Honestly - a Murphy bed setup is much more comfortable if you can get past the old Muppet movie tenement scene jokes. More on reddit.com

ISO chairs. They are larger in size and have hydraulics to convert to a chaos and then a full size twin. Twin sheets fit them and a twin duvet. Although I wouldn't recommend them for month long stays, they are great to enable an extra guest for the weekend. Works best for kids or young adults. They are over $1000 but worth every penny . https://www.homequarters.ca/products/iso-mobital-fabric-sleeper-chair?variant=45740528894249¤cy=CAD&utm_medium=product_sync&utm_source=google&utm_content=sag_organic&utm_campaign=sag_organic&gad_source=1&gclid=CjwKCAjw7-SvBhB6EiwAwYdCAVgM04UJy6CgJteFHduAaoRIx08YvuQa2v_XmhuGCiQxpnwmGFzjKBoComkQAvD_BwE More on reddit.com

This is such an American problem. I have to tell you, the choices for sleeper sofas is amazing in Scandinavia and other parts of Europe. You may want to look into whether you can find a Scandinavian design furniture store near you or try and order (although this could be expensive).

your best option for an application in which you will actually use the bed more than 1 or 2 days a year: American Leather. its a widely held opinion within the furniture industry that these are the best BEDS in sleepers The design is patented and/or protected by aggressively litigious lawyers, and the result is zero competition and so a VERY high price tag. WARNING: American Leather sofas are stupefyingly heavy.... This is not an exaggeration. They weigh around 200-250 lbs. No joke. That makes them as much as 100 lbs heavier than some of the really light weight sleeper sofas. If you get an American Leather sofa, you will 100% need to have 2 legitimately strong guys move it. Its very hard to spend less than $3,000 on an American Leather. The 2nd choice is the conventional bi-fold metal frame sleeper, which is the same basic design that everyone on planet earth is already familiar with (its almost 100 years old). The cheapest solution to make a bifold work for ergonomics is to buy a 2ndary ~3" foam topper that you store in the closet for when its needed. its clumsy but it will always work. The other solution is the Air mattress (Legett and Platt makes them). The problem with the air mattresses is that the air bladder and/or pump will, inevitably leak or break.... even if its in 5-10 years its almost guaranteed to happen. There is another bi-fold sleeper option that is less commonly availabe. its called the Cozy Mattress Sleeper ( http://cozymattress.com/ ) and a few smaller US based furniture manufacturers offer them. They are spring mattresses and are ~8-9" thick (which is about 2x the thickness of a conventional bi-fold sleeper). They are thick enough so that you have zero chance of feeling the middle bar or anything like that. They are ultra heavy duty variants of the bi-fold that are designed and intended for use in "premium" commercial applications like high end hotels. ultra heavy duty means significantly thicker metal-tube frame construction, more springs, and the mechanism itself is spring loaded (which means opening and closing it is aided by a spring) for people 160lbs or less, I would say its "medium firm". I don't think anyone would describe them as "soft". For heavier people, in the 160-200lb range I think its still probably "medium firm" bordering on medium. Like the American Leather mentioned above, these sleepers are very very heavy. The retailers/manufacturers that I know that sell these: Flores Design Inc (a manufacturer with a bunch of retailers you can buy from, including Apt2b)Soft Goods (a custom manufacturer in LA)Delux Manufacturing Concepts (a custom manufacturer in LA)Furniture Envy (A custom retailer in San Francisco)California Sofa (a custom retailer in Marin County) SOMETHING TO KEEP IN MIND: All bi-folds are short-length queens. The standard bi-fold found everywhere is 72". This sometimes called a "short queen" or "RV size". The Cozy mattress Sleeper mentioned above is around ~74"-~75" American Leather mattresses are full 80" length queens. Bifolds are generally not available as king size. Even the small number of exceptions are still limited in length. American Leather DOES make kings. DO NOT under any circumstances consider any of the following: Click clacks (where the backrest folds down) anything with a fixed/built in seating area (common trundle beds) anything that is too unique or specialized or proprietary More on reddit.com
