The best innerspring mattress available online. Three firmness levels (Plush Soft, Luxury Firm, Firm) and two height options (11.5" and 14.5") make it one of the most customisable mattresses at any price. Dual coil construction delivers the bouncy, supportive feel of a traditional hotel mattress with better pressure relief. White glove delivery and old mattress removal included. The 365-night trial and lifetime warranty are among the best guarantees in the industry.
Purple's proprietary GelFlex Grid technology is unlike any other mattress material. The grid simultaneously supports your body and collapses under pressure points without the sinking, trapping feeling of memory foam. The result is pressure relief without heat retention. Best for side sleepers and those who run hot.
TEMPUR material is the original viscoelastic foam — it conforms more precisely and recovers more slowly than any competing memory foam. The Adapt Medium Hybrid adds a pocketed coil support core beneath the TEMPUR comfort layers, improving airflow, edge support, and responsiveness. The combination produces the pressure-relieving contouring TEMPUR is known for with more bounce.
The Wave Hybrid uses zoned support — firmer under the hips and lumbar to prevent sinking, and softer under the shoulders for pressure relief. For side sleepers, this zoning means the spine stays aligned without a shoulder pressure point. The hybrid construction provides good bounce and edge support.
The Nectar Premier Copper delivers premium memory foam sleep at a significantly lower price than Tempur-Pedic. The copper-infused cover and gel memory foam address heat retention. The 365-night trial matches Saatva as the longest in this comparison. At $1,499 for a Queen, it provides around 80% of the TEMPUR experience at 60% of the price.
The DreamCloud Premier Rest is the best entry point into hybrid mattress ownership. Cashmere blend cover, gel memory foam, and an 8" pocketed coil support core at $1,199 for a Queen. The 365-night trial is one of the longest available. A good first adult mattress or guest room upgrade.

Side sleepers need softer pressure relief at the shoulder — the Purple Restoring Premier and the Casper Wave Hybrid both target this. Back sleepers need firmer lumbar support — the Saatva Classic (Luxury Firm) and Tempur-Pedic Adapt Medium Hybrid excel here. Stomach sleepers need firm, flat support — the Saatva Classic (Firm) is the best choice.
Memory foam retains heat. The Nectar Premier Copper addresses this with copper-infused foam and gel layers. The Purple Restoring Premier is the best performer: the GelFlex Grid has open air channels that allow heat to escape. The Saatva Classic also sleeps cool due to airflow through the coil layers.
Motion isolation is the key factor for couples. The Tempur-Pedic Adapt Medium Hybrid and Nectar Premier Copper score very high here. The Saatva Classic transfers some motion through its coils, though the pocketed micro-coil top layer mitigates it. If one partner is a light sleeper, prioritise motion isolation over bounce.
Spinal alignment is the priority. The Tempur-Pedic TEMPUR-Adapt Medium Hybrid provides the most precise body contouring — TEMPUR material was originally developed for NASA pressure relief. The Saatva Classic (Luxury Firm) provides excellent lumbar support from its dual-coil system. Both are recommended by sleep specialists for back pain management.
The DreamCloud Premier Rest at $1,199 is the best entry point — hybrid construction, 365-night trial, lifetime warranty. The Nectar Premier Copper at $1,499 adds copper-infused heat management. Above $2,000, Tempur-Pedic and Purple use proprietary materials unavailable elsewhere. The Saatva Classic at $1,295 offers the most customisation at its price.
What is the difference between innerspring, memory foam, and hybrid mattresses?
Innerspring mattresses use steel coil systems — they sleep cool, have good bounce and edge support, but less pressure relief. Memory foam conforms closely and excels at pressure relief and motion isolation, but retains heat. Hybrid mattresses combine pocketed coils with foam comfort layers. The Purple GelFlex Grid is a fourth category: a polymer grid that simultaneously supports and relieves pressure with excellent airflow.
How long should a mattress last?
A quality mattress should last 7-10 years for foam and hybrid constructions, and 10+ years for quality innersprings. The Saatva Classic comes with a lifetime warranty. Tempur-Pedic materials are known for exceptional durability. Budget foam mattresses typically begin to sag noticeably at the 5-6 year mark.
What does a sleep trial actually mean?
A sleep trial allows you to return the mattress for a full refund within the stated period. Most brands offer 100 nights minimum. Saatva, Nectar, and DreamCloud all offer 365 nights. The trial is genuinely valuable: a mattress that feels comfortable in a showroom may not work for your specific sleep position and temperature preferences over time.
Is a firmer mattress better for back pain?
Not necessarily. Research suggests medium-firm is optimal for most people with back pain. A mattress that is too firm creates pressure points at the hips for side sleepers. The Saatva Classic Luxury Firm and the Tempur-Pedic TEMPUR-Adapt Medium Hybrid are both engineered around medium-firm principles.
What size mattress should I buy?
Queen (60 x 80 inches) is the most versatile — suitable for couples and single sleepers. King (76 x 80 inches) adds 16 inches of width, significant for couples where one partner moves a lot. California King (72 x 84 inches) suits taller sleepers over 6 foot 2. All mattresses in this comparison are available in Queen and King.
