And I don't have to bend over as far to help with washing. So there are pluses and minuses to this seat model. I am dealing with my adult son with CP in this showering/bathing process so I am the one making the accommodations and assistance. For us, this model still worked well for us but as I have indicated it is different in height from the regular swivel model. But either way, I have to tranfer assist him onto the seat, push it into position,and pull it back each time we use it. This seat swivels and slides easily so we are pleased. The cutout will be useful when cleaning between the legs is necessary and there is space to easily access between the legs (because of the height of the seat). The space is adequate and similar to a separated toilet seat being open in the front. The cutout lifts out easily and stays in place when in position....though not tight.I bought this for my elderly in-laws to use. One has dementia and the other is in poor physical health. Bath/Shower time is SCARY...Both have said this bench has made them both feel so much safer and they are SO HAPPY with this bench. HIGHLY RECOMMEND!Well, sadly, the Transfer Bench with Cut-Out Molded Swivel Seat / Back was less than successful. In fact, I want to return it. I mean, if you spend that much money, you want perfect.1) For someone with MS and cognitive issues, like me, or maybe someone with Alzheimer's - instructions on how to use it need to be posted in the bathroom. To slide left, press the red lever on the right down. To slide right, etc. But that's on me. Not a fault of the product.2) HUGE issue: it's too high off the ground. It's on its lowest position and I am 5'8" and my feet are on tippy toes on the ground. It's scary. Don't tell me to use the seat belt, I need to be able to move to pick up things I drop. The seatbelt is useless for me because I always drop stuff - my hands don't work very well. Like soap, washrag, shampoo - over and over. And bending over to pick them up, causing my weight to be centered around my head and sitting that high up - well, that's scary. I felt like I was going to topple off the chair, headfirst. People who don't have balance issues probably won't understand that.3) The floor was soaked. We haven't tried a split curtain yet (sold separately) to see if that alleviates that - and now we probably won't. But this meant that I couldn't get dressed while sitting on the toilet because the bottom of my sweats and socks would be soaked. So I had to transfer, naked, onto my wheelchair in order to get dressed. And if you've ever sat, skin to plastic, while you were damp, you know how your skin sticks to the plastic. Getting up to my feet (which is hard enough as it is) and having to peel my skin off that plastic (to pull up my sweats)…well, it hurt.4) I couldn't dry my feet off because, again, I was unsteady on the chair. Which didn't matter anyway because the floor was soaked, making it scary to transfer on wet tile to my wheelchair.Those four issues could be solved if you aren't bathing yourself, if you have a caregiver to aid you. Which I don't. I shower myself. But there is a number five.5) The BIGGEST COMPLAINT is that the seat is SO uncomfortable. I had the part out so I could wash my privates and my butt cheek kept falling into that hole - and I couldn't reach the ground to readjust! And that feature (the removable part) was a huge selling point for me! My butt STILL hurts from that uncomfortable seat.The shower chair was way more comfortable and yea, transferring to it is tricky because I have to sit on the edge of the tub to get in it, but I felt safer with my feet firmly on the ground.We tried other types of sliding benches, but this is the one that PERFECTLY fit"s our needs. The in home care givers for my 89 year old Mother in Law raved about this bench.This biggest advantage is the sliding swivel seat. The swivel seat allows someone to migrate from a wheelchair or lift on to the bench without much effort whatsoever.This product was easy to assemble, seems very sturdy, and appears to be a quality made product.I highly recommend this product. A few folks in her senior neighborhood are now looking at this product to purchase.
