Best Six Inch Mattress – Details

1. Top Recommendation – PlushBeds RV Memory Foam Mattress

PlushBeds Six Inch Mattress - Memory Foam

Why’s this the top pick? This mattress is amazing quality for your money. Under the soft knit cover, you’ve got 6 inches of very high quality memory foam which has been engineered to both keep you cool (through its open cell structure) and relieve your pressure points. In fact, the memory foam PlushBeds use is three times as dense as “regular” foams, hence its ability to support you while you sleep and have a 20 year warranty (twice as long as most other memory foam mattresses.

Oh, and there’s no fiberglass fire barrier here, like you find in many other mattresses at this price point: PlushBeds use an eco fire barrier made from natural plant fibers.

  • Price: From $540 (on sale)
  • Sleep Trial: 100 Nights
  • Warranty: 20 Years (this is absolutely massive for a memory foam mattress)
  • Composition: Deluxe stretch knit cover, plant based fire barrier, “Plush Foam” memory foam core
  • Firmness: Universally comfortable medium
  • Sizes: Twin, RV Special, Full, Queen, Queen Short, King
  • Certifications: GreenGuard Gold certified (a chemical emissions standard)
  • Made In: USA

2. PlushBeds Natural Bliss 6 Inch Latex Mattress

PlushBeds Natural Bliss 6 Inch Mattress

Why show another one from PlushBeds? I wanted to show you an option that wasn’t memory foam, and latex is your best bet because it’s naturally durable, cooling, and extremely comfortable. PlushBeds make the best latex mattresses on the market and they’re the only brand I could find offering a great six inch mattress option so I couldn’t not include this one. Again, there’s no fiberglass in any PlushBeds mattresses.

  • Price: From $1149 (on sale)
  • Sleep Trial: 100 Nights
  • Warranty: 25 Years (longer than you’ll get for most mattresses, no matter their thickness)
  • Composition: Organic cotton stretch cover, plant based fire barrier, organic latex core
  • Firmness: Your choice of medium-firm or firm
  • Sizes: Twin, Twin XL, Full, Queen, Split Queen, King, Split King, California King, Split California King
  • Certifications: GreenGuard Gold certified
  • Made In: USA

3. Best Budget Choice: Zinus Green Tea

Zinus Green Tea 6 Inch Mattress

Why’s this one on the list? Even though this is the flimsiest of the three and it has a fiberglass fire barrier, it’s worth bringing to your attention because it’s still a good mattress for the price. You’ll need to check the exact Amazon price, but I can guarantee you it’s going to be less than half the other best six inch mattress options. Zinus uses some really clever foams here, with the green tea and charcoal infusions acting as temperature regulators, fresheners, and antibacterial agents. This mattress is a consistent Amazon top seller with thousands and thousands of very happy customers.

Why do I say it’s flimsy? Because it’s got very thin comfort layers and then a base layer, so you’re going to potentially sink through the comfort layers pretty quickly, which isn’t going to happen with the other mattresses. I also believe the foams inside this mattress are lower quality so the mattress isn’t going to be as durable, but that’s the tradeoff for the extremely budget friendly price.

  • Price: Check on Amazon
  • Sleep Trial: None, this one is subject to Amazon’s usual returns policy
  • Warranty: 10 Years
  • Composition: Stretch polyester cover, fiberglass fire barrier, 1″ green tea and charcoal infused memory foam, 1″ transition foam, 4″ base foam
  • Firmness: Medium-firm (the comfort layers are very thin, so it’s going to err on the side of firm as you sink through the comfort layers quicker)
  • Sizes: Narrow Twin, Twin, Full, Queen, Short Queen, King
  • Certifications: CertiPUR US Certified
  • Made In: China

Best Six Inch Mattress – Buyer’s Guide

Six inches is one of the slimmest mattresses you can get, so you need to think carefully about where you’re going to use them. A mattress that’s only six inches thick has a limited capacity for support and comfort layers, so they tend to feel firmer than a thicker mattress that uses the same materials. For example the Zinus Green Tea 10 inch mattress is more of a true medium while the 6 inch model is firmer.

The slim profile of a six inch mattress makes them the perfect choice for some situations, but I’d never recommend an adult buys one for their everyday bed. Here’s when a six inch mattress is going to be a good choice:

  • Trundler beds
  • Child’s bed
  • Bunk beds
  • Guest room
  • RV mattress

Is A Six Inch Mattress Good?

Yes, they absolutely can be when used in the right context. They’re perfect for when you need a thinner mattress: think RVs or bunk beds. They can also be a good budget choice for a child’s first mattress.

Is A Six Inch Mattress Too Thin?

If you’re looking for an every day mattress for an adult, yes I think it’s too thin. It’s not too thin for kids, bunks, or or occasional use.

Can You Sleep On A Six Inch Mattress?

Yes you can. But if you’re looking for a new every day mattress for an adult, I recommend you choose something thicker – at least 10 inches to guarantee the best balance of support and comfort layers.
