(The box packaging) It's for a gift. Does someone have an image they can share, please?** A: It comes in a brown cardboard box. The pillow is squished into a plastic bag. You must wrestle the pillow from the bag and allow to sit and fluff up. My advice- buy something else. This was gifted to me on Monday. Under 140 pounds, sat on it for 5 minutes. The pillow was flat and I could feel my tailbone touching the seat through the hole in the cushion. They do not provide an invoice, packing slip, info on how to return or who this was a gift from. I emailed twice- no reply. Rcvd a c/b a few minutes ago but they can’t find any info for my pillow. I sure how to return. This item is way too expensive for what it is and it doesn’t do what it says. I am so appreciative to be thought of and that someone is willing to spend this much on a special pillow to help me but this pillow is a fail. I was sent the seat cushion and lumbar pillow. The lumbar pillow hasn’t really been tested much (I’m not over the moon about it). **Q: How is the seat cushion for bigger people, 6'6" around 380 lbs? Will it hold?** A: I am in a similar category - 6'5' ~ 350 lbs -- I did not like it -- it is too small -- it hits my legs in the wrong place -- and ( for my liking ) is NOT wide enough ....it requires constant adjustment to remain comfortable **Q: The photo says 16x16x3, the description says 15.5 x 18 x 4 inches. Which one is correct?** A: I found the dimensions for standard and large sizes per the manufacturer: Standard: 18 W x 15.5 L x 4 H inches Large: 21 W x 18 L x 5 H inches **Q: Has anyone tried it on a couch? i’m in my 70s and finding i have lower back pain after i’ve been sitting on the couch. hard chairs are fine** A: I have 5 lumbar (& 5 cervical) vertebrae which are messed up in multiple ways. I’ve found a good lumbar support cushion helps more than a seat cushion support. That said, it doesn’t matter how many different types of lumbar supports (with or without a seat support—I have tried many), that I try or use, if the chair or couch I am sitting in has lost its firmness/support, or was just too soft and not well-supporting to begin with, I will still have pain—even with the addition of constant heating pad use. I had a very nice Lay-Z-Boy recliner (though I never use the “recline” feature—it is more comfortable for me to have a rocking recliner and use an ottoman so I can keep my knees bent, and provide more relief of my lower back at the correct angle for me). When my back pain got considerably worse, my recliner was about 6 years old. I paid several hundred dollars for a Laz-y-Boy repair man to reinforce/replace the springs in it and replace the foam cushions. That, plus a lumbar support pillow and heating pad, kept the recliner usable for me for about another 4 years. Then, I decided to just buy a new one. I bought another Lay-Z-Boy, but still use a lumbar support pillow (one that goes as high up on my back as I could find: 17 inches), & of course, a heating pad about 80% of the time. I found trying to use a seat support on my new chair caused me to sit too high in it, and all the support it provided was hitting me wrong. I guess my point is: these types of supports can definitely help (depending on how severe your spinal problems are), or enable you to extend the life of a chair you like, but at some point, you may need to upgrade whatever you’re sitting in, and shop with back support as your top priority. Also, just like with mattresses: stay away from “all memory foam” construction. It breaks down over time and becomes a spongy mess. Look for good old fashioned firm spring support, though it is usually more expensive. You can always buy a memory foam topper for it—and when it becomes flat, just replace that! ## Frequently Bought Together - C CUSHION LAB Patented Pressure Relief Seat Cushion for Long Sitting Hours on Office/Home Chair, Car, Wheelchair - Extra-Dense Memory Foam for Hip, Tailbone, Coccyx, Sciatica - Light Grey - C CUSHION LAB Extra Dense Lumbar Pillow - Patented Ergonomic Multi-Region Firm Back Support for Lower Back Pain Relief - Lumbar Support Cushion with Strap for Office Chair, Car, Sofa, Plane - Grey - C CUSHION LAB Ergonomic Foot Rest for Under Desk - Patented Massage Ridge Design Memory Foam Foot Stool Pillow for Work, Home, Gaming, Computer, Office Chair - Footrest for Back & Hip Pain Relief --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/357078616-c-cushion-lab-patented-pressure-relief-seat-cushion-for-long](https://www.desertcart.tn/products/357078616-c-cushion-lab-patented-pressure-relief-seat-cushion-for-long) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-11*
