--- title: "Floor Cushion Stuffing: Does Silicone Ball Fill Flatten?" url: "https://cushionguide.com/answers/does-silicone-ball-stuffing-flatten/" section: "The Cutting Table" author: "Nate Kowalski, The Pattern Engineer of Detroit" author_url: "https://cushionguide.com/masters/nate/" published: "2026-04-10" updated: "2026-04-10" keywords: "floor cushion stuffing flatten, silicone ball filling, silicone fiber floor cushion, floor cushion filling, does floor cushion fill compress" --- # Will the silicone ball stuffing in a floor cushion flatten over time? *Short version: the fill is overpacked on purpose. The longer version comes with a weight, a length and one thing that isn't a bead.* Also asked as: How well does the stuffing hold up?; Will it compress over time? > **The quick answer:** Silicone ball stuffing is packed too densely to flatten: the workshop puts about 18-22 lb (8-10 kg) of fill into a 60 in (152 cm) floor cushion, and calls collapse practically impossible. The fill is soft fiber clusters that feel like cotton, not hard bean-bag beads, and it's sturdy enough that buyers sleep on the linen floor mattresses. ![Dusty pink corduroy corner floor cushion under a cream canopy with star, flower and cloud pillows, bunny, medallion rug](https://cushionguide.com/media/corner-floor-cushions/dusty-pink-corduroy-corner-floor-cushion-window-1536.webp "Tone-on-tone pink, from gusset to flower pillow to botanical prints, gives this corner a soft, finished look.") ## Key facts - Floor cushions are overfilled on purpose so they don't collapse. - A 60 in (152 cm) cushion takes about 18-22 lb (8-10 kg) of filling. - Silicone balls are soft fiber clusters that feel like cotton, not beads. - Bean-bag bead filling is not offered. - The fill is sturdy rather than slippery. - Buyers use the linen floor mattresses as beds. - Cotton filling is available on request. - Tufted floor cushions packed with silicone ball fiber are normally 4 to 5 in (10 to 12 cm) thick. ## Why 18-22 lb of fill keeps a floor cushion from flattening Flattening is a slack problem. A cushion sags when the fill inside has room to settle, so the workshop leaves it no room: about 18-22 lb (8-10 kg) of filling goes into a 60 in (152 cm) [floor cushion](https://cushionguide.com/cushions/floor-cushions/). That is overfilling by design, partner, and it's why the shop calls a flat cushion practically impossible after years of use. "Silicone ball" sounds like a bead. It isn't. It's a mass of small [fiber clusters](https://cushionguide.com/glossary/#cluster-fiber) that feels like cotton when you squeeze a corner. How many hours a day will yours be sat on? ## Silicone ball fill next to the other options | Fill | What it is | Offered | |---|---|---| | Silicone ball fill | Soft fiber clusters; sturdy, not slippery | Standard, about 18-22 lb (8-10 kg) per 60 in cushion | | Cotton filling | Natural fiber alternative | On request | | Bean-bag beads | Hard beads | Not offered | ## Sat on all day, slept on all night The fill is described as sturdy rather than slippery, which matters when the cushion is a bed.

The filling is a mass of soft silicone fiber clusters that feels like cotton. About 18-22 lb (8-10 kg) goes into a 60 in cushion, and the shop says it's practically impossible for it to compress flat. **A common question:** What are the linen floor mattresses filled with, and can we sleep on them? **The workshop's answer:** Silicone balls, which is silicone fiber. The fill is sturdy rather than slippery, and buyers use the cushions as beds. Cotton filling is available on request. **A common question:** Can I get a softer, plusher cushion instead of firm foam? **The workshop's answer:** Yes. Ask for 28-density foam instead of the standard 32 for a plusher, slightly sink-in feel, or add a 3/4 in (2 cm) wadding layer. Feather-wrapped foam isn't offered. ## Questions buyers ask next ### How much filling is in a large floor cushion? About 18-22 lb (8-10 kg) of silicone fiber clusters in a 60 in (152 cm) cushion. The workshop overfills on purpose, so that weight is part of what keeps the cushion from collapsing over the years. ### Does silicone ball fill shift around inside the cover? It's described as sturdy rather than slippery. The fiber clusters sit together as one dense mass, which is why the linen floor mattresses work as beds as well as seats. ### Is there a natural alternative to silicone fiber fill? Yes. Cotton filling is available on request for floor cushions. Silicone fiber clusters are the standard fill, so mention cotton in your order note before the cushion is made. ## Related at the atelier - [What is silicone ball filling made of?
