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.

Good, but not perfect
I bought this orthopedic chair for my grandfather. It’s not the best chair out there, but it does the job and provides decent support. It’s comfortable enough for daily use and seems fairly sturdy. Overall, it’s a good option for the price.

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.

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.

Fits my needs
I use the back for my chair at work all the time. The bottom isn't quite comfortable and is a little large to fit my particular chair but the cushion is great.

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.

Cuscino e supporto lombare per sedia da ufficio fatti molto bene. Arrivano sottovuoto e bisogna lasciare prendere la forma ai cuscini per almeno 5-6 ore prima di utilizzarli. Poi sono molto comodi e morbidi prendendo la forma della persona che utilizza la sedia abitualmente. Un buon prodotto che vale il prezzo pagato.
