But if you have a simba pillow and need more, this is a godsend! ### ⭐⭐⭐⭐⭐ Blu Cubes... *by R***E on 30 April 2026* I got my Simba pillow over a year ago and have been getting an achy neck and shoulders lately, im thinking my pillow was a bit too soft,i was really thinking of getting a new pillow but saw the Simba Blue Cubes got one bag two days ago put three big hand fulls into my pillow slept on it,three was too much so tookout a hand full,two was good for me it doesnt seem like a lot but its perked up my pillow and is more comfortable,will keep my spare cubes incase i need to replace some in the future... ### ⭐⭐⭐⭐ Perfect for adding more support for side-sleepers *by C***. on 13 January 2023* I have added a photo of the bag you get as nobody has posted an image yet and it's hard to know from the product description how many nanocubes you actually get. Basically they send you the bag they include with the hybrid pillow filled with nanocubes, so about 6 handfuls of Nanocubes. I thought I was going to have to return the pillow or complain to them if after spending 8 pounds on these they still didn't add sufficient support for a side-sleeper despite the pillow costing 100 pounds. But I'm happy to confirm there is a substantial difference in the firmness of the pillow after adding two extra bags. I originally felt my head sinking into the middle of the pillow as the pillow went flat, but with two extra bags of Nanocubes, there is significantly better support and I no longer find myself sinking. It makes the pillow feel more like a memory foam pillow due to the extra firmness and less like a down pillow that feels soft but lacks any neck support. It might be best to buy one bag, as it's free shipping, and see how that goes as I did find one bag did make a big difference, however, I ultimately had to order a second bag and found that two bags offered me the most ideal support. I knocked a star as I believe that, considering the premium price of the pillow, Simba should be filling up the empty bag that comes with the Hybrid Pillow instead of giving us an empty bag because the pillow is advertised for side-sleeps but just isn't suited to a side-sleeper without paying an extra 8 pounds for what is effectively an identical bag they include with the pillow but filled with Nanocubes. Fortunately it's unlikely that most people will need any more than one bag unless you want a very firm pillow that would eliminate its softness. Contrary to what some reviewers said, the Nanocubes are exactly the same size as the Nanocubes that came with the pillow. The reviewers who complained may have a much older pillow with different sized cubes that they no longer use with the more recently produced hybrid pillows as my pillow was purchased on 1st January 2023 and the cubes appear to be identically sized. ## Frequently Bought Together - Simba Extra Nanocubes Bag - Simba Hybrid® Pillow, with Temperature regulating Stratos technology & Customisable height (45 x 70cm) - Extra Large Pillow Case Pair "22 x 31" / White Pillowcases / Percale Pillowcases (White) --- ## 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.us/products/188954740-extra-nanocubes-refill-bag-100g-hybrid-pillow-foam-pillow-filling](https://www.desertcart.us/products/188954740-extra-nanocubes-refill-bag-100g-hybrid-pillow-foam-pillow-filling) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-07*
