Suprise!!!
So, I was a bit skeptical about buying a hunk of memory foam, for the price. But this cushion not only provides support, but it is also comfortable and really helps alleviate pain from an old injury. I play games online as well as banking and surfing. Surprise!!! My legs aren't hurting. Maybe I found something specific to aiding my injury...who knows. I'm satisfied. Couple of things I noticed...memory foam holds heat, so sometimes it's a bit warm and the size of the cushions doesn't fit my office chair very well. But still a great product.

Easy to use, great support
I got these for my computer chair. Easy to use, soft, and retain their shape. I don't feel that it has a cooling effect, it's always warm in my opinion. Good quality memory foam, never flat, and is slip resistant. Easy to use, comfortable, and effective.

Makes me feel like I have a UTI.
I know that sounds really strange and is maybe really personal. But I have been using this butt cushion for about 5 months, and I know that it is the reason I feel this strange sensation. Firstly, I don't use the lumbar cushion because my chair is too small for it to strap on to. Secondly, I have good things to say about the butt cushion: 1. It really keeps its shape well. It is firm, and when left for multiple days (like a weekend or longer), you come back to a plump, firm, not-squished seat cushion. It is nice. 2. It feels comfortable, it really does. I actually really liked the hump that sits between my legs until I realized it was making my urethra uncomfortable. 3. The grips on the bottom!!!! They're awesome. It does not slide around. 4. The price is great. I bought this because my stool at work has a METAL BOTTOM, tiny surface area, and looks like it's from a torture chamber. I was very pleased with the quality for the price I paid. Until the discomfort began... So, somehow, the hump that exists in the middle that rests between the sitters legs pushes strangely on my nether regions and affects my urethra. I find myself feeling like I have to pee like all the time. Then, when I get up, it also still feels that way, and I experience a tad bit of discomfort even when urinating. The feeling lasts basically all day, even after I've left the seat cushion (on my drive home, for instance). It goes away in the evening and I never feel it on weekends. I tested out sitting in another chair at work all day and felt no discomfort. It's definitely this cushion. As soon as I sit down, now, I start to feel that strange sensation of needing to urinate, even if I just peed. I don't know if this matters, but I'm a plump, tall female. I have plenty of cushion on my legs and nethers already, so I can't imagine how a skinnier-than-I-am female could find this thing comfortable. I really want to like this thing because it does feel supportive and comfortable. But the uncomfortable feeling of needing to pee all day just isn't going to fly with me. I've ordered a new chair altogether.

Butt has never felt better
This was probably the best buy I could have gotten from a gaming perspective. Gaming chair is great and functional but after a few hours on your tush, you're going to want a pillow. This pillow delivers what your butt is asking for. The size is great, the quality and softness, gives relief from long gaming sessions.

Instant relief
TL;DR This product provided me immediate relief and for the price, I strongly recommend at least trying it out if you have back pain or sciatic pain while sitting in chairs. I've been struggling with bad back problems for the past two years since a car accident. Herniated discs, sciatica and other issues that haven't been completely diagnosed yet. I'm in my early 30's and never had back issues before so it hadn't occurred to me to buy products like this before. I spend a lot of my off-work hours sitting at a desk writing and playing games but for the last several months I've had to move my set up to use from bed because it hurt too much to sit up in my chair. After recovering from an injury, I attempt to sit back at my desk but the pain begins to increase again until another mistake that would cause my back to go back to square one. I bought this today as of this review, same day delivery and I got immediate relief upon setting this bad boy up. First time I've sat at my desk in years and it doesn't hurt - I feel like I can write again without the pain and discomfort causing me to lose much needed focus. I don't know how well or long this will hold up but 30 bucks for this immediate relief made this the best purchase I've done in ages. When I say immediate relief, I mean it. My lower back feels properly supported and my ass doesn't hurt like hell, and the pain radiating down to my legs quickly faded away. It is on the cheaper end so I'm not expecting this to last forever but its absolutely worth trying out to see if it helps you as well. This is also the first time I've bothered writing a review for a product before - that's how much this product impacted me just within the first few hours.

Perfect!!!
This is a great set for your 'tush' and lumbar support. I had ordered one set (different brand) which was a total disappointment... like sitting on a pancake or piece of cardboard and thus returned. I ordered the Fortem set during the 'Prime Days' and it truly is a much better quality that the other brand. Definitely providing pain relief and lumbar support. Seems to be the perfect design, shape and firmness. The memory foam seems to be a great quality. Ordered primarily for the car and the fit seems to be perfect... the next 'long' drive will tell the story!

Paso muchas horas en mi mesa de modelismo, a veces en una postura muy estática y encorvada ("postura de gamba") para pintar detalles. Mi silla de taller es básica y dura, y acababa con dolor de coxis y lumbares. En lugar de comprar una silla nueva cara, decidí probar este kit de FORTEM para "tunear" la que ya tenía. Lo que me ha gustado (Ergonomía real): -El cojín de asiento (Forma de U): Esto es lo mejor. Tiene un recorte en la parte trasera para que el coxis quede "flotando" y no apoye contra el asiento duro. Alivió la presión en la base de la columna casi al instante. La espuma es densa, no se aplasta hasta tocar la madera en cuanto te sientas. -El respaldo lumbar: Te obliga físicamente a sentarte recto. Si intentas escurrirte en la silla, el cojín te empuja. Para trabajos de precisión donde necesitas estabilidad, ayuda a mantener la espalda alineada. Lo que debes tener en cuenta (Cambio de geometría): Aumenta tu altura: El cojín levanta unos 5-7 cm. Ojo con esto: -Tendrás que bajar el pistón de tu silla. -Si tu silla no baja más, puede que tus rodillas choquen con la mesa o cajonera. Mídelo antes. -Calor: Es espuma viscoelástica (Memory Foam). En invierno es una gozada, pero en verano da calor. Es el precio a pagar por la comodidad. Consejo de Mantenimiento: -Fundas lavables: Como en el taller hay polvo de lijado y suciedad, agradezco que las fundas tengan cremallera y se puedan meter a la lavadora. El terciopelo atrapa el polvo, así que hay que lavarlas a menudo. Conclusión: Es la actualización más barata y efectiva para tu salud si pasas horas sentado. Por una fracción de lo que cuesta una silla "Gaming" o ergonómica, conviertes tu silla vieja en un trono cómodo. Mis sesiones de pintura de 4 horas ahora son mucho más llevaderas.

The FORTEM seat and lumbar cushion set is a game‑changer for anyone sitting long hours at a desk or in the car. The memory foam is dense yet soft, providing the perfect balance of comfort and support. It helps maintain good posture and has relieved a lot of my lower back tension after just a few days of use. The non‑slip bottom keeps the cushions securely in place, and the adjustable strap on the back pillow fits easily to different chair sizes. The breathable, washable covers are another big plus—they keep everything fresh and clean. Whether for working from home, gaming, or driving long distances, this set makes a huge difference in comfort. Excellent quality, ergonomic design, and good value for money.
