Memory Foam Car Seat Cushion and 3D Mesh Lumbar Support Pillow, Coccyx Orthopedic Seat Cushion for Office Chair Lumbar Support Back Pillow Black

I bought this set just under 4 months ago and have been using it with a dining chair while working from home following a prostate operation. I have issues with both parts of this set;- The Seat is thin and after as little as an hour it becomes flattened and uncomfortable to the extent that it does not offer any support- The back rest started off well, but after only a week or so, the straps that tighten around the back of the chair no longer hold it in place so it drops to the bottom of the chair and requires constant adjusting.I now use a spare pillow which is much more comfortable. Very disappointed!

This is a lovely cushion, but I noticed a problem with it because of the design with the gap where your sacrum rests (and this applies to all similar cushions, not just this brand).This cushion is GREAT if you have it on a completely flat seat. However, if the seat you are on has slightly curved edges up, like on many office or gaming chairs, then take care with this. The gap in the middle of th cushion allows it to bend in a way that a solid cushion doesn't with the net effect that it was actually compressing my pelvis centrally slightly.A few days after using this cushion on an office chair with slightly curved upwards edges, I noticed that I was getting a lot more sacro-iliac joint pain than normal (my spine is not great!). It was only after I realised that this correlated with using the cushion that I switched this to a different, flat seat... and my pain disappeared when using it. I say this with some authority as I am an Osteopath.So, it's a great cushion, but if you have sacro-iliac (SI) joint problems, then make sure you only use this on a completely flat seat.

I think the pictures are misleading for this product. The seat in the pictures looks thick and appears as if it would support a person’s weight but mine feels incredibly thing as if it’s missing the filling. Because it feels like this, my tailbone which is experiencing pain is still pressed down on my desk chair and also the sofa.The back support is adequate, but I don’t believe the price is justified and if you are going to be choosing something like this to alleviate pain, I would recommend buying in person somewhere so you can see what the quality is.

Overall disappointed, fairly expensive for a bit of shaped foam, but reviews good so thought I would try. Had product less than 24hrs before the plastic clip that holds the lumber into place broke. The lumber cushion is comfy but flattens a bit much over time to stay supportive. The seat cushion could be a bit tougher too, it’s not the largest area to sit on, and also flattens out during use. Given clip is already broke, I don’t expect this item to wear well. Can’t hold it securely in place, and other clip will break with the pressure. All very disappointing for the price.

The sponge material in this product is too weak to be effective.I weigh about 15.5 stone, as an average height (5'10"), slightly overweight man.this foam filled shaped bag, really doesnt cut the mustard.firstly the seat part squashes down and loses robustness, before long you have flattened it out to a pancake, child booster seats in cars have more rigidity and theyre only intended for toddlers.the surface area too, suitable for a slim lady, but only really sits in the center of a standard office chair leaving a couple of inches each way, including front and back for you to perch on. but thats fine when is squishes down it gains an extra inch all round. however on a leather chair, this will tend to slide to one side or the other, which I suspect you subconsciously correct wit your spine...so that cannot be good!the backrest (lumbar support), without weight crushing it pushes you 4 inches forward, off the tiny butt perch the bottom seat has provided, so you no longer sat on the chair. you can correct this by swapping them around and crushing the lumbar to a pancake, before putting them back in their original positions.once again, Amazon have turned into wish, it looks like it is what you want, but it aint! its some cheap nasty piece of rubbish! I blame brexit!

This product was delivered next day and came rolled up. After taking out of pack it took its shape within a short space of time although I left it overnight. The material is nice and soft. As I am working at home my posture is suffering and my back was beginning to ache quite severely. The first day was a trial and error day and I found I was aching in another part of my back. After the second day my back stopped aching and I managed almost a whole working day in my seat. The seat cushion is very comfortable and although it raises the seat a little this can be lowered to achieve the correct height. The back cushion makes you sit properly. I found that if i sit closer to the desk edge and have the computer closer it is the ideal position. I wish I had bought this earlier and saved myself some pain and discomfort.

When I put these cushions onto my car seat I thought there would be no room for me too! However, when I got into the car, the memory foam squishes down so that they just take up the amount of room you need. Finally I can see the front of my car and they make driving much more comfortable over all.

No support especially in seat area. Cushion squashed to hardly anything and I am not heavy!!
