Quick Take
The Purple Kids Mattress is genuinely different from any other mattress I have evaluated. The signature Purple Grid is not marketing hype - it is actual engineering innovation that provides unique pressure relief and temperature regulation. Whether that unique feel works for your child is another question. Some kids love it; others find it strange. The certifications are adequate (CertiPUR-US, no fiberglass) but not as comprehensive as organic options.
Why I Researched This
Purple has built a cult following around their grid technology, and parents kept asking me about the kids version. I was skeptical - is the grid just a gimmick, or does it actually work? After researching the material science and testing the mattress, I am convinced the technology is legitimate, even if it is not the safest option in the category.
What We Evaluated
This review uses R3's kids-mattress methodology v1.0.0, evaluating 30 factors across 6 pillars: Safety (35%), Efficacy (30%), Value (15%), Usability (10%), Sustainability (5%), and Suitability (5%).
Understanding the Purple Grid
Before diving into scores, let me explain what makes Purple different.
Hyper-Elastic Polymer Grid The Purple Grid is a grid structure made from a proprietary hyper-elastic polymer. Think of a large grid of flexible columns that compress under pressure and spring back instantly. The material is food-contact safe (same polymers used in medical devices and baby bottle nipples).
How It Works When weight is applied, the grid columns buckle and collapse. Heavier body parts (hips, shoulders) compress the grid more, creating natural contouring. Lighter areas maintain support. This creates a balance of pressure relief and support without the sinking feeling of memory foam.
Temperature Regulation The grid structure has hundreds of air channels. Body heat dissipates through these channels rather than being trapped against the body. This is not marketing - the physics actually work. Purple mattresses consistently test cooler than foam.
Instant Response Unlike memory foam that slowly conforms and slowly releases, the hyper-elastic polymer responds instantly. Press down and release - the grid bounces back immediately. This means no 'stuck' feeling and easy position changes.
Safety Analysis (35% weight)
CertiPUR-US Certified: Yes (8/10) The foam layers in the Purple Kids are CertiPUR-US certified. This covers formaldehyde, heavy metals, PBDEs, and VOC emissions. Standard certification for foam mattresses.
No GREENGUARD Gold: No Unlike some competitors, the Purple Kids does not carry GREENGUARD Gold certification. This is a gap in the safety profile compared to mattresses like Tuft & Needle.
No Fiberglass Fire Barrier: Yes (9/10) Purple does NOT use fiberglass in their fire barriers. They use a flame-retardant barrier sock that does not contain fiberglass fibers. This is important - many budget mattresses use fiberglass which can escape and spread.
Hyper-Elastic Polymer Safety: 8/10 The Purple Grid material is food-contact safe, meaning it meets FDA standards for materials that touch food. It is non-toxic and free of harmful substances. However, it is not certified organic - it is an engineered material.
Off-gassing: 7.5/10 Expect some off-gassing from the foam layers during the first few days. The grid itself has minimal odor. Overall off-gassing is similar to other foam mattresses - noticeable initially but dissipates within 48-72 hours.
Material Transparency: 7/10 Purple is less transparent about exact material compositions than organic brands. They provide general information about the grid and foam certifications but not detailed specifications.
What Purple Kids is NOT
Not Organic The foam layers are synthetic, not organic latex. The cover is not GOTS certified. No wool fire barrier.
Not GREENGUARD Gold Certified This is a meaningful gap. GREENGUARD Gold tests the finished product for over 10,000 chemicals. CertiPUR-US only tests the foam components.
Not for Infants The Purple feel is designed for kids who can appreciate the pressure relief - generally ages 4+. Infants need firmer, simpler surfaces.
Performance & Efficacy (30% weight)
This is where Purple shines. The grid technology genuinely delivers on performance claims.
Pressure Relief: 10/10 Exceptional pressure relief from the grid structure. The columns buckle under pressure points (hips, shoulders) while maintaining support elsewhere. Kids with growing pains or who complain of hip/shoulder discomfort often find relief on Purple.
Spinal Support: 9/10 The grid provides responsive support that adapts to body position. Maintains spinal alignment for side, back, and stomach sleepers. The support layer beneath the grid provides stability.
Temperature Regulation: 10/10 Outstanding cooling from the air-channel design. The grid is temperature-neutral - it does not retain body heat. Kids who sleep hot consistently report cooler nights on Purple. This is a legitimate differentiator.
Responsiveness: 10/10 Instant response to movement. The hyper-elastic polymer bounces back immediately - no sinking or trapped feeling. Great for restless sleepers who change positions frequently.
Durability: 8.5/10 The grid is extremely durable - it does not compress or degrade like foam. The support foam layers may show wear over time. Expected lifespan of 8-10 years with proper care.
Unique Feel: Variable Here is the catch: the Purple feel is genuinely unusual. Some kids love it immediately. Others find the grid sensation strange and prefer traditional foam or coil. I recommend taking advantage of the trial period to determine if your child likes the feel.
Value Assessment (15% weight)
Price: 6.5/10 $849 for the twin size puts it in premium territory without the organic certifications of similarly-priced options. You are paying for the proprietary technology, not organic materials.
Warranty: 9/10 10-year warranty covering defects and sagging. Purple has reasonable warranty honor rates.
Sleep Trial: 9/10 100-night trial with free return pickup. Essential given the unique feel - you need time to determine if your child actually likes the grid sensation.
Innovation Premium You are paying a premium for patented technology. Whether that innovation is worth the price depends on whether your child benefits from the unique pressure relief and cooling.
Usability Factors (10% weight)
Setup: 9/10 Ships compressed in a box. The grid rebounds to full shape quickly - faster than memory foam expansion. Ready to sleep on within 24 hours.
Weight: 7/10 Heavier than all-foam options due to the grid material density. Twin is approximately 55-60 lbs. Two people helpful for setup.
Cover: 8/10 Soft SoftFlex cover is moisture-wicking and breathable. Removable and machine washable. Not organic, but comfortable and practical.
Cleaning Grid: 8/10 The grid can technically be cleaned - it is water-safe and durable. Most families just use a waterproof protector and clean the cover.
Company & Sustainability (5% weight)
B Corp: Not Certified Purple is not B Corp certified. They are a publicly-traded company (NYSE: PRPL) focused on growth and profitability.
Sustainability: Moderate Purple has some sustainability initiatives but is not a leader in this area. The grid material is durable (less replacement waste) but the overall sustainability profile is average.
American Manufacturing: Yes Mattresses are manufactured in the USA (Utah). Domestic production with job creation.
The Unique Feel Question
I want to be direct about this: the Purple Grid feels different from any other mattress. The sensation of the grid columns beneath you is unusual. Some descriptions:
- 'Floating on a firm cloud'
- 'Like sleeping on a really supportive egg crate'
- 'Bouncy but supportive'
- 'Weird at first, then amazing'
- 'Too strange - went back to foam'
There is no way to know if your child will like it without trying. Use the 100-night trial. Give it at least 2-3 weeks of adjustment before deciding.
Who Should Consider Purple Kids
- Kids who sleep hot and struggle with temperature regulation
- Children with growing pains or pressure point discomfort
- Restless sleepers who change positions frequently
- Kids ages 4+ who can articulate whether they like the feel
- Families not prioritizing organic materials
Who Should Look Elsewhere
- Families seeking organic certifications
- Infants and toddlers (need firmer, simpler surfaces)
- Those who want GREENGUARD Gold certification
- Kids who prefer traditional foam or coil feel
- Budget-conscious families (better value elsewhere at this price)
The Bottom Line
The Purple Kids Mattress is the most innovative mattress in the category - the grid technology genuinely delivers exceptional pressure relief and cooling. The certifications (CertiPUR-US, no fiberglass) are adequate but not comprehensive. The unique feel is either wonderful or weird depending on your child. At $849 without organic certifications, the value proposition depends entirely on whether your child loves the grid feel.
