How Much Is a Full Size Mattress? Typical Costs and What Affects the Price

If you’re asking “How Much Is a Full Size Mattress”, you’re usually trying to figure out a realistic budget, what affects the price, and whether a full size is good value for your space. This FAQ-style guide explains common price ranges, what drives costs up or down, and how to choose a full mattress that fits both your room and your wallet.

What Is a Full Size Mattress?

A full size mattress (also called a double) is a standard mattress size that’s wider than a twin but smaller than a queen. Many sleepers choose it for:

• Single adults who want more room than a twin
• Teens and older kids
• Guest rooms
• Smaller bedrooms or studio apartments

It’s often seen as a budget-friendly upgrade from a twin without the higher price of larger sizes.

So, How Much Is a Full Size Mattress on Average?

When people search “How Much Is a Full Size Mattress”, they’re usually looking for a general price range. While prices vary by brand, materials, and construction, most full size mattresses fall into a few broad tiers:

These are rough ranges, not fixed rules. Some mattresses may fall slightly outside them, but they give a useful starting point for budgeting.

What Factors Affect the Cost of a Full Size Mattress?

1. Mattress Type

Different constructions have different typical price levels:

• Innerspring: Often among the more affordable, especially in budget ranges.
• Foam (including memory foam): Ranges from low-cost to mid-range depending on foam quality and thickness.
• Hybrid (foam + coils): Commonly priced mid to higher range due to more complex construction and materials.
• Latex: Frequently on the higher end, especially when made with higher-cost materials.

2. Materials and Density

Higher-density foams, thicker comfort layers, and more complex coil systems usually cost more to produce, and that’s reflected in the price. Many shoppers are willing to pay more for:

• Thicker comfort layers
• More supportive coil systems
• Specialized foams or cooling materials

3. Height and Construction Complexity

A taller mattress with multiple layers often sits in a higher price bracket than a thinner, simpler model. Extra edge support, zoned support regions, or specialized transition layers can also increase cost.

4. Where You Buy It

Online-only brands may sometimes offer lower prices than traditional retail stores because of different overhead costs. In-store models may be priced higher but provide an opportunity to try before you decide.

Is a Full Size Mattress Worth It Compared to Other Sizes?

Many shoppers compare prices across sizes while asking, “How Much Is a Full Size Mattress”.

In general:

• A full costs more than a twin, but usually not dramatically more.
• A full is usually cheaper than a queen in the same model line.

For people who don’t need the extra width of a queen, a full mattress can offer a balance of comfort, space-saving, and cost control.

How Much Should I Budget for a Good Full Size Mattress?

“Good” can mean different things depending on comfort preferences and priorities, but many consumers find a reasonable balance of quality and price in the mid-range:

• Around $400–$900 often covers mattresses with:
  • Multiple foam or comfort layers
  • More robust support systems
  • A more substantial, durable feel

Budget models under $400 can still be suitable for:

• Occasional guest use
• Short-term living situations
• Lightweight sleepers with simple needs

Higher-end models above $900 may appeal to sleepers who want more specialized construction or more luxurious materials.

What Extra Costs Should I Consider?

The question “How Much Is a Full Size Mattress” often overlooks related expenses. A few common add-ons:

• Foundation or bed frame: If you don’t have a compatible base, this can add to the total.
• Bedding: Full size sheets, protectors, and blankets are widely available and usually less expensive than queen or king sets.
• Delivery or setup: Some retailers include this, while others may charge a fee.

Factoring in these extras can give you a more realistic total budget.

Who Is a Full Size Mattress Best For?

A full size mattress is often a good fit if you:

• Sleep alone and want more room than a twin offers
• Have a smaller bedroom where a queen or king would feel cramped
• Want to keep costs lower while still upgrading to a larger size than a twin

Two adults can technically share a full, but many couples eventually prefer the extra width of a queen or king for personal space.
