Benefits of The Purple GelFlex™ Grid

Cushions + Supports
The Grid’s columns give way under focused pressure from hips and shoulders to gently cradle your body, while offering support to broad, evenly distributed weight (lookin’ at you, legs and back).

Dissipates Body Heat
The Grid features 1,400+ ventilation chambers for better airflow. Plus, when it comes to temperature, our GelFlex material is like Switzerland – totally neutral – so you won’t sleep too hot or too cold.

Adapts as You Move
The GelFlex Grid instantly shifts as you change your sleeping position. When you move, it moves, so you feel every inch of comfortable support and your sleep remains blissfully uninterrupted.
Is a Full Size Right For Me?
- The full size mattress is the same length as a twin but is 16 inches wider.
- The full is an ideal option for single sleepers wanting more space to move around in bed.
- As a general rule of thumb, your bedroom space should be at least 9x9.5 feet to provide plenty of space.

Frequently Asked Questions
The cost of a full size mattress can vary significantly across brands. Purple offers three full size mattresses ranging from $1199-$3499. Financing options are also available for as low as 0% APR. All Purple mattresses include free shipping and free returns, a 100-night risk-free sleep trial, and a 10-year limited warranty.
No matter which Purple you choose, you can enjoy the instant response and No Pressure Support of our patented Purple GelFlex™ Grid. The Purple® Hybrid and Hybrid Premier also include individually wrapped pocket coils for an added level of responsiveness and support.
A full size mattress used to be the standard mattress for couples, but these days it’s considered to be a bit small. A full size mattress is only 54 inches wide, which leaves each sleeper just over 2 feet of wiggle room. That’s not very much, especially for larger folks. For that reason, the queen mattress has become the new standard for couples. If you’re both average to petite in size (or especially fond of cuddling), then a full bed may be fine.
Purple mattresses are especially good for couples. The Purple GelFlex™ Grid found in all Purple mattresses has adaptive firmness, so it can provide no-pressure support regardless of body type or sleep position. Even if you and your partner prefer drastically different mattress types, you can both get a great night’s sleep on a Purple.
The best place to buy a Purple full mattress is right here at purple.com. Enjoy free shipping and free returns, a 100-night sleep trial, and a 10-year warranty. To top it off, we love to toss in freebies and additional discounts with your purchase.

No, you don’t need a box spring with your full mattress. In fact, we don’t recommend it. Purple Mattresses are best supported by a bed frame or foundation and not a box spring. We offer a line of sturdy and attractive bed frames that are made to suit Purple mattresses perfectly.

Note: Be sure to check your mattress warranty. Some warranties require the use of a specific type of mattress base or bed frame. If you don’t adhere to the guidelines, you risk voiding your warranty.
No, a full size mattress is not the same as a queen mattress. Let’s take a look at queen and full size mattress dimensions to compare:
Full mattress: 54 x 75 inches
Queen mattress: 60 x 80 inches
The queen bed size is 5 inches longer and 6 inches wider than a full bed. For this reason, the queen bed is a popular mattress for couples and a full size bed is generally recommended for a single adult or teen sleeper.
There are a few reasons. First, American bedrooms and homes have become larger over time. With bigger spaces to fill, people have opted for larger beds that give them more space to sleep. The queen's extra space makes it easier to change positions, and the extra distance between sleepers can help the bed stay cooler.
These days, we use our beds for more than sleeping. A study found that while Americans only sleep about 7 hours per night, they spend an additional 4 hours each day in bed doing other things like watching shows and scrolling on their phones. Now that the bed has become a space for activities, it’s only natural that people want to upgrade to a larger size.
But the queen’s reign may soon be over. The king mattress and California king mattress are also popular choices for the master bedroom. King size mattresses offer even more sleeping space, which is especially helpful for accommodating children and pets.
If you’re looking for an all-around great mattress for any sleep position and body type, Purple is the way to go.
