DIY floor sofa mattress covers are what turn them into a sofa.* Also asked as: Covers for my own mattresses?; I'm creating my own teddy floor sofa. > **The quick answer:** Yes: empty covers can be sewn to fit your own floor sofa mattresses, with matching L-shaped backrests. Write each mattress size in the order notes. Two 75 x 35 in (190 x 90 cm) mattresses were paired with 35 x 37 in (90 x 95 cm) backrests. Backrests come as covers only or filled, and filling costs extra. ![Crimson woven linen-look cushion on a white IKEA Hemnes daybed, cream piping and matching round bolsters](https://cushionguide.com/media/ikea-hemnes-daybed-covers/crimson-hemnes-daybed-cushion-cream-piping-bolsters-1600.webp "A low angle along the daybed shows the cream piping drawing one clean line from the bolster to the far end of the mattress.") ## Key facts - Empty covers are sewn to fit mattresses you already own. - Mattress sizes go in the order notes. - Two 75 x 35 in (190 x 90 cm) mattresses were paired with 35 x 37 in (90 x 95 cm) L-shaped backrest covers. - Backrests can be ordered as covers only or filled. - Filling the backrests costs extra. - Unfilled mattress covers with filled backrests go through a custom option on the daybed cover listing. ## Your checklist before the teddy is cut - ✓ Measure each mattress: length, width and thickness, such as 75 x 35 x 10 in. - ✓ Write every size in the order notes, not only in a chat message. - ✓ Count your backrests: two mattresses took two L-shaped backs. - ✓ Choose covers-only backrests or filled ones; filling is charged extra. - ✓ Keep one teddy color for every piece so the sofa reads as one shape. - ✓ For empty mattress covers with filled backrests, ask for the custom option on the daybed cover listing. ## Why the backrest is sized from the mattress A floor sofa is a mattress wearing a good coat. When a buyer wrote to the workshop about building one from two 75 x 35 in mattresses, the workshop sized the backrests from them: two L-shaped backs at 35 x 37 in, each as wide as a mattress, so the seams fall in line. Teddy suits a homemade base. Its deep, soft pile in oat, cream or warm caramel makes two plain mattresses look like furniture.

What do your mattresses measure, my friends, once the tape is laid flat? ## Tufting, snug backrests, full sets: three assumptions to drop - ✗ Tufting on a zippered cover: tufted floor cushions are stitched closed after filling, so made-to-fit covers stay plain. - ✗ A snug fit for another maker's backrest: in covers cut to standard sizes, it may sit slightly loose. - ✗ A whole new set when one cover fails: single base, backrest, corner and armrest covers are sold on their own. > **Tailor's margin:** DIY floor sofa covers start with the mattress itself: length, width and thickness of each one, like 75 x 35 x 10 in, written in the order notes. > Two 75 x 35 in mattresses become a teddy floor sofa with two L-shaped backrests at 35 x 37 in, sewn as empty covers or filled for an extra charge. > > — Élodie Marchand ## Buyer questions **A common question:** I'm putting together my own floor sofa. Could you sew covers for my mattresses and the backrests too? **The workshop's answer:** Yes. For two 75 x 35 in (190 x 90 cm) mattresses, the workshop suggested L-shaped backrest covers at 35 x 37 in (90 x 95 cm). Covers only is the base option; filling the backrests is extra. **A common question:** My mattresses are 10 x 35 x 75 in. Can I have empty covers for them but filled teddy backrests? **The workshop's answer:** Yes. Two unfilled mattress covers and two filled teddy backrests were set up as one order through a custom option on the daybed cover listing. **A common question:** Will your replacement covers fit a teddy floor sofa from another maker? **The workshop's answer:** Usually, if the sizes match: seats of 79 x 39 x 6.7 in (200 x 100 x 17 cm) and L-backrests of 39 x 39 x 15.4 in (100 x 100 x 39 cm). Check each piece's height. ## Questions buyers ask next ### Can a made-to-fit mattress cover handle an in-between thickness? Yes. Covers follow the thickness you give, and odd sizes such as 5.5 in (14 cm) are fine. Write length, width and thickness for every mattress, with your fabric code. ### Can the covers for my own mattresses be tufted like the ready-made floor sofas? No. Tufted floor cushions are hand-stitched closed after filling, so they have no zipper. Covers for your own mattresses are plain and zippered, which is what lets them come off. ### Do mattresses of different sizes need separate orders? Yes: one order per size, with the exact length, width, thickness and fabric code in the personalization box. Mixed sets, like empty covers with filled backrests, use the custom option instead. ## Related at the atelier - [Will your replacement covers fit a teddy floor sofa from another brand?](https://cushionguide.com/answers/teddy-sofa-covers-fit-other-brands/): Teddy sofa replacement covers usually fit another brand's sofa when the dimensions match: seats of 78 x 39 x 6.5 in (200 x 100 x 17 cm) and L-shaped backrests of 39 x 39 x 15 in (100 x 100 x 39 cm)… - [What's in the covers-only set, and what size are the covers?](https://cushionguide.com/answers/floor-sofa-covers-only-set-dimensions/): A covers-only set dresses one single floor sofa with four zippered covers: two seat covers of 78 x 39 x 6.5 in (200 x 100 x 17 cm) and two L-shaped backrest covers of 39 x 39 x 15 in (100 x 100 x 39… - [Will your covers fit a floor sofa I bought from another brand?](https://cushionguide.com/answers/replacement-covers-fit-other-brand-floor-sofa/): Standard-size replacement covers often fit a teddy floor sofa from another brand, and owners of the original designer model reported no measurement issues. - [Custom Cushion Cover in Forest Green Bouclé, Hidden Side Zipper](https://cushionguide.com/readings/forest-green-boucle-cover-hidden-side-zip/): A bouclé cushion cover can hide its zipper completely when the zipper sits in the seam of the side boxing strip: once closed, the loops lean over the tape and the front reads seamless. - [Custom Cushion Covers in Raspberry, Mustard and Green Tweed](https://cushionguide.com/readings/raspberry-mustard-green-tweed-cushion-covers-stacked/): Custom cushion covers can be ordered on their own, made to the length, depth and thickness of the foam you already have. - [Custom Cushion Covers in Five Velvets: A Pairing for Each Season](https://cushionguide.com/readings/five-velvet-cushions-fanned-oak-floor-piping/): Custom cushion covers let one cushion change with the seasons: zip off an ivory velvet with gray piping for summer and zip on emerald with coral piping for the holidays. - [Replacement covers for a floor sofa: fit, color change and single pieces](https://cushionguide.com/guides/floor-sofa-replacement-covers/) - [Ordering new cushion covers for foam you already own](https://cushionguide.com/guides/cushion-covers-for-existing-foam/) *With color and care — Élodie* --- Written by Élodie Marchand (https://cushionguide.com/masters/elodie/) for CushionGuide (https://cushionguide.com/about/).
