This comparison names the exact products because both brands sell several mattresses with different constructions. It uses manufacturer specifications checked September 30, 2026. We have not slept on these models, measured cooling or pressure, or assigned performance scores. The brands' descriptions explain their designs but are not independent tests.

Adaptive foam versus GelFlex Grid
T&N says its Original Mattress II combines Adaptive foam with support and base foam. The published feel is firm. This may appeal if you prefer a conventional foam surface with a quicker response than traditional memory foam. The product page describes graphite and gel in the comfort foam; we have no comparative temperature measurements for this mattress.
Purple says The Purple Mattress places a 2-inch GelFlex Grid above comfort and support foam. The grid bends under concentrated weight, making it a different surface from a continuous foam layer. Purple describes this model as medium-firm. Whether that feel improves comfort for your body or sleeps cooler in your room is a personal and environmental question that the specifications alone cannot answer.
Which should you shortlist?
- Start with T&N Original Mattress II if you are looking for a firm, all-foam design and want to compare its current price and return terms with other foam beds.
- Start with The Purple Mattress if you want to try the GelFlex Grid's distinct surface feel and a medium-firm model.
- Try both in person if possible. Brand firmness labels and material descriptions cannot predict personal comfort, motion sensitivity, or temperature perception.
Before buying, check the selected size, foundation requirements, full return conditions, and current total price. Purple's product page specifies compatible bases; Tuft & Needle lists frame compatibility on its page.
Quick questions
Are both mattresses all foam? The T&N Original Mattress II uses foam layers. The Purple Mattress uses a GelFlex Grid over foam layers and does not use coils. Other models from both brands have different constructions.
Is the Purple Mattress softer? Tuft & Needle calls the Original Mattress II firm; Purple calls The Purple Mattress medium-firm. These are the brands' labels, not a standardized measurement, and the grid may feel unfamiliar even if you know your usual firmness preference.
Which mattress sleeps cooler? We have no independent measurements for this exact pair. Both brands describe cooling features. Room temperature, bedding, and the sleeper can change the result, so treat cooling claims as features to assess during a trial.
