Soft cushioning should ease pressure without leaving you feeling unsupported
A firm mattress can press into your hips and shoulders, while an overly plush surface may let your lower back dip. The best softest foam mattress topper should add cushioning that suits your sleep position without pretending to repair a mattress with deep sagging. These picks include memory foam, fiber-and-foam fills, and pillow-top styles, so softness and support vary from one design to another.
After carefully analyzing the listed product specifications, the standout differences are thickness, foam construction, airflow features, and how each topper stays on the bed. The 3-inch OLIXIS uses gel-infused, ventilated memory foam, while SHOUREN combines gel memory foam with shredded foam in a 5-inch profile. Those details can help you narrow the options, but comfort remains personal, and cooling features are not a promise that every hot sleeper will stay cool. For more help with pressure-relieving topper features or ways to address a shifting topper, use the linked guides as extra reference.

SHOUREN 5-Inch Queen Memory Foam Mattress Topper
The SHOUREN 5-Inch Queen Mattress Topper combines cooling gel memory foam with supportive shredded foam to deliver plush contouring and pressure relief over an aging or overly firm mattress. Rated around a plush medium-soft feel, it is an accessible upgrade for side and back sleepers seeking pressure relief around the hips and shoulders.
Pros

- Dual-layer structure blends contouring gel foam with shredded foam to avoid bottoming out on firm beds.

- Breathable dot-quilted cover prevents the shredded filling from shifting or clumping over time.
Cons
- Adds significant height (5 inches), which may require extra-deep pocket fitted sheets.
- Requires 24 to 48 hours in a ventilated space to decompress fully and dissipate initial boxed foam odors.
- The plush sink-in profile may feel too soft for dedicated stomach sleepers needing rigid pelvic elevation.

FAQs
Is a 3-inch or 5-inch topper better for pressure relief?
A 3-inch topper adds a substantial cushion, while a 5-inch profile creates a much thicker change to the bed feel. OLIXIS offers a 3-inch gel memory foam option; SHOUREN pairs gel memory foam and shredded foam in a 5-inch design. Check your sheet depth and preferred support before buying a thicker overlay.
Which of these toppers may suit a hot sleeper?
The OLIXIS 3 Inch Queen Memory Foam Mattress Topper is described as gel-infused and ventilated, with open-cell channels intended to encourage airflow. WhatsBedding highlights airflow channels and a cool-to-the-touch surface. These are product claims, not a guarantee of a specific temperature change, so bedding and room conditions still matter.
Can a soft memory foam topper fix a sagging mattress?
No, a topper cannot repair a collapsed or broken mattress. OLIXIS explicitly states that its topper is for use over a mattress and cannot fix a collapsed or broken bed. A topper may soften a firm surface, but deep sagging can continue to affect alignment and comfort.
How can I keep a mattress topper from sliding?
Choose a design with a secure attachment system and check that its pocket fits your mattress. SHOUREN has four-way elastic corner straps, while BEDLORE and WhatsBedding use elasticized or deep-pocket skirts. A correctly sized fitted sheet can also help keep the layers in place; see this guide to topper sizing and back support for more fit considerations.
Can I machine wash these mattress toppers?
Only the listed product details for WhatsBedding and BEDLORE specify machine washing. The other descriptions do not confirm that their foam or covers are machine washable, so check the care label before cleaning. Avoid putting foam in a washer unless the manufacturer explicitly permits it.
How long should a compressed foam topper air out?
Allow 24 to 48 hours for the SHOUREN and OLIXIS toppers to expand after unpacking, as their product details advise. OLIXIS also recommends airing it out before use. The supplied information does not specify an odor timeline, so ventilate the room and follow the package instructions.
