Washable Self Skinned Support Wedge | Better Posture for Back Support | Sciatic Pain | Car Seat | Office Chair Pad, Meditation and Car Cushion (Medium Firm, 3.5 in)

This product is definitely firm and supportive, which is good to know with nearly every cushion out there being super soft memory foam that you sink into or causes it to flatten- which is super annoyingI have chronic pain and I need a wedge cushion for my car because of the slope of my seat causing strain on my upper body. I would be keeping the 3.5 inch one if it was a bit thinner, and I’m hoping to try a different size to see if it meets my needs in my small car. It was also a tad bit too firm, though I would think it will soften a little with time and would be more comfortable if it was the right height for my car’s seatEven though this particular product didn’t work out for me, wanted to mention in a review that it’s very supportive. Posture begins in the pelvis and it was much easier to rely on that and my core to sit upright and drive as opposed to straining my shoulders, neck, and jaw as I lean forward inn my seat where the bottom is sloping down where it meets the back. There was a little too much pressure on my piriformis muscles and sciatic nerve though, but I really want to try a shorter cushion that’s slightly softer from this brand!

I have chronic back pain and a full time desk job - a very bad mix. I have tried different chairs, positioning, added foot rests, back supports, without relief. I recently read about the benefits of using a wedge cushion on the seat of a chair. By doing so, it aligns your body so that the shoulders stack over the hips, relieving pain. I tried two other wedge cushions before I found the SITTS cushion. They were worthless as the cushions sank to almost nothing once I sat on them (for reference I am 5'3" and 115 lbs.) Then I found the SITTS cushion - it has made a remarkable difference in my comfort during a long day of sitting. I purchased the 4" cushion. I would suggest flipping this cushion to the "wrong" side as the "right" side has a hard edge along the top, which is where you sit. I also purchased the foam topper, which helped soften the cushion a bit, and made it less slippery. Deborah Lee has made a quality product that really works. I have called her for advice on cushions & the topper and she was very helpful and genuinely concerned that I would have the best experience with her product. One warning: do not use this cushion on a wheeled chair for a first time use. It takes some getting used to and the cushion itself is slippery.

For the price I would have thought a cover would have come with the cushion. I’ve only used it for the past week and it’s already showing signs of getting chewed up a bit.

I saw other reviews calling it “hard”, and it actually made me think that it was what I wanted. I wanted something that would hold me UP and not squish down, and this is PERFECT. It’s not hard though - it’s firm. I wanted this to meditate - my legs fall asleep so my body gives up before my mind does. I needed some help sitting up and elevating my behind and this is great. It’s my first day, and after using it an hour on the floor and two hours in a chair, my lower core is starting to feel tired. This is what they mean when they say it takes some time to adjust. I’m glad that it’s putting the work on the right muscles, and not my upper back and shoulders! (Which feel relaxed, for a change). My head is up and my neck is long, effortlessly.I don’t know what size I got: I guess the basic size? It doesn’t specify, not even in the packaging.I’m not paid or compensated in any way - this is just so perfect for my uses and I wanted to write the review that would have answered my questions when I was comparison shopping.

I bought this for my car, since I'm short and needed another 2 inches of height to see comfortable over the dash. I like this seat because it doesn't slip around on my leather seats, and it fits pretty well in the seat. The only negative is that it is QUITE firm. BUT that does mean that the 2.5 inch height is consistent.

These are made well, and come fast-- but harder than expected and has no kind of fabric or cover on it (so I made one)I can't use it, as it hurts my tailbone & lower back, but this may NOT be an issue for other people! (I have spinal damage from an injury)I think I'd use it if it weren't so dense/was slightly softer..... A bit pricey for a chunk of rubber....

Several things I deeply appreciate about this cushion. First, it works! I've been using mine for a little over a week and it's making a noticeable difference in my sciatic pain. I'm beyond grateful. Second, unlike most wedge cushions, this one is designed so the back of your legs aren't pressed into it. Third, it actually fits in my car seat so I can get the proper angle (knees below hips) when I drive. Fourth, it really is portable. Fifth, it's fairly firm (the others I tried were too soft/squishy) without being uncomfortable. Sixth, it comes in 3 different wedge heights. I ordered the 2.5" and just ordered a 3.25" and a 4" because different chairs have different angles. My back issues are degenerative, so this is part of my focus on postural correction to help minimize problems down the road. Thank you SITTS Perfect!!!UPDATE: It's now 2 1/2 years since I got my first Sitts Cushions. They are all 4 (yes 4!) of them going strong, including one that has been in my car 24/7 in heat and cold. They are as firm as they were when I got them. I can't recommend these enough if you have lower back or sciatic pain and need to upgrade how you sit, whether at home or in your car (and yes, it works perfect in my desk chair too.)

The 4" firm seat fits perfectly in the space of my kayak. It levels the seat and is awesome support for my Ocean Motion seat. Im not sure how waterproof it will be if it gets wet, but it seems to be solidly constructed. So comfy i bought two for my sons kayak.
