The Best Extra-Long Twin Bed

Basic platform bed frames are strong enough to support mattresses without needing an additional box spring mattress. They usually sit lower to the ground than bed frames with box springs, with open space beneath them.

You can find good ones priced at under $300, and the heavy-duty ones can support as much as 3,000 pounds. Ones made from metal are generally stronger than wood, but read the product descriptions if you need to know the weight limit.

One of the best aspects of these frames is that they are up off the ground, but some are not as high, so you’ll want to check those measurements. If you have an extra 15 inches or so of space underneath, that’s a lot of room for shoes, clothes and other things.

As for the length and width of the mattress, look at those as well before making a purchase. A standard twin XL mattress measures 80 inches by 38 inches. This size frame usually costs a bit more than a standard twin, and those mattresses are five inches shorter, at 75 inches by 38 inches.

Modern platform bed frames are solid, reliable and built with slats for added support. Mattresses should fit well without any overhang or extra room and should remain stable and not slip when on top. Some require more assembly than others, so if you’re not handy, get some help or look for easier ones to put together. You can also buy a foldable mattress frame, which is excellent to have if you have extra company or need to transport it somewhere.

• Freestanding bed frames are simple designs without any embellishments; you can find ones with integrated headboards and footboards.
• If the frame’s legs don’t have protective coverings on the bottoms, they could damage your floors. You can buy these separately.
• Flimsy metal will be less durable and can make a lot of noise, so do your research before buying. No one wants to be kept up at night by a squeaky bed frame.
• Look at the number of slats and their spacing. More, closer slats mean added strength.
• Larger bed frames can have central legs for added support.
• XL twin sheets can be harder to find in stores; look for them online and before school starts because college dorms usually provide these size beds.
