With a contemporary design and a bold red color, the Mainstays Metal Arm Futon is the perfect choice for small apartments, dorms, living rooms and guestrooms. With a simple adjustment, this futon transforms from sofa to bed.

After reviewing this Mainstays sofa sleeper for ourselves, we can’t help but recommend it. It’s so affordably priced, it’s comfortable, and it’s durable. These three things are the key most important factors to consider when buying a futon.

But before we dive into our detailed review, let’s take a quick look at the pros and cons of this model.


  • Attractive contemporary style
  • Includes mattress
  • Serves as couch or bed
  • Great for dorms, apartments, guest rooms and living rooms
  • Convenient low sitting frame
  • Affordably priced


  • Assembly is complicated

Our First Impressions

We loved the contemporary design of this futon. It’s modern. It’s sleek. And it boasts a bold red mattress. What more can we say? This futon will look great in any space.

With a compact design, this is an apartment size sofa bed that’s easy to move around. The entire Mainstays metal arm futon with mattress included weighs just 50 pounds. You’ll have no trouble moving or assembling this piece on your own.

The low sitting frame is convenient, it makes it easy to get on and off the futon. With one simple adjustment, you can transform this futon into a bed. If you’re living in a smaller space, this futon can do double duty as both a sofa and a bed.

It’s affordably priced, too, which is always welcomed.

The only issue we had with this model was that assembly was very complicated. The futon comes in two separate boxes, and both are quite heavy, so you may need help moving them into your home. The assembly process itself is very time-consuming, so expect to spend at least two hours putting this thing together.

Normally, this would be a major drawback for us, but because of this futon’s price point, we really couldn’t complain.

Mainstays Black Metal Arm Futon Review

There were a lot of things that we loved about this futon. The following features stood out to us during our review:

Bold Red Color

Although this futon’s design is simple, its ruby red mattress color makes this piece stand out. It will easily be the focal point of the room. If you’re not a fan of red, you may be able to find a Mainstays metal arm futon with mattress black on Amazon or another online retailer.

Smart, Comfortable Design

This red sofa bed features an economical design with a low-sitting frame. The frame sits 10” off the floor, which makes it easy to get on and off the futon whether you’re using it as a bed or a sofa for guests to sit on.

Because of its low design, this is the best sofa sleeper for anyone living in a studio apartment or dorm.

We were also surprised to find that mattress itself was very comfortable. Typically, futons are hard, uncomfortable and cause back pain. But this model is different. That’s because the mattress is made from a thermos-bonded polyester and cotton core. There are no springs in the mattress, which often cause pain or dig into your back at night.

This is the best sleeper sofa mattress in terms of comfort that we have ever seen on a futon.

That said, we did notice one slight issue with this mattress: It falls flat after extensive use (2+ years). In truth, at this price point, this wasn’t surprising. But the mattress will only fall flat after extensive, heavy use. If you’re simply using this for guests, you shouldn’t have any issues with the mattress for years. And if you use this as your daily bed, you always have the option of ordering a replacement.

Environmentally-Conscious Design

If you’re concerned about the environment, you’ll be happy to know that this futon’s mattress is made from Earth-friendly materials and contains a minimum of 50% pre-consumer recycled content.

Not only does this futon have a contemporary design, but the company takes a modern, eco-friendly approach to the production of this product.


When folded up, this futon can serve as a coach or sofa. It’s comfortable, durable and you can sit on it for long periods of time without any issues.

In just a few simple steps, you can convert the sofa into a full-size bed. After laying on this futon, we can confidently say that you can easily fit two people on this bed.

The versatility of this futon is what makes it such a great choice for small studio apartments and living rooms. Use it as your permanent bed to save on space, or for unexpected guests. If a friend or family member drops in, you can now offer them a comfortable place to sleep for the night.


One of the major advantages that this futon offers is that it’s so lightweight. Most sleeper sofas weigh hundreds of pounds, but this model weighs just 50 pounds. This means that you can easily move the mattress and the frame from one room to another if you need to.

The Final Verdict

We’ve tried a lot of sofa beds (and we have a long list of sleeper sofa reviews to prove it), and this Mainstays model is one of the better options in this price range. It’s comfortable, the design is modern, and the red mattress color will add flair to your space. Assembly is difficult, but not a deal-breaker. You may have issues with the mattress in the future, but that’s to be expected with any futon.

Overall, we felt that this sleeper sofa was a great buy. It’s ideal for anyone living in a studio apartment or dorm room. It’s also an affordable option for guest rooms and second living rooms for unexpected guests. If you’re looking for a futon that won’t break the bank but is still comfortable to sit or sleep on, the Mainstays Metal Arm Futon is a smart option.
