DEHIJU Full Size Mattress: Complete Buying Guide for Smarter Sleep

A good mattress can change your nights—and your mornings. If your current bed leaves you sore, sweaty, or wide awake at 3 a.m., it may be time for an upgrade. The DEHIJU Full Size Mattress has gained attention online for offering hybrid comfort at a price that feels surprisingly reasonable.

With multiple thickness options and thousands of customer reviews across major retailers, it’s become a popular pick for budget-focused shoppers looking for pressure relief and coil support in one bed.

Hybrid mattresses now account for a growing share of online mattress sales, according to industry data from the International Sleep Products Association, as more shoppers look for balanced comfort instead of all-foam designs. So how does this one perform in real life? Here’s what you need to know before adding it to your cart. Let’s

If you’re searching for a full size hybrid mattress, this model combines foam comfort with coil support in a simple, practical design. Here are the core specs:

• Sizes: Full (54" x 75")
• Thickness options: 10", 12", and 14"
• Feel: Medium-firm
• Construction: Gel memory foam + individually wrapped pocket springs
• Certification: CertiPUR-US® certified foam
• Delivery: Compressed mattress in a box
• Price on Amazon (at time of review):
• 10" – $218.99
• 12" – $258.99
• 14" – $309.99

The mattress arrives tightly rolled in a box. Setup takes about 10–15 minutes, then you’ll want to allow up to 48 hours for full expansion. If you’ve handled bed-in-a-box models before, the process feels familiar and manageable—even in apartments or tight stairwells.

Understanding what’s inside helps you decide if this full size memory foam mattress meets your needs.

1. Gel-Infused Memory Foam Top Layer

The top layer uses gel-infused foam designed to contour around shoulders and hips. The gel aims to reduce heat buildup, a common issue with traditional foam beds. Side sleepers typically notice the pressure relief most in the shoulder area. Back sleepers often report better lumbar cushioning compared to older innerspring beds.

2. Individually Wrapped Pocket Coils

Each coil moves independently. This improves targeted support and reduces motion transfer. If your partner shifts at night, you’re less likely to feel it compared to traditional connected springs. Couples searching for the best full size mattress for couples often prioritize this feature.

3. High-Density Support Base

Under the coils sits a stabilizing foam layer. It reinforces the structure and supports long-term durability.

4. Breathable Knit Cover

The outer cover is soft and promotes airflow. It’s not a luxury cooling fabric, but it does feel breathable to the touch.

After reviewing customer feedback and testing similar hybrid builds over the years as a sleep product analyst, here’s how this mattress generally performs.

Pressure Relief

The foam layer distributes weight evenly. For sleepers under 230 pounds, the medium-firm profile tends to feel balanced. Heavier sleepers may notice deeper sinkage over time.

Motion Isolation

Thanks to the pocket coils, movement stays fairly contained. For couples, this can mean fewer nighttime disturbances.

Temperature Regulation

The gel infusion helps moderately with heat. It won’t feel like an advanced cooling mattress, yet it performs better than basic all-foam models.

Edge Support

Edge support is decent for the price. Sitting directly on the edge causes some compression. If you rely heavily on perimeter support, higher-end hybrids usually perform better.

Across major online retailers, this mattress averages around 4.4 out of 5 stars. Common praise includes:

• Strong value for the cost
• Comfortable medium-firm feel
• Easy setup
• Minimal motion transfer

Common concerns include:

• Mild off-gassing during the first 24–48 hours
• Softer feel than expected for some users
• Durability questions after extended heavy use

From a consumer perspective, many buyers upgrading from older spring mattresses describe noticeable improvements in comfort. However, shoppers moving from premium luxury brands sometimes describe it as supportive but basic. That contrast makes sense given the price tier.

If you’re looking for an affordable full size mattress, this one fits certain situations very well.

Great Fit For:

• Budget-conscious shoppers
• Guest rooms
• College students
• First apartments
• Couples wanting motion isolation
• Combination sleepers

The price point makes it appealing for temporary setups or primary bedrooms on a modest budget.

No mattress fits everyone. Here are realistic limitations.

Heavier Individuals (Over 230 lbs)

Higher body weight increases compression on foam layers. You may benefit from a mattress built specifically for higher weight capacity.

Very Firm Mattress Fans

If you prefer a very firm surface with minimal sink, this medium-firm feel may seem softer than expected.

Luxury Seekers

Premium features like zoned lumbar reinforcement, hand-tufting, or natural latex are not included here. Understanding trade-offs helps you avoid disappointment.

The foam is CertiPUR-US® certified. This means it’s tested for:

• Low VOC emissions
• No formaldehyde
• No heavy metals
• No ozone depleters

According to the Environmental Protection Agency (EPA), indoor air quality plays a significant role in overall health. Lower VOC emissions help reduce potential indoor air pollutants, which is important in bedrooms where you spend many hours nightly. You may notice a mild odor when unboxing. It usually fades within two days.

To extend the lifespan of your DEHIJU Full Size Mattress, follow these simple practices:

• Rotate 180° every 3–6 months
• Use a mattress protector
• Place on a supportive foundation
• Avoid prolonged sitting on edges

Industry data from sleep research groups suggests hybrid mattresses typically last 6–8 years on average, depending on usage and body weight. Given its budget tier, expecting performance within that range is realistic.

From a budget standpoint, the value is clear. At around $218.99 to $309.99, you’re getting hybrid construction at a cost often associated with basic foam beds. From a durability standpoint, premium brands may offer longer warranties and thicker coil systems.

From a comfort standpoint, most average-weight sleepers report satisfaction. So the final decision depends on your priorities: upfront savings or long-term investment.

If you want balanced comfort without stretching your budget, this mattress delivers practical value. You get foam contouring, pocket coil support, and easy delivery at a price that fits smaller budgets. It works especially well for couples, guest rooms, and first-time buyers.

It may not compete with high-end luxury models, yet it covers the essentials most sleepers need.
